Guide title
Turn short flashes into fading light trails with the FFmpeg lagfun filter
Coverage
For editors who want sparks, lights or fireworks to linger as a fading trail. You end with a decay value picked by comparing short test renders. Based on the FFmpeg filters manual; it was not run.
Example
A hypothetical fireworks shot rendered at three decay values over the same ten seconds to compare trail lengths; nothing was run.
Useful starting points
- The manual does not say which direction lengthens the trail, so compare short renders rather than guessing.
- Keep decay between 0 and 1; values outside that range give an option error.
- Use a dark background; bright scenes with strong decay smear the whole picture.
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.
