Video Editing OverviewDr. Khaled Gamal talks about the basics of sound in video editing.

Understanding Audio Gain

Definition

• Audio Gain means the level of sound being inputted.

• It is an important feature of the sound file.

Importance

• Changing audio gain at the beginning of editing is very important.

• This should be done before putting audio clips on the timeline.

Adjustment Methods

• You can change audio gain levels:

  • On the source monitor.

  • Right on the timeline.

Gain Adjustment Options

• Gain can be adjusted for:

  • All audio output on the timeline.

  • Specific audio tracks.

  • Individual audio clips.

Normalization Guidelines

• Normalize all peaks to an average level of -3 or -4 dB before exporting.

• Main sounds (like talking) should be between -6 and -12 dB.

• Background music is usually set at around -30 dB.

Audio Gain Settings

• Standard settings can include:

  • Set Gain to: 0 dB (OK)

  • Adjust Gain by: 0 dB (Cancel)

  • Normalize Max Peak to: 3 dB

  • Normalize All Peaks to: 0 dB

  • Peak Amplitude: -7.7 dB

Understanding Audio Volume

Definition

• Audio Volume means the level of sound being outputted.

• It is different from the original sound characteristics.

Functionality

• Volume is adjusted during sound mixing.

Misconceptions

• Lowering the volume when the audio hits the top of the audio meter does not fix distortion.

Volume Adjustment Techniques

• You can adjust the volume of specific clips or overall tracks using:

  • Clip audio mixer.

  • Track audio mixer panels in the source monitor.

  • Access audio settings by clicking the Audio tab at the top of the software.

Master Volume Adjustment

• Before exporting, change the overall volume using the master slider in the audio track mixer panel on the source monitor.
