[Kdenlive-devel] Losless rendering profiles in Kdenlive: dirac, ffv1 and huffyuv

[Jean-Michel Pouré]

Dear Friends,

I added dirac, ffv1 and huffyuv to Kdenlive SVN export profiles.
Sound is provided by flac encoding in dirac and ffv1 cases.

Checkout Kdenlive svn.

These profiles are meant for achiving source media, not for playing.

* dirac does not work well and is very slow. This may be due to the
difference in implementation between libschroedinger and ffmpeg.

* ffv1 plays very well and is lightning fast. I encourage you to test
it. It can even play in Kdenlive very well. Vlc 0.9.4 can play it too,
except for sound.

This is the first ever complete non-destructive format working with
compression.

* huffyuv is a standard compliant raw codec, fully tested.

Of course, in dirac, ffv1 cases, you will need to compile ffmpeg with
the required options. Marillat ffmpeg includes the necessary stuff by
default in Debian.

Happy testing.
Kind regards,
Jean-Michel
