[Kdenlive-devel] [PATCH] exports.profile: DV and DVD improvements

[Dan Dennedy]

I added support for ildct=1 and ilme=1 to mlt, so I added them to the DVD 
export profiles. I think the raw DV profiles should use avformat, not libdv, 
for better quality. Note that ffmpeg dv codec understands the ildct option 
that might improve quality in certain conditions. ffmpeg also supports a DV 
variant called DVCPRO50, for which I added export profiles.

I did not look that closely yet at other export profiles, but I see some 
properties not yet supported by MLT. I am thinking about using ffmpeg's new 
option parsing to make properties equivalent to the the ffmpeg command line 
options.
