This workflow is to extend Wan 2.1 video generations endlessly without needing extra VRAM/RAM. Had some questions on my extended facials videos, and unfortunately combining via ffmpeg strips out the workflow. This is a real hacky approach so not for beginners. It doesn't have to be used for facials only that's just what I refined for the loras and prompt, it could be for anything that has repeated action (endless cowgirl?).Instructions:STEP 1: Place your starting image in your /output directory, with no other images thereSTEP 2: Set the incrementing integer to 0 in the input image loading stageSTEP 3: Queue as many iterations as you want, after 4 quality starts to degrade quicklySTEP 4: Confirm the sequential .mp4 files are in the output folder, and paste this ffmpeg script into the command line in that folder in order to concatenate them all into one large file:(for %i in (*.mp4) do @echo file '%i') &gt; mylist.txtffmpeg -f concat -safe 0 -i mylist.txt -c copy combined.mp4If you get the "list index out of range" error then you forgot to reset the increment INT to 0Any diffusion model or GGUF should work, including 480p. I am not able to fit 1280x720 on my 12GB VRAM but here are the resolutions I've had good luck with:720P: 576x1024480P: 480x832, 480x640, 360x480TODO:- Improve image batch logic so you don't have to reset to zero each time- Concatenate video files in the workflow

Wan Endless Facials

v1.0: relies on manually resetting increment INT and manually combining videos with ffmpeg afterwards
