Filming your riding is the single highest-leverage habit in surfskate improvement, for a blunt reason: the pump is nearly impossible to feel accurately from the inside. Riders swear their knees are bending while video shows two straight poles; flutterers feel steady, carvers feel like they're pumping. The camera settles arguments your proprioception keeps losing.
But a clip is only as useful as it is readable — by your own eyes or by video analysis. Here's how to film runs that actually tell the truth.
The non-negotiables
Fix the phone. No follow-cam. Tripod, bench, ledge, backpack against a curb — anything stable. A friend walking with the camera adds motion that makes body movement much harder to judge, for humans and software alike. Fixed camera, moving rider.
Landscape, whole body, head to wheels. The whole chain has to be in frame for the whole run — an analysis of your pump can't see a chain that's cropped at the knees. Frame generously; drifting out of frame mid-run costs you whichever seconds were the good ones.
10–20 seconds of continuous pumping. One honest run beats a highlight reel. The valuable information lives in continuity — how the rhythm holds across cycles, where it frays, whether the run builds — and cuts destroy exactly that.
60fps if your phone has it. Pumping is fast; more frames mean smoother tracking of joints in motion. It's one settings toggle, set once.
The two angles, and what each one sees
This is the part most people get vaguely right and specifically off: the two useful angles see different things, and neither sees everything.
Down the line: camera at one end of your run, and you pump straight toward or away from it the whole clip. This angle reads rotation — how your shoulder line swings between arcs, how the arm swing travels, whether the motion connects through the body, the rhythm of the carves. It's the angle for sequencing and flow.
Side-on: camera to your side, and you pump a short out-and-back line so you stay in frame. This angle reads the vertical: knee bend, compression depth, posture, stance width, how your weight splits between the feet. It's the angle for legs and stance.
Neither angle is the better one — they're two halves of a full picture. Down-the-line can't judge your knee depth; side-on can't read your rotation. If a report on one angle says nothing about your stance, that's the camera's geometry, not a gap in your riding. Alternate angles across sessions and you cover the whole rider.
Make the filming session count
A camera at the end of your line comes with a free bonus drill: Eyes Down the Line. Pick the phone itself as your visual target and hold your eyes on it the entire run — never on your feet. You'll get a cleaner clip and a better run in the same breath, because the board goes where the eyes and shoulders already went. (For side-on clips, pick a target at the end of the line instead — same rule, same reward.)
Film two or three runs per session, not twenty. Then pick your best one and let CoachVision read it — it turns a single phone clip into measurements of your cadence, rhythm, compression, stance and carve commitment, and tells you the one thing to fix next. Thirty seconds of setup, one honest run, and your practice stops being guesswork. That trade is available every session; take it.
