A video model only follows a guide inside the clip length it was trained on, so long
sources are split into shots that fit and run once per shot.
- BFS Shot Planner: interactive Vue timeline (thumbnails, cut-detector curve, draggable
boundaries, split/merge, per-shot reference gallery with upload, per-shot prompt).
Splits at camera cuts via PySceneDetect (adaptive/content, built-in fallback), fixed
length, or by hand; lengths snap to the model grid (H3 17n+5, LTX/Wan 8n+1, 4n+1).
Outputs the shots as a ComfyUI list so everything downstream runs once per shot.
- BFS Shot Unpack: guide frames, references, prompt, length, audio of one shot.
- BFS Shot H3 Conditioning: native MiniMax H3 conditioning per shot (aligned guide,
native reference video, or both).
- BFS Shot Join: concatenates in order, trims each shot to its true length, cross-fades
soft joins with the real overlap frames, returns the soundtrack.
- Queue loop mode: one shot per run stored on disk, auto re-queue, nodes after the join
blocked until the last shot.
