Note: The data rates shown here are approximate. For purposes of determining hard disk
capacity for capture, carefully research the details of the format you are using.

Uncompressed High Definition Formats

HD requires extremely high data rates (around 1.4 Gbps). There are no camcorder formats
currently available for recording uncompressed HD video. High-capacity, general-purpose
digital tape formats like D-6 can be used in combination with camera heads and digital
telecine machines capable of outputting uncompressed RGB and component HD video
data. High-speed disk arrays can also be used to record uncompressed HD video.
