Record Video Options
Description
Note: Additional consideration must be given to the number of drives
that make up the destination volume. A single-drive volume will not
support data rates that exceed 30MB/sec. Although it is permissible, it
is not recommended that you attempt to record to a single-drive volume
if the MDR setting is set to MDR60. This may result in undesirable
degradation of picture quality and may even result in some frames not
being recorded.
Encoding
This selector allows you to chose the form of encoding used when
recording clips. Your choices include QPE (spatial) and ADR (spatial).
Both are a spatial form of encoding motion imagery (meaning they are
frame-based and yield fully-editable content).
QPE is the standard wavelet-base encoding method used by QuVIS
video server products. This setting is most often used under normal
motion-imaging recording conditions.
JPEG2000 is the image encoding method required to author Digital
Cinema compatible content.
ADR is a special version of QPE that incorporates a low data-rate
quality safeguard designed for production applications. ADR boosts low
data rates by increasing the SNR to better preserve simple imagery,
which is ideal for test patterns or other low data-rate high quality
images.
