About video scaling settings
The AppCenter video scaling feature allows you to play clips with different aspect
ratios and picture resolutions on the same play channel.
AppCenter handles video scaling as follows:
• When recording a SD clip, you should specify whether the clip is standard or
widescreen video. This sets the clip aspect ratio attribute. This attribute is saved as
part of the media file. If the SD clip is played out on a HD channel, the aspect ratio
attribute is recognized.
• SD material that is transferred or recorded into the system, along with its audio and
metadata, is upconverted with selected aspect ratio when played on an HD channel.
HD material is downconverted along with its audio when played on SD channel.
HD and SD clips can be played back-to-back.
• Agile playout of mixed format clips displays with default or selectable modes such
as bars, crop, or stretch on both SD and HD outputs.
• During play channel setup, you must select the video output for each play channel–
standard or high definition. This will determine if the clip picture resolution needs
up-conversion or down-conversion. To set up the play channel video type, see
“Play channel video setup” on page 159 .
• For each play channel you must specify the active format description (AFD)
settings to use when the picture image needs to be resized. Selections include crop,
bars, halfbars and stretch. For more information, see “About aspect ratio
conversion modes” on page 153 .
• For the highest video quality, select a video output format that eliminates the need
for up or down conversion.
• AppCenter can play clips with different aspect ratio attributes in a single playlist.
NOTE: Some video output connectors become inactive for some video type
selections. For more information on video output connectors, see the K2 System
Guide.
