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 system should process AFD (for output only, on a per-channel basis).

When recording, the following AFD settings are available:

SD

HD

Undefined Undefined ( Undefined means no AFD has been set; the clip remains as is.)
16:9 Full screen 4:3 Pillarbox
4:3 Full screen 16:9 Full screen
16:9 Letterbox 14:9 Pillarbox
14:9 Letterbox 16:9 Full screen with 4:3 center

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 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.

Note: Other methods of expressing AFD, such as video index or bar data, are not supported.
