Question about video and audio duration in processing

[Tribuzeus]

When the original video is 5 seconds long, and the audio is 30 seconds, the generated video is limited to 5 seconds. Is there a way to implement a reverse loop (where the video plays backward and repeats continuously) so that it matches the full duration of the audio while maintaining lip sync?

Thank you in advance!

if you are using Comfyui to run this use https://github.com/ShmuelRonen/ComfyUI-LatentSyncWrapper

it has node to sync the audio and video (pingpong) .

it will do all works for you

if your OS is linux I can share you a ffmpeg script to sync ..
