I was editing my video, using Kdenlive yesterday, when it suddenly crashed. Since then, I'm unable to reopen my file. I can open other files with no problems, but whenever I try to open this file, Kdenlive crashes.

I had this problem with Debian Stable (Stretch), and today I've updated to Debian Testing to see if it was a bug that could be solved with a newer version.

I tried both with the repository app as with the AppImage version.

The kdenlive.log file shows as follows:

Code: Select all

When I run it from command line, I get as follows:

Any ideas? Please help, I can't lose this project. Thanks!

You should run Kdenlive on a stable platform only. My suggestion:
- Use AppImage 18.08.3. Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage.
- Try the following page https://thediveo.github.io/kdenlive-pro ... lyzer.html (more info here: https://github.com/TheDiveO/kdenlive-project-analyzer) to try to repair the kdenlive file.

Thanks for your response!

I've tried the AppImage you've sugested. It was in fact the same I've been trying before. Same results.

This is the output I get when I run the AppImage:

Code: Select all

I've analyzed my project on the link you've sugested and got some warnings:

Video 3 missing video compositor

How do I repair the file?

I've managed to repair the transitions' errors. Now the only warnings are the following:

Warning: not enough internally-added audio mix transitions found; there are more tracks (7) than audio mixers (5) in project – this project need its internally added mix transitions rebuilt, as audio mixing is currently incorrect.

This I have no idea how to fix, I appreciate any suggestions.

You can try: Restart your system (switch off, switch on). Then update Linux. There are some parts missing.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

You have worked with GPU switched on (MOVIT). Please switch off GPU acceleration as Movit is not stable. Try to get Kdenlive running as AppImage. Maybe Kdenlive can recover the file. Anyway: make a copy of your Kdenlive-file before you do any test. If Kdenlive cannot load the file I’m a bit lost. I saw on the Bugtracker someone who had a similar problem.

Hi Merlimau!

Thanks for answering. The system is already up-to-date. What packages do you think are missing? So I can look for them.

GPU processing is not only disabled, it is greyed out, I cannot even activate it.

I’m not a Linux specialist. Found 2 similar issues with Wayland: viewtopic.php?f=215&t=153901&p=404217#p404217 solved with nVidia driver and https://github.com/flathub/org.kde.kdenlive/issues/18 solved with a terminal start-up.

The file problem seems that you have a 7 channel audio on the track selected but only 5 channels on the audio itselve (or vice versa).

I've solved it!
I've edited the .kdenlive file and found this:

Code: Select all

<tractor id="maintractor" title="Anonymous Submission" global_feed="1" out="7525" in="0">
  <track producer="black_track"/>
  <track producer="playlist1" hide="video"/>
  <track producer="playlist2" hide="video"/>
  <track producer="playlist0"/>
  <track producer="playlist3"/>
  <track producer="playlist4" hide="audio"/>
  <track producer="overlay_track" hide="audio"/>

So I thought this might refer to the 7 channels to only five mixers. So I removed the last line:

<track producer="overlay_track" hide="audio"/>

And that did the trick!



Thanks for the help!

Glad to hear.
Do you get Kednlive on Debian running?
If all is OK please mark as solved.

For some reason now the title clips in the timeline do not have transparent background, covering the video in the background in black. If I open the editor an choose "Show background" the image behind appears, but not in the timeline.

Maybe this has something to do with the track I deleted?

If I apply the "dissolve" filter, the video shows in the background, but then I get the "fade" effect, which I don't want.

If I add the "screen" transition (which I don't know what it does), it works.

:/

But before this whole crashing and editing the .kdenlive issue it was working without this weird workaround.

Here is a similar issue: posting.php?mode=reply&f=270&t=155934

It's not really the same issue. The title for me appears in the project monitor. The problem is with the background, that is always black, not showing the video on the track below it, even with the oppacity in zero. The oppacity appears though if I add any transition effect, so I'm using that as a workaround.

I didn't have this issue before I deleted that line from the .kdenlive file.
