In situations where low latency is required for IMAG type shooting (Camera to projector or TV for live events) here are a couple of suggestions for lowering latency:
Turning on low delay mode
Disabling the audio
Keep the bitrate ~10mbps or less
Set the coding mode to random intra refresh
When you get down to ~1/4 second (6 or 7 frames) it’s important to consider that there is additional delay added by the camera’s output and the monitor. Beam adds a minimum of 1.5 frames of delay however, it doesn’t promise 1.5 frames delay from glass to glass. If you need a zero latency solution, Teradek also offers the Bolt series.
