Description
Click on this button to select an image format file that matches the
material you wish to record (a format file defines the height, width, and
frame rate of a recorded signal). The popup menu allows you to sort
the list of formats by type. More information can be found in the
QuVIS
Image Format Files
section.
Image Format
Select the appropriate Input Source according to the input format.
Serial Digital Input (SDI) – This option is used to record either a
Standard Definition or High Definition serial digital input signal.
Input Source
Analog – This input is used to record an Analog Component Video
signal (YUV/YprPb).
Set the Image Quality (SNR) setting for recorded material. The typical
setting used in a production environment ranges from 51 – 63dB. The
higher the number the higher the quality and larger the data set.
The Image Quality settings used to record DCI JPEG2000 content
(VSP version 9 hardware and JPEG2000 Real-time Record Module
required) are presented as a Low, Medium, or High value. These
three settings (used only for DCI JPEG2000 record setup) are roughly
equal to 48dB, 54dB, and 60dB respectively.
IMPORTANT! The image quality setting defines the minimum quality
level that will be preserved during the record process. There are two
aspects of image quality that must be considered when making the
value selection:
Image Quality
Source Image Quality – If the source image quality is lower than
selected record setting the server will not enhance the source image
quality but may in fact be adding unnecessary data to the recorded
image stream.
Maximum Data Rate – If the selected Image Quality setting is set to
high value there is a chance when recording a complex image
