If your video involves people talking to camera, your future self may well thank you for remembering to film a wild audio track while you’re there.
When your video is in post-production, you may find you want to edit out irrelevant parts of a rambling interview or cut to a reaction shot or a cutaway. The problem with editing speech in this way is that the ambient sound behind your speaker might change slightly – just enough that the audience will be able to tell you’ve made an edit. The issue is more acute when you’re in a busy marketplace or bar, but it can still be a problem for relatively quiet locations like nature reserves, because of cicada sounds or bird calls.
To create a wild track, film a 30-second audio recording of the location’s ambient sound, without people talking directly at the camera. When you edit, you can lay the audio under the entire scene, so that the ambient sound continues and the flow of the edit remains uninterrupted.
This can also prove useful when you have cutaways or montages that call for ambient sound rather than music. It works especially well with busy traffic spots, marketplaces, rivers and rain scenes.
