what is comfyui-sequencer fr?

ComfyUI-Sequencer is a custom node for ComfyUI, the visual workflow tool used to build AI image and video generation pipelines. It adds a Video Sequencer node that joins video clips end to end into one continuous video, either from loaded MP4 files or from clips generated earlier in the same workflow. The tool was originally built for a common video generation pattern: chaining clips where each new clip starts from the last frame of the one before it, so a hard cut joins them invisibly. That mode is called cut, and it uses FFmpeg to copy the video stream directly without re-encoding, which keeps the join instant and lossless. Beyond invisible joins, the same node supports creative transitions such as dissolve, fade to black or white, wipes, slides, zoom, blur, and iris style circle transitions. When clips are compatible, only the few seconds around each transition point are re-encoded, while the rest of the footage is copied without quality loss. Users connect up to 20 video clips in playback order, pick a transition style, and queue the workflow to produce a single output video. Clips with different resolutions or frame rates are automatically scaled and letterboxed to match the first clip. Audio is preserved when present, with crossfading during transitions and silence added under clips that lack sound. An additional Spill Clip to Disk node writes generated clips to temporary files as soon as they are created, which reduces memory use in long workflows with many clips. Setup requires ComfyUI version 0.24 or later, plus FFmpeg and FFprobe available on the system path. No GPU is needed for the sequencing step itself. Installation is a simple git clone into ComfyUI's custom_nodes folder, with no additional Python packages to install. This project is aimed at people building AI video generation workflows in ComfyUI who need to stitch multiple clips together, for continuous long form output or for adding stylistic transitions between separately generated scenes.
