Description John Smith 2021-06-20 17:38:02 UTC

SUMMARY
Wrong duration is set when adding a transition.

STEPS TO REPRODUCE
1. Go to "Settings -> Configure Kdenlive -> Misc" and enter "00:00:01:00" into the "Transitions" field. Apply.
2. Add 2 clips to project bin then into the timeline, the first on track 1, the second on track 2.
3. Add a transition (i.e. Dissolve) between them.

OBSERVED RESULT
After hovering the cursor at the added transition box, the duration shown at the bottom bar is "00:00:00:29"

EXPECTED RESULT
The duration shall be "00:00:01:00" as set in the defaults.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.81.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION
Project settings: 1520p 29.97FPS

HD 1080p 29.97 fps - Kdenlive

I think the problem is that Kdenlive recognize the clip wrong. If I put a clip with 29.97 into project bin Kdenlive will switch the project to 29fps – which is wrong. Can you confirm this behavior when you put the clip in a new project?

Transcoding

I'm using transcoded clips, which are converted from 29.97 to 30 fps.
