While creating
videos, the visuals
receive more
importance than the
audio. But audio is
vital for videos and
plays a very
important role in
enhancing the
viewing experience. Acknowledging its
importance, Video Edit Magic provides
you with Audio
tracks on which you
can place audio
files. |
|
| |
| |
Audio Tracks: |
| |
Video Edit Magic has two audio tracks. Whenever you add a video
clip to the Timeline,
its audio is
automatically added to
one of these Audio
Tracks. You can also add
audio files containing
your favorite song, a
background score, or a
voice-over narration. |
|
| |
|
| |
Types of
Audio you can add to the
audio tracks: |
|
| |
|
Narration
means using
a recorded
voice to
explain
what's on
the video.
Audio
narration
can help you
share your
experience,
in your own
words.
To use the
Audio
Narration
tool in
Video Edit
Magic, you
must have a
microphone
connected to
your PC. |
|
To add
Audio Narration: |
|
|
1. |
Add the
video clip
to the
Timeline. |
|
|
2. |
If you don’t
want to
retain the
original
audio track,
click on the
audio track
and hit the
delete
button. |
|
|
3. |
Click on
Narration
from under
the Tools
menu. Click
on
Options
to change
the Audio
Device and
the Audio
Compressor
used for
recording. |
|
|
4. |
Position the
Seek Slider
on the
Timeline
where you
want to
start
narrating
and click
Record. |
|
| |
|
|
| |
 |
|
| |
|
|
| 5. |
Click on
Stop
when you are done. A audio file
will be
created on
the audio
track with
your
recorded
narration. |
|
| |
|
Background
Music
can be used
to create a mood. Audio files
in popular
file formats
like MP3 and
WMA can be
placed on either of
the two audio
tracks. You
can insert
your
favorite
songs as background
music to
your videos. |

Volume Graph: |
|
| |
A volume graph is under
both audio tracks. The volume graphs remain
hidden by default. To
view them,
click the small white
plus sign beside every audio track.
Click it again to hide
the volume graph. |

|
|
| |
Volume graphs let us
adjust audio visually. A volume
graph is similar to a
rubber band which can
be stretched to change
the volume levels. When
you click on this rubber
band, a little dot
appears. You can then
click and drag this dot
up and down to adjust
the volume level. If you
want to get rid of a
dot, simply right click
on it. |
|
| |
|
|
| |
You can also move the
entire graph together to
specify a new volume
level, while retaining
the variations you have
specified. To move the
entire graph, press the
CTRL key and click on
any dot. Now, while
keeping the key pressed,
drag the dot upwards or
downwards. The entire
graph will move with the
dot. |
|
| |
|
|
| |
You can change the
volume at any point to
between 0 and 400% of
the original volume. |
|
| |
|
|
| |
Types of Audio
Effects you can create: |
|
| |
Mixing:
You can choose to have
both narration and
background music played
simultaneously. To
do so, place the
background music on the
second audio track.
Now, mix the narration
and music by using the
volume graphs. For
instance, you can lower
the volume of the music
when the narration
begins. |
|

Audio Cross Fades:
A cross fade is a
smooth transition
between two audio files.
One audio source
gradually becomes
quieter while the other
becomes louder. During
a scene change, you can
insert a new music piece
without it sounding out
of place or breaking the
flow of the story.
Applying an audio cross
fade is very easy with
the volume graphs.
To create audio
cross-fade effect, you
must have audio sources
on both audio tracks,
positioned so that they
overlap. |

|

The screen-shots show a
sample audio cross-fade
between Audio 1 and
Audio 2 for a period of
approximately 2 seconds.
The audio in Audio 1
will decrease in volume
(from 100% to 0%) until
it reaches silence.
At the same time, the
audio in Audio 2 will
increase in volume until
it reaches 100%.
This is an audio
cross-fade. |

Doppler Effect:
Let’s start with an
example. A fire engine
siren will ring at a
higher than its
stationary pitch, slide
down as it passes, and
continue to lower than
its stationary pitch as
it recedes from an
observer. If the vehicle
approached the observer
directly the pitch would
remain constant. But to
avoid hitting the
observer the vehicle has
to take a radial route.
This radial movement
causes Doppler Effect,
which is basically a
variation in the pitch.
Doppler effect is a
change in frequency and
wavelength of a sound
wave, resulting either
due to motion of the
source or the observer. Audio Points
that can be seen in the
screenshot above need to
be adjusted to control
the sound waves and get
a Doppler effect. Audio
points when arranged in
a crest and trough
pattern, what you get is
a Doppler Effect. |

Sounds and silences have
their role to play in
video productions. Orchestrate them in your
creations using Video
Edit Magic. Blend audio
with your videos and you
will see that your
videos reach new
heights. |
