5.4.3 Extension
– Video
This allows you to specify all custom or non-standard resolutions and indicate
whether the resolution is native.
To specify the video identification code:

Click the video identification code dropdown box and select the desired
resolution. (To remove, click the Remove button.)

Native resolution defines ONE additional native video resolution in addition
to the one specified in the Detailed timing of the first block. Although the
software does not prevent this, we recommend setting only one video
resolution as a Native one. If you do so, change the value of
“total number of
native DTD” field to 1.
