Start here¶
ThrowSage turns a phone video of a hammer throw into measured numbers: how fast the hammer was moving when it left your hands, how far it went, how long each turn took, and how your body moved through the throw. You get a report you can read, and a 3D reconstruction you can spin around and step through frame by frame.
You do not install anything. Everything happens in a web browser.
The whole thing in four steps¶
- Film the throw. One camera, from the side, whole throw in frame. What makes a good video is the five minutes most worth spending — footage decides how good the analysis can be.
- Upload it. Sign in, drop the file on your throws page. Uploading a video
- Wait. The analysis runs on a graphics server somewhere else, and your throws page shows you which stage it is on. What happens next
- Read the results. A report of numbers, and a 3D viewer. Reading your report · Using the 3D viewer
If you only read one other page
Read What makes a good video before you film. Almost every disappointing result traces back to the footage, and re-filming is cheaper than re-analysing.
Whether you throw or coach¶
Those four steps are the whole loop for your own footage. Each analysis you run uses one of the analyses your invitation includes, so What makes a good video is the page most worth reading before you spend the first one.
The same four steps analyse each of your athletes' throws. Once you have throws from more than one athlete, the Roster and Team Analytics pages roll them up — per-athlete trends and a squad-wide comparison. See everything ThrowSage does.
If something goes wrong¶
The most common problem is the software losing track of the hammer — a small, fast, often motion-blurred ball. That is fixable by hand, and it does not require any technical skill: When tracking fails.
