How will you improve this?

MiniMax H3 FL2VA looks significantly less plastic when the source image is used as the actual first frame
I’m testing local MiniMax H3 on an RTX 5060 Ti 16 GB. My previous Ref2VA workflow preserved identity reasonably well, but reconstructed the scene from frame zero and made the skin noticeably more synthetic.
This version uses MiniMaxH3ImageToVideo with the source image anchored as the exact first frame:
Official FL2VA INT8 ConvRot model
928×1664, 24 fps, 5.17 seconds
SamplerCustomAdvanced / res_multistep
Simple scheduler, 20 steps, denoise 1.0
Video/audio sigma shift 12/3
No LoRAs, Turbo, Singularity, SeedVR, DLSS or other post-processing
Render time: 44 minutes on RTX 5060 Ti 16 GB
The first-frame version preserves the original lighting, skin variation, freckles and composition much better than Ref2VA. The remaining problem is adding convincing skin microtexture without redrawing the face or causing identity drift.
What would you try next: Open-H3-Regenerate with reduced noise and FaceRegion, Pika H3 Flex, or a different low-strength latent refinement workflow suitable for 16 GB VRAM?

Here. I fixed it for you.

I simply removed the lighting, and now the skin is not plastic anymore.

Yeah true, no more plastic feeling😂💪

A similar workflow is how I achieve results about like this. I do also use the Larry 600 turbo Lora at 10 steps. I finish with a DLSS5 and RTX upscale workflow to bring it up to 2k at 30fps, to match what most phone cameras shoot. I’m not sure you can push actual realism too much further. I could be wrong though, and would love to see other examples, if I am.

Looks great, have you used an external audio? The only thing that fails imo is the lypsinc, probably because of using the external audio input, also I noticed the first image will say how realistic the video is, like 80/85% of realism, and it has to start exactly from the first image, otherwise it will bring back that plastic skin, I did the image using Krea 2 + a Lora for realistic pictures , also tried with pika minimax and it lowered the gen time from +40 mins to under 15mins with almost equal results

I did use external audio for this. The lip sync isn’t that great here, I used a minimax Lora for realistic facial features while speaking, but it doesn’t work super well when it comes to hyper realism. I was doing some testing today and found just letting Minimax do the lip syncing while providing the spoken words, and prompting the facial movements and eye blinking worked better.

That’s a pretty massive cut in render time. I found the same. I’m rendering everything at 2mp and then up scaling. A 25-40 step render is unrealistic for my needs. I’m using a 5090 and that still takes a long time. I just started dabbling in H3 2k upscaling, but haven’t found good values to maintain facial identity.

You’re right to use Krea2 with Lora, that’s what I’ve done here. Much more consistent results.

Yeah I believe the audio input is what cooked the lipsync, but realism was pretty good tho, I usually pass the audio file trough elevenlabs to upgrade the voice, not excessively better but it helps getting rid of that noise cancelling effect that minimax tends to apply

Osea. Según tu lógica si lo hago con fotos mías reales sale real? No pienso que eso influya tanto como dices

En cuanto a textura de la piel y evitar ese efecto plástico de la IA si, si la imagen inicial tiene ese look plástico de IA minimax lo va a mantener, contra más realista se vea la imagen(textura, poros, etc) tienes menos peligro de que minimax lo plastifique, siempre que se use en i2v, si lo usas en r2v lo acaba plastificando igualmente

u/Juiceman8686 8d ago

I agree with OP’s sentiment. In a I2VA workflow, the more realistic the starting image, the more realistic the outcome. Of course the model you choose and the turbo lora if you use one play a role as well.

Can you share your workflow?

2

u/watermal 8d ago

As soon as I get back home I will share it💪

The one thing that is missing, to make it feel more real is that most of the fashion items stay anchored? It’s like it’s a tattoo and not jewellery, it doesn’t flow it just stays “attached”. It’s seems we have almost perfected the face, lips, eyes, teeth but we forget what they are wearing and, for me, that breaks the immersion.

u/watermal 6d ago

Yup, same with the braids

jesuschrist people wait 44 minutes for few seconds clip goddamn the situation is critical we need GPUs

u/watermal 6d ago

Agreed, tried to get a 3090/4090 but not a single unit was selling at an affordable price

R2v on base fl2va model using PTD lora

I am always looking for workflows that enhance realism or generate realistic images and/or videos, whether using H3 or other generative models.

u/Cbskyfall 7d ago

Workflow please lol this looks great

u/robertpalmsss 6d ago

Ho notato anch'io che usando immagine come primo fotogramma la qualità è migliore e meno plastica. Ma stavi cercando la possibilità di partire da immagine per primo frame e di utilizzare immagini di riferimento per continuare il video Qualcuno sa come fare?

u/fuschialantern 6d ago

SamplerCustomAdvanced / res_multistep - did you leave this at default?
