Sometimes due to camera feeds being delayed you might also want to delay data coming from Scoreboard OCR. Otherwise you would have score updating before ball hits the basket.
Here are instructions:

1. Open scoreboard camera in vMix and set delay under Advanced → Delay. Be cautious, the longer the delay, the more RAM vMix will use
2. Activate NDI output and set Alpha channle to 'Premultiplied' in vMix for scoreboard camera (please see screenshot below)
3. Use the NDI input in Scoreboard OCR

Here is the workflow:
Scoreboard camera input → vMix input with delay → vMix NDI or vMix Virtual device output → Scoreboard OCR input
