​
What this node does

Demux · Silent Video removes audio from the source and writes a silent video file. Pairs with Demux · Audio Track on the same source: one takes sound, one takes mute picture. Toolbar 🔀 Demux creates both nodes wired together.

​
When to use it

  • Drop original audio, replace with Audio Stage output
  • Picture-only path while IA2V audio comes elsewhere
  • Edit video (Clip / Crop) without touching audio twice

​
How it works

  • Stage + ▶ Run; PyAV silence_video.
  • Video fps / resolution unchanged; audio track removed.
  • Standard snapshot model.

FAQ

Q: Chain with Clip?
A: Yes — order depends on whether you need source audio before demux. Q: IA2V with silent video?
A: Yes — wire audio from another COMFYTV_AUDIO to Video Stage. Q: Re-encode?
A: Usually remux/light re-encode to drop audio; quality largely preserved.
