add a color clip to a new project and change the length to be eg. 10 frames. When you add the clip to the timeline, it reaches from 00:00:00:00 to 00:00:00:09 (10 frames), but the project has one frame more (00:00:00:10), so when you play it back or render the full project, you get one extra black frame at the end.
Created attachment 102592 [details] patch to fix project length I tried to fix the bug myself by adjusting Render::mltCheckLength to set the "out" time to "duration - 1", which should be correct, if the first frame is "0". With the patch, the problem is solved for me, I am not sure though if there are other points in the code where this also needs to be changed.
Git commit 9869d0b0cd75958cf2de3b53a57d578887dd7ba2 by Jean-Baptiste Mardelle. Committed on 04/12/2016 at 16:37. Pushed by mardelle into branch 'Applications/16.12'. Fix black frame at end when rendering full project M +3 -4 src/dialogs/renderwidget.cpp M +9 -12 src/mainwindow.cpp https://commits.kde.org/kdenlive/9869d0b0cd75958cf2de3b53a57d578887dd7ba2
I can confirm that after the fix, the rendering output no longer has an additional black frame at the end. In the interface however the project still has that frame, but I assume that is intentional.
Thanks for your confirmation. And yes, the last black frame in UI is intentional, it is necessary to allow some editing features.
Kdenlive 16.12.3: problem still present, but last frame is not black, but with same color than clip color. Exporting full project or exporting selected zone makes same extra frame.
Created attachment 107598 [details] Extra black frame at the end of the project Hello Attached simple blckframe.kdenlive project file that has that extra frame at the end after the last clip. Removing the last clip, the extra frame does not disappear but is still there after the new last clip. kdenlive 17.08, opensuse leap 42.3 amd64
Can you please update to the latest version (20.12.3 at the moment, https://kdenlive.org/en/download/) and report here whether this is still happening? If this persists please check if it is might related to this bug 425960 especially this comment: https://bugs.kde.org/show_bug.cgi?id=425960#c10
