Kdenlive random freeze issues

I’m having issues where kdenlive will randomly freeze. If I go into the project’s settings and try to adjust the framerate for the project, it will sometimes work, and then sometimes kdenlive freezes solid.

If I can get past that phase sometimes I’m able to import media just fine, other times it’s frozen. Lately it’s a minor miracle if I’m able to finish a video editing project. Somedays it works fine, most of the time it’s freezing constantly.

I’m current running Plasma on Fedora 39, but I have had the exact same issues under Kubuntu.

  • Kdenlive version?

  • Kdenlive Flatpak, AppImage or installed from your distribution’s repositories?

Makes me think it could be harware related.

To add further to what @schwarzerkater requested, please also provide output from inxi -Fazy (or something similar)

kdenlive version is 23.08.5. This is installed from the Fedora repos. It actually is worse under Flatpak.

Here is your output,

I changed back to Kubuntu due to other issues, and this problem is still there. The installed version from Ubuntu is 23.08.1. The flatpak version appears to be the newest, but same problems. I try to import media for editing and it freezes, I try to change my project settings and it freezes.

I’m currently on Kubuntu 24.04 and still have the same freezing issues. Does not matter if I use the Flatpak version or the ones from the repo. I’ve tried other video editors and I cannot get anything to work.

Does anyone have any idea why this is happening?

This may be a bit of a workaround.
Open Kdenlive. Then set the projectsettings you like/want first.
When adding a clip, Kdenlive might suggest to change again to match the imported clip. Now cancel. Repeat adding clips and cancel any suggestions.

I’m not sure this will do you any good but it might be worth a try.

Most of the time I can’t even get that far. Sometimes when I open kdenlive I can get far enough to be able to add a clip, but most of the time it’s frozen the second it’s opened. I’ve given up and changed over to OpenShot. I’ve uninstalled kdenlive.

Hello @josys36
It’s always a shame when someone doesn’t get on with Kdenlive, or more precisely, when Kdenlive doesn’t work for someone.
The amazing thing is that Kdenlive works so stably and reliably with thousands of users.

Switching to another editor is perfectly fine.
But what puzzles me is why Kdenlive has been working perfectly for me on Linux for 4 years, and simply doesn’t work for you, even on different Linux distros. Very strange.
Has the home directory always remained the same?

Sometimes it helps to reset the personal configuration:

Delete: ~/.config/kdenliverc

And if you haven’t given up completely: Tell us about it afterwards.

Kdenlive has never once been stable for me. When I first started using more then a year and a half ago it was fine. Then, it would be updated, and some goofy thing would be broken and I’d have to wait for another update to come out before I could use it again. On and off it’s been problematic. It works, and then it refuses to work.

I actually have deleted the personal configuration now multiple times. It still freezes.

Again I’ve given up. I fight with computers all day at work and I’m getting really tired of fighting with them at home. At this point I’ve switched to something that is working.

I’m glad it’s working for you, but it’s never worked well for me.

Hello @josys36
Well, your switch is understandable, of course. I wish you every success.

Do you have tried with the AppImage (Download - Kdenlive)? If not please do so.
It could be that some packages are missing and you get freeze in Kdenlive.

To rule out hardware: memtest86 overnight would be an idea.

Some apps don’t ‘complain’ if the hardware has a problem, while others can be more sensitive. Occasionally I get kdenlive shutting down on me in the latest version, but thankfully that’s not so common.

I’m done troubleshooting this. Kdenlive has been removed from my system and I’m not trying it again.

It sounds to me like you either have a hardware problem or a system problem, you can’t blame Kdenlive when so many other people are not having this problem. The fact that so many other people are not having this problem with Kdenlive means that the problem is with your computer (hardware or OS), not Kdenlive. Have you tried Kdenlive 24.02.2? Also are you having any problems with other software or just Kdenlive? Have you tried to run any other video editors (Shotcut, Openshot, Flowblade, CinelerraGG, Pitivi) with any success. The current version of kdenlive is 24.02.2 and it is supposed to be very stable, so if you have problems with it, then it is not Kdenlive, it is your system (either your hardware or your OS). Its a shame that you have given up troubleshooting, because now you will never know whether the problem is Kdenlive or your system (hardware or OS).

I can blame Kdenlive when it’s the only software I’m having issues with. Everything else, from my code editors, VMs, Database servers, Web Browsers, OBS Studio you name it I’m having no issues with.

Yes I am using another video editor OpenShot, and I’ve been able to edit a few videos with it without any problems.

The statement that “so many people are not having this issue” is something you cannot prove. I say that because many people will never report an issue, what they will do is move on to something else. So yes Kdenlive works for plenty of people, and indeed worked for me for over a year, but now does not. I didn’t move on right away I posted here, and I keep getting told that I have a problem with my system even though I’m having no other issues. I have other things to get done and I don’t have time for Kdenlive anymore. And, personally I like OpenShot better.

Unfortunately I’m running into the same issue.
Ubuntu 24.10.
Default kdenlive version (24.08.1) as well as latest AppImage (24.12.1).
Freezes almost always immediately after startup - if not, then usually when trying to add a clip.
Deleting the config files didn’t help.

Here’s the log output: pastebin: i06KHnyp

I’m also using OpenShot for now - which works perfectly fine.

Yep, I switched over to KDE Neon some months ago, and I still experience the same problem. I’m still using OpenShot too.

Well so far, Version 24.12.3 is working fine. I just downloaded it yesterday and at this point I’m not getting any freezing issues. Now let’s hope it actually stays that way, but I’m not hopeful.
