Playout of multiple formats
The K2 Summit/Solo system automatically handles material of various types and formats as specified
in the following sections:
Playout on K2 Summit/Solo
For a given frame rate, you can play SD clips of any format back-to-back on the same timeline.
Both 16:9 and 4:3 SD aspect ratio formats can be played on the same timeline. Refer to video codec
description earlier in this section for a list of the supported formats.
On channels with the XDP (HD) license, for similar frame rates (25/50 fps or 29.97/59.95 fps), SD
material transferred or recorded into the K2 Summit/Solo system along with its audio is up-converted
when played on a HD output channel. Likewise, HD material is down-converted along with its audio
when played on an SD output channel. HD and SD clips can be played back-to-back on the same
timeline, and aspect ratio conversion is user configurable.
