Studying the wonderful GIF it's not clear to me the sequence of the two blows.
Ah sorry I thought it was obvious, but actualpy it isn't.
Those are exactly the same strokes from my handheld camera. When I made the original clip, I found that due to the animgif discolotation the blood is not really visible, so I took a strong zoom onto the scene and I put it before the original clip. So actually you see the same stroke twice. Once zoomed in, and then the original footage both slowmotion. And then Tatjana's reacrion with normal speed.
