Something is wrong with changing the speed of a clip. no matter to what speed i set it(50%, 500%, 10% does not make a difference) and no matter how long the clip is(seconds, hours, makes no difference), it shrinks/grows to about 2 seconds after changing the speed of the clip from 100%. The durance does not even change when changing the speed back to 100% after changing it once, the clip is messed up until undoing it. Deleting the effect does not change the clip back to its default length. This clearly is wrong behaviour.
I tried this again. It seems to work on movie clips but always fails on slideshow-clips. How to fix it?

Am i the only one having this error or everybody else is not using this effect on slideshow-clips? Really would like to get this working.
Slide-Show clips are pictures like title clips. Speed changes have no influence. Make the slide-show clip longer/shorter to change the duration.
This was an issue for me. Version 20.04.0 on Windows 10. I wanted to reverse the slideshow clip so it would play backward. Reversing or changing the speed of slideshow clips does not work properly. The workaround was to render the slideshow clip as an mp4 and import the mp4 video clip. Change speed and reversing works on mp4 clips but not slideshow clips.
to anyone still having this bug; check the properties of your clip. For some reason OBS output gave me a clip that showed as 1000 FPS in kdenlive. Apparently kdenlive can't deal with changing the speed of clips with a strange FPS as low as 15 or a high number. render your clip as a selected zone first, then import the output clip and change the speed of that instead. A FFMPEG re-render with the right parameters also works.
Thank you for the tip. I added your solution here: https://invent.kde.org/multimedia/kdenlive/-/issues/727
This seems like a simple bug to fix (in the slideshow clip import). It's quite easy if you know how, to rename all the frames or make them into a video with ffmpeg, but why? The whole idea of kdenlive is that it's an accessible UI for making movies. I would have thought it was quite common for people to render frames for half of an animation (using Blender for instance) then make the second half a reverse of the first. Developers, you have to assume that 99/100 people with this problem won't tell you. They will jut find an alternative to kdenlive!

I think I fixed the speed change now, but for some reasons the render output seems to be right if you reverse a clip, but the preview in the project monitor not.
