Comparison Video Techniques

Duncan Atwood

1. Humans are very good at “Spot the Difference” – comparisons make it easier.

2. When looking at a single picture, we compare it to our stored (remembered) pictures. We hope they’re accurate.

3. Quantitative comparisons have more impact than qualitative comparisons-
ONLY if audience really understands them.

4. Position comparisons – measure angles and compare, ONLY if images are taken from the same angle.

a. Different angles show (or hide) different points. Work to get angles to
show what you’re looking for or don’t bother.

5. Rhythm and timing comparisons – synchronize start point, then count frames to next important point of the event.

6. Try to compare several models (experts) to your subject. The Internet has many sources. www.macthrowvideo.com, YouTube, www.pocketvideos.com, etc.

7. Learn about your camera – shutter speed is very important. For most filming, 1/2000 is fast enough.

8. Get close – avoid using the zoom – and try to fill the frame with the athlete.

9. Ask your athletes for help in using video editing programs. The learning curve can be unacceptable on your own, but easy when you’re shown.

10. Experiment with pulling out frames from your comparison. It’s easy, and offers
more frequent access to the images.
