4.2 How to Test Latency Correctly?
Diagram Description: A diagram illustrates latency testing. It shows a camera connected via the wireless system (transmitter and receiver) to a monitor, with a separate audio path. Timestamps are displayed on screens, with an indication that 'Time1 minus Time2 is the latency'.
4.3 Audio and Video Out of Sync: If video is transmitted directly to the control room but audio via an audio mixer, latency can occur. The latency of the Mars Pyro H is around 60 ms. If video is sent through the Pyro H and audio via another path, there is a latency of 60ms.
Solutions:
- Transmit both video and audio through the Pyro H. For example, mount the microphone and the Pyro H on the camera together for simultaneous transmission.
- Apply a 60 ms delay to the audio on devices like the mixer or OBS software.
