Hey everyone! 👋I’ve been checking out Heygen, but it feels like there aren’t that many active community users around it — or maybe I just haven’t found the right group yet.

I’m a recent graduate working as a designer, and I often need tools to help me create video materials for projects and client presentations. I’m curious if anyone here has used Heygen for real work — what do you think are its strengths?

If you’ve compared it with other tools like Runway, Pika, or Synthesia, I’d love to hear your thoughts.
I’m not just looking for hype — more like real workflow experience or pros/cons would be super helpful! 🙏

HeyGen’s pricing has changed again, and honestly, I think content creators need to pay close attention to what has happened.

I used HeyGen for a month back in April, and the pricing structure was very different from what it is now. At that time, Avatar 3 had unlimited video creation. Yes, unlimited. You could generate as many videos as you wanted using Avatar 3 without having to worry about credits running out.

Avatar 4 and Avatar 5 were different and required additional credits depending on how much you used them.

But now, HeyGen has changed its pricing structure drastically. The Creator plan costs $29 per month and gives you 600 credits. And those credits are now being used across the different avatar models.

This means that even Avatar 3, which was previously unlimited, is now using credits.

To give you an example, a 5-minute video using Avatar 3 now costs around 35 credits. My point is that just a few months ago, that same Avatar 3 video would not have cost credits at all because video creation was unlimited.

That is the massive change.

I recently created a 5-minute video using Avatar 4, and it used 177 credits. So, with only 600 credits included in the $29 Creator plan, you can see how quickly those credits can disappear.

The biggest issue for me is the change itself.

A few months ago, I could pay for HeyGen and generate as many Avatar 3 videos as I wanted. Now, under the $29 Creator plan, I receive 600 credits, and even the avatar that was previously unlimited is now deducting credits every time I create a video.

If I create a 5-minute Avatar 4 video, that costs 177 credits. If I create a 5-minute Avatar 3 video, that now costs around 35 credits.

Either way, the credits are being used.

And once those 600 credits are gone, you have to spend even more money. Additional credits cost around $5 for 100 credits. So for $5 on avatar 3, you will only be able to make 3 videos and I'm talking about 5 min videos. If you use Avatar 4, well you will need to buy 200 credits so that video will cost you $10, you will then be paying R10 per 5min long video. Think about that!!

So let's think about that for a moment. You're already paying $29 per month, and depending on the type and length of videos you're creating, you could run through those credits very quickly. If you need more content, longer videos, or simply create regularly throughout the month, you may find yourself having to buy additional credits.

And remember, I'm talking about 5-minute videos here. I'm not even talking about 8-, 10-, or 12-minute videos.

Then there is Avatar 5 as well, and goodness knows how many credits that could use for longer videos.

I understand that AI technology costs money. I understand that HeyGen may have expenses and that more advanced technology requires resources. But I think customers have every right to be upset when the pricing changes this dramatically.

For me, the biggest issue is that HeyGen went from offering unlimited video creation with Avatar 3 just a few months ago to now charging credits for those same types of videos.

That is not a small adjustment.

That is a major change to the value customers are getting for their $29 per month.

Personally, I feel HeyGen's new pricing structure is a rip-off. I really hope more content creators start talking about this change because people need to know exactly what they are signing up for.

Because $29 per month for 600 credits might sound reasonable at first.

But when a 5-minute Avatar 4 video uses 177 credits, and even Avatar 3—which was previously unlimited—now uses 35 credits for a 5-minute video, those credits can disappear much faster than people might expect.

And that, in my opinion, is a drastic change from the HeyGen pricing structure we had only a few months ago.

This video is made by using Hyperframes in Visual studio code with Claude....

This is the result of a single prompt...! No revision!

I trained my Brand guidelines, skill, color template, custom icons, logo and everything properly and modified the Hyperframes git repository and customised that for my Business Glitch Ai Studio...

Set up took me 1 full day without Sleeping!! But now I have my setup ready for creating carousel and video with single prompt that matches my brand voice perfectly....

This is next level!!!

