Get 33 markerless keypoints from videos for range of motion measurements, rep counting, body movement tracking and more

No. A single video from a phone is the whole setup — no markers, no suit, no capture volume, nothing to calibrate. Film the movement square-on to the plane you care about, with the whole body in frame and the joints unobstructed.

Fourteen, as angles in degrees on every frame, using an all-clockwise convention where 180° is a straight limb. Eight are measured by the engine itself — both shoulders, elbows, hips and knees. Six more are calculated from the detected landmarks: both wrists and ankles, the neck, and the trunk's lean off vertical. Every download says which is which, joint by joint. The landmark export goes wider still: all 33 pose keypoints per frame, from head to feet, with depth and visibility per point where the engine provides them.

Yes, on Pro and above. Pick from a zero-lag Butterworth low-pass (the convention in human-movement research, 4th-order, 6 Hz by default), Savitzky–Golay, a median filter, a moving average, or a Kalman filter with backward smoothing — each at three strengths. The charts, the live readouts and the min/max/range figures all update together, and the downloads carry the exact filter settings in the file so a colleague can see what was applied. Nothing is overwritten: the filter is a lens over the stored measurement, so switching it off gives the raw angles back. Which one to reach for depends on what you are fighting — a median is the one that removes a single wild frame where a limb was occluded, while Butterworth and Savitzky–Golay reduce general jitter without pulling the peaks in, which matters because a range of motion is read off the peaks.

It measures what a single camera can see, so the honest answer is that it depends on your footage. Angles are computed in two dimensions from the camera's viewpoint, which means a joint rotating out of the filmed plane will read short, and occlusion, loose clothing, low frame rates and steep camera angles all cost accuracy. Film square-on to the movement for the closest results. We have not published a validation study against marker-based motion capture, so treat the numbers as a repeatable measure of what is in the video rather than a lab-grade ground truth.

The CSV files open straight in a spreadsheet — one row per frame, one column per joint angle, or per landmark axis. The JSON is for scripts and pipelines. Your tags and comments come out alongside the numbers with their timecodes, so the notes stay attached to the measurements.

A token buys 12 seconds of analysed video — 5 tokens a minute. So 150 tokens is half an hour of footage, 600 is two hours and 1,800 is six. Every analysis costs at least one token, and clips filmed above 30fps have more frames to process so they cost a little more. You are only charged when an analysis completes; if it fails it costs nothing. The allowance resets on the 1st of each month (UTC) and belongs to the team, so everyone in the workspace draws on the same pool.

No. Range of motion and biomechanics needs nothing but the video. Exercises export as portable JSON that defines every angle from standard body keypoints, so any pose engine — MediaPipe, ML Kit, Apple Vision, MoveNet or a model of your own — can run them with the ready-made runtimes and adapters from the Export tab. The QuickPose SDK is the shortcut on iOS and Android: it measures the angles itself, so the runtime counts reps without you writing any pose code. That licence is sold separately.

Yes. Pick your Android engine in the Export tab — the QuickPose SDK, ML Kit or MediaPipe — and you get a ready-made Kotlin runtime and an adapter for it. The exercise JSON is the same file your iOS or web app uses.

Any time. Billing runs through Stripe, and the team owner can upgrade, downgrade or cancel from the billing portal in the app. Cancellation takes effect at the end of the paid period.

It depends on how well your stages describe the movement. Start with the default tolerance, test on device with feedback visible, then tighten or widen the angle windows and re-export.
