Chapter 4

The second track contains a commentary which begins in the

middle of the piece of music and does not end until some time

after the music has ended. You can then reduce the volume

of the music for the complete duration of the commentary by

clicking on Correction, selecting the music track, and reducing

the volume by means of the right-hand control. The origi-

nal sound, which was muted for the duration of the piece of

music, must now also be switched off for the remainder of the

commentary.

For this purpose, create a new piece of music: silence. Create

a generous length. Insert it after the piece of music, and trim

it using the Range button up to the point in the video at which

the commentary ends. If you cannot ﬁnd the point in the video

easily from the material, calculate the correct position if neces-

sary.

The volume control for the track in which the audio sample

is activated is of course not selectable under Correction, as

changes affecting the volume must be made by means of the

Volume button.

(19) Click on one of these menu symbols to jump from this

menu directly to the Audio Record, Edit menu and to the main

menu.

4.14 Shutdown (OFF)

This button turns off the system. Clicking it does exactly the

same as pushing the manual switch on the front. The power-

down procedure saves all settings, so that after turning on the

machine later you can continue your project where you left off.

The project is saved and then the system is shut down. You

can then turn on the machine only by using the manual switch

on the front of the unit. We warn against shutting down the

machine by pulling the power plug or cutting power to the

machine. You should always turn off your system with the ‘Off’

button or the front switch. Data loss may otherwise occur.

all sound tracks. Click onto ‘Range’, conﬁrm with ‘OK’ and

select the IN and OUT points from the already familiar Range

menu. The Envelope helps you to do this. You can (de)activate

it using the speaker symbol. Click on ‘OK’ in the Range menu.

This creates the sample and adds it just after the currently

activated/marked sample in the Record/Edit menu.

(17) Direct volume control

Use the Volume button to adjust the volume of the active video

scene. You can reduce the volume of the scene (negative dB

value), mute it (slider fully to the left), or increase the volume

(positive values up to 30 dB). Use this control for example to

prevent a soft sound from being drowned by another sound

which is too loud (e.g. piece of music on the background

track).

A change in volume is shown in the light-blue bar which forms

the background to the audio samples. If the volume is re-

duced, the bar at the lower edge of the audio sample is also

displaced. The longer the audio sample, the more clearly of

course the characteristic is displayed.

(18) Indirect volume control

To emphasize a particular audio sample by reducing the

volume of adjacent tracks, use the Correction function. Click

on the sample to be emphasized, which is then highlighted in

blue.

The Correction button modiﬁes the volume of an audio sample

for the complete duration of another audio sample. The change

is shown by the blue bar in the audio sample.

Once you have selected an audio sample (e.g. music) in one

of its sound tracks (e.g. music sound track), you can then

click on the Correction button. A list is displayed containing

all six sound tracks. From this list, select the sound track (e.g.

original sound track) in which you wish to modify the volume of

an audio sample (e.g. vocals). Then slide the control located on

the right of it to the left or right (to reduce or increase the vol-

ume respectively). This changes the sound in the track which

you previously selected (under Correction) for the complete

duration of the audio sample activated in another track.

By way of explanation, consider the following example. You

have assigned audio to three tracks. The ﬁrst contains the

original sound, which extends throughout the storyboard.

The third track contains a piece of music which begins while

the original sound is running and which ends during a further

original sound. Select this piece of music. Then click on the

Correction button to call up a list of all sound tracks. From this

list, select the original sound track and reduce the volume by

means of the button adjacent to Correction until it is muted.

You now have no original sound for the complete duration of

the piece of music. You can now hear the music at this point

of the video without being disturbed by the original sound.
