Video Crop

Video Crop · screenshot coming soon

​
What this node does

Video Crop applies x, y, w, h (pixels) identically on each frame — like Image Crop but for the full clip. Removes letterbox bars, fixed overlays, or dead zones. It does not run text/image-to-video workflows. PyAV re-encodes the cropped region on disk; no GPU.

​
When to use it

  • Remove letterbox padding
  • Fixed ROI before Resize to standard resolution
  • Cut bottom subtitle band (proper erase: Subtitle Erase — pending)

​
How it works

  • Stage + ▶ Run; upstream video snapshot.
  • PyAV crop_video; preserves fps and timeline.
  • Rectangle must fit source frames; even w/h preferred for encoders.

FAQ

Q: Crop outside frame?
A: Error or clamp; keep x+w ≤ width, y+h ≤ height. Q: vs Subtitle Erase (Region)?
A: Crop is geometric; Region erase (⏳ pending) inpaints subtitles with box UI. Q: Frame rate changed?
A: No.
