USAGE
The driver software provided with the UFG-05 family frame grabbers is an AVStream
WDM driver compatible with standard capturing applications supporting Microsoft®
DirectShow®. The driver is built for Microsoft® Windows 8, Windows 7, Windows XP
and Windows Vista.
Previewing Video
You may preview the video captured by UFG-05 with applications like
Windows Media
Encoder, VirtualDUB, AmCap, GraphEdit
, etc. The driver has been tested with all
standard DirectShow renderers.
The UFG-05 appears as a single DirectShow Filter (UFG-05 Channel)
under the group
Video Capture Sources in GraphEdit
To gain best picture quality do not set 60 Hz for 50 Hz based signals
Use the
Override
settings in the FG properties dialog if you need a custom format.
Some applications might need reconfiguration as this setting is applied when the graph
is rebuilt.
The SRC, SRC/2, SRC/3, SRC/4 frame rate settings give the best picture quality
because they give a
Frame Locked
stream. When you use them, rebuild the graph each
time the source frame rate changes.
When capturing the PCI bus bandwidth might be the bottleneck of the system especially
if you use a high performance PCI Express graphics card.
UFG-05 series frame grabbers are fully compatible with
Vista Aero
Capturing Video
The UFG-05 driver stores the captured images only as 32-bit RGB bitmaps. In order to
generate compressed stream formats a software tool with a compression codec is
needed.
You can frame lock to every 2nd, 3rd or 4th frame of the original video input to save
PCI bus bandwidth and ensure a smooth video stream output.
When capturing video, the CPU performance or the hard disk storage performance
might be the bottleneck of the system.
