Description Cyril Giraud 2020-08-22 17:03:58 UTC 
SUMMARY
When a Rotate effect is set with 2 linear keyframe, hasardous rotation is set after last keyframe.


STEPS TO REPRODUCE
1. Create a new empty project, with 1 color clip moved to timeline.
2. Add a Rotate effect. Keep 1st keyframe to 0 X rotation and add a 2nd keyframe somewhere with 300 X rotation.
3. Look at rotate effect along the color clip (between 2 keyframes, and after last one).

OBSERVED RESULT
o1: Rotation is correct between keyframes.
o2: Rotation is still moving after last keyframe.


EXPECTED RESULT
r2: Rotation should be static after last keyframe.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu Studio 20.04 + kdenlive stable PPA 20.08.0.
MLT version 6.23.0
KDE Frameworks 5.71.0
Qt 5.14.1 (construit sur 5.14.1)
Le système de fenêtres xcb

Same problem with kdenlive-20.08.0-x86_64.appimage

ADDITIONAL INFORMATION
Workaround: set a 3rd keyframe at end of clip with same rotation parameters than 2nd one.
