Calibrating your camera

Calibrating Video / Time:
 

Check Your Mobile Device Clocks

When streaming with sidelineHD and using integrated apps and devices, accurate clocks and timestamps are important. Without accurate clocks and timestamps, overlays such as scoreboards and radar readings, may present at incorrect times.

To check how accurate your mobile device's clock is, we suggest visiting https://time.is. Here you will see how accurate your device's time is compared to your timezone down to the millisecond. 

If your clock is not in-sync with the correct time, we suggest restarting your device as well as double checking your device's timezone. For reference: 

• Pocket Radar Sports App and Stalker Radar app must have clock within 0.25 seconds of actual time

• Your streaming device,  sidelineHD app and iScore app must have clock within 1 second of actual time

   

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).

   

We suggest trying to troubleshoot these issues by recording a short live broadcast.  Set up a test as follows:

1. Go live to your typical sidelineHD setup in your usual way
   • Make sure to use the same equipment/apps and connection (cellular or hotspot) as you would use on game day. The goal is to recreate your streaming environment as closely
2. Aim your camera at this web page: https://time.is
3. Record 90 seconds of content
   • Enough to see the clock overlay tick forwards by one minute
4. Watch your video
   • The overlay clock (top-left of the screen) should tick forward with or just slightly (0-1s) AFTER the clock on your computer screen advances
   • View a video of a successful test here

Adjust Overlay Time Offset

If your video sync needs adjustment, you can adjust the timing of overlays and clips.

1. Stop your camera's stream to sidelineHD
2. Login to your sidelineHD account

   • Select the + to shift the overlays forward in time
   • Select the - to shift the overlays backwards in time
