Thumbnail Allows you to choose a thumbnail image to represent the proxy in the Media
window, inside cues and in the Stage window preview. If not specified, a
default icon will be displayed.
Dimension Specifies the size of the image. Applies to still and moving images.
Transparency Allows you to specify whether the image contains transparent areas, as well as
the form of transparency used. Normally, WATCHOUT determines this from
the information in the media file, but when using a proxy, you must specify this
manually. Setting this incorrectly may cause the image to display without trans-
parency or not at all. Applies to still and moving images.
The types of transparency supported by WATCHOUT includes:
• None. The image or video has no alpha channel.
• Straight Alpha. The transparency information affects the alpha channel of
the image only.
• Pre-multiplied with White. The transparency affects both the alpha channel
and the pixels in the image so that the pixels in fully transparent areas are
white. This is often used in material produced for printing purposes.
• Pre-multiplied with Black. The transparency affects both the alpha channel
and the pixels in the image so that the pixels in fully transparent areas are
black. This is often used in material produced for video compositing
purposes.
