image. We recommend that wherever possible
for production work you prepare artwork of the
exact size at which it will be used.
Notes on Logos:
• Because the logo properties tab is used to
set up a logo interactively on live video,
its behavior is different from the behavior
of the other tabs. The driver updates
the controls on the logo tab immediately,
without waiting for you to click [Apply].
You will see that [Apply] enabled only
right after you select a different pin spec.
As soon as you make any change to any
logo control, [Apply] becomes disabled
and stays that way until you change to
another pin spec.
• If you set up a logo with video set to one
size, then resize video, the logo is scaled
correspondingly. For example, if the logo
is originally set up for 320x240 video, and
you change to 640x480 video, the logo
displays at twice the size of the original
bitmap. Click the [1X Scale] button to
restore the logo to its unscaled size.

This dialog (figure 17) is the default DirectShow
way for obtaining a user’s settings for the output
format of captured video.
Changes made in this dialog apply to the
currently selected pin only. The settings for the
capture and preview pins are independent; in
applications like GraphEdt or AMCap, both must
be set before both pins are used.
Access to the Pin Properties dialogs is
application-specific. For example, in the AMCap
capture application, access is by two entries in
the Options menu, Video Capture Pin… and Video
Preview Pin…. In GraphEdit, right click on the pin
you wish to set the properties for.
Many applications do not use these dialogs; they
instead have their own built-in ways of setting
these parameters.
