Bug ID: 412039
Summary: Auto mask is several kinds of horribly broken
Product: kdenlive
Version: 19.08.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: darxus-...@chaosreigns.com
Target Milestone: ---
SUMMARY
I'm trying to use it to obscure a license plate in a video, using
kdenlive-19.08.1-x86_64.appimage on ubuntu. The red rectangle that's supposed
to surround the obscured area often doesn't - it's around some other random
spot on the video. Several times parts of the video I've already done have
become unaligned, and I've had to do them over again. I just tried to add a
second auto mask to a section of the video, and dragging that one around caused
the other one to move to a randomly different position. It has crashed on me a
couple times. I'll go to the beginning of a clip, click auto mask's analyze,
it won't get the alignment quite right, I'll do exactly the same thing again,
and it'll get it right. I don't know for certain that that part's a bug, but
if that randomness is intentional it would surprise me.
The motion tracking is pretty disappointing. I wonder if that could be related
to the misalignment of the red box with the obscured area - maybe it's doing
tracking based on the position of the red box?
(Not really related, but I'd much rather have a single solid color than
pixelation, since with enough frames, pixelation can be reversed.)
STEPS TO REPRODUCE
1. Try to use auto mask
OBSERVED RESULT
Sadness.
It's tough to tell what of the console output might be useful from my last
crash, but here's the end of it:
