Audio in Video: The Basics

The hierarchy of filmmaking puts visuals at the top of the table, yet every video from the era of silent films to the Bond franchise today, have audio used in different forms. Although it is easily dismissed, audio plays a role in filmmaking unlike any other by augmenting the experience of the audience.

In this blog, we discuss the foundational elements that help to create good audio for video production.

Voice overs (dialogue)

The other way is through Sync Sound – recording sounds and dialogue during filming. Voice overs also require special care in terms of the script and the voiceover artist, it is the starting point of any video production.
