Intended purpose

Subtitle Erase (Region) inpaints a fixed rectangle (region_x/y/w/h) to remove subs or logos. More control than Smart when placement varies slightly or you only target one corner. region_* fields are set by in-node box UI (hidden on sockets). Roadmap also calls for per-frame region tweaks.
⚠️ Current status: no backend, incomplete UI. Run → StageNotImplemented. See roadmap.md.

​
When to use it (once shipped)

  • Subs in a band but Smart fails
  • Remove corner bug without touching main frame
  • Manual fallback from Smart false positives

​
Planned design

  • Stage + snapshot; COMFYTV_VIDEO in/out.
  • Pixel coords like Video Crop, but inpaint instead of discard.
  • Workaround: Video Crop the subtitle band away.
