Error rendered, incomprehensible

Help

Hello everyone, I face a concern when I want to render a sequence of my project. I have this error message:

Le rendu de /home/pympc/Vidéos/Vietnam 2024 -Jr12.mp4 a été interrompu par une erreur fatale

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x5e88d5eaa2c0] st: 0 edit list: 1 Missing key frame while searching for timestamp: 3003 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x5e88d5eaa2c0] st: 0 edit list 1 Cannot find an index entry before timestamp: 3003.

[mp4 @ 0x711234201040] Timestamps are unset in a packet for stream 1. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly [mp4 @ 0x711234201040] Encoder did not produce proper pts, making some up.

What is it talking about ???
Despite the automatic translation (I’m not talking about English) I don’t understand. If 3003 corresponds to the position of the Time-Line, nothing shocks me on it.
So what else.
Thank you to those who will be able to enlighten me on this subject

As far as I can tell, these are warning messages, and chances are high that a file still was produced.

Did you get a message about transcoding into edit-friendly format when loading the source(s)?

Thank you for this answer
In fact, it is a mixing photos and video sequences. I did not have the slightest message when it comes to importing these elements into the project.
I have the impression that this situation arrived after a trip of clips …
In addition I realize that all of my sequences are now concerned since I have the same error messages during the request for rendering …
I had already had rendering problems with other old version of Kdenlive and I “resolved” by copying time-lines from one kdenlive to another. But there, impossible, I always have an error message, staring that there were not enough tracks (which is not correct). Sad!

After an update of Manjaro Gnome Linux including Kdenlive in version 24.12.2, things do not manage.
Lots of error when loading my file.

By checking the timeline, I realize that the transitions are offset as here

In short, a hell of a bazaar. I have the impression that I will lose hours of work
:disappointed_relieved:
Without understanding much about what’s going on.

My french is pretty thin, but that doesn’t look directly related to the initial warnings you posted …

I’d suggest two things though.

  • The ever green “Use the Appimage”. Really. A very disproportionate number of the problems we see people having here are specific to their distro packages.

  • If you look in ~/.local/share/kdenlive/.backup you’ll find checkpointed versions from every time you saved your project. You might be able to back up to one of those from a point before the issue you’re seeing now.

Thank you Ron,
Me is English like many French people elsewhere.
If the translation is good, you advise me the appeter. So I installed the adpiring of Kdenlive and … Everything is ok.
A great relief.
Only small concerns is that I have a mounting wheel that I must reprogram.
Thank you again
