Clip Frames on Loading
When you select Clip frames on loading, Animation Builder discards all data
outside a bounding box of active key pixels. This selection speeds the loading
of files and reduces both PC and Imagestore memory usage substantially.
When the option is not selected, Animation Builder loads the whole image
irrespective of the key data.
When you bring in images with noisy key signals, the Key Garbage level
(default of 0) should be increased to allow correct key clipping. This is
especially important when key images have come from outside the digital
domain. Experiment with gradually increasing values for this until the frames
are cropped correctly. (0 = black and 255 = white).
Preview
This section controls a variety of preview options that allow you to select
how images and animations are viewed on the PC. These settings have no
effect on the resulting image files.
Selecting an Aspect of anything other than ‘Square’ causes aspect ratio
correction to be applied to images viewed with Animation Builder,
compensating for the difference in pixel aspect ratio between the target
broadcast system and the PC.
To change the background colour over which images are composited, click
on the colour swatch next to the Compositing matte colour and select a new
colour.
Use the Safe zone controls to determine whether you wish the safe zones to
be displayed and control their size and colour. Safe zones are shown
whenever Animation Builder displays the full screen area ie when View
Positioned
is selected from the Edit menu, and when the Edit Position
Graphically option is used from the Animation Options dialog.
Default colour mode
This option determines the colour mode of the animation. For the Imagestore
range of products select .OXA (YUV encoded) and for Intuition select .OXI
(RGB encoded).
