External control of Aximmetry DE and audio delay

@Eiffert: I am using Broadcast DE in a live environment using 4 tracked cams without Billboard. So far I am relatively satisfied with the results with the virtual sets and video portion however I find that managing the audio is quite challenging for one operator who has to switch video inputs and control audio from the same Control Panel. I am using three microphones, connected to 3 cameras and embedding this to the camera's SDI. Is there a way of controlling this audio with an external device. In that way a second operator can be tasked with audio control while another concentrates on the video with the Control Panel. What device would you recommend..

The second issue I have with audio is that there is an audio delay where the audio from at least one camera arrives earlier - or later - than the other. The effect of this is that when the mic ports are open and audio is is being received from one source by by more than 1 microphone, it creates an echo. What is the best way to adjust for this audio distortion . I imagine this could be done by delaying the SDI output or maybe just delaying the audio.

Thanks

@Eiffert : some feedback on that audio issue would be appreciated. Thanks

Hi Linford,

You only need to delay the audio and not the video too, unless the video arrives before the audio.

Does the audio embedding happen in Aximmetry or does Aximmetry already receive the audio being embedded in the SDI?
If the audio is embedded in the SDI, you can use the Audio Level and Delay options available in the INPUT panel:

If not, you can achieve the same result using the Audio Delayer and Audio Fader or Audio Mixer modules:

Note, that you can use any of these module's pins on any Control Board you create.

Or you can use the [Common_Studio]:Compounds\Record\Record_3-Audio.xcomp compound for just this purpose of mixing the different audios.

Regarding exposing audio parameters to a second operator through a device, I can not provide specific device recommendations. However, you can connect pretty much any external controller to Aximmetry. The supported protocols and some devices are listed here: https://aximmetry.com/learn/virtual-production-workflow/setting-up-inputs-outputs-for-virtual-production/introduction-to-setting-up-inputs-outputs-for-virtual-production/#external-controllers
Note, that you could even use your phone or any device that has a browser to easily access the Control Boards of Aximmetry. It is achieved by an internal web server of the Aximmetry Composer and it is documented here:
