Video Encoding

Video Encoding – H.264 AVC/H.265 HEVC (MPEG-4 Part 10)
DVI Input Resolutions / Scan Rates	1920x1200 60 Hz 1680x1050 60 Hz 1600x1200 60 Hz 1600x900 60 Hz 1440x900 75, 60 Hz 1400x1050 75, 60 Hz 1360x768 60 Hz 1280x1024 75, 60 Hz 1280x800 85, 75, 60 Hz 1280x768 85, 75, 60 Hz 1152x864 75 Hz 1024x768 85, 75, 60 Hz 800x600p 85, 75, 60 Hz 720x576p 50 Hz 720x480p 60/59.94 Hz 640x480p 85, 75, 60 Hz Note The DVI interface also supports all the SD/HD/3G-SDI Input Resolutions.
SD/HD/3G-SDI Input Resolutions	1920x1080p 60/59.94/50/30/29.97/25/24/23.98 Hz 1920x1080i 60/59.94/50 Hz 1280x720p 60/59.94/50/30/29.97/25 Hz 720x480i 60/59.94 Hz 720x576i 50 Hz *Interlaced shown in fields per second. Note For supported video encoding resolutions, see Supported H.264 Video Encoding Input and Downscale Resolutions.
Video Bitrates (H.264)	SD/HD from 32 kbps to 25 Mbps
Video Bitrates (HEVC)	SD/HD from 32 kbps to 15 Mbps
Rate Control	Variable (VBR) Constant bit rate (CBR) Note Enabling Partial Image Skip constrains the bitrate generated by the encoder. See “Partial Image Skip” in Video Encoder Settings.
Encoding Latency	Less than 60ms (H.264 encoder at 720p60, 6Mbps) Less than 50ms (HEVC encoder at 720p60, 6 Mbps) Note Encoding latency refers to the time delay between capture of a frame and the instant when the frame is encoded and ready for transmission.
Compression Standards (H.264)	H.264/AVC (MPEG-4 part 10) ISO/IEC 14496-10 Baseline, Main, and High Profiles Up to Level 4.2 and lower Intermediate Levels I, IP, IBP, and IBBP framing Configurable Group of Picture (GOP) size Configurable frame rate Region of interest coding
Compression Standards (HEVC, with supported hardware)	H.265/HEVC ISO/IEC 23008-2 Up to Level 4.2 and lower Intermediate Levels IP framing Configurable Group of Picture (GOP) size Configurable frame rate Deblocking filter Main Profile Up to Level 4.1 (1080p60 @ 15 Mbps)
Macro-block processing limitation	(H.264 only) The aggregate pixel processing power for all video encoding engines cannot exceed 3 x 1080p60 or 1,468,800 macro-blocks per second.
Video Encoding Limits	Up to 3x1080p60 H.264 Up to 1x1080p60 HEVC
