What this node does

Make Proxy takes a source video URL and transcodes it into a smaller, easier-to-play proxy clip. On ▶ Run the server builds the proxy (via the proxy runner) and returns a COMFYTV_VIDEO reference to it. It reports progress while transcoding. Unlike the other editing nodes, its input is a plain video string — a source /view URL — rather than a COMFYTV_VIDEO socket. Give it a real URL or the run errors out.

​
When to use it

  • A large or high-bitrate clip stutters when you scrub or preview it — make a proxy to edit against smoothly.
  • You want a fast-loading stand-in for a heavy source while building a sequence.

​
Parameters

​
video

The source /view URL to build a preview proxy for. Must be non-empty. This is a string input, not a COMFYTV_VIDEO socket.

​
Outputs

​
Tips

  • The proxy is a preview-quality stand-in; use it for editing/scrubbing, and keep the original source for final output.
  • If nothing happens, check that video holds a valid source URL — an empty value raises an error.

​
Bridge note

COMFYTV_VIDEO is a project snapshot reference, not a native ComfyUI tensor. To move between ComfyTV and native ComfyUI nodes, insert a Bridge (ComfyTV/Bridge). See https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md.
  • Video Clip / Video Split — edit against the smooth proxy.
  • Video Resize — set an explicit output size if you need a specific proxy dimension.
