SDI audio input / Blackmagic problem (audio stutter)

Announcement SDI

 
Using Blackmagic cards and SDI embedded audio input, the following issue can appear.

When accessing the SDI audio using an Audio Input module, you can select Blackmagic cards as an Audio Device. This audio signal can suffer from a stuttering effect and demodulation.


To avoid the problem we recommend accessing the SDI audio input directly using a Video Input module (or any Camera compound, as they are all using Video Input modules). The audio then can be output for further purposes using the designated Audio pin output on the Video Input module / camera compound.


When using the Record_3-Audio compound, make sure you check the camera icon to use the SDI audio by the Video Input module. If the camera icon is unchecked, then the module will access the SDI audio using an Audio Input module.
