Video
Resolution
Select a video resolution option:
Actual: The actual resolution of the video source is
reported to QuickTime. If, at any point during a
recording session, no signal is detected an error
will occur that could interrupt the recording
session.
Default: If a video signal has not been detected, the
default resolution is reported and the video
remains blank until the signal appears. If the
default resolution does not match the actual
resolution, images are resized to the default
resolution.
Fixed: The same resolution is reported to
QuickTime, regardless of the actual resolution of
the image and whether or not a video signal is
present. All images are scaled to the fixed
resolution.
Default
Frame
Rate
Usually you can set the frame rate in the
QuickTime-compatible video recording
application. If you cannot set the frame rate in the
application, set the default frame rate that the
Epiphan USB device driver sends to QuickTime.
This default frame rate is only used if the
QuickTime video recording application does not
explicitly set the frame rate.
Wide video
mode
The Epiphan USB device driver may not be able to
determine whether the video source is sending a
wide video mode signal. You can select this option
if your video source uses a wide video mode to
make sure that the Epiphan USB device driver
selects a wide video mode.
