As of 10/31/2020, this is no longer being maintained. It should still work using an older GIT version with Windows 10 but it is possible with some effort to modify the patch file to work with the latest updated GIT.
To run CINELERRA-GG on a Windows 10 computer, you will need to have Cygwin installed on your system, along with the CINELERRA-GG static tar and a patched library: libxcb. This setup has been tested with Windows 10, version 1909, on an HP EliteBook 820 at 2.3 GHz.
This limited version provides core functionality at this time with the standard Windows FFmpeg executable, meaning that specific modifications in FFmpeg needed for CINELERRA-GG are not available. Limited capabilities include only a few render output formats available - for example mov, qt as mjpeg, and mpeg for videos and avi and qt as s16le for audio, but not mkv or mp4. This is due to the fact that several codec and utility libraries are not currently compiled to work with Windows.
