Cinepak videos in ImageJ

If someone has sent you an AVI file with Cinepak compression, you may find that ImageJ/FIJI and other contemporary software cannot read the AVI file.

There are two plugins that attempt to address this for ImageJ:

But I found neither of them to work for me on the particular AVI Cinepak video I was given.

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

If you need no loss, you can do uncompressed AVI, but note the output file size could be a factor of 10 larger than the Cinepak version:

ffmpeg -i video1990s.avi -vcodec rawvideo out.avi

You can compress to LOSSLESS FFV1 by typing:

ffmpeg -i video1990s.avi -vcodec ffv1 out.avi

You can also convert the AVI to a series of PNG images.

ImageJ-Win64 won’t start

Upon freshly downloading and extracting FIJI for Windows 7 64-bit, I found that typing at the Command Prompt:


would do nothing.

I found that typing (once)
ImageJ-Win64 –cp jars/javac.jar

fixed the problem–thereafter, I could just click on ImageJ-Win64 to start.
