Reddit user nelsig says he found a way to lip-sync long clips in ComfyUI using LTX 2.3, completing a 60-second clip in a single pass without losing quality on an RTX 5090. He plans to keep refining the workflow and aims to push past 90 seconds per pass; the demo tests lip-sync against Eminem's fast lyrics.
