The wipe transition causes a green tint to appear. The attached example uses 9 wipes at the same time, between plain white clips, to clearly show the effect.

I don't know of a workaround, so this makes it impossible to use a wipe file without video quality suffering.

    I should have mentioned: I have melt 0.8.0.

    This problem occurs in the SSE-optimization for the image processing. Commenting lines 377 - 387 in transition_composite.c, which invokes the SSE code avoids the problem. I will ask the author of that assembler code if he can take a look into it.

    Fixed in git commit 2aaa902. I will close this ticket on the next release.

    Awesome, thanks! I've rebuilt the Debian package with the patch applied, and it looks good here.
