1.9.3 VIDEO CODECS & BITRATES
The EVS XT[2] server uses an intra-frame video encoding technique.
The XT[2] server supports natively the following video codecs:
Codec SD HD Code Protection
MJPEG √ √ No
DVCPro 50 √ - Code 9
IMX √ - No
Intra-frame MPEG-2 - √ No
Avid DNxHD® - √ Code 5
Apple ProRes 422 - √ Code 6
Apple ProRes 422 HQ - √ Code 6
Apple ProRes 422 LT - √ Code 6
DVCPro HD - √ Code 8
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 MJPEG 30Mbps for standard definition and MJPEG
100Mbps for high definition.
The code-protected codecs are solely available when the corresponding code is
valid.
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.
