Corel Painter 439
frame, this compressor is lossless.
For most Corel Painter
animations, this compressor is a
good choice.
• Cinepak®—this method produces
acceptable motion and image
quality at remarkably small file
sizes. It is the preferred format for
CD-ROM delivery and transfer
across the Internet. Cinepak can
take a long time to compress, and
it can be difficult to find the best
compression settings for certain
image types and frame rates.
• Graphics—this method is limited
to 256 colors. It compresses the file
at a greater ratio than the
Animation compressor, but does
not play as quickly.
• None—with this setting, no
compression is used, so the images
retain all of their quality. With a
large frame size, some computers
might not be fast enough to play at
a high frame rate.
• Photo-JPEG—JPEG is an
international standard for image
compression. It allows high
compression ratios while
maintaining excellent image
quality. However, it does not play
at high rates.
• Video—this method is designed
for recording and playing back
digitized video at high rates.
Because of the spatial compression
method it uses, the Video
compressor does not provide great
results for images with large areas
of continuous tone, such as those
in most animations.
The compression ratio is inversely
proportional to image quality. The
Quality slider allows you to set an
optimum level between the amount of
compression and image quality. For
most work in Corel Painter, you’ll
want Quality set to High.
Frames per second controls the speed
of display. Specify the number of
frames you want displayed per second.
Key frames are used in temporal
compression methods. Each key frame
is stored in its entirety. The next set of
frames—up to the next key—are
saved only as changes. With some
compression methods, you can specify
the frequency of key frames with the
Key Frame Every option.
With some compression methods, you
can also limit the speed of data
transmission with the Limit Data Rate
option. The data rate limit overrides
the Quality setting, if necessary, to
keep the compressed movie within the
set limit.
