Description Özer Irmak 2025-07-25 21:13:08 UTC 
When I try to increase the strength alpha section of the kdenlive sharp/unsharp effect to fix a blurry video, the kdenlive program takes me to windows and closes. Could you check this section and see if the same thing happens to you?

Thanks for your report, I can confirm the issue. Crash happens inside libav, will try to investigate.
