Setting display options for recording videos
Before starting to record videos, you should configure Epiphan
video capture application display settings.
Note: Most video codecs require setting the display format to
RGB 24 bits per pixel.
The following display options change how the video capture
application records video files.
For more information about display options, see “Configuring
display options” on page 71 .
Selecting a Windows video codec
The video capture application automatically finds all of the video
codecs installed on the video capture workstation. Unless you
have already installed a high-speed codec, most of the codecs that
the video capture application finds may be too slow or have poor
compression. If a codec is too slow, the video recording frame rate
may be too low to produce a good quality video without
compromising the performance of the video capture workstation.
If a video codec has poor compression, the recorded *.avi files
could become very large.
Display
Format
The video capture application records video files
with the same color depth as the display format.
Usually you need to set the display format to RGB
24 bits per pixel before recording videos.
Limit
frame
rate to
If you limit the frame rate, the video capture
application records videos at the same rate as the
limited frame rate. If the limited frame rate is higher
than the frame rate of the Frame Grabber, the video
capture application records videos at the frame rate
of the Frame Grabber.
