Film Editing Video or SoundEditing includes work on both the visual and audio aspects of a production; one of these will have to take priority during any editing session. For instance, the sound has priority when filming important dialogue.

The camera would need to mainly focus on the speaker, but would need to do cutaway shots to film reactions or other parts of the scene or view different angles to keep the scene changing and audience interesting. But the dialogue would remain unbroken, even when editing the images.

Sometimes dialogue is too long and needs to be edited down. The most significant parts are often edited together. Sometimes a conversation is filmed in two different areas, but needs to be edited as if it was shot in one. This editing would cut between the two pieces of dialogue to link them together.

Sometimes sound is priority and sometimes the images are priority, but the editing must always support whatever has been established as primary.
