***


STEPS TO REPRODUCE
1. Make a simple project
2. Start the rendering and it's stopped around 95%.

OBSERVED RESULT
The rentering is stopped all time around 95%. My video can't be played.

EXPECTED RESULT
The completely rendering of all my differents projects

SOFTWARE/OS VERSIONS
Windows: 11
KDE Framework: 5.94.0
Qt: 5.15.2 (built against 5.15.2)
MLT: 7.7.0

ADDITIONAL INFORMATION
I just make an update of KDE, before I had KDE: 21.08.0 and MLT: 7.1.0. With this version I haven't problem to render a project in my PC.

The log of the rendering : 
[mp3float @ 000001b009a2b800] Could not update timestamps for skipped samples. Current Frame: 1, percentage: 0
[mp4 @ 000001b001f74b80] 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 @ 000001b001f74b80] Encoder did not produce proper pts, making some up.

Which Windows build (or download) are you using? Would you be willing to share your project and media files with me so I can try reproducing it?

I use the 21H2 Version of Windows 11 (build of operating system 22000.739)

You can find my project with this link :

I tried with the standalone Windows 22.04.2 and 22.04.3 builds from kdenlive.org and was not able to reproduce this issue on Windows 10, unfortunately.  The video rendered successfully in both cases. (I don't have Windows 11 handy to test with.)

Some things you could try to see if they make any difference:

* Does rendering to a different container type or codec make any difference?
* Do you have enough hard drive space for the output?
* Since your rendering stops at 95%, what happens if you remove the last 5-10% of the clips? Is there a particular clip that causes this problem?

I have test with differents codecs and qualities and it's the same problem.
The available space is 10 more than the project.
I removed the last 2 clips and the rendering stopped at 4s of the end. I retried without the last 30s of my project and it's the same thing. The rendering stopped at 4s of the end. I think it isn't the video because I have the same problem and that with my differents projects with this new version of KDE.

I remade my project with the 21.08.0 version of KDE and I was able to finish my rendering with it.

Thank you for reporting. We made some rendering fixes. Please try with version 22.12.0. Make sure parallel processing is switched off in: render -> more options.
Comment 6 quentin.boinot86 2022-12-18 11:32:16 UTC
Hello,
I haven't the problem since I have reinstall windows on my PC. I think it was a driver problem or things like that.
Thanks
