I want the first track to display with some transparency over the second trac, so i set 2 tracks, put the transparency effect on the first one.. nothing happens (changing transparency settings doesn't change anything). Is it a bug or am I missing something?

Same problem here. Blue screen not working.
It worked before(in 0.6...versions) And there was some transition, that provided same effect, but now nothing works.
I had to make all my transparency in blender, with nodes,and a lot of pain,because it's not a video editor.

Now Kdenlive looks beautiful, but still it is almost useless.

Here is a workaround to get the blue screen effect working like in previous Kdenlive versions (please note that this effect is far from perfect and produces rather pixelated results around the edge...):

• Put background clip on track 2.


• Put overlay clip on track 1.


• Add Blue Screen effect to overlay clip.


• Add composite transition to overlay clip.


• Adjust Blue screen effect parameters (color & variance).

thanx for the tip for the bluescreen.

As the transparency effect became.. transparent.. in the last svn, i did it with the composite transition, it's a bit odd to tweak the size of the video you want transparent but it does the job.
