CinePaint

CinePaint is a computer program to paint on and retouch bitmap frames of movies. It is a fork of version 1.0.4 of the GNU Image Manipulation Program (GIMP). It is likely the most successful open source tool in feature motion picture work today. It is free software under the GNU General Public License.

Under its old name Film Gimp, CinePaint has so far been used for films such as Scooby-Doo, Harry Potter and the Philosopher's Stone, The Last Samurai and Stuart Little.

Features that set CinePaint apart from its photo-editing predecessor are the frame manager, the possibility to do onion skinning, and to work with 16-bit and floating point pixels for HDR. CinePaint supports a 16-bit colour managed workflow for photographers and printers, including CIE*Lab and CMYK editing. It supports the Cineon, DPX, and OpenEXR image file formats. HDR creation from bracketed exposures is easy.

It is available for Linux, BSD, UNIX-like OSes, Mac OS X, and SGI IRIX. Currently support for Windows is broken.

Glasgow, a complete new code architecture for CinePaint, will make a new Windows version possible and is currently under production. The Glasgow effort is FLTK based.
