I had to dig through the archives of all references & sources. It’s up to 2.9Meg (without all of the reference photographs).
Here is a hi-def youtube link that is much better:

HOWEVER, to see the action your system must be able to step frames in fractions of a second. To do this, you stop the play, then move the red sliding dot precisely & see the dot shift by a few pixels (horizontally). You should be able to get at least 4 individual steps (frames) before the time stamp advances to the next second. If your system only advances a full 1 second or worse 2 seconds, you lose the important dynamic action. It also helps to see this on a 27” hi-res display (as the bubble formation foam is more faint emerging and flowing up in the water).
Bubbles are round (spherical) not squarish.
You might want to check that link, it’s the same as in #1672
