STEPS TO REPRODUCE
1. Add a random video to the timeline (I used .mkv).
2. Add a random Title Clip to the timeline with typewriter effect on (I used "Testing, testing...").
3. Render the video (I rendered to .mp4).

OBSERVED RESULT
Render crashed. 
[mp4 @ 000001fa7fcded00] 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 @ 000001fa7fcded00] Encoder did not produce proper pts, making some up.

EXPECTED RESULT
Render finished.

Can you still reproduce this problem with 25.04.1?

And did you really not get a working video at the end of the render,
or did you just see this warning (which does sometimes trigger spuriously)?

If you didn't get a correctly rendered video, could you please attach a minimal project file
and precise steps to induce the crash.  Ideally a project file that doesn't need any external
resources (eg. uses colour clips instead of an external video file) if it's possible to reproduce
it that way.
