If you download the GIF, and go through the individual frames, there is a distinct jump cut you can see when the kid is 'thrown from hand' into the water, because the people in the shallow end of the pool are in different positions on directly adjacent frames (the kid actually must have jumped off the pool deck, and the frames that woulda shown that were edited). A similar 'jump cut' occurs between frames 15 and 16, when the kid 'disappears', and as the hand is clasping... This works very well because the final frame rate is low (allowing better choices of frames to 'drop') and the resolution also being low and the jerking of the camera helps further obscure the cuts.... I believe it would have been far more difficult to pull-off if the res and frame rate were a lot higher..... Nevertheless, it's nice work.
