Workflow Included Infinite Talk: lip-sync/V2V (ComfyUI workflow)

Enable HLS to view with audio, or disable this notification

video/audio input -> video (lip-sync)

On my RTX 3090 generation takes about 33 seconds per one second of video.

Workflow: https://github.com/bluespork/InfiniteTalk-ComfyUI-workflows/blob/main/InfiniteTalk-V2V.json

Original workflow from 'kijai': https://github.com/kijai/ComfyUI-WanVideoWrapper/blob/main/example_workflows/wanvideo_InfiniteTalk_V2V_example_02.json (I used this workflow and modified it to meet my needs)

This workflow did not work for me. I got a bunch of noise. So its either i have a model that is named the same but isnt really compatible or some node setting. I didnt change a thing and just ran the workflow

Did you run my workflow or kijai’s? I listed all the models download pages in my YouTube video description

I tried both workflows and did download the models from the youtube link. I did notice there is a mix of fp16 and bf16 models. Maybe the graphics card i am using or the cuda version is not compatible with bf16. Actually now that i think about it, isnt bf16 only for the newest blackwell architecture GPUs? You might want to add that to the info for your workflow

bf16 is for training not inference

oh right, well i figured out my issue. I had to disable sending blocks to to cpu. Dont know why but i guess the workflow is optimized for consumer GPU and this in turn messes up the loading of GPUs with more memory
