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.
Codec 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).
Tile-Part Length Markers
. When checked, specifies that Tile Length Markers will be
used.
End of Packet Header Markers
. When checked, EPH marker segments are generated.
Start of Packet Markers
. When checked, SOP marker segments are generated.
CUDA Memory Limit
. Specifies the CUDA memory limit in MB.
Note:
When the CUDA Memory Limit is set to 0, GPU processing is disabled.
CUDA Tile Limit
. Specifies the CUDA tile limit.
Encoder Queue Size
. Specifies the encoder queue size.
