Bug ID: 361773
Summary: Kdenlive freeze - edit external altered project
Product: kdenlive
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: ovidiu....@gmail.com
I edited a project file (in Kate) to replace one video clip with a copy (see
why at the bottom).
After opening the project in Kdenlive, I played through the timeline and it was
ok. I tried to increse the speed effect of one clip section and then Kdenlive
froze.
I replaced in the project file (via Kate) all occurrences of
"VID_20160402_114623.mp4" with "output.mp4". I'm aware that this is not normal
and you shouldn't do this, but since the file is a copy, I expected this to
work. Anyway, Kdenlive should not freeze and it should complain that the
project is invalid, if it actually is.
Why I did this:
I used OpenCamera to make the recoding in landscape mode. The exif of one of
the videos showed the resolution as landscape (1280x720) but the Rotation got
set to 90 for some reason.
This wasn't a problem until a recent update when video players (including
Kdenlive) started reading this Rotation flag, and rotating the clip everywhere.
Research on the problem eventually got me here:
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=6670.0 and then here:
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=6010.0
So I copied the clip with ffmpeg `ffmpeg -i VID_20160402_114623.mp4 -c copy
-metadata:s:v:0 rotate=0 output.mp4` in order to rewrite the rotation flag.
I had already don lot's of splitting and effect adding to the project on the
original clip (which wasn't rotated until some time ago). It was too much work
to be repeated. Since it's basically a copy, renaming the file in the project
file should have worked fine.
Reproducible: Always
