DNxHR Performance Configuration

Assuming that the server is set up to work in the UHD mode, and a DNxHR codec is used for
playout, then the Avid Video Engine needs to be configured in a specific way.
To configure Video Engine for DNxHR:
1. With an SSH client, log into theLinux server and navigate to:
/data/VE/bin
2. Open the VideoEngine.xml configuration file and locate the following line:
<Rule Enable="No" Demuxer="ffmpeg" Essence="dnxhd" Decoder="AvidDNxHR"
Options="Instances=3" />
3. The Rule needs to be enabled for the UHD DNxHR playout:
<Rule Enable="Yes" Demuxer="ffmpeg" Essence="dnxhd" Decoder="AvidDNxHR"
Options="Instances=3" />
4. In case of HD playout of DNxHR and playout of DNxHD clips with alpha, then the Rule has to
be disabled:
<Rule Enable="No" Demuxer="ffmpeg" Essence="dnxhd" Decoder="AvidDNxHR"
Options="Instances=3" />
