Hi lfgh85,

the analysis process with ImageJ is independent of whether you load the movie as quicktime, avi or whatever. If you have single frames in a folder, use File>Import>Image Sequence, it will also open the images as a stack.

Concerning the conversion:

If you have ffmpeg, a typical command might be
  ffmpeg -i INPUT.mov -pix_fmt nv12 -f avi -vcodec rawvideo OUTPUT.avi

Maybe first try whether VLC (www.videolan.org) can open your file; if it can't, ffmpeg usually won't do it either.
