Editing Vertical Sync Pulse Property from Command Line
Learn how to set the Vertical Sync Pulse for a Custom Resolution via the command line.
Command
Resources.Resolutions.Resolution1000.VSyncPulse
Description
The Vertical Sync Pulse identifies the start of each frame of video in the Custom
Resolution.
Note that for
Interlaced Custom Resolutions both odd and even frames will have a Vertical
Sync Pulse .
Example
Resources.Resolutions.Resolution1000.VSyncPulse = 2
Resources.Resolutions.Resolution1000.VSyncPulse = 2
!Done Resources.Resolutions.Resolution1000.VSyncPulse = 2
Default
0
Notes
The valid range of values is 1 to 100.
For a valid Custom Resolution, you must configure this property to a value within the valid
range. To calculate the
Vertical Front Porch , Vertical Sync Pulse and Vertical Back
Porch for an interlaced resolution, double the value of the even field. Interlacing standards
are designed this way in order to present the values in a similar format to Progressive
values.
Interlaced Custom Resolutions require that the Vertical Sync Pulse is twice the even field.
For example, a Vertical Sync Pulse of 10 gives:
Odd field: 5
Even field: 5
In the CORIOdiscover Resolution Editor, the
Pixel Clock is not affected by any changes to
the Vertical Sync Pulse . However, the Vertical Frequency read-only field varies based on
Vertical Sync Pulse changes.
