Hard shorebreaking waves. The crest of the wave @ 0:43 falls down in 25-26 pictures of 30 pictures per secondes. Makes 25,5 / 30 = 0,85 secondes. h = 0,5 * g * t^2. g is the constant acceleration of gravity while falling down, t the time of falling down. h = 0,5 * 9,81 m/s^2 * (0,85s)^2 = 3,5m (11,5ft). The Wave crashes with a speed of v = g*t on the surfaces of water v = 9,81 m /s^2 * 0,85 s = 8,33 m/s (18,6 mph). Nack cracking in the breaking zone I would say..
Some nice content, just not sure where your filming. Might want to pan left towards P.V., or right towards the jetty or pier so we know where you are, just to get our bearings.
