As we approach final edits for both year groups, this may be a good time to remind you to pay special attention to the sound on your film. Remember that audio should peak at 0dB on the FCPX audio meters, and that ‘loudness’ from your computer’s speakers or headphones is just that: it gives only a vague approximation of final sound level output. At the same time, listen carefully to all the audio transition points: make sure there are no ‘sudden changes’ (unless intentional); over-zealous fades; wind-noise coming & going; spurious clicks & pops. Remember also that there are some audio enhancement tools in the Audio section of the Inspector window.
It pays to listen to the whole film with headphones on and with your eyes shut!
