1.9.7 AVID DNXHD ® AND APPLE PRORES 422
INTRODUCTION
EVS XT[2] servers feature a native implementation of the Avid DNxHD® and Apple
ProRes 422 high definition video codecs. This enables native audio and video file
transfers in either direction between the EVS XT[2] servers, and Avid and Apple
post-production tools in High Definition. This document explains the impact of
using Avid DNxHD® and Apple ProRes codecs on XT[2] servers, on the XNet[2]
SDTI network and on the XFile[2] or XF[2] in terms of storage capacity, number of
usable video channels and network transfers.
For details on how to setup a direct connection between an HD XT[2] server and
an Avid or Apple server, please refer to the specific documents
(EVS_AvidTM_integration_v2.09 or EVS_Apple_integration_v.2.00).
VIDEO BITRATE COMPATIBILITY WITH AVID AND APPLE
PRODUCTS
Avid DNxHD® is standardized at specific bitrates according to 2 profiles:
1. Standard profile: 120Mbps in “PAL” (50Hz) and 145Mbps in “NTSC” (59.94Hz)
2. High Level profile: 185Mbps in “PAL” (50Hz) and 220Mbps in “NTSC” (59.94Hz)
Although Avid DNxHD® is standardized at the specific bitrates mentioned here
above, Avid products can seamlessly read DNxHD® files and streams at other
bitrates. DNxHD® pictures at other bitrates than those defined by the 2 official
Avid profiles can also be referred to as “VC-3” as defined in SMPTE 1019.
To allow users to determine the best balance between picture quality, storage
capacity, number of video channels per server, and network speed, EVS XT[2]
servers can generate Avid DNxHD® files and streams at any given bitrate between
20Mbps and 220Mbps. These files and streams should remain compatible with Avid
production tools.
