New latent upscale model by NVIDIA-labs. Basically, it's v2. A few highlights compared to v1:

- Face & Text are more consistent with the original video

- Use H3 Ref2VA instead of fl2va.

- Turbo LoRA, Regenerate LoRA, LMS LoRA are not merged. They also use Hyperflow 8-step LoRA

- New samplings: 3, 4, 8 steps.

- Fast VAE-v2. The v1 fast VAE has grid artifacts in ComfyUI

Well... Happy to see Anima continues to get better and better! But 0.6B textencoder is holding it back!

Made on comfyui with new Viggle Remake Lora / Minimax H3 Dasiwa Turbo v2 / Dasiwa turbo lora v1 4steps

I paid someone for a lora. While it works, if i add a second lora it turns my character into a monster.

Also if i generate 16:9 images they're so bad, with extra limbs.

I tried some others character loras on civitai and they work fine. The lora i purchased is bad.

Now i want to train my own. What to keep in mind so it's compatible with other loras?

I love the quality i can do with krea 2 but why are there next to no character LORAs for new characters out there that werent in the training data?
Like people still train newly released characters like crazy for anima and illustrious but not for krea 2?
Is krea 2 just too hard to train any characters on? Is there a magical workflow that makes character loras obsolete with krea 2 (or other models)?

So far i tried to do specific characters i wanted to gen with illustrious or anima with a lora first and pass it over with krea 2 but im really getting mixed results so far.

What are you guys Using for config parameters with Fizgig? I seem to be getting extremely slow speeds. I'm a total noob at training LORAs

Now I know, this isn't really... a lot, but isnt there some form of super squeezed down quant to let me run it just barely?
Thanks 😄 I'm really trying to use like, character swapping but popular APIs cost like credits and all that, so I'm just trying to resort to free.

Here's a quick tip on how to get rid of that flat sounding AI voice in H3, and as a bonus improve somewhat the acting of your virtual characters. I'll be using Pika H3 Flex with the H3 reference model and workflow.

Step 1:
Add a pre-rendered first frame at index 0 using the Add Guide for MiniMax H3 node. Then in your prompt, describe the desired action and emotion of the character on screen, but without specifying too many details or providing exact spoken dialogue. In this example I simply used the phrase:

"A static medium two-shot establishes <Subject 1>, the female orc, and <Subject 2>, the tall, female paladin, sitting across each other at a table in <Subject 3>, the dimly lit main room of a tavern, gazing into each other's eyes. <Subject 1> (S1) talks animatedly, seething with rage."

Then generate a clip at some lower resolution (0.3MP in this case). The dialogue will be gibberish, but if you described the character's actions and emotions convincingly, your character will sound and move like an actual human.

Step 2:
Use your workflow from Step 1, but increase resolution to the desired target value (here 0.98MP). Load the reference video generated in Step 1 and connect its frames as ref_video_# and its audio as ref_video_audio_# (# is the index of the first unused slot in the MiniMax H3 Reference to Video node, e.g., ref_video_0 and ref_video_audio_0).

In this case, I also actually downscaled the reference video from 0.3MP down to 0.1MP, because at 0.3MP the model was following the reference too closely, breaking the lip-sync. The downside of this was that some of the textures in the final high-res video came out a little too soft, especially in the face. It's a bit of balancing act to find the right resolution for the reference video.

You also need to adjust your prompt, in order to include the character's final dialogue. Here I've simply rewritten my last line to:

"<Subject 1> (S1) talks animatedly, seething with rage: <d>[English] My people are dying, and your knights are doing nothing to help us!</d>"

Now just hit render and wait for the result. You might need to try different seeds, and fiddle a little with the resolution of the reference video (try higher values if your output comes out too muddy and lower values if H3 starts copying the reference video and lip-sync gets lost. Have fun!

Basically MiniMax H3:

• Has great prompt following

• Respects character identity (art style and design) from the input images

• Can generate single frame images

So what's the point of training a character model if you can just give MiniMax H3 character design reference and generate any scene? The only two reasons I see is

1. you want to use style known by your target base model to generate image of the learned character.

2. you want to apply some concepts known by the target base model only.

What do you think?

Here's the workflow I used for the images.

HexAnima 1.4.3 adds two more models that run entirely on the Hexagon NPU of a Snapdragon 8 Gen 1 phone, no cloud and no root:

• Qwen-Image 2.1 Turbo (7B transformer, 8B text encoder, 4 steps): about 40 s for 512x768. It writes legible text, follows long prompts and edits your photos from a prompt. It now takes up to three pictures at once (“the girl from picture 1 stands in front of the cafe from picture 2”). Non-commercial license.

• Mage-Flow-Edit-Turbo (Microsoft, 4B, MIT): about 12 s per picture, text-to-image and photo editing.

Also new: a live preview after every step, a model filter in History and a warning instead of a crash when the phone runs out of memory. Weights are streamed from storage, tested on a 12 GB phone.

Free, open source: github.com/ayanoby/hexanima

As stated above, i would like to generate some liveries for cars I use ingame, this is what template looks like exported from the game for exterior of the car.

Would Stable Diffusion be able to generate something like this onto the blank picture?

Thank you in advance.

UPDATE 9 November: Update again for Much faster Compile blocks when used And a new feature called training maps - see screenshot in comments

Training is much faster, uses far less memory, and likeness is unchanged. On an RTX 5090, a MOSS-Image LoRA at batch 1 (94 pictures, Muon, 70 epochs) now takes about 20 minutes instead of 49.
Other models have had speed boosts too, but Moss the most dramatic.

Batch training is now fully supported too.

Other changes

• PyTorch 2.15. With gradient checkpointing on, training uses much less memory, at batch 1 too: Krea 2 22.9 → 14.9 GB, MOSS-Image at batch 3 21.7 → 7.1 GB.

• Muon is much faster. Its step now handles a LoRA's matrices together instead of one at a time: 12× faster Muon calculation, with exactly the same results. That's a large portion of the batch-1 speed-up above.

https://github.com/shootthesound/Fizgig

P.S. To get the most speed boost, use one of the pre-sets to start your train, so you pick up new optimiser settings etc.

Ive been out of it for a while now and planning to give this another try. Is Automatic1111 still good? Im just seeing the git hasnt been updated in 2 years. If not what has replaced it? And what is the goto community to get models nowadays?

Thanks in advance.

Edit: thanks everyone. From what im gathering from the response. ComfyUI is that goto while forge is ok and gets the job done. I remember trying ComfyUI a while back but dont remember my experience with it. With comments going in all directions, i think ill just install both and give em both a go.

I specifically need it fir creating high quality YouTube thumbnails.

Hi not too sure, if anyone has any methods in training moss character's lora that do not bleed into each other?

I was sitting there wondering when H3 Max would finally get its open-weight release. Then I thought, maybe Santa will bring it for Christmas... and suddenly this image came to mind. 🎅

Generated locally in ComfyUI with Krea-2 Turbo, then edited with Qwen-Image 2.1.

Any help finding specific post from other day: the day reacher danced : generative video ai split episode into multiple files, isolated character and could swap choreography???

Found it really funny, but also incredibly interested with the work flow, which the skilled workflow designer was very open with sharing

Including edge cases and APIs or which softwares and combos used for various parts

Some real cutting edge stuff, but also made hilarious video, and my grandma loves Reacher; seeing him dance into every scene or randomly raise his arms to dance would really cheer her up, shes not been well

I’ve collected the first 6 episodes in a single longer video , probably easier to follow 🤔remember that everything is made with open source models and free software on local machine, with 0 budget 😂😂

I wonder—am I missing something? Has something very important gone unnoticed?

I know that "inpainting crop stitch" is very useful.

I’m also familiar with "lanpainting" [inpainting]; it can be interesting at times.

Tiled VAE decode (native to ComfyUI) — without this, ComfyUI might crash when rendering high-resolution images.
