Bug ID: 442094
Summary: [ENHANCEMENT] Allow to disable some transform effects
from keyframes
Product: kdenlive
Version: 21.08.0
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: cgir...@free.fr
Target Milestone: ---
ENHANCEMENT SUMMARY
STEPS TO REPRODUCE
1. Import a shaky video to project and timeline
2. add "Transform" Effect, 200% zoom and add keyframes to move video and
deshake it (or use and old kdenlive version with automask effect thanks to
https://ferrolho.github.io/blog/2020-08-09/stabilizing-a-video-subject-in-kdenlive)
3. change your mind for 180% zoom: 2 options 1/ modify each keyframe to move
zoom from 200% to 180% (quite long if you have hudge number of keyframes) 2/
add a new Transform effect to zoom out around 90% (and lose video quality and a
part of your video clip, see https://bugs.kde.org/show_bug.cgi?id=424944)
OBSERVED RESULT
1/ Huge work for kdenlive user.
2/ or Missing part of video.
EXPECTED RESULT
Transform effect combines 4 sub-effects: Move, Zoom, Rotate and opacity.
Allow kdenlive user to enable/disable keyframes action for each sub-effect.
When keyframes applies to sub-effect: as actually.
When keyframes does not apply to sub-effect: sub-effect parameters can be
modified, but applies to the whole effect, as if no keyframe present.
SOFTWARE/OS VERSIONS
Linux: Ubuntu Studio 20.04.3 LTS
kdenlive-21.08.0a-x86_64.appimage
ADDITIONAL INFORMATION
Of course, it would be better to be able to set different keyframes for each
sub-effect... but it solves with multiple Transform effects on same clip... oh,
no, because of effect pipelining in project video setting that clips off some
video parts, see https://bugs.kde.org/show_bug.cgi?id=424944)
