Required settings to use the plug-in
5 Choose Edit > Preferences > Matrox Preview Settings.
¦NoteThe Enable preview option is selected by default. If you want to run
Adobe Premiere at the same time as After Effects, then you must clear this
option before you start Premiere.
6 Click the Setup button.
7 Under Output Size, select the size that you want your composition to be
displayed on your NTSC or PAL video monitor. For example, select
Original to maintain your composition’s original size.
8 Under Render Preview Type, select one of the following options for
previewing the rendering of your composition on your video monitor:
$ Video and alpha Select this to view your composition keyed over a
black background.
$ Alpha only Select this to view only your composition’s grayscale
alpha-key (matte) information.
Remarks
• When you separate fields in your imported video footage, only one video
field will be displayed when you preview the video on your NTSC or PAL
monitor. When you render your final image, however, it will be rendered
correctly.
• You can apply the Broadcast Colors effect to your composition to reduce
luminance or saturation to a safe (legal) level. To do so, select all the layers
in your composition, then choose
Effect > Video > Broadcast Colors.
Choose either
NTSC or PAL according to your system. For more details, see
your Adobe After Effects User Guide.
