Does VelocityHD Support Uncompressed or Compressed Video?
Both. HD storage requirements are huge, but not every application needs to be fully uncompressed. VelocityHD offers the flexibility to balance storage space and bandwidth with the quality requirements for your particular application. Recording and playback can be done in 8-bit or 10-bit uncompressed, or using our online-quality LWC-1 compression format (intraframe compression with its roots in wavelet technology). Compressed and uncompressed footage can be mixed in real-time without affecting performance. (Note that dual-stream real-time playback of two uncompressed streams requires the SCSI-7000 dual-channel SCSI daughtercard). VelocityHD’s compression supports variable compression, not just particular fixed rates, and supports compression ranges from roughly 1.5:1 to 7:1 (8-bit LWC-1 compression, relative to 8-bit uncompressed YUV), or roughly 2:1 to 9:1 (10-bit LWC-1 compression, relative to 10-bit uncompressed). When compressing video, Velocity uses Feed Forward Entropy Calculation
