WanXing video generation glitch: last 5 frames wash out with end frame

LanaKatana4000 · reddit · 2026-08-16

User reports that when using the WanFirstLastFrameToVideo node with a supplied end frame, the last 5 frames of the generated video wash out. If the end frame input is disconnected, the sequence completes without any brightness drift. The user suspects a correlation with the length-in-frames setting (kept as "n-1, divisible by 4") but the issue persists. The community is being consulted for a root cause analysis.
