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:

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/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.

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