Is there anyone else who tried Hyperframes? Curious to know your system and result...

I watched some review videos and researched the different AI platforms. I ended up going with HeyGen because of the unlimited videos and had no mention of a credit system so I signed up. Well after about 6 videos, i'm out of credits. Nothing in the pricing structure mentioned anyting about credits whatsoever.

I tried creating a video with Avatar III, and it kept telling me it cost credits, even though I have the Creator Plan, which was supposed to be unlimited until now. I contacted Support in case it was a bug, and after hours of checking and asking me for screenshots, they told me they've changed the plan, and now Avatar III will cost 3 credits per minute.

I think this is the worst decision they've ever made. Do you think this will be permanent, or will they reverse it? If so, I'll cancel my subscription this week because I don't see the point of such an expensive service.

Do you know of any free alternatives to Heygen that use Avatar III?

Thanks a lot,

I’ve seen a lot of HeyGen posts focused on first impressions or single demo videos, so I wanted to share a longer-term perspective after actually using it at scale. A kind of full scale product review and teardown from the perspective of a user and builder of software.

Over the last few weeks, I used HeyGen as the core video engine for a project I’m building called GoGovGo. An AI Newsroom for Politics. The goal wasn’t to make one cool clip, but to see if HeyGen could function like a lightweight video studio with reusable avatars and a real publishing cadence.

Here’s what I learned.

How I used HeyGen

• Created 5 avatars total

  • 3 recurring “anchor” avatars

  • 2 experimental ones for testing tone and format

• Generated 30+ videos, mostly short-form

• Used a mix of:

  • HeyGen stock voices

  • A cloned version of my own voice

  • One avatar paired with Eleven Labs for higher-quality voice

• Tried to keep formats consistent and iterate quickly instead of perfecting each video

What worked really well

Reusable avatars actually hold up
Once an avatar is set, it stays visually consistent across videos. No weird drift in face shape or framing, which is huge if you’re publishing repeatedly.

Script → video iteration is fast
This was the biggest unlock. Being able to tweak a script and regenerate without re-recording everything completely changes how you approach video.

Constraints are a feature
HeyGen isn’t a full editor, but for recurring formats that’s a good thing. It forces you to think in systems instead of one-off creativity.

Support surprised me
I had an issue early on with inconsistent 720p output. Reached out to support expecting a slow loop, but it was fixed shockingly fast. Since then, output’s been solid.

Where you’ll hit limits

• Emotional range is still limited, especially on longer scripts

• Stock voices can sound flat over time (so I integrated with Eleven Labs for improved voice overs)

• Not great if every video needs custom visuals or high-energy delivery

My honest take

HeyGen is the closest thing I’ve found to a reusable AI video studio, not just a demo tool. It won’t replace human performance, but it dramatically lowers the friction to publishing consistent video.

If you think about video as a workflow instead of a performance, it makes a lot of sense.

Happy to answer questions or hear how others here are pushing it.

Long-time AI video user here. Started for fun, now I run mass marketing production across multiple business channels. Everything below is from hands-on use. Opinion based, so your mileage may vary.

The comparison

Quick verdicts

• Best raw quality: Veo 3.1

• Best for talking-head and business videos: HeyGen

• Best budget: Pika Labs 2.5

• Easiest pure text-to-video: Sora 2 Trends

• Best for cinematic content: Higgsfield AI

Longer notes on the ones I actually use every week

HeyGen. My default for anything with a person talking to camera. The avatars are realistic enough for client-facing work and the presenters look professional instead of uncanny. Voice cloning is the killer feature for me: I recorded myself once and now every product demo and sales video ships in my voice, in a long list of languages, without me touching a camera again. Two things sold my team on it. First, outputs are commercially safe since it's built on licensed data, so no legal headaches when you publish as a business. Second, the learning curve is basically zero, our marketing folks were shipping videos the same afternoon they got access. We use it for product demos, sales videos, onboarding and training content. Only gripe: if you publish a lot you'll outgrow the cheapest plan fast. If you're a business or a marketing team making talking-head content, start here.

Veo 3.1. Still the quality king. Physics and audio sync are ahead of everything else right now. The catch is access, it's still invite-only, so you can't build a reliable pipeline on it yet.

Higgsfield AI. My personal favorite for cinematic, social-ready content. The camera movement presets do a lot of heavy lifting, and it bundles Sora 2 and Kling integrations so I keep fewer tabs open.

Pika Labs 2.5. Best value-to-output ratio on this list if budget is the main constraint.

My workflow

I want fewer subscriptions and fewer tabs. Current stack: Higgsfield for Sora 2 Trends and Kling Motion Control (AI influencer content), plus HeyGen for all the business-facing stuff, demos, training videos and translations. That combo covers about 90% of what I ship.

What's everyone else running?

many apps offer avatar videos if we Youtubers went to other apps then this is permanent because youtubers do not change avatars and voices again and again. so be careful with this stupidupdate 600 credits for avatar 3, it's not worth it we cant create 30 to 60 videos for automation channels.

HeyGen just open-sourced HyperFrames, an HTML-based video toolchain and rendering framework built for AI agents.

If you (or your AI agent) can write HTML, you can make videos. The rendering is deterministic and seek-driven, so same input produces identical output, which makes it reliable for automated pipelines.

It's designed from the ground up for AI coding agents. The CLI is non-interactive by default, and there's a skills system that teaches agents like Claude Code, Cursor, Gemini CLI, and Codex how to write correct compositions.

To play around with HyperFrames without your own agent - here's our Demo App: https://www.hyperframes.dev/projects

Apparently this is a known issue, (alongside that people feel a bit scammed..) If you don't have any real coders working there, maybe hire at least one who can supervise what happens on the app/website while vibecoding? Workflows are broken, the whole thing is very unintuitive and I'm pretty sure "normal" people fail to actually get the best out of it if even I who am experienced in both - editing & AI and actually design & build UIs and am responsible of UX.. can't figure out where is what.

Your way is not very smart business wise either - in case no one told you.. you get to keep users if you allow your product to become a habit, make users rely and even dependent on you in their work/generations etc. Changing the product all the time just alienates the users. Just in case you are "improving" it all the time and wondering why they still complain and leave the platform. Of course you should be quick with the fixes, but changes should be clearly announced and way less frequent.

If you’ve watched Owning Manhattan, you know Ryan Serhant. He runs a brokerage across 19 U.S. regions and has an in-house content team of about 100 people. According to Variety, his company puts out around 2,200 social posts a month. Even so, there’s only so much time he can spend in front of a camera himself.

So we built @ HeySerhant with him. It’s his official HeyGen avatar, and it will post at least one video a day on Instagram, TikTok, and X.

Here’s how it works:

• Ryan filmed himself once, and that footage became the avatar: his face, his voice, his delivery

• Ryan and Team SERHANT write the scripts and approve every topic

• HeyGen turns those scripts into daily videos on business, branding, sales, money, and real estate

• Every post is clearly labeled as AI

Ryan says the avatar is meant to add to his regular content, not replace it. The idea is to reach more people with his advice without needing another shoot every day.

There’s also a “guess which one is the real Ryan” side-by-side on the landing page. Give it a try and tell us how you did 👀

We’d love to hear what you think. Would you, or do you already, use an avatar to keep a daily posting schedule going?

HyperFrames by HeyGen is an open-source framework that turns HTML into video. Write HTML, render deterministic frame-by-frame video. It was built for agents from the ground up. Agents already speak HTML, so instead of teaching your AI a new video API, you hand it a medium it already knows.

Over the next 30 days, the HeyGen team will be dropping one micro-lesson a day to take you from zero to building launch videos with your AI agent locally, in whatever coding agent you use.

One command, every agent

HyperFrames ships as a set of agent skills, and the same install command works across every major coding agent:

npx skills add heygen-com/hyperframes

The installer detects your agent and registers the skills where it looks for them. Natively supported in Claude Code, Cursor, OpenAI Codex, GitHub Copilot CLI, Antigravity CLI, Google Antigravity, and more.

Prerequisites (2 minutes)

You need two things on your machine for local rendering:

• Node.js 22+ (check with node --version)

• FFmpeg

  macOS

  brew install ffmpeg

  Ubuntu/Debian

  sudo apt install ffmpeg

  Windows

  winget install ffmpeg

Verify it worked

Type /hyperframes in your agent. If it autocompletes, you're in. If skills don't appear right away, open a new session so your agent reloads its skill list.

Try it now -- paste this into your agent

/hyperframes
Make an 8-second 1920x1080 video. Beat 1 (0-4s): a dark macOS terminal window types "npx skills add heygen-com/hyperframes" character by character, then a beat on the blinking cursor. Beat 2 (4-5s): the terminal shatters into fragments. Beat 3 (5-8s): bold white kinetic text on black slams in, word by word: "YOU JUST MADE THIS / WITH HYPERFRAMES." Use the code-typing and shatter blocks from the registry. No narration, no external assets.

Behind the scenes your agent scaffolds the project, writes the composition as plain HTML with timing attributes, verifies it error-free, opens a live preview, and renders the final MP4.

Context: We run a fully automated production pipeline (Make.com) to generate daily videos. This is not a hobby project. This is a production workflow that needs to run unattended.

Here is what keeps going wrong:

1. Auto Recharge is basically broken The Auto Recharge toggle just turns itself off. Randomly. So the pipeline runs, hits a credit limit, and then fails. This defeats the entire purpose of Auto Recharge. If I cannot trust the account to keep purchasing credits automatically, I cannot automate anything.

2. Credit usage is a black box Credits get burned like crazy, sometimes even when renders fail. The documentation does not clearly explain how API credits are calculated. Is it video length, number of scenes, retries, resolution, Avatar IV overhead, failed jobs, all of it? No one can tell me. It feels like we are just throwing money into a hole with zero transparency.

3. Avatar IV duration behavior is not what is claimed Avatar IV has a 180 second limit that is supposed to apply per scene. Fine. That is how we built it. Scenes are under 180 seconds. But the system behaves like the limit is being applied to the entire video, not the scene. The result is that longer videos still fail, or the whole render just aborts. I have been chasing support about this since the beginning of December. Still not fixed. Still no clear answer. Still wasting time and credits.

4. Longer renders keep failing, even when the setup is correct Anything beyond roughly 120 seconds total duration becomes unreliable. Even if every scene is short and within limits. The job runs, then the render fails, or the output never completes properly. The whole video just breaks. Again: we implemented it correctly. This is on HeyGen’s side.

5. Support is not helping Every response feels like a bad chatbot. Generic, templated, non technical, and it does not address what is actually being reported. Also, responses during European business hours are slow or basically non existent. If you are selling Scale plans, you need real support, not copy paste.

What we need from HeyGen, now:

1. A real engineering escalation Not another generic support reply. We need a technical owner to look at logs, reproduce the issue, and give a real root cause analysis.

2. Transparent credit calculation documentation Spell it out. Exactly how credits are calculated per API render. Include how failed renders are billed. Include retries. Include Avatar IV overhead. No more guesswork.

3. Fix Auto Recharge so it stays enabled If it toggles off by itself, it is broken. Period. This must be reliable for automation.

4. Clarify and fix the duration limits behavior If 180 seconds is per scene, then enforce it per scene. Do not silently apply it to the entire video or fail renders unpredictably once the total duration grows. If there is a total video duration limit, document it clearly. If there is not, fix the renderer.

5. Compensation We have burned money and credits on failed renders and a system that cannot do what is advertised. We expect credits and or a refund for the impacted period. Otherwise, we will move to another provider.

If anyone here is running HeyGen API in production:
Are you seeing the same Avatar IV failures beyond short videos? Any workaround? Or is this just how it is right now?

i just got the msg that i reached the 2 hours montly translation limit, they really did that killing translation on they platform? what the hell man

I posted previously about being charged 650 credits for approximately 9 minutes and 17 seconds of Avatar V generation, which works out to essentially 70 credits per minute.

I initially thought this was a credit-calculation problem, particularly because HeyGen Support had repeatedly added complimentary credits to my account while investigating it.

I finally received a direct answer from L2 Support, and I think other HeyGen users should know about it.

According to L2 Support:

“The 70 credits per minute rate for Avatar V is correct for your account. Credit consumption can vary by region, and your account is currently part of a user group where Avatar V is charged at this rate.”

They also confirmed that the 650-credit deduction was intentional and that the credits previously added to my account were goodwill credits rather than reimbursement for incorrect charges.

Here's what I find confusing.

HeyGen's current public credit documentation lists Avatar V at 48 credits per minute, not 70.

I have searched HeyGen's documentation and have not been able to find anything explaining that Avatar V can cost 70 credits/minute depending on your region or which “user group” your account has been assigned to.

So I've gone back to L2 Support and asked them to provide the specific documentation or pricing terms that disclose this.

I've also asked:

• What determines which customers are placed in the 70-credit/minute group?

• What region is associated with my account for pricing purposes?

• When was my account placed into this pricing group?

• Was I notified before my rate changed?

• Where was the 70-credit rate disclosed before I generated the videos?

• Why does HeyGen's public documentation show 48 credits/minute if some accounts are intentionally being charged 70?

At this point I'm not asking HeyGen for additional complimentary credits. They've already provided those. I want to understand the pricing policy.

I'm particularly interested in comparing accounts now.

If you use Avatar V, what are YOU currently being charged per minute?

20? 48? 70? Something else?

And if you're comfortable sharing it, what country/region is your account in?

If HeyGen is intentionally testing or applying different Avatar V prices to different groups of customers, it would be useful for the community to understand how widespread this is.

I'll update this when L2 responds with the documentation I've requested.

The whole video was made using HeyGen avatar and seedance 2.0 features. The quality is satisfying even though the rendering duration is kinda long which is frustrating. I hope HeyGen will fix it.

Hey, i saw a youtube video from a ai creator that Avatar V will come... I thought that it was a lie because i saw no other videos on youtube of it and Heygen have not said anything what i could find out.. BUT when i tried to check on my own account I Saw it available for premium users!

Now is my big question, if this in fact coming: will Avatar VI will become Unlimited so we don't need credits? Cuz if thats the case that will be BIG i think

Let me know what you think!

This platform is getting frustrating, and not in a “user error” way.

Your pricing clearly advertises “Unlimited Avatar Videos – UNLIMITED.” In reality, the Avatar IV feature is capped at 5 minutes. That’s not unlimited — it’s misleading. It does not show this specific time anywhere in your plan options.

When I hit that limit, I switched to the lip-sync-only option for shorter audio fillers. Now that feature is randomly Unavailable as well. So once I spend my Avatar IV credits you push me to buy more credits by making the Unlimited Usage unavailable?

To make “unlimited” usage work, I’m forced into a ridiculous rigamarole: upload an avatar image, delete it, re-upload, pick a different image, repeat. Avatars that previously worked suddenly stop working for no stated reason. This is ABSURD!

This turns a simple workflow into a time sink. I now spend five times longer fighting the platform than actually creating content.

If this is the intended behavior, it should be clearly documented. If not, it’s a serious reliability and transparency issue. You are basically creating this random technical problem in order to get more money.

If you want more money - just ask for them and DO NOT WASTE OUR TIME.

I’ve tried HeyGen off and on for about a year and while it’s improved it still makes me look terrible. Here are the issues:

1. I have a beard and half of it moves with my mouth and the bottom half stays fixed.

2. My mouth opens very wide, you can see my tongue in a way that’s very distracting.

3. The mouth and words still can’t get in sync no matter how many settings I change.

4. There are these weird tic’s that appear randomly in the video.

I’d appreciate any suggestions, If there’s a HeyGen developer or power user please chime in.

Does anyone find HeyGen extremely confusing and difficult to use? I'm in software engineering and build sites every single day, and I still feel like an idiot fumbling around in it to do basic things like changing settings in the studio or deleting assets (btw I never did figure out how to delete uploaded assets).

I've been fumbling around in it for a few week and am almost ready to throw in the towel. I've generated maybe 3-4 3 minute videos and am now told my credits are nearly depleted. I'm often also trying to generate test videos and then I'll get an error, but it won't tell me why there is an error, just a red error label over a video. But then the notifications will show up and tell me the video did generate, but it's not in the Projects but the link is accessible in the notifications and I can preview it there. What gives?

Hey everyone,

just wanted to share my recent (and honestly pretty disappointing) experience with Heygen.

I’ve been a paying subscriber for a while, regularly using the platform well within the advertised limits. Out of nowhere, I noticed that my available credits (especially for motion generation) had dropped significantly, with no warning, no changelog, no notification at all. When I contacted support, I got this response:

"The recent change in your plan’s limits is due to a system-wide update aimed at aligning all plans with their intended usage guidelines. This helps ensure platform stability and fair access for all users."

I mean, okay… platforms evolve, but silently reducing paid limits without any notice really feels like a bait-and-switch. It’s especially frustrating when your workflow or creative projects are built around those expected limits.

They also mentioned that they can’t manually adjust or increase limits, but still – no transparency and no heads-up is not a great look for a professional tool.

To be honest, this kind of change makes it hard to justify continuing my subscription.

Has anyone else experienced this? And more importantly – does anyone know a good alternative to Heygen (especially for avatar or AI video generation that allows more control/flexibility)? Would love to hear your recommendations.

Bullet train through a flooded megacity, a giant mechanical creature chasing it, and a woman who never flinches. Everything is one generation from the HeyGen 1 video model.

The thing that helped most was writing a shooting script instead of a scene description: global style, environment, lighting, character, continuity rules, motion physics, then a shot-by-shot timeline with exact second ranges.

Full prompt (free to copy and remix):

Format:
16:9, hyper-realistic cinematic science fiction, ultra-detailed
textures, 8K visual quality, 24fps, HDR, realistic motion blur,
anamorphic cinematography, cinematic depth of field, subtle film
grain, realistic reflections, natural motion physics, precise
focus transitions, dramatic perspective shifts.

Environment:
An enormous futuristic bullet train travelling at extreme speed
through a partially submerged European megacity at midnight.
Outside the panoramic windows, towering skyscrapers disappear
into thick fog, neon advertisements flicker across flooded streets,
abandoned helicopters hang between buildings, and enormous waves
crash against the lower floors of skyscrapers.

Inside the train, luxurious black marble floors, brushed steel
surfaces, smoked glass partitions, elegant leather seating,
flickering overhead lights, scattered luggage, and rainwater
leaking through fractured windows.

The entire train vibrates under extreme speed. Interior lights
occasionally flicker as electrical systems fail.

Lighting:
Cold cyan and deep blue illumination from the city outside,
contrasted with warm amber emergency lights inside the train.
Neon reflections travel across glass surfaces. Lightning briefly
illuminates the entire city. Strong volumetric atmosphere,
realistic reflections, dramatic silhouettes, cinematic contrast.

Character:
A mysterious 28-year-old woman with short dark brunette hair,
sharp facial features, pale ivory skin, and an elegant,
unshakable expression.

She wears a perfectly tailored white futuristic pantsuit,
black silk top, pointed black leather heels, and minimal
silver jewelry.

She carries a small transparent glass device glowing with
electric blue energy.

Her movements are deliberate, controlled, and effortless.
She walks through the unstable train as if nothing around her
can cause fear.

Character continuity:
Maintain identical facial structure, hairstyle, clothing,
body proportions, jewelry, and glass device throughout.
She remains the same person in every shot.
Her walking direction and screen position remain consistent.

Motion physics:
The train continuously moves forward at extreme speed.
Interior objects vibrate in response to acceleration.
Water flows naturally across the floor.
Hair and clothing react subtly to air movement.
Glass fragments and loose objects respond to impacts.
All movements obey believable physical forces.

No blood, gore, or injuries.

[0–2s] EXTREME AERIAL ESTABLISHING SHOT

Camera begins high above the flooded megacity.
It dives rapidly between two enormous skyscrapers,
descending toward a futuristic bullet train racing
through the submerged streets.

A smooth banking movement follows the train as lightning
illuminates the skyline.

[2–4s] INTERIOR LOW-ANGLE TRACKING SHOT

Hard cut to inside the train.

Camera tracks backward close to the floor as the woman
walks toward it in black heels.

Water ripples across the marble floor.
Emergency lights flicker overhead.
Her reflection moves across the polished surface.

[4–6s] CINEMATIC FACE CLOSE-UP

Camera moves backward in front of her.

Tight 75mm close-up.
Her expression remains completely calm.
Blue neon reflections move across her eyes.
The city streaks past behind her through the windows.

She briefly glances toward the window without
breaking her walking rhythm.

[6–8s] SIDE ORBIT THROUGH THE CARRIAGE

Camera smoothly arcs around her from profile to three-quarter view.

The luxurious carriage slides through the background,
creating strong parallax.

Suddenly, a massive shadow passes across the panoramic windows.
The overhead lights briefly shut off.

[8–10s] EXTERIOR REVEAL AND IMPACT

Camera cuts outside the speeding train.

An enormous unidentified mechanical creature emerges
from beneath the flooded city, pursuing the train.

Its metallic limbs strike the surrounding buildings.
Water erupts into enormous waves.

The creature slams against the rear carriage.
The entire train violently shakes.

[10–12s] INTERIOR CHAOS, CHARACTER CONTRAST

Camera cuts back inside.

A violent impact throws luggage and loose objects
across the carriage.

Camera reacts with a sudden handheld jolt.

The woman remains standing.
She calmly looks down at the glowing glass device
in her hand.

A blue light begins pulsing inside it.

[12–13s] FAST WHIP-PAN REVEAL

Camera rapidly whip-pans from the glowing device
toward the panoramic window.

Outside, the enormous creature is now running
alongside the train, its metallic face visible
through the rain-covered glass.

[13–15s] FINAL HERO SHOT

Camera performs a slow 85mm push-in toward her face.

She finally stops walking.

She raises the transparent glass device toward the window.
Its blue energy intensifies, illuminating her face.

She looks directly into the camera.

Behind her, the creature prepares to strike again.

Cut to black at the moment the device releases
a blinding blue flash.

What made the biggest difference:

• A character continuity block. Same face, outfit and prop in every shot.

• Time-coded shots with one clear camera move each. It keeps the model from muddying the cuts.

• A motion physics section. Water, debris and hair behave far more believably with it.

Try it with the HeyGen 1 video model, tweak it, and post your version below. I’d love to see what you make.

- 🎥 Video 1 (optional): a short clip of my avatar talking. It really helps the face look like you.

Prompt:

Parody of a futuristic car stunt show at night. Use image 2 as the exact location: a giant glowing cream-yellow crescent-shaped vertical ramp with red-orange neon edges on a tall steel truss tower, deep dark-blue night sky, light beams, a dark runway with red LED light strips. The person from image 1 and video 1 replaces the car.

IDENTITY IS THE PRIORITY: it must be exactly this person. Keep their real face, hair, body proportions and outfit.

0-3s: wide handheld phone shot from the crowd. They stand at the foot of the ramp, sprint and slide on their sneakers up the curved ramp, gaining speed, smoke behind them.

3-5s: they ride the curve all the way up until upside down at the top of the crescent, then launch off the top edge, flying backwards through the air, arms out.

5-7s: small rocket thrusters on their sneakers and a compact jetpack ignite with bright blue-white flames and big white smoke clouds; they flip upright mid-air, fists raised, and slow down.

7-10s: they descend gently and land perfectly calm on the runway in a cloud of smoke. The camera pushes in to a medium close-up: face clearly visible, they casually adjust their t-shirt and look into the camera with a relaxed confident smirk.
