Pro Tools Reference Guide584
To spot audio to a movie:
1 Click the Grid button at the upper left corner
of the Edit window. This ensures that the audio
will align to a frame boundary.
2 Set your Grid Value to Time Code using the
pop-up menu.
3 Choose a desirable Grid unit setting. Note that
you can set the grid units independently of the
Main Time Scale.
4 Using the Selector, place the insertion cursor
at a location in the movie. If you want, use the
Nudge Value pop-up to set the nudge units to
frames. You can then use the plus and minus
keys on the alpha keyboard to nudge the inser-
tion point frame by frame.
5 While pressing the Control key, drag a region
from the Regions List to the appropriate track.
Pro Tools will automatically spot the region to
the same time location as the cursor.
Importing QuickTime Audio
(and Other Compressed Video
Files)
Pro Tools allows you to import audio directly
from a QuickTime movie. You can import audio
from a movie currently loaded into a session, or
from a different movie. The procedure is the
same for both.
Pro Tools supports the following compressed
QuickTime file formats:
◆ MP3
◆ QDesign
◆ uLaw 2:1
◆ aLaw 2:1
◆ Intel ADPCM
◆ Microsoft ADPCM
◆ IMA 4:1
◆ 32-bit floating point
◆ 64-bit floating point
◆ 16-bit Big Endian
◆ 16-bit Little Endian
◆ MACE 6:1
◆ MACE 3:1
QuickTime files can be imported into sessions
using either Import Audio from Other Movie or
Import Audio from Current Movie menu com-
mands.
Sample Rate Conversion Quality
If you import QuickTime audio that was not
originally recorded at the session’s sample rate,
the sample rate is converted to match the audio
to your session. Pro Tools allows you to choose
the quality of the sample rate conversion by
means of the Conversion Quality setting in the
Editing Preferences. The higher the quality of
sample rate conversion that you choose, the
longer it takes to perform the sample rate con-
version.
The five conversion settings range from Low to
Tweak Head. The Low setting provides results
that are considerably better than the Macin-
tosh’s built-in sample rate conversion. For most
applications, the Better setting will yield excel-
lent results.
To spot elements directly to locations in the
movie, use the technique described above. In
this scenario, Auto Spot mode is not recom-
mended, since it uses incoming MTC for lo-
cation information.
