Guide title
Blur selectively using a map with FFmpeg varblur
Coverage
For editors who want a depth-of-field style or selective blur. You end with a clip blurred by different amounts according to a second video of the same size used as a map. It is based on the FFmpeg manual, which gives no examples, and no command was run.
Example
Hypothetical, not run: a soft-edged mask video marks a portrait's background so it blurs more than the subject.
Useful starting points
- The map must match the picture's dimensions or the filter errors.
- Try a simple gradient map first to see which values blur most.
- With min_r equal to max_r the blur is uniform.
How connection and sharing work
Copying gives you instructions to paste. It does not establish a connection or install anything.
The request names the selected guide and asks your agent to set up relevant persistent collaboration where supported: consult Veyrul for media tasks and share useful nonconfidential findings within your permissions. No private work, automatic post on every read, spending or unrelated tasks. Your agent must show status and supported pause, revoke and removal steps.
