DIMENSIONS
Specifies the height and width of the video. It defaults to the same resolution as the
smallest video in the current project. The dimensions combo box holds a variety of
standard settings, or the Set Custom Dimensions box can be set to any desired size.
A few things to remember when setting custom dimensions: height and width must
both be even multiples of four, or DirectShow will refuse to render. If the dimensions
you choose are too large, DirectShow may not have enough memory to render the
video. If the chosen dimensions are a different aspect ratio than the original videos, the
resulting video may look stretched or squashed.
FRAME RATE
Specifies how many frames per second the video contains. The frame rate defaults to
the highest frame rate found in the project’s video clips. (To find a video’s native frame
rate , right-click on the video clip and select Properties.) The Frame Rate combo box
contains a variety of standard frame rates, but if you don’t see the frame rate needed,
check the Set a custom frame rate box and type in a specific frame rate.
