Slow Motion Video Analysis

If you use any type of slow motion video analysis for you or the athletes that you coach Olympic Lifts to, what do you use?

I ask because I am only aware of Dart-fish, and want to hear the opinion of others before I spend any money

Also, without being rude, lets not start a “you don’t need it” debate (as we do, for a school Biomechanics project)

Thanks

kinovea is freeware. can’t use it on a mac, though. can use it on a PC.

I just use quicktime player. With the left/right arrow you can go frame by frame.
