What ThrowSage does

A short tour of everything the product currently offers, and where each thing lives.

Your throws

The Throws page is your library. Every throw is a card carrying its name, date, a thumbnail you can hover to preview, and four numbers: Speed, Distance, Duration, Turns. You can sort by date, speed or distance, select several at once, and archive the ones you are finished with.

Cards also carry badges when they apply — for example when a clip was stabilised, or when camera movement was detected during the throw.

The report

Every finished throw gets a report: headline release speed, estimated distance and turn count, a per-turn breakdown of speed, support phases, separation and orbit tilt, and body position through the throw. It saves to PDF. Reading your report

The 3D viewer

Your throw rebuilt in three dimensions, with the hammer's path, the throwing circle, and overlays for leg planes, back tilt, separation and the extremes of the orbit. Step through it frame by frame at up to one tenth speed, with your original video kept in step alongside. Using the 3D viewer

Comparing two throws

The Compare page puts two throws side by side — both videos, both 3D viewers, and a table of release speed, estimated distance, turns and duration with the difference between them. Playback is synchronised between the two by default, so the same instant in both throws stays lined up as you scrub.

Fixing what the analysis got wrong

Any throw can be marked up by hand: where the circle is, where the throw starts and ends, which foot is down, and where the hammer is in frames it was lost. Re-run the analysis and your marks are used. When tracking fails

You can also trim a clip down to the throw itself, without leaving the browser.

For coaches with several athletes

  • Roster — every athlete, their throw count, and a profile page with total throws, average and best release speed, a release-speed trend across their throws, and their full throw history.
  • Team Analytics — a squad-wide roll-up: number of athletes and total throws, and a per-athlete table of throws, average speed, best speed and average distance, ranked fastest first.

What it is not

  • It does not measure where the ball landed. Distance is estimated from the release.
  • It does not judge your technique or tell you what to change. It measures; the coaching is yours.
  • It is not a live tool. Analysis takes minutes, not seconds.
