So I've recently tried to render my project in mp4 but i get this kind of crush during render:
[mp3 @ 00000179ae43d400] Estimating duration from bitrate, this may be inaccurate
[mp3 @ 00000179ae6bbd80] Estimating duration from bitrate, this may be inaccurate.
How can I fix it? I have kdenlvie 22.08.03, win 10.

try to use latest installer and maybe share your project (without clips)
