Bug ID: 442631
Summary: motion tracker: re-analysis after reset does nothing
Product: kdenlive
Version: 21.08.1
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
In Motion Tracker effect, only the first analysis works: the progress bar
fills, then the "tracking data" button and link appear. But after that, when I
want to change a parameter (algo, spacing) and redo another analysis, almost
nothing happens: I can see the bar filling much quicker, but the "tracking
data" button does not re-appear.
STEPS TO REPRODUCE
1. Add a Motion Tracker effect to a video clip
2. Click Analyze
3. Click Reset
4. Click Analyze again
OBSERVED RESULT
The Tracking data button and link do not appear. They show only the first time,
before reset.
EXPECTED RESULT
I should be able to do any number of analysis, with different parameters
(tracker algorithm and keyframe spacing).
SOFTWARE/OS VERSIONS
Windows: not tested, but I will
macOS: cannot test
Linux/KDE Plasma: debian stable
(available in About System)
KDE Plasma Version:
KDE Frameworks Version:
Qt Version:
ADDITIONAL INFORMATION
As a work-around, I just have to restart Kdenlive to be able to do another
analysis. I tried to remove the Motion Tracker effect, then to add it again but
it does not seem to always solve the problem. I suspect some cache to remain,
blocking next analysis.
