When doing fine adjustments on the speed effect with the scroll wheel, after a short while kdenlive segfaults. I also notice significant memory usage, almost the same as the Pan & Zoom effect had some time ago. Reproducible: Always Steps to Reproduce: 1.Load a longish clip on the timeline 2.Add speed effect 3.adust speed with scroll wheel of mouse. I spent a few seconds adjusting the speed up, to get a shorter clip. The error seems to pop up when getting to large amounts of speed-up Actual Results: Kdenlive segfaults Expected Results: Unlimited speed-up or down.

I cannot confirm this in recent git version of Kdenlive. At least not with my 5:57 test video: https://archive.org/download/StockVideoGameVideo/TriggerRallyGeneralPurposeVideo.mp4 Should the link not work, it's the "MPEG4" download from https://archive.org/details/StockVideoGameVideo I demonstrate this inability to reproduce this error message/crash in a video: https://youtu.be/bZUAowpFyTI How long was your video? Can you reproduce this issue using the video I used?
Hi there. kdenlive is certainly more difficult to crash now. My video clips are 4K, and 3.7Gb each. When just zooming through the clip, the memory used by kdenlive slowly increases, and before long my system runs out of memory, and then kdenlive crashes. -Evert-
Evert, is this bug still relevant? Or has it been fixed? We would like to reduce the bug report backlog... ;)
I am unable to make kdenlive crash now with this effect.
