2. what are the items on the screen (the barbell, plates ) that can have a known measurement and youcan use to set the scale of measurements.

4. For every attempt, identify the important keyframes that you will need to calculate the following for all 5 phases of the lift (Phases of the Snatch: https://thetraininggeek.net/blog/2014/01/03/presenting-the-5-phases-of-the-snatchclean-in-weightlifting)Links to an external site.

The amount of keyframes may vary between phases. Ideally, keyframes should contain enough information between them to allow an adequate analysis of the movement ( need your best judgment here).
