Exporting a Movie as an AVI
Movie (Windows)
If you are using a Windows system,
you can export your movie as an AVI
movie.
AVI supports several compression
schemes. The following descriptions
should help you choose one; however,
you’ll probably want to experiment
with different compressors and
settings to identify the best settings for
your work. You may also have
additional compression methods
available.
• Cinepak 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 takes a long
time to compress, and it can be
difficult to find the best
compression settings for certain
image types and frame rates.
• Indeo® Video R3.2 is capable of
full-motion playback on systems
with a hardware compression
accelerator.
• Microsoft Video 1 is designed for
recording and playing back
digitized video at high rates.
• Full Frames (Uncompressed) uses
no compression, 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. This is the
preferred format for transferring
Corel Painter movies to
AVI-editing applications.
The compression ratio is inversely
proportional to image quality. The
Compression Quality slider allows
you to set an optimum level between
the amount of compression and image
quality.
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 Data Rate
option. The data rate limit overrides
the Quality setting, if necessary, to
keep the compressed movie within the
set limit.
To export a Corel Painter movie as
an AVI movie:
1 Choose File menu > Save As.
2 In the Save Movie dialog box,
enable the Save Movie as AVI
option, and specify the number of
frames per second.
3 In the Enter Movie Name dialog
box, choose a location, enter a
name for the file, and click Save.
4 In the Video Compression dialog
box, choose a compression method
from the Compressor pop-up
menu.
5 Specify the options you want.
For some compression methods,
you can press Configure to specify
additional options.
