Hi there, out of the blue, my kdenlive flatpak (25.08.1) stopped working. When i am importing clips the profile won’t get detected, and the clip is only rendered white in the timeline (with no thumbnails). The wierd thing is.. i was just editing the same files the other day, there where no update…

There should be a refresh of the latest version, try upgrading and let us know.

Hey there! Having the same issue. Did you try the appimage version recently? Yesterday I installed appimage version out of curiosity and today I am having the same issue you are mentioning. Problem is yesterday I also got an update to the flatpak version so I don’t know if the problem is caused by…

I think i found the problem : There was an update just yesterday evening which i did not realize. By resetting to the previous commit it is now working again. [Screenshot From 2025-10-05 12-41-31] here you can see the commit i am using now, however, this is still 25.08.01, but this one is worki…

Oh thank God I thought I broke it by trying the appimage version. Okay, I don’t know how to revert commits so I’m just going to stick with appimage version for now until they fix the flatpak with an update. Appimage doesn’t support hardware encoding for some reason so flatpak would be nice to have …

The way to revert the commit is right in my screenshot, bit i will post it here again : sudo flatpak update --commit=9f28077f3e213194be22abf099c44bd21d1c8f57c3b296ba8583690a333dd629 org.kde.kdenlive

Thanks a lot for that. I have just realized that appimage version is much faster when viewing timeline. In configuration wizard it also shows much more recent LLVM version than flatpak version and I mean considerably newer version. Something tells me the flatpak version doesn’t support hardware en…

This was the merged pull request [Screenshot From 2025-10-05 13-05-28] they updated ffmpeg and libmediainfo, i guess it has something to do with that. I think so because the clips are imported with wrong frame size (like 0x1080)

Yup, that seems to be the case. Check this out: [4to2560] It’s asking me to convert frame size to 4x2560 instead of 2560x1440. Ooopsie poopsies as they say :smiley: They should fix it soon.

Yeah, this wasn’t us - looks like flathub pushed out dependency updates themselves and they’ve busted stuff. It’s being looked into. Stick with the older version or the AppImage (which we entirely control so stuff like this shouldn’t happen). [image] monomaniac: Something tells me the flatpak…

That’s reassuring to hear. I couldn’t be sure since appimage version says “no hardware encoder is found” while flatpak version says it’s available and sets Vaapi automatically. In appimage version I cannot even select Vaapi in settings, it’s not available. However, performance is clearly better on …

That could be a problem with the not so savvy user, that is just installing flatpaks by software center, because the updates are happening automaticly. They might not know how to revert to an older commit. Maybe it would be the best if you revert the last update on flathub if possible.

Hi,

Don’t want to hijack the topic but, can you take a look at this if you have the time, too. Appimage version does not support VAAPI Hardware Encoding for some reason. All the error log and stuff is in this post:
