Record Video Options Description
sequence (e.g. busy crowd scene) that the Maximum Data Rate setting
may trigger the server to invoke a record failsafe mechanism that will
temporarily reduce the image quality in order to prevent data clipping or
in extreme cases dropped frames.
Colorspace
The Colorspace control is used to define the colorspace of the source
input video stream. The Acuity has the ability to convert the native
colorspace of the input source to native colorspace of the record
format.
All QPE-encoded formats are stored in YUV. The source colorspace
can either be YUV or RGB. In the case that source content colorspace
is RGB, it must be specified so that the Acuity can properly convert it to
the stored colorspace. Separate
Output Colorspace options are
available to change the colorspace during playback.
All JPEG2000-encoded formats are stored in XYZ. If the source content
colorspace is not CAP XYZ it can be automatically converted from
YUV
(709) or RGB (709) real-time during record in order to comply with
Digital Cinema requirements. Separate Output Colorspace options
are available to change the colorspace during playback.
Note: If the source content colorspace is not XYZ, you must specify the
colorspace to ensure proper color-rotation during record.
IMPORTANT! JPEG2000 Real-time Record capability is a licensed
feature module and requires specific hardware components.
Destination
Select the destination (volume and directory) where recorded assets
will be stored. A volume, in QuVIS terminology, is a set of one (1) or
more hard drives that effectively serves as a single storage device.
Note:
There may be limit to your ability to record high-quality, high
frame rate material depending upon the number of disks that make up
the destination volume. The minimum number of drives in a volume is
generally determined by the
Maximum Data Rate setting. General
guidelines are as follows:
MDR30 = 2-drive volume
MDR60 = 2-drive volume
QuVIS Media Format
The QuVIS Media Format (QMF) is a compatibility switch that identifies
different QuVIS file format standards.
Select QMF1 if the recorded media file is expected to playback on a
version 1.x QuBit product. Select QMF2 if the recorded media file
needs to be backward compatible with the QuBit 2.x product line (QuBit
ST, EL and DS running QSR 2.3 or higher). QMF3 is the media format
used for DCI JPEG2000 content and is currently only supported on the
appropriately configured QuVIS Acuity.
For additional information, see the QuVIS Media Format (QMF) in
Chapter 3.
Note: Not all hardware configurations will support record or playback of
QMF1 and/or QMF3 content.
Maximum Data Rate
Maximum Data Rate (MDR) is used to set the upper data rate limit
when recording. Legacy 1.x QuBits (QMF1) only support an MDR of
30MB/sec. For additional information, see the
Maximum Data Rate
(MDR) section in Chapter 3.
