AJA XenaHS User Manual — Using Xena With Application Software
Export Plug-in
Use the Export plug-in to export a Photoshop image to the Xena board for serial digital
output. You can find the Xena export function from Photoshop’s
File->Export->XenaExport
menu selection. The Xena export plug-in currently only exports RGB Mode 8 bit images. The
export dialog is shown below.
Windows NT Xena Export Dialog
The only control available in the dialog is Vertical Filtering. When the Vertical Filtering box is
checked, the photoshop image is filtered in the vertical direction before exporting to the Xena
card. Check the box when you want to decrease flicker caused by computer graphics non-
interlace conversion to interlaced video. When checked, Xena performs vertical filtering using
a three line kernel, whereby half of the current line’s pixel values are combined with a quarter
of each of the previous and next line’s pixel values. The boundary conditions (first and last
line) use black for the boundary values.
Usage Notes:
1.
The exported image will be output based on the Format set in the Xena Control Panel.
For example, if the image or selected part of the image is not full size, the image will
then be centered on the output. If the image or selected part of the image to be
exported is larger than full size then only the upper-left most part of the image will be
exported. Photoshop can be used to resize the image accordingly.
2.
If there is a selection via the Marquee tool the plug-in will export only the selected part
of the image. If a non-rectangular selection is made however, the entire bounding
rectangle is exported.
3.
It is useful to use the Actions palette to avoid having the dialog come up for each
export. It can also be useful to assign the action to a function key if the export function
is used often
Using Xena With
Adobe AfterEffects
Xena comes with an Adobe AfterEffects plug-in that allows you to route the AfterEffects
composition window
to the Xena board’s selected output channel. No AfterEffects menus or
windows are changed or altered in any way. As long as the supplied AJA plug-in is put in the
AfterEffects plug-in folder, the composition window will be available at the Xena output. The
plug-in can be found in the “AfterEffects” folder on the Xena Installation CD (as discussed in
the
Installation
topic in the manual you are reading).
For proper operation, the AfterEffects composition window must be sized to match the
resolution as set on the Xena board for output. The following list gives the settings:
•
If 525, set to 720 x 486
•
If 625, set to 720 x 576
•
If 720p, set to 1280 x 720
•
If 1080, set to 1920 x 1080
