Audio Only Changes
Audio only changes are much easier to deal with than picture changes. Unless it is an extensive change, like the replacement of an entire voice-over, we probably won’t charge anything extra.
Deliver the AFF file with only the audio for the change. There is no need to include extra audio although including a portion of the audio next to the add or replacement audio will help confirm its synch.
Generally there is no need for a video file to be included although the imbeded mix down of your session’s audio is useful as a guide track.
