Playout on K2 Summit Production Client
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 Production Client
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. Refer to
“Aspect ratio conversions on
HD K2 client” on page 262 .
The K2 Summit Production Client supports mixed clips with uncompressed and
compressed (PCM, AC3, and Dolby) audio on the same timeline.
