Vertical
Resolution
Vertical resolution of encoded video.
Horizontal
Resolution
Horizontal resolution of encoded video.
Chroma
Sampling
Use 4:2:0 for applications transmitting to consumer equipment.
Bit Depth
Use 8-bit for AVC applications transmitting to consumer equipment.
Scanning
Mode
Progressive or Interlaced.
Aspect Ratio
Configures display aspect ratio of encoded video.
Fallback
Aspect Ratio
Configures display aspect ratio of encoded video when input is lost.
8.2.1.3 Encoder Video Profile
– HEVC
Codec -
HEVC
Profile
Profile controls stream complexity. Available Profiles is restricted by Chroma
Sampling and Bit Depth above.
Level
Auto
– Encoder selects appropriate Level based on resolution, bitrate etc.
Tier
Main or High Tier. The choice affects bitrate range allowed.
IDR
Frequency
Selects how frequently I frames are upgraded to IDR frames. Value of ‘0’ means no
IDR frames. Value of 4 means every 4
th
I frame is upgraded to IDR frame.
Bitrate
Elementary stream bitrate. Configurable range depends on resolution, tier, latency
mode etc.
GOP Mode
In Dynamic mode encoder alters GOP to optimize VQ.
GOP
Structure
Selects GOP composition. (Latency mode restricts options.)
Max B
Frames
Maximum number of successive B frames.
GOP Size
GOP size. Average distance between I/IDR frames.
Hierarchical
GOP
Enables hierarchical GOP. (Also referred to as Reference B frames.)
LDB
Low Delay B frames.
