Write a video capture application

I am looking for a developer to write a software application that will perform video capture of a concurrently running game's screen. The application will need to meet the following requirements: -Simple UI to start and run the application -Must run on both Windows and Mac OS -Code will be version controlled with online git repository -Blur or delete both player names from the game screen -Save videos in web friendly format, resolution, and file size -Save a game log of some basic info -Game time -Both player classes -Number of rounds -Compress video/log into a single compressed file -Save compressed file to an easy to find location -Possibly a user defined location -Only the game window is captured (no overlays or mouse) -Possibly allow the video to be faster than real time (i.e. only capture 15fps but play back at 30fps) Please include in your bid what language you will be programming.
