USING THE TIMESTRETCH FUNCTION
There are several ways in which the timestretch function may be used.
The most obvious way is to mark the region or select the cue you want to affect using the
green IN/OUT keys, select the preset you think is appropriate, set a STRETCH AMOUNT
percentage (either using the DATA +/- keys or by typing in a value from the numeric
keypad) and press the flashing EXECUTE key. Whether you choose to give the new cue a
name more suitable to your purposes is up to you. However, this method is rather hit and
miss and may require repeated attempts to get the right stretch amounts.
Another way and one that may be more intuitive and useful is to use the STRETCH OUT
key on F5/F6. This method is good for setting the stretch amount relative to some other
reference point in the project. For example, you may want a voice over on track 1 to
overlap a music cue on tracks 2 and 3 for a dissolve into a new scene. Alternatively, you
may want to get rid of an overlap so that the voice over is not obscured by the music on
tracks 2 and 3. You may also wish to use the timestretch process to fill a gap on a track.
You could, of course, try to guess (or even calculate) the percentage of stretch required by
entering a value in the STRETCH AMOUNT field but an easier and more ‘tactile’ approach
is to use the STRETCH OUT key. Operation would be as follows:
Let’s imagine you have this situation displayed on the VGA monitor and you want to
stretch CUE A to overlap it with MUSIC 1 L/R:
CUE A
MUSIC 1 L
MUSIC 1 R
TR 1
TR 2
Tr 3
First, put Tr 1 into EDIT. Now, either mark the IN/OUT specifically or use SELECT CUE to
select CUE A. Now jog so that the NOW time is slightly into the MUSIC 1 L/R cues:
CUE A
MUSIC 1 L
MUSIC 1 R
NOW
Now press STRETCH OUT in the TIMESTRETCH page. This will set the stretch percentage
accordingly (in this case, about 150%). Now press the flashing EXECUTE key. CUE A will
be stretched and the end result will be this:
CUE A
MUSIC 1 L
MUSIC 1 R
NOW
You have your overlap and you could use EDIT CUE to set a crossfade.
