There are a few things happening there that make that effective. On the beat, video slows down. That could be created using using a time effect(timewarp) or just time remapping the layer.
Next the video is duplicated twice and masked and stacked above the original layer. Position keyframes move the 2 upper layers into place. The opacity of these layers isn't 100%, and with a couple of keyframes they fade quickly out, revealing back the original image.
I made a very simplified version of the effect to illustrate the technique.
