Avid AMA Linking and Audio

Avid Media Composer 6MediaReactor Workstation and MediaReactor Lite add support for a wide variety of file formats to Avid Media Composer, including HEVC, AS-02, IMF, DNG, VRAW, CDX, YUV, and many more.  These files can include a mix of audio rates (normally 44.1, 48 or 96 kHz), and Media Composer requires some setup to allow them to be used in a standard project.  

Loading Mismatched Audio Rates

If you are AMA linking a file with the same audio rate as your project, it should work normally without adjustment.

If the audio rate of the incoming file is different, then the file will not play properly, and will produce an error message.

You will need to change the 'Source Settings | Audio | Change Sample Rate ...' settings. To start, load the file with the MediaReactor AMA as normal:

Load AMA Screen 1

There is more information on AMA loading here.

Once the file is linked, go to the Source Settings | Audio | Change Sample Rate ... menu

Select Audio Conversion

In the setup, set the audio rate to the same rate as the file you are loading.  Do not set it to the project rate, or the file will not play, and will display an error. The audio sample rate must match the file you are loading.

Set Up Audio Conversion

To check whether this is set right: Seek to and view a file in Media Composer. When you try and play it with the wrong setting, it will give the error message "Acquisition Context Error" (if you incorrectly set the rate to the project rate), and won't play.
