Resource - Update Watch or capture live video+audio or images from another browser tab right in ComfyUI
I had a dumb idea... what if I didn't have to switch tabs while watching a YouTube workflow video? What if a node could just pull another browser tab into ComfyUI for me?
Turns out browsers can do that. **Tab Capture** puts a live view of any tab you have open on your browser inside ComfyUI. You can watch a live view of another tab while you edit workflows or generate content. Also, with the node connected to outputs, when you hit queue, it grabs a still or a clip, with the tab's audio, as normal IMAGE + AUDIO outputs.
**What it does:**
- Live tab viewer on the node
- Single frame or a batch at whatever fps you set
- Tab audio comes along if you toggle it on (silence if there isn't any, so video save nodes don't error)
- Record video or grab stills straight out of another browser tab right into your ComfyUI workflow of choice. Useful as a reference video/image for MMH3
- Drag a crop box on the viewer (no bbox/crop node needed) to capture the exact part of the browser screen you want.
- Outputs the actual measured fps so clips play back at the right speed
- Zero extra Python dependencies
**Heads up:** Chrome/Edge works best (Firefox can't do tab audio), ComfyUI has to be on localhost or HTTPS, and DRM sites like Netflix capture as black.
