Video scaling considerations
Video scaling considerations
Take the following into consideration when working with the video scaling features
of the K2 Media Client.
• For the highest video quality, select a video output format that eliminates the need
for up or down conversion. This requires that you know how the source video was
encoded. For example, if an imported clip was encoded at 1920x1080i, set the
video output format to the same resolution.
• Some video output connectors become inactive depending on the video output
format selected.
• 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.
• The K2 Media Client can play clips with different aspect ratio attributes in a single
playlist.
