ImageJ/FIJI cannot read Cinepak codec video files.
There are two plugins that attempt to address this for ImageJ: http://rsb.info.nih.gov/ij/plugins/jmf-player.html http://rsb.info.nih.gov/ij/plugins/jmf.html
But I found neither of them to work for me on the particular AVI Cinepak video I was given.
FFmpeg convert Cinepak
Instead, I used FFmpeg to convert to a more modern widely-compatible Motion JPEG format by typing:
ffmpeg -i video1990s.avi -vcodec mjpeg -qscale 1 test.avi
Uncompressed AVI output file size could be a factor of 10 larger than the Cinepak version:
ffmpeg -i video1990s.avi -vcodec rawvideo out.avi
Compress LOSSLESS FFV1:
ffmpeg -i video1990s.avi -vcodec ffv1 out.avi
You can also convert the AVI to a series of PNG images.
