ComfyUI-Pixaroma

Save Mp4 Pixaroma - encode an IMAGE batch (and optional AUDIO) to a single H.264 mp4 with a built-in <video> preview right on the node body so you can watch the result without leaving ComfyUI.

Frames stream straight to ffmpeg's stdin (no temp PNG files); audio is muxed in as AAC 192k. Pairs with AudioReact Pixaroma but works with any source that produces frames + AUDIO.

The workflow is embedded in the saved mp4 (its comment metadata), so you can drag the video back into ComfyUI to restore the graph - reading it back needs a video pack like VideoHelperSuite installed.

ffmpeg binary is auto-located: imageio-ffmpeg's bundled exe is preferred (no system install needed - 'pip install imageio-ffmpeg'), with ffmpeg on PATH as a fallback. yuv420p requires even width and height; the node surfaces a clear error rather than ffmpeg's opaque crash if dimensions are odd.

Encoder is hardcoded to libx264 / preset medium / CRF 19. Bring those back to INPUT_TYPES if a workflow needs per-clip control.
