In Kdenlive version 24.12.2, I cannot save custom version of "motion tracker" effect. When I try to use that saved filter and click "Analyse to Apply Effect" I keep getting an error that reads "Cannot create filter ***". What could be wrong. If I save "motion tracker" effect with a saved preset that preset works. STEPS TO REPRODUCE 1. Put Motion Tracker effect on clip 2. Change settings in effects stack 3. Click icon on Motion tracker bar to drop down "Save effect" 4. Save effect with new name 5. Start a new project and use the new saved effect on new clip 6. Click on "Analyse to Apply Effect" OBSERVED RESULT 1. Get error message that reads "Cannot create filter ***". 2. Cannot use the saved filter EXPECTED RESULT 1. Should work the same as Motion Tracker effect with changes saved with new name. SOFTWARE/OS VERSIONS Kdenlive 24.12.2 flatpak version/Linux Mint 22.1 ADDITIONAL INFORMATION
Here's debug info Kdenlive: 24.12.2 Package Type: Flatpak MLT: 7.30.0 Qt: 6.8.2 (built against 6.8.2 x86_64-little_endian-lp64) Frameworks: 6.11.0 System: KDE Flatpak runtime Kernel: linux 6.8.0-55-generic CPU: x86_64 Windowing System: xcb GPU: Movit (GPU): disabled Track Compositing: qtblend
Forgot to mention that if I use multiple uses (4) of "Motion Tracker" with Blur type "Gaussian" on a single clip and then split the clip into multiple clips, then render all clips, the result doesn't have the Motion Trackers with blur on them. I use the Motion Tracker with Blur to blur out static areas in different clips, not with tracking keyframes. I've used Kdenlive with this method for 5 years and no problem. Just started last week. Kdenlive must have updated through my Linux Mint Update Manager from earlier Flatpak version.
Thanks for your report, I am working on a fix

Just tried out saving this effect in nightly build 25.07.70. Motion Tracker does save with new name and that effect is usable, however it doesn't render out to a finished clip. Just thought I'd pass this trial on. I maybe jumping ahead to early. Noticed you said fixed in 25.04.0.

Thanks for testing. It works for me, that might be another bug. Can you give me more details: * Where did you apply the effect: on a project bin clip, timeline clip, track ? * what parameters did you use for the filter ? Can you maybe attach the saved effect in this bug report ? It is in : $HOME/.local/share/kdenlive/effects and called your-effect-name.xml
Its rendering now with the effects. However when I first place the effect on the clip, a red x appears as I move the blur rectangle into position. Then when I play the clip the blur rectangle moves along the line back to the x. Before the rectangle would remain static unless I Analyed to Apple Effect if I used the effect to follow motion. I just want to use it to blur still areas. I could do this in previous Kdenlive versions. I've attached screenshots.

I decided to start fresh with 24.12.3. The Motion Tracker effect wouldn't work as a static blur but would work as motion tracking by analysing for keyframes and would render. I did manage to get it to use a saved static blur effect by adding a copy of the first keyframe to the end of the clip. That got the blur to stabilize in place and was able to render. Also I could use multiple instances of saved blur effect each with added copy of its first keyframe added to end of clip. Also tried to split clips to see if each effect would remain in place and they did. Would be nice if just adding the motion tracker and adding blur would remain in place and render with just the first keyframe after placement. This is how it use to function for me. Appeciate your work on such an amazing piece of software. Hope this bug gets added
I apologize for another comment. I am amending previous comment. I can use multiple instances of Blur Tracker (saved Motion tracker with changes) on clip in the Timeline then move each instance of Blur Tracker rectangle on project monitor window into different places (static). When I've done that I then go to end of clip in the Timeline and in the Effects Stack I add a keyframe in each instance of Blur Tracker. That holds each instance in place and also can Render. I am also sending new Blur Tracker xml as attachment and desktop pic.
