Each frame in a frame stack can have one layer. For example, if you add an item from the image portfolio

onto a frame, Corel Painter places the image on a layer. You can move the image around the layer. However,

when you move between frames or close the file, Corel Painter drops all layers — the layer is deleted, and

the layer’s content is flattened onto the background canvas. For more information about working with

layers, see “Layers” on page 513.

The Frame Stacks panel displays thumbnails of several frames. The frame numbers appear under the

thumbnails. The current frame is shown with a red triangle over it.

The number of thumbnails is determined by the layers of onion skin you’ve chosen. By default, QuickTime

and AVI files are opened with two layers of onion skin. For more information about onion skinning, see

“Using onion skinning” on page 829.

Setting movie file sizes

Keep in mind that video and animation can produce huge files. When planning a project, be careful not to

overestimate your available disk space. For an idea of disk requirements, consider this example: Each 640 by

480-pixel, 24-bit color frame is 1.2 MB. At this size, a 12-fps, 30-second animation would consume more

than 400 MB of disk space.

To calculate the disk space required for a frame stack

1 Using pixels as the unit of measurement for width and height, calculate the number of bytes required to

save the frame stack with the following formula:

(Frame Width) × (Frame Height) × (Bytes per Pixel) × (Number of Frames)

2 Divide the product of the formula in step 1 by 1,024 to convert to kilobytes.

Bytes per pixel are determined by the storage type. For example, 24-bit color with an 8-bit alpha

channel uses 4 bytes per pixel. For more information about storage types, see “Creating frame-by-

frame animation” on page 823.

When you save a movie as QuickTime or AVI, the file size can be reduced by compression. For

more information about compression, see “Exporting movies as QuickTime” on page 835 and

“Exporting movies as AVI” on page 837.

Creating frame-by-frame animation

In Corel Painter, you can build animations one frame at a time. Then, when you complete a series of frames,

also known as a frame stack, you can preview them as a movie.

The first step in creating a new animation is to create a movie. You can specify options such as the number

of frames and the frame size. You can also choose how many onion skin layers you want to display. Onion

skinning allows you to see multiple frames at the same time. You can view up to five frames at a time: the
