• Linear PCM Settings: These options are only available when you choose Linear PCM
from the Format pop-up menu.
• Sample size: Choose a bit depth for your audio samples. For most situations, 16-bit
audio is the minimum bit depth you should choose, but sometimes 8-bit audio is
useful when creating small, low-quality movies for the web. If you choose 32-bit, you
have the option of using integer or floating-point values. You can also choose 64-bit,
but only if the Floating Point checkbox is selected.
• Little Endian: This refers to the way audio data bytes are ordered. Little endian byte
ordering is used when creating Windows-compatible WAVE files. Big endian order
is used when creating AIFF files.
• Floating Point: This option affects how the bits of each sample are used to represent
audio amplitudes. Floating point is available with 32-bit audio, and required when
using 64-bit audio.
• Unsigned: This option is automatically turned on when exporting 8-bit WAVE files.
Internet Streaming Settings
If you’re outputting QuickTime files for streaming over the Internet, there are three format
options in the Movie Settings dialog.
Important: If you are not exporting a QuickTime movie for web distribution, make sure
you deselect the Prepare for Internet Streaming checkbox in the Movie Settings dialog.
• Fast Start: The QuickTime movie is downloaded the same way as any other graphics
or media file. Once enough of the movie has downloaded, the movie begins to play
automatically.
• Fast Start—Compressed Header: This works the same way as Fast Start, except that the
header information is compressed, so the movie takes up less disk space. The person
downloading the file must have QuickTime 3.0 or later.
• Hinted Streaming: If the movie will be hosted with QuickTime Streaming Server software,
it begins playing within a few seconds after access. “Hinting” a QuickTime movie is the
process of defining how it’s divided into streamable pieces and storing that information
as a special track within your QuickTime file.
If you’re not sure you want this option or don’t want to do this now, you can do this
later by importing your QuickTime file into QuickTime Player Pro and applying hinting
there.
