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 for me with kdenlive 0.7.1 on Ubuntu 8.10 64bit
(there's also othe effect that doesn't work like luma and chroma)
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.
