yes yes, I'm sure I can make piave as fast as kino, actually I see a lot of 
possible improvements in kino src ;-)

Right now all the stuff (filters and display) is based on RGB. This is very 
easy and butt slow. Most sources (DV, MPEG, etc. ) are in YUV, most targets 
as well. Only RGB target is the screen, and most people have decent graphics 
cards whic can do YUV->RGB in hardware. Sooner or later I'll move all the 
algorithms to YUV. That will impove speed a lot, but will need some work.

BTW. yesterday, I managed to read DV and to export a complete scene with 
effects etc. to MPEG1 !  ( It looks crappy though ;-(  )
