CinePaint is an open-source computer program designed for painting and retouching individual frames of film. It originated as a fork of version 1.0.4 of the GNU Image Manipulation Program (GIMP). CinePaint gained recognition as one of the pioneering open-source tools used in professional motion picture visual effects and animation.

Its primary advantage over the standard GIMP was its support for high bit depths (greater than 8 bits per channel), a crucial requirement in film production. While the GIMP has since incorporated support for higher bit depths, CinePaint remains a specialized tool for film frame retouching. It is distributed under the GNU General Public License.

The right-hand panel conveniently houses shape and drawing tools alongside a customizable color palette. Essential image editing and modification options are readily accessible in the top menu bar. A minor drawback is the inability to customize the interface and create personalized toolbars.
