Been working on an LTX workflow + comfy nodes that can extend+loop any amount of videos with genuinely zero seams.
No color pops, no noise drift, audio extends and loops perfectly. You genuinely can't see the seams no matter how hard you look. This is 4 different videos stitched together (the screens in the background changing are part of the actual videos, not the seams).
Extensions and looping happen in latent space instead of FFLF so the model can fluidly blend motion instead of coming to a freeze frame at each extension. This even allows for detail reinjection so that long generations don't lose detail both over time or in subsequent VAE encodes. Will release soon!
Version 3x longer, still no seams: https://www.redgifs.com/watch/soulfullightgoldenrodyellowdungenesscrab
