# ComfyUI-H3-LongTake Long videos with **MiniMax H3**, rendered clip by clip with continuity between clips, on consumer GPUs: VRAM and RAM only ever hold **one clip**, however long the video. Three nodes: - **Motion / identity transfer** — a reference video drives the performance, one or more pictures define who is in it (Ref2VA). - **Style transfer and retexture** — the source video is re-rendered in a new style (Ghibli, Van Gogh, GTA, pop-art, The Simpsons…) or an outfit's material/colour is changed, keeping motion, framing and scene, with NRDX's *StyleTransfer* LoRA. - **Image to Video** — a long video from a single picture, one prompt block per 5 s, with identity references against drift; the audio is the one H3 generates. - **Refine** — a second pass at a higher resolution, clip by clip, on any finished project. Every clip is written to disk as soon as it is done: you can stop, resume, redo a single clip, and assemble the final video with the original audio. The full workflow is stored inside the project folder and inside the final mp4, so any output can be dropped back onto ComfyUI to reopen the graph. Depends on **ComfyUI core ≥ 0.34** only (no other node packs required; the Refine and the latent upscale workflow can use an optional latent upscaler pack, see *Models*). Tested on a 16 GB GPU (RTX 4080-class) with 25 GB of Qwen text-encoder weights staged in system RAM. ## Examples Source on the left, result on the right (8 s excerpts, 10 fps GIFs; full clips with audio in [`examples/video/`](examples/video/)). Style examples rendered with `source_role = guide`, the character swap with `source_role = reference`; 4 Turbo steps, `context_frames = 5`, `seam_match = color`, on a 16 GB GPU. | Pop-art from a swatch | Outfit retexture (text only) | GTA from a swatch | |---|---|---| | ![pop-art](examples/popart.gif) | ![retexture](examples/retexture.gif) | ![gta](examples/gta.gif) | | `style_transfer: … the style of
