In my system, blue screen, transparency e transition doesn't works. Blue screen don't cancel the specified color, trasparency and transitions doesn't work. 

Can you help me?

Could I be some library problems?

Same here - kdenlive 0.7.2.1 on Ubuntu 8.10.

I'm coming for that problem too .... I'm not the only one

Same version as you on Xubuntu 8.10

I tried with a blue rectangle in the middle of a clip object instead of my movie. I apply the filter and choose the same color as in my rectangle... and it works...

When I try the same thing with my vidéo clip, it doesn't works :((

Is a blue rectangle in the middle of a clip works for you ? (I think it's this name in english...it's here you can add title, pictures....)

regards

I'm at work....
