Yes, I would also like to see this working with my brand new RH8.0, which only 
features 3.0.5.

... compiling ... oh.. ah.. everything builds/runs even on RH7.2, 
... great. ;-)


done:
 write raw DV:    finished
 write mpeg1:     experimental (optional at ./configure --with-ffmpeg)
                  I need help with ffmpeg to support all kinds of
                  format. This is _not_ "if one works, all work".
 sound:           OSS, anybody knows how to use aRts?

todo:
 play:            will play video as fast as possible 
                    -> slow down when too fast
                    -> reduce quality when too slow
 commun:          update to lates VEML in last kdenlive version


Since I use YUV colorspace to display the video, all effects are basically 
broken because they work in RGB space. (You can of cource force PIAVE to use 
RGB space, but then wou'll have sluggish playback)

There are two options:
a) short term fix:   use RGB when effects are applied, use YUV otherwise
                     this needs a little work on the display and other details
b) long term fix:    reimplement all effects in YUV space
                     YUV images are smaller and thus will render effects 
                     faster. This will take a lot of work, but is the way to 
                     go. (Only text overlay will not gain much)

If kdenlive will feature effects soon, I would go for option a) then slowly 
move to b).   If we won't get effects soon anyway, I would skip a) and start 
directly with b).   Are there any opinions?


Cheers,
Rolf
