Problem description
Problem with Kdenlive effect presets and effect stacks. When I’m saving only single effect as an effect preset - it seems to save keyframe positions as global (i.e. keyframe1 position in the WHOLE sequence). So, obviously, when I’m dragging this preset to the other clip in this sequence which lies ahead or before the original clip I created an effect preset from - it shows 0 or broken keyframes (because they were calculated globally, not locally to the clip itself). However, if I’m creating and “effect stack” preset (just 2 or more effects as a preset) problem vanishes. That’s sounds absurd and either I’m dumb and not getting something or it is clearly a bug with single effect presets, because even adding default Transform effect (which does nothing) fixes the problem. I just don’t want to add “phantom dummy Transform” each time I’m creating an effect, that seems to be dumb.
