Working with Formats
•
L = Letterbox (linear scale to fit one axis, center w/black bars in other)
•
Z = Zoom (blow- up to fill destination aperture with cropping, or LI )
•
S = Scope (under-sample content horizontally)
•
W = Widescreen (over-sample content horizontally)
•
J = Justify (non- linear horizontal expand – more near edges)
•
K = Keep safe (shrink to avoid cropping – provide safe title)
•
P = Pan & Scan (truncate)
•
M = Mirror (horizontally – rear projection)
Other Modifiers
•
I = Inverse (undo operator; for example, S = Scope and SI = Inverse Scope)
•
O = Orthogonally (rotate operator effect or aperture 90 degrees)
•
X = Wildcard or special
Using legacy format names
You can configure the generator to display names using conventions from older generator
models.
Important: Configuring the generator to use legacy names will delete all user-defined
video formats currently stored in the generator. Therefore, it is important to back up the user
data files from the generator to disk and then restore them back to the generator. VGM can
be used to backup the generator.
To display legacy format names:
1. Turn the generator off.
2. Hold down the
G
key, and then power on the generator.
The following message appears on the front panel LCD.
3. Release the
G
key. This setting is retained throughout subsequent power cycles.
To re-assert the default format names you must reinitialize the generator:
1. Turn the generator off.
2. Hold down the
ACS
and
DSS
keys and then power on the generator.
