AI video analysis / Throws

Go through your throw frame by frame. Get coaching notes on the same clip.

From the start of the movement to the release, a throw is over in a second or two. Film it, upload the clip, and traqqer returns a written review with one thing to fix and drills for your next session. It covers shot put, discus, javelin and hammer.

  • Under 1 minute
  • Whole body in frame
  • Film from a safe spot

traqqer does not measure how far you threw. It does not track the shot, discus, javelin or hammer, so it does not give release speed or release angle. It reads body positions: joint angles on the frame you stop at, and a written review of the movement. Treat the review as a hint for training. It is not a diagnosis or a promise of a longer throw.

This is the kind of review you get

What comes back for one throw

A shot put clip might come back with a note on how you set up at the back of the circle, where your hips and shoulders are in the power position, and whether the front leg holds firm at release. The Improvements tab says what to change. The Drills tab lists practice for that point. In the 3D view you can stop on the release frame and read the elbow and knee angles.

This is an example. The wording and the angles depend on your clip.

Each review has four tabs

Evaluation

A short written summary of the whole throw, from the start of the movement to the release.

Good Points

What to keep. Useful when you change one thing and do not want to lose another.

Improvements

What to fix next, such as the position of the hips at the power position or the block at release.

Drills

Practice matched to the improvements, for your next session.

The two screens you will use

The written review tells you where to look. The skeleton view lets you check that moment in numbers.

Questions

Does traqqer measure my throw distance or release speed?
No. traqqer gives you a written review of your form and the joint angles of your body on each frame. It does not track the implement, so it does not give distance, release speed or release angle.
Which throws does it cover?
Shot put, discus, javelin and hammer. On the upload screen choose Throwing as the video type. You can also add a short note, for example which event it is and what you want checked.
How should I film a throw?
Keep your whole body in frame from the start of the movement to the release, and keep the clip under one minute. For the 3D skeleton view, use a clip under 20 seconds. Always film from outside the cage or the landing sector. A normal phone video is enough.
Does it work for rotational throws?
You can upload discus, hammer and rotational shot put clips. When you turn away from the camera, part of your body is hidden and the joint angles on those frames are less reliable. Check the angles on frames where the camera can see the joint.
Is there an Android version?
Yes. traqqer is on Google Play and on the App Store.
Is it free?
You can try AI video analysis on the free plan. Premium is $7.99 a month for unlimited analysis.
