What this node does

Audio Meter Overlay renders an animated audio-level meter into a video, reading the video’s own audio track and drawing a moving bar in a corner of the frame. The result is a new video with the meter composited on top — handy for reaction videos, tutorials, or any clip where you want the audio level visible. It takes a COMFYTV_VIDEO (which must have audio) and outputs a COMFYTV_VIDEO. It has a ▶ Run (FFmpeg renders the overlay). To feed native ComfyUI IMAGE/VIDEO in or out, insert a Bridge — see bridges.md.

When to use it

  • Show a visible loudness meter on a talking-head or music clip.
  • Add a broadcast-style level indicator to a stream recording.
  • Give viewers a visual cue of audio dynamics.

Outputs

Tips

  • The meter reads the video’s embedded audio — make sure the clip actually has an audio track, or there’s nothing to display.
  • Size the meter relative to your frame: 400×20 suits 1080p; scale up for 4K.
  • Keep margin clear of any lower-thirds or captions so the meter doesn’t overlap them.
  • Audio Reactive — drive scene parameters from audio energy instead of just displaying a meter.
  • Audio Beats & Notes — detect beats/onsets for on-beat visual events.
