This application records jury replay videos automatically, using the clock and decision information sent by owlcms. The jury can immediately watch the replays using a web browser. The replays are trimmed to remove idle time before the actual lift.
The program was initially meant for regional, national or multi-national events that use a single replay camera per platform, but now supports multiple cameras.
As an additional benefit, this creates a full video archive of all the lifts in the competition, organized by sessions, correctly labelled with the athlete, time of day, lift type and attempt number.
Note: this version requires owlcms version 56.0.0-beta or newer. Use "Install Additional Versions" and "Show Prereleases" to get it.
- Raspberry Pi 5 with SSD or Raspberry Pi 500 with a large-enough SD card/an external SSD
- Windows 10/11 on a recent laptop (a good GPU will be required for multiple cameras)
See the Equipment Setup notes at the bottom of this page.
- The replay app makes the replay video available on a web page that updates automatically as videos become available. Videos are listed with the most recent at the top.
- Clicking on a link opens a tab where the video can be seen, paused and restarted at will.
- The jury simply switches tabs to go back to the jury console or jury scoreboard

The replay application is designed to be usable on the jury laptop. Typical setups:
- A dedicated good quality USB webcam is connected using an Active USB cable (to account for the distance)
- A regular camera with HDMI output is connected using a HDMI-to-USB capture adapter. If this camera is also used for streaming, then a splitter or a pass-through adapter is used.
- Professional SDI feeds are used from the cameras. The SDI to USB conversion would take place in the video control room, and the jury would access the replays using a browser. Multiple instances of the application would run on a a single computer if needed.
