We will implement a user interface in Kdenlive and each software will do

Our priority is to propose a working solution to correct color and
light. This is for Kdenlive next release, not in 6 months. Otherwise,
advanced users may not use Kdenlive or may turn to closed software.

Stefano, when do you think the wrappers to mplayer filters and Gimp
filter will be ready? I am a beginner in C. Can I propose some code, or
would it be more easy for you to propose your own solution?

I am not familiar with Google summer of code and I have no idea what
this implies in terms of collaboration.
