What is your operating system?
What is your Shotcut version (see Help > About Shotcut)?
Can you repeat the problem? If so, what are the steps?
I use it in an playlist project to either slow down…
or speed up…
some clips.
In case of slow down the clip is cut off earlier then it should be,
in case of speed up, the clip is at the end and then a gap exists in the project until the next clip starts.
It seems, that the changed duration of a clip resulting by slowing down/speeding up is not considered by Shotcut.
This is currently by design with no plans to change it. Filters are not able to change the playlist, timeline, or clip properties.
You will have your reasons to think like that, but as a user I cannot follow. Whenever I use a speed changing filter, it will have an effect on the duration of that clip.
So how is the filter supposed to be used?
The workaround is to adjust the clip duration by trimming (out point) and using Properties > Duration if needed to extend the maximum for the out point.

The “reason” is only that it is a lot of work and nobody has volunteered their time for free to make it work they way you expect.
This is the advice I have offered in the past. Yes, it is different than other tools. But I do not think it is too cumbersome.
Go to the clip properties and set the duration to something longer that will meet your needs. Maybe just make it way longer than you need. For example, if you are just going to double the speed, then reduce the length by half. But if you are going to use keyframes to make some interesting effects, maybe you don’t know how long it will need to be until you are done.
Apply the Speed filter and adjust the keyframes to your liking
Drag the right edge of the clip to trim it back down to the length …

Totally fine. No offense intended.
Yes, that works for both use cases. It’s just not directly intuitive to use it this way.
Thank you both.
