Can't get SDI audio from SDI out

 

@Eiffert : I have my  video  configured  for SDI  and taking  SDI  video out  form Aximmetry   to my  external  mixer and  monitors. using a BBM Mini Monitor. Video on the SDI is  OK  however I cannot  get the audio to work on the SDI. How do I reconfigure to allow for  embedded audio on the Out  ports.

Hi Linford,

The Audio Level module does not change the loudness of the audio; it is used for visualizing the loudness. This module outputs a vector value (green pin) that corresponds to the loudness of the audio, instead of outputting the audio itself (blue pin). If you want to adjust the loudness or mix together the three audio connections, you probably want to use an Audio Mixer module.


To embed audio into a video, you need to connect one audio pin under the respective video pin. You can find more information about this process here: https://aximmetry.com/learn/virtual-production-workflow/starting-with-aximmetry/aximmetry-composer/basics-of-the-flow-editor/#exposing-area-of-input-and-output-pins

Warmest regards,

I reviewed the documentation but could not find anything that looks like it may work in my application.

 My ideal solution would be to find some way to  route  the PCM  audio from  the pin  that's paired with the video above it to an external mixer , and then feeding back the mixer audio output to the audio pin position on the right beneath the corresponding video. In that way I would have external control of the audio, and at the same time embed it with the SDI video.  Not sure how to achieve this .

Hi Linford,

To output audio separately without embedding it in a video, you should use an Audio Out module. Once the audio is mixed externally, you can bring it back into Aximmetry using an Audio Input module.
Keep in mind that this round-trip to the external mixer will introduce some audio delay. To ensure synchronization between audio and video, you will likely need to delay the video using a Delayer module:

Thanks Eiffert

Still struggling with how best  to  control  3 channels of  audio externally. I can see from my Record_3 module , when I use the Peeker on the Mixed Audio  out , there is 16 Ch  32 Bit  audio. Can I route this audio out of that pin , possibly  through the  sound  card of the  PC , and into a physical external mixer. On that  mixer  which I  will need to source, I  will  need  to be  able to separate  the 3 channels of audio,  assigning  each to separate faders of the  mixer,  and then routing the mixed mono audio back to the Aximmetry  PC - probably  through the line in of the  sound  card. Can this  audio now serve as the input source for one of your audio  modules,  and then take the  output of that  audio  module , pairing it with a video out  on the right  side.

Hi Linford,

Yes, you can connect the Mixed Audio pin to an Audio Out module to output sound through a sound card.


I hadn't realized before that your external mixer processes sound by channels rather than different sound inputs. You can use the Audio Merger, Audio Splitter, and Audio Channel modules to combine different audio channels if the Record_3 compound is not enough.
