Grass Valley GV STRATUS Installation v.3.1 - Manual (Page 19)

Proxy Encoder overview
When you transfer a file into the K2 system, it is stored as a high resolution clip. GV STRATUS
Rules Services detect the presence of the clip in the K2 storage. The services check to see if the clip
has associated proxy. If no proxy exists, the services check rules. GV STRATUS rules specify that
all high resolution clips must have proxy, so the Rules Services send a transcode job to a Proxy
Encoder. If there are multiple high resolution clips to be transcoded, the transcode jobs are queued
up sequentially and the next available Proxy Encoder transcodes the job at the top of the queue. The
Proxy Encoder transcodes the high resolution clip to create the proxy clip. The GV STRATUS Proxy
Encoder generates proxy media for high-resolution clips with one video track. Clips with more than
one video track are not supported.
