Summary

0003014: Colours get a green tint when a title page is composited

Description

When I composite a title on top of a clip, the colours get a green tint. This is particularly bad when a (mostly transparent) title fades out, and the colours suddenly jump.

The problem is visible both in the preview window, and in the rendered video.

Steps To Reproduce

Example project: http://the.earth.li/~igloo/kdenlive_colour/colour.kdenlive [^]
Using example (6.2MB) clip: http://the.earth.li/~igloo/kdenlive_colour/00148.MTS [^]
Result of rendering (3.0MB): http://the.earth.li/~igloo/kdenlive_colour/colour.mpg [^]

Additional Information

$ kdenlive --version
Qt: 4.8.2
KDE Development Platform: 4.8.3 (4.8.3)
Kdenlive: 0.9.2

I think it uses this melt:
$ melt --version
libdc1394 error: Failed to initialize libdc1394
melt 0.8.0

BTW ver 0.9.2 is not supported any more. You should upgrade to 0,9,4 - and you will get affine transitions on titles by default.
