Hello. I'm pretty new here so idk where this question would go, but I've run into a problem with rendering videos since I updated Kdenlive this morning. I've actually had Kdenlive since July of last year but started using it in October and it's been working really well. I would render videos without a problem until now. I've never actually updated Kdenlive since I installed it but I updated the editor this morning and now I'm running into errors when I render a video (everything else is working perfectly fine except for rendering):

[swscaler @ 000000000bd84040] Warning: data is not aligned! This can lead to a speed loss Current Frame: 33, percentage: 0
[mp4 @ 0000000008be7a40] 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 @ 0000000008be7a40] Encoder did not produce proper pts, making some up. [mp4 @ 0000000008be7a40] Application provided invalid, non monotonically increasing dts to muxer in stream 1: 16055296 >= 16055296

I'm not particularly knowledgeable when it comes to stuff like this. Does anybody know what this is or how I can fix this? Thanks.

is this video coming from an OLD project? or do you have made it from scratch using latest version of Kdenlive?

can you tri latest appimage? (there was a lot of fixes) : https://binary-factory.kde.org/job/Kden ... 4.appimage

Yeah. The project itself was made like one month ago, but it was made with the same version of Kdenlive I've had since July. It was able to save fine, but the rendering became a problem when I updated the editor yesterday.

I'll try what you suggested, but the link you gave seems to be invalid.

Oh sorry. I never specified I'm using a windows computer.

OK.. Windows.. a very massive BUG was fixed (and the fix will be release on nxt 22.04) https://invent.kde.org/multimedia/kdenl ... ssues/1273
related to clips the are made using smartphones...
this is an updated build (with the fix) for Windows ( but i think that : if the clips have a multiple frame rates.. the project need to be recreated...)
