Thank you for reporting. I can confirm the crash. Attached the crash report.

This seems to be either an FFMPEG or an MLT bug.

Please try to reopen the project. Or use a backup: Project -> Open Backup File.

Gracias por la respuesta, actualicé a la última versión (24.08.3) y todo
funcionó bien, pero ya no usaré ese filtro.

Gracias por responder.

Saludos

>> Hmm, I just finished the test script for this effect, and using the 25.12.0 Flatpak on Pop!_OS works just fine. No crash.

> Then close the bug as WORKSFORME. It’s 2 years old and was traced to dependencies we’ve updated multiple times. It can always be reopened if there later is more info about some continuing issue.
