HighlightReelz, a sailboat-race replay marked in real time

Field notes

The prototype splits the workflow into Viewer, Admin, and Debrief sandboxes rather than presenting a single finished application. Viewer marks can be shifted six seconds backward, while Admin entries such as a gun start or mark rounding are intended to help infer the remaining sequence. The short built-in clip is about 17 seconds and uses stretched timings, so the page specifically asks testers to load their own race footage. Nothing is saved, and entries made in one sandbox do not appear in the others.
