I use Gnome and have installed all the updates.
I created a video with Kdenlive 21 to which I applied a zoom effect with keyframes.
In the preview I see the zoom correctly but after video export the zoom does not appear.
I downgraded to Kdenlive 20 but got the same error.
I have made several test videos and there is always the same problem
I used keyframe zoom with Gnome 40 without problems a few weeks ago.
If I download the appimage version of kdenlive 21 the same video is exported correctly.
