Free workflow
Flow Extend — seamless longer takes
Extend a take without a visible join.
Two H3 takes that play as one shot. Take 2 starts on the last 39 frames of take 1's own sampled latent, locked with a noise mask, so there is no brightness step or flicker at the join. A colour-match pass holds take 2's grade to the last frame of take 1, so the colour doesn't drift either. Every take's latent is saved beside the clip, so you can extend it again any time at full quality. Gmanski's own H3 Long nodes, no third-party packs.
Drag the .json onto ComfyUI. Runs best on the Gmanski RunPod template.
