Video Edit Magic 4.47

Useful Audio Effects

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 Track highlighting Volume Variations

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.

Timeline showing the Audio Cross-fade effect

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.
