Description Roxane 2020-07-06 19:13:17 UTC 
Created attachment 129944 [details]
just showing the difference between the bow and the cut

When I added a rotoscoping effect and zoomed in twice on the monitor to be more precise, the red line didn't match the effect


STEPS TO REPRODUCE
1. put clip on timeline (in my case title clip)
2. drag and drop rotoscoping on it
3. zoom in on the monitor using the overlay on the top right, clicking twice
4. draw around a letter

OBSERVED RESULT
the red box doesn't match the part that is cut. It czn be solved by zooming out and back in.

EXPECTED RESULT
having the box matching the cut part

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian with the Appimage

Me again, it is still buggy, if i first apply roto, then select the clip to see the yellow message saying to add points, then zoom in the monitor, it works fine. If i'm zoomed in, then add roto and start adding points, there's a problem.

Putting into https://invent.kde.org/multimedia/kdenlive/-/issues/967

Still happening in Master.
Comment 7 Julius Künzel 2021-10-05 18:20:04 UTC 
This seems to be fixed (@farid and me test and we can't reproduce anymore). It was probably solve with https://invent.kde.org/multimedia/kdenlive/-/commit/0a80687f392d30a7dd5bb15cfad63fad5a7f0c12

Please reopen if this is still happening with the last stable version
