Working With Graphic Overlays in a Playlist
When WebView transfers an overlay image file to the Mantis, it
converts the file to a standard 24-bit format and automatically
determines the correct image size for the selected output standard,
for example 720 x 480 for NTSC. The Mantis stores the original
image and uses it as the thumbnail that is displayed in the various
WebView editing windows.

Image Resolution
The Mantis conversion of the graphic image does not change the
image resolution.
An alternative to the auto-formatting performed by the Mantis is
to create the image and convert it to the 24-bit file mentioned
above before transferring into the Mantis.
