Session settings

Recording continues while you pause, scrub, or mark a rep. End camera stops capture and joins all added reps. Without any added reps, it opens the full recording. Live returns to your selected delay during capture.

Rolling buffer 00:00

0 MB in memory

The live replay buffer holds up to 2:30. The full session is recorded separately from Start camera until End camera, including microphone audio. Save it before starting a new session or reloading.

Session guide

Browser prototype notes

Scrub the bottom timeline to the first frame of a rep and tap Start. Scrub forward to its last frame and tap Stop rep. Each completed selection is added to your rep video. Repeat for the next player. End camera joins the added reps and removes the gaps, keeping the audio and waveform. Undo last rep removes the most recent addition. Save rep can also save just the current selection. Live returns to your chosen delay. Marks expire when their footage leaves the rolling buffer.

Frames are retained at up to 15 fps at 640 × 360, with microphone PCM audio and timestamped waveform peaks. Playback and the waveform use one review clock. Browser camera and microphone input latency can differ, so capture alignment is approximate and has not been validated for precise sports timing. Frame stepping selects retained frames during live replay and uses approximate camera-frame seeks during full-session or joined-video review.

Use Chrome or Safari in a separate browser tab for camera access. Microphone playback starts muted; headphones help prevent feedback. Keep this tab visible. End camera (or hiding this tab) stops capture and opens your full recording for review. Save it before reloading, closing this page, or starting a new session. The full recording stays temporary in this tab. No media is uploaded. Media stays temporary unless you choose Save rep. Work-device camera or website restrictions may still apply.

Save a video clip

Ends at the frame you were reviewing. Includes recorded audio at normal speed. Preparing a clip takes about as long as the clip itself. Keep Safari visible.

This replaces the current recording. Save any video you want to keep first.

Building your rep video

Only completed Start rep / Stop rep selections are included. Keep Safari visible while the gaps are removed.
