Guide title
Swap or duplicate colour planes with FFmpeg shuffleplanes
Coverage
For editors debugging a clip with swapped or odd chroma, or wanting to look at one plane. You end with a clip whose planes are reordered or repeated. Based on the FFmpeg filters manual and not run; plane meaning depends on the pixel format.
Example
A hypothetical clip with swapped red and blue tones is tried with the manual's swap of the second and third planes; nothing was run.
Useful starting points
- With no maps given the output is unchanged, so no visible change usually means an identity mapping.
- Odd colours usually mean the plane order does not match the pixel format; check the format first.
- Asking for a plane the format does not have gives an error; use an index that exists.
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.
