Alright, so in this video Blake (the blackhaired catgirl) dodges some lightning fired off from a large serpent/dragon thing. She rolls from one location to another in mid air to avoid these blasts. This movement can be measured and compared to the lightning to find out how fast Blake was moving.
General Info and Jacket Size








So a couple marking on this shot: Blake's Jacket is 67 pixels in dark blue. The height of Blake is 220 pixels in red. The length of Blake is 59 pixels in light blue. Blake's hypotenuse (true height): 227.77 pixels. Blake is 1.68 meters talls, and thus we find that each pixel is 0.00738 meters after diving her height in meters by her height in pixels. This mean that Blake's jacket is 0.4945 meters long from collar tip to edge.
The starting point of the lightning bolt is located at cooridnate 470x352 as a 2 pixel black dot; now on to the next step.
Lightning Distance and Multiplier








Here we see the second frame. Unfortunately the tip of the beam is now off screen, which makes this a lowball (probably not that big of one considering it looks like the cone from the tip of the beam is still visible). Half the beam's diameter is 64 pixels, shown in light blue, so that is where we will positioning as the center (even though the tip of the beam is probably farther right by an unknown amount). The length of the beam is 73 pixels in black. The height of the beam is 353 pixels in red. The hypotenuse of these is 360.47 pixels, which will be the true length. Plug that into our 0.00738 meters/pixel amount to get 2.66 meters moved. This occured in 1 frame, and out of a 24 FPS video this would mean 2.66 meters were covered in 0.04167 seconds, yielding a speed of 63.8349 m/s. But wait, lightning really moves at 4.4x10^5 m/s, so we need to divide this by our speed to find how much faster than normal they are moving.
4.4x10^5/63.8349= 6892.781x faster than normal
Blake's Movement








So she rolls this far in 3 frames. For reference that is 0.125 seconds. So, how far did she go? Lets angsize the two shots and get a result.
For the first frame:
2atan(tan(70/2)*(67/480))= 0.13208092382 Radians. Now we put this into degrees.
0.13208092382x180/pi= 7.56767948907 Degrees. Now we plug into angsize to see how far away she is.
Distance: 3.7385 meters away
For the second frame:
Blake's Jacket is now 76 pixels in length in red and 135 pixels in height in blue. Blake's Jacket 2nd Hypotenuse (Jacket real size): 154.92 pixels
2atan(tan(70/2)*(154.92/480))= 0.3034961585 Radians
0.3034961585x180/pi= 17.3890489805 Degrees
Distance: 1.6168 meters
Distance moved between frame 1 and 4: 2.1217 meters. Using 0.125 as stated before we get 16.9736 m/s. Now we plug this into our previous multiplier.
6892.781x16.9736= 116995.3076 m/s
Final Tally:
Blake Dodges Lightning: 116995.3076 m/s, Mach 341.0942, Massively Hypersonic
