EVS Broadcast Equipment SA – July 2011

TARGET BITRATE RANGE AND DEFAULT VALUES

The target bitrate of the encoded video stream can be set by the user within the

accepted range: 8 to 100Mbps for standard definition, 40 to 250Mbps for high

definition with the exception of Apple ProRes, Avid DNxHD® and DVCPro codecs

working with defined bitrates.

The default values are M-JPEG 30Mbps for standard definition and M-JPEG

100Mbps for high definition.

The code-protected codecs are solely available when the corresponding code is

valid.

CONTENT TRANSFER ENCODING AND FILE HEADER

Up to Multicam 10.01, all codecs used in the EVS Video servers were encoding in

8-bit. From Multicam 10.03, it is possible to perform the encoding process in 8-bit

or 10 bit and to write a 10-bit file on selected codecs.

The following table summarizes the proposed configurations in the XT2+:
