PIV from avi file. Form stacks

Hi
Im tring to do PIV using imageJ plugin. The source is a video *.avi formed with 600 frames.
What Im going to try is:

  1. Split that video avi into 300 pair of images. (Using opencv python scripts)
  2. Run a macro on ImageJ to save each pair of images as a stack. I will end up with ~300 stacks.
    Then analyze each pair using PIV macro.

Does this sound reasonably? Have anyone done something similar?
Thanks
