--- Comment #1 from Ashark <ash...@linuxcomp.ru> --- I have tested mlt for supporting transparency in these codecs. I used the following command: melt normal_video.mp4 -track <file> -transition affine where <file> is a png or video file with transparency. Result is the same as for ffmpeg. Here is a table of results: +-----------------+--------+-----+----------+ | container-codec | ffmpeg | mlt | kdenlive | +-----------------+--------+-----+----------+ | png-none | yes | yes | yes | +-----------------+--------+-----+----------+ | qt-animation | yes | yes | yes | +-----------------+--------+-----+----------+ | avi-tscc | no | no | no | +-----------------+--------+-----+----------+ | qt-prores | yes | yes | no | +-----------------+--------+-----+----------+ | qt-cineform | yes | yes | no | +-----------------+--------+-----+----------+ So I can say that the fact that kdenlive is not supporting qt-prores and qt-cineform is definitely a bug. And tscc is probably ffmpeg's unimplemented feature. -- You are receiving this mail because: You are watching all bug changes.
