About video scaling settings
The K2 Media Client video scaling feature allows you to play clips with different
aspect ratios and picture resolutions on the same play channel.
The SD-00 K2 Media Client handles video scaling as follows:
• When recording a 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.
• Both 16:9 and 4:3 SD resolution formats are supported for playout on the same
timeline. However, there is no automatic aspect ratio conversion on playout. If a
clip has the widescreen attribute set, that attribute is recognized and passed
through, but it does not alter the playout aspect ratio when played out on a SD-00
K2 Media Client. If that clip is played out on a HD-00 K2 Media Client, the
widescreen attribute is recognized and the configured aspect ratio conversion mode
is applied.
• You can only set a clip’s aspect ratio attribute when it is recorded. Once a clip is
recorded or imported, you cannot change the attribute. If you want to change the
clip’s aspect ratio attribute, you must re-record or import the clip.
• In some cases you might want to deliberately set a SD clip’s aspect ratio attribute
“opposite.” For example, if a clip is being recorded on a SD-00 K2 Media Client
and it already has an aspect ratio treatment, such as letterbox bars as part of the
media itself, you would not want to again apply letterbox bars when the clip is
played out. This could occur if the clip is played out to a SD output on a HD-00 K2
Media Client and the aspect ratio conversion mode setting is set to apply letterbox
bars. If this happens, it results in double-boxing. In this case, if you know the clip
is destined for such a SD output, you can set the widescreen clip’s attribute to
standard screen so that no aspect ratio conversion takes place on the SD playout.
• The K2 Media Client 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 Media
Client System Guide.
