1.4.1 Compression Format
The HMP-1801 utilizes the JPEG2000 compression algorithm for high-quality video. This technique uses wavelet
transforms rather than the discrete cosine transforms used for JPEG and MPEG compression. JPEG2000 does not
use temporal or interframe compression. Each frame is processed individually.
The artifacts of JPEG2000 encoding are less visible than those of conventional MPEG, appearing as a gradual
blurring or smoothing of the image rather than the blocking or mosquito noise encountered in MPEG images, and
JPEG2000 supports mode encode/decode cycles than other formats. Furthermore, the images can undergo a higher
compression before artifacts appear. The HMP-1801 import tool will encode video at 100Mbps for HD video and
25Mbps for SD contents.
The HMP-1801 allows the export and import of compressed data files, and it is convenient to use this approach when
exchanging video essences between cards. The HMP-1801 can import these file formats:
•
Sequence or still BMP
•
Sequence or still JPG
•
Sequence or still 24 bit TGA without alpha channel
•
Sequence or still 32 bit TGA with alpha channel
•
Morgan MJ2K compressed AVI
•
QuickTime file with Advanced workflow option
Note: The HMP-1801 will output the original content without applying any filters. It is the responsibility of the artist to
generate a video sequence that is compliant with the SMPTE standards
1.4.2 Flash Memory
Video essences and clip definitions are stored in Compact Flash memory on board the HMP-1801 card. The memory
card is removable, and is physically located as shown in the diagram below. .
•
Since the memory card is not formatted as a standard Windows device, it cannot be replaced by an off-the-shelf
card
