Using the video capture card
The Osprey 800 series is a high-definition (HD) video capture card. The card has significant
operational differences from other cards that fall under the standard-definition Osprey card family
including advanced features to accommodate the many input video standards that are part of the
HD experience and to adapt automatically to input signal types dynamically, a common need in the
HD environment. The card has the following controls:
VGA Settings (Osprey 820e only)
Device
Video Proc Amp
Input Detect
Video Decoder
Deinterlace
Crossbar
Watermark
Trace
Loss Of Signal
Performance
Cropping
Diagnostics
Closed Caption
Resource Monitor
The Osprey 800e series includes a special version of Osprey SimulStream that allows you to
“virtualize” the entire feature set of the card. That is, the card can simultaneously feed more than
one capture/encode application or multiple instances of the same application, from the same
controls can be set separately for each capture stream below:
Crop
Logo
Captions
With the Osprey 800 series, all of the above features can be set individually. Each application
receives its own full set of identical Property settings tabs. Another significant operational difference
of the Osprey 800 series and other Osprey cards is that in the Osprey 800e series each stream is
configured separately. As a result, the second and subsequent streams may appear to have
randomly changing defaults.
For example, if you originate Instance 1 of Windows Media® Encoder (WME) rather than from a
previously named and saved settings file, and you configure the encoder for a 720P WME stream
with a watermark (for example, a logo) in the lower-right corner of the screen. When you originate a
second instance of WME, WME adopts the same settings, including the same watermark in the
same position, as the stream created before it. This situation occurs because, in the second instance,
the WME was not started from a saved settings file. Therefore, the WME was forced to assign
default settings, and adopted the most recently configured stream. If, in the second instance, you
need to create different configuration settings, you should modify the settings, save the WME, and
name it something other than in Instance 1 – a unique file with a different name.
