Comment 2 Dany 2017-02-05 23:04:09 UTC

Thanks for reply, but I have no idea what I have to do.
I read your link and code but is Ostrogoth... :(

Comment 3 Jean-Baptiste Mardelle 2017-02-05 23:09:47 UTC

Yes, I guess some comment is welcome... First, thanks for your report. I have fixed the bug  in git (the source code repository).

The fix will be in Kdenlive 16.12.2 that will be released next week. So whenever you upgrade Kdenlive, the bug should be solved.

Comment 4 Dany 2017-02-05 23:18:03 UTC

Well. Great work!
Very FIRST, excuse me (I'm very poor in Linux knowledge and its around world (and english language too!!!))

Second, thanks to YOU (and your TEAM) about your Kdenlive work!:)
