Open-source films (also known as open-content films and free-content films) are films which are produced and distributed by using free and open-source and open content methodologies. Their sources are freely available and the licenses used meet the demands of the Open Source Initiative (OSI) in terms of freedom.
- The license of the movie is approved for free cultural works. Specifically this is true for the Creative Commons licenses by and by-sa.
- The materials used in the movie (sources) are also available under a license which is approved for free cultural works.
- The movie and its sources are made publicly available via an online download or by other means that are either free or with a cost that covers reasonable reproduction expenses only.
- The sources should be viewable and editable with free/open-source software. If this is not the case, they must be convertible into such a format by using free/open-source software. The same applies to the movie itself.
- It should be possible to re-create or re-assemble the movie using the source materials.
Films or film projects which do not meet these criteria are either not open source or partially open source.

|This is a first time addressing of the huge lack in available free high quality footage for motion tracking, keying and cleaning testing. The material was recorded with the Sony F65 camera (4k native sensor, see also Ultra HD) and is formed by roughly 80,000 frames, each in OpenEXR half float files, in 4096 x 2160 pixels. This is 5 times more footage than used in the film. For the movie production the format encoding Rec709 “scene linear” was used in the processing pipeline.|
