Description Roxane 2024-09-03 08:59:46 UTC

SUMMARY
Hello ! There's an issue with preview rendering when clips are sped up or slowed down with "change speed" (or ctrl + slide end). The clip's speed isn't changed in the preview render. It still works with a normal render.

STEPS TO REPRODUCE
1. To easily see : cut clip in 2, speed up the first part, move the 2nd part to touch the first. Everything should still be smooth
2. preview render the part of the timeline

OBSERVED RESULT
The first clip isn't sped up, there's a definite cut between both clips

EXPECTED RESULT
first clip should be sped up

Thanks for your report. I could not reproduce. Can you check against the 24.08.0 release if you can still reproduce?
Can you reproduce the problem 100% of the time?

On 24.05.2 I can't reproduce 100% of the time. I had two examples when i posted this, and I tried twice more, and one is working and one isn't. I'm not sure what the common denominator is though.

Just installed 24.08.0 : seems to work for now, i haven't investigated much
