Video Save Plus (Custom Path) 🎬 — v2.0.1
Saves a video with its generated audio (MP4, H.264/H.265 + AAC) to any folder
on any drive, plus a workflow PNG, an optional prompt .txt and optional frames.
Built for models with native audio (e.g. MiniMax) as well as classic
IMAGE + AUDIO workflows.
v2 is a rewrite. The node name changed to
VideoSavePlus; oldVideoCombineCustomPathworkflows must be re-wired once.
v1 wrote audio through torchaudio.save and silently dropped the audio track
when that failed (which it does on newer torchaudio versions). v2 pipes audio
as raw PCM and frames as raw RGB directly into ffmpeg — no torchaudio, no temp
PNG sequence — and fails loudly if an audio input cannot be processed.
video_00012.mp4 ← video with audio
video_00012.png ← first frame + embedded workflow (drag & drop into ComfyUI)
video_00012.txt ← prompt (only if prompt_text is connected)
video_00012_last Frame.jpg ← via button or save_frame option
video_00012_first Frame.jpg ← via save_frame option
All files share the same base name; the counter is appended automatically.

Every field has a tooltip in the node.
Output: filepath — the full path of the saved MP4.
- Reveal in file manager — opens Explorer/Finder with the last MP4 selected.
- Open video (with sound) — plays the last MP4 in the system player.
- Save Last Frame — writes
name_last Frame.jpg/pngfrom the frame kept in memory (lossless, instant). Falls back to a single ffmpeg seek if ComfyUI was restarted in between. - Save Training File — copies the whole set (mp4 + png + txt + frames) to
copy_to_folderwith identical names. - Delete Last Generation — deletes the whole set after confirmation.
After each run the node shows resolution, frame count, duration, size and an
audio status line (✓ Audio: 48000 Hz stereo, 5.00 s or ⚠ No audio), plus an
inline player with sound.
Security: the server endpoints only operate on files this node saved during the current session — never on arbitrary paths from the browser.
Search for Video Save Plus and install.

Requirements: ffmpeg on the PATH (or pip install imageio-ffmpeg).
No torchaudio needed.
