What we saw

This clip couldn’t give numbers, but the key moments are real: here they are on the clip.

Approximate: the moment is drawn hollow and isn’t held.

From behind we can follow the action, but knee, trunk and stride numbers need a side-on view.

Side-on, square to the pitchStand level with the bowling crease, on the side of the bowling arm, so the run-up crosses the frame.
Tripod at hip heightA steady phone at about 1 m keeps angles true. Lean it on a kit bag if you have no tripod.
Slo-mo at 240 fpsSwitch the camera to Slo-mo. At 240 fps the arm and the landing foot stay sharp; 120 fps works too.
Run-up to follow-through in frameStart recording before the run-up and stop after the follow-through. Keep the whole body in view.

What the camera gave the analysis to work with.

Frame rate: could be better.Fine for the key moments. Slo-mo at 120 or 240 fps makes angles and scores accurate.
Slow motion: could be better.Exported already slowed down, by an amount we couldn’t work out, so no times or speeds are shown. Use the original file from the phone that filmed it instead.
Framing: could be better.Part of the body left the frame. Keep the whole action in view.
