Guide title
Rescue flat, low-contrast clips with FFmpeg histeq
Coverage
For editors with hazy or poorly captured footage that needs a wider tonal range. You end with an equalized clip tuned for strength, intensity and banding. It follows the FFmpeg filters manual and was not run; the manual says the filter is for correcting poor sources, not a general grade.
Example
A hypothetical hazy archive clip compared at the default strength and at a higher one; nothing was run.
Useful starting points
- Washed-out highlights point to the intensity limit being set too high.
- Visible banding is a case for trying the weak or strong antibanding level.
- Equalizing frame by frame can make brightness pump between shots, so compare moving footage before and after.
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.
