Channel tag  

Here you can assign a channel to a tag, tags are like groups that make it easier to find channels. Tags 
are used by the DVS-200 web interface and the NVD-30/35 decoders in set top box mode to group 
channels. 

Once your assign channels tags you can quickly find all channels with that tag using the dropdown 
menu on the DVS-200 web interface.

The following options are available when transcoding or encoding from Blackmagic Design sources.

Select Baseline, Main or High compression profiles

output bitrate, this setting does not affect visual quality.
