Open-source EffectCraft panel runs ComfyUI workflows directly on a video timeline

HomoLapis · reddit · 2026-10-29

A new open-source (GPL-3.0) panel runs ComfyUI inside the EffectCraft compositor: place placeholders or markers on the timeline, each bound to its own workflow and prompt. The panel reads your saved ComfyUI workflows, converts them to forms, fills size/duration/fps from the comp, and returns results as new layers with versioning — local or Comfy Cloud. Shipped presets include shot-to-shot transitions (MiniMax H3 or Wan 2.2), Wan 2.1 VACE reframing, SeedVR2 upscaling, SAM 3 cutout, LTX-2.5 extension, and RIFE/FILM slow motion.
