See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

The render output is not smooth. I have resorted to using other programs but would like to keep using Kdenlive if this was fixed.

STEPS TO REPRODUCE
1. Open a fresh project. Reset Kdenlive settings from help menu.
2. Drag in a Zoom recording (640x360 25fps)
3. Kdenlive asks to change the profile to 640x360 25fps. Accept that change.
4. Make a cut in the video and delete part of the video.
5. Render it to mp4 with all the default settings.

OBSERVED RESULT
The rendered video is stuttery and choppy. 

EXPECTED RESULT
A properly rendered video.

SOFTWARE/OS VERSIONS
Fedora 35 using x11 and not Wayland.

ADDITIONAL INFORMATION
Hardware is a Lenovo P1 gen 4
Core i7 11800H
32GB RAM
Nvidia T2000

Do you have used the official Kdenlive flatpak from flathub https://flathub.org/apps/org.kde.kdenlive? If not please install Kdenlive from flathub and try again.
