Hi Arie,

some alternative ways for converting:

- Use FFMPEG (free video conversion software, command-line based) to
convert to a format readable by ImageJ. E.g.
 ffmpeg -i infile.avi -pix_fmt nv12 -f avi -vcodec rawvideo outfile.avi

- The icy video importer plugin should also read the CRAM file (I have
never tried it, however):
  http://icy.bioimageanalysis.org/plugin/Video_Importer

By the way, CRAM is Microsoft Video 1, an early lossy compression.


Concerning the Quicktime file, obviously the first thing to check is
whether it works in Quicktime player or VLC; if it does, it might be worth
sending it with a bug report to the Bio-Formats team.


Michael
