HEVC
Bit Rate (in kbps) . Specifies the target bit rate (512 - 50,000).
HEVC H/W
HEVC H/W is available only when hosted on a platform with the required hardware.
Quality . Specifies video quality profile: Main | Main 10 | Main 10 4:2:2.
Bit Rate (in kbps) . Specifies the target bit rate (512 - 50,000).
IMX
Quality . Specifies video quality profile: 30 Mbps | 40 Mbps | 50 Mbps.
JPEG2000 Lossless (Comprimato)
The Comprimato JPEG2000 Lossless codec encodes the input video into one output
video file in JPEG2000 format, using the JPEG2000 codec in lossless mode.
Comprimato-based ISO/ITU still image compression provides a fast and flexible
solution for high-quality, wavelet-based compression.
JPEG 2000 is an intra-frame HD video codec specified by ISO/IEC 15444-1. It uses
wavelet transformations to compress the image which results in high quality images in
both lossy and lossless modes. JPEG 2000 offers higher compression ratios over
standard JPEG video. It offers resolution, color, quality and position progression
scalability, and also supports 4:2:2 and 4:4:4 chroma subsampling methods.
Configuration Settings
Pixel Format . Specifies the color space, chroma subsampling, and bit depth to use for
encoding.
- RGB 4:4:4 8 bit or 10 bit
- YUV 4:2:2 10 bit
- YUV 4:2:2 8 bit
Tile Partition Width . Specifies the tile partition width in pixels.
Tile Partition Height . Specifies the tile partition height in pixels.
Precinct Width and Height . Specifies the precinct size.
Code-block Width and Height . Specifies the height and width (in pixels) of a code
block to process.
Packet Progression Order . Specifies the order of packet progression.
Decomposition Levels . Specifies the maximum number of discrete wavelet transform
levels, or stages, to use (also known as Discrete Wavelet Transformation resolution).
