Performance for Production Professionals

High-quality 4:2:2 Component Digital Recording

With an extremely mild, perceptually lossless 3:3:1 compression ratio and a data rate of 50 Mbps, D-9 can capture even the most challenging picture in all its splendor without compression artifacts such as pixel noise, edge defects, blockiness and multi-generation degradation produced when 5:1 compression systems record difficult pictures. D-9's low compression intra-frame processing ensures beautiful high resolution pictures when cascading compression CODEC’s such as MPEG-2 mastering for DVD.

Highly efficient 50 Mbps intra-frame encoding has emerged as the standard reference for mainstream television production. To maintain superb picture quality from acquisition to production, all D-9 products use a data rate of 50 Mbps.

In 1998, a joint SMPTE/EBU task force test results show that D-9 provides;

• Quality identical to that produced by Digital Betacam

• Superior quality to that found in Beta-SP

• Better quality to 50 Mbps MPEG-2 1 frame only

Superior Image Reproduction

NORMAL

LOLUX 0.75 Lux

When activated, the LOLUX mode increases sensitivity with almost no increase in noise. LOLUX lets you shoot in low light conditions, so you can capture high-quality video footage with excellent color balance at just 0.75 lux illumination.

600% Wide Dynamic Range

Multi-stream parallel digital pipeline processing at 40 MHz creates an ultra-smooth gamma curve calculated using a true log scale algorithm. The result is a dynamic range of 600% to accurately reproduce fine details and colors in areas of both shadows and highlights.
