Bouncing to a New Movie
When you have finished your final mix and syn-
chronized your audio events to the movie, you
can use the Pro Tools Bounce to QuickTime
Movie command (Pro Tools 6.1 and higher) or
Bounce to Movie command (Pro Tools 6.0.x and
lower) to compile a new QuickTime movie with
the bounced audio embedded in the QuickTime
movie file as the soundtrack. As a QuickTime
file, the new movie is supported by all software
applications that support QuickTime video.
To create a new QuickTime movie with bounced
audio embedded as the soundtrack:
1 Adjust track output levels and finalize your
mix. Any inserts and effects settings that are ac-
tive on tracks will be permanently written to the
bounced tracks.
2 Make sure that what you are hearing is what
you want to bounce, and that your “bounce-to-
disk” output assignments correspond to the out-
puts you are listening to.
3 If you want to bounce the entire session, press
the Return to Zero button on the Transport to go
to the beginning of the session. The new movie
file will include all the video and audio material
in the session, even if the duration of the video
material is longer than the audio or vice versa. If
you only want to bounce a portion of a session,
open the Edit window and select the section
that you want to include in the bounce.
4 Choose Movie > Bounce to QuickTime Movie
(Pro Tools 6.1 and higher) or Bounce to Movie
(Pro Tools 6.0.x and lower).
5 Select the file format for the movie audio.
Choose Stereo to retain the stereo mix of the ses-
sion for the movie audio. Choose Mix-to-Mono
to combine the left and right channel output of
the session to a mono movie soundtrack.
6 Select the resolution for the movie audio. Red
Book audio CDs are always 16-bit, while some
multimedia presentations and CD-ROMs use 8-
bit resolution. You cannot create a QuickTime
movie with 24-bit audio; audio from 24-bit ses-
sions is converted to 16-bit or 8-bit audio, de-
pending on what you choose.
7 If you intend to convert the session to 8-bit
resolution for use in multimedia, use the
Squeezer option (click the Convert after Bounce
option, then the Settings button to access this
feature) to improve the fidelity of the converted
8-bit audio. This option uses a proprietary DSP
algorithm that preprocesses the audio using
compression, limiting and gating before con-
verting to 8-bit resolution. This option is recom-
mended for optimal results for 8-bit audio.
Bounce dialog
Mix-to-Mono may result in clipping if you
do not leave 6 dB of headroom in the mix.
