Save Video

Encodes a frame batch to an H.264 mp4 in the output folder and shows the result on the node. The current workflow is embedded in the file, so a saved video can be dragged back into ComfyUI to restore the graph that made it.

The responsive player is owned by AusBoss rather than stacked on top of a core preview. It reports encoded dimensions, fps, frame count, and duration, keeps portrait video contained, and includes LOOP and ↻ controls. There is exactly one saved-video surface per node.

Controls

• frames: BHWC frame batch to encode. Odd dimensions are cropped down one pixel to the even sizes H.264 requires.
• fps: Playback frame rate. Wire Load Video's fps output to keep the source timing, including fractional rates like 29.97.
• filename_prefix: Path under the output folder; subfolders are created automatically.
• crf: H.264 quality — lower is better and larger. 19 is visually lossless for most content.
• audio (optional): A track to mux into the file, e.g. Load Video's audio output.

Output

One .mp4 file per run. Audio and video land in a single file — there is no separate audio-less copy.
