JPEG2000 Lossy (Comprimato)
Supported Containers
- MXF OP1a
- TIFO
Description
The Comprimato JPEG2000 Lossy codec encodes the input video into one output video
file in JPEG2000 format, using the JPEG2000 codec in lossy 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.
