Grass Valley K2 AppCenter v.9.0 - Manual (Page 235)

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.
The K2 Summit/Solo system supports mixed clips with uncompressed and compressed (PCM, AC3,
and Dolby) audio on the same timeline.
