Applying AFD settings
Active Format Description (AFD) can be used to automatically determine the proper aspect ratio to use for up- and down-conversions.
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.
