I use Kdenlive 0.9.2 on Debian testing 64bits.
When I want to import .mov video in my project, Kdenlive tell me « Clip is missing and will be erased from the project». These .mov file exist and works on VLC. This issue happen only with video importation, while playing sounds and photos works.
I runned Kdenlive from a terminal and I get this output : http://pastebin.com/JbjW6fgv
