Delay Audio on ATEM consolle

PostMon Feb 03, 2025 8:26 pm

Hi,
I have "ATEM Television Studio Pro HD" and I connected the audio output of my audio mixer to the XLR input of this consolle. I have the delay between this audio input and the cameras that I connected to the SDI inputs.
What is the delay that the mixer adds to the embedded output?
Thanks

Delay depends on any device you add.
Just adjust so it matches ;)

The ATEM delay is from 10 lines to a frame max if sources are not locked. Any other latency will be from the sources. Output displays have latency but have no effect on audio sync with SDI. I hope this helps.

Thanks to all for the answers, my situation is as follows:
IN-1: Sony HDMI camera
IN-5: Ursa Broadcast G2
IN-6: Ursa Broadcast G2
IN-7: Sony SDI camera
IN-8: Sony SDI camera

IN XLR: audio from mixer with church microphones

The PGM SDI output of the video mixer, with any camera selected, has the audio from the microphones (XLR input) delayed, it seems at least 10 frames. Is such a big delay possible?

Sorry for my bad English

Hello Paolo. In the setup you describe, the audio would typically be about 3-5 frames ahead of the video. It is not common for audio to be later than the video unless it is going through some sort of specialized processing. In the ATEM Audio Mixer you can set the delay for the analog audio input which comes from your console. Try setting it a few frames and see if it is better. That would be very common and normal. If your audio is really delayed from the video initially, I would look for the source of that delay and try to eliminate it. 10 frames is quite long. I hope this helps.
