Applying AFD settings
Active Format Description (AFD) can be used to automatically determine the proper aspect ratio to
use for up- and down-conversions.
In AppCenter, you can specify the AFD settings:
• in the Clip Properties dialog box, for that clip only
• in the Channel Options dialog box, for newly recorded clips on that channel
You can also make settings in Configuration Manager to specify under what conditions the K2
Summit/Solo system should process AFD (for output only, on a per-channel basis).
When recording, the following AFD settings are available:
HD SD
Undefined ( Undefined means no AFD has been
set; the clip remains as is.) Undefined
4:3 Pillarbox 16:9 Full screen
16:9 Full screen 4:3 Full screen
14:9 Pillarbox 16:9 Letterbox
16:9 Full screen with 4:3 center 14:9 Letterbox
Channels with HD licenses need to set the AFD values when aspect ratio conversion has been
performed while playing out video. Channels that are SD-only do not perform aspect ratio conversion;
AFD values do not need to be adjusted on those channels.
Clips with AFD recorded on a K2 Media Client will play on a K2 Summit/Solo system, and vice
versa. Clips will have either ARC or AFD properties, not both. AFD in ancillary data is preserved
in the data track during recording.
