Sports video analysis for coaches

The video analysis app
for coaches.

Play a clip in slo-mo, stop on the exact frame you need, mark what you see and compare it with a pro's video, in sync.

Coming soon on Mac and iPad

See it

See how the whole body moves

Open a clip and Keendra draws a skeleton over your athlete through the whole movement. No markers, no sensors, just your video.

How the skeleton works

Put a number on it

Watch a joint angle change as the clip plays, as a value and a short graph. Keendra estimates twenty of them, from knees and elbows to trunk lean.

How joint angles work

Work on it

Keep your athlete centered

Turn on Follow and the picture zooms in and stays on your athlete as they move, on your screen and in the videos you send.

How Follow works

Show exactly what you mean

Pause on a frame and draw on it: lines, curves, arrows, shapes and angles with their degrees.

How to draw on a frame

Compare it

Go through a whole training block

Cut a long video into clips, one per attempt, and move from clip to clip. Analysis runs while you work, for one athlete or a whole group.

How to build a Session

See the difference between two attempts

Mark the same movement on two clips and they play together, start to end. Compare today's attempt with last week's, or with a pro's.

How Sync works
Two ski attempts side by side in Sync, with the clips of the Session above them

And everything around it.

Keendra is a sports video analysis app for coaches on Mac and iPad. Review an athlete's technique in slow motion and frame by frame, with a skeleton and estimated joint angles over the video. Compare two attempts side by side or stacked, then show your feedback on a big screen or send it as a video. It works with the clips you already film on a phone or camera, with no markers or sensors.
