Calibrating Video / Time
Live scoreboards are synchronized with time information. SidelineHD is pre-calibrated to work with most cameras and setups.
|
If scoreboards / Radar change BEFORE the action happens, or in ways that seem “off” from the action, you may have a time synchronization issue. Follow these directions to make any necessary adjustments. |
Check Your Mobile Device Clocks
These phones need to have accurate clocks.
-
Pocket Radar / Stalker Radar app must have clock within 0.25 seconds of actual time
-
sidelineSCORE / iScore app must have clock within 1 second of actual time
If the clocks are not accurate, overlays will be presented at incorrect times.
On your mobile device, visit the website https://time.is to see how accurate the device's clock is. The precision +/- will be shown in the app.
Time-Sync Test Your Video
You may need to tune your timing settings if:
-
Your video goes to another streaming service before it goes to sidelineHD (restream, Vimeo Producer multi-destination).
-
You use an intermediate video switching device (OBS, ATEM Mini Pro, Mevo multi-cam).
Troubleshoot timing issues by recording a short live broadcast. Set up a test as follows:
-
Go live to your “usual” sidelineHD setup, in your “usual” way.
-
Use the EXACT SAME equipment and apps you use on game day
-
Use the EXACT SAME type of connection (cellular or hotspot data, not home WiFi)
-
Aim your camera at this web page: https://time.is/GMT
-
Record 90 seconds of content. Enough to see the clock overlay tick forward by one minute.
-
Watch your video. The overlay clock (it’s now on the top-left of the scrren) should tick forward with or just slightly (0-1s) AFTER the clock on your computer screen advances. Click here to see a successful video test.
Adjust Overlay Time Offset
If your video sync needs adjustment, you can adjust the timing of overlays and clips.
- Stop your camera's stream to sidelineHD.
- Navigate to your sidelineHD camera settings (Settings -> Stream Settings -> Camera Settings). When your camera is pointing to your team, click on the three dots and the the Advanced Settings button.
- Click on the + and - buttons to shift the overlays forward or backwards in time. Be sure to click save.
