Guide title
Build binary and clipped thresholds with the FFmpeg threshold filter
Coverage
For editors and compositors who want black-and-white or partly clipped threshold images from a clip with FFmpeg. You learn how the four input streams combine to give five threshold styles. Based on the FFmpeg manual only; no command was run.
Example
A hypothetical matte test on a 320x240 clip: binary threshold, then the inverted one; nothing was run.
Useful starting points
- The filter needs four streams; fewer than four gives an input error.
- Colour sources must match the clip size, or you will get a size mismatch.
- If results look swapped, check the stream order: filtered, threshold, min, max.
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.
