Unit 10 - Audio

Audio – The secret to a great picture. Audio can make or break a program. If you concentrate on the audio and make the adjustments discussed below, you will be on your way to creating a great audio track for your video.

Flow:

  1. edit audio to the Timeline
  2. trim the audio
  3. add transitions
  4. add effects
  5. mix

Preimiere audio is clip and track based. Click changes are made in the timeline on the clip and track changes are made using the Audio Mixer. Suggested levels and checkerboarding- Your mix should not exceed 0 db. Digital distortion happens when audio goes louder than 0.

meter

General idea for mixing:

  • Principle Audio between -6 and -12
  • Sound Effect between -12 and -18
  • Background Music around -18
  • Complete mix should be between -3 and -6
  • Total mix -3 to -6 db

    This can fluctuate, it is really up to you.

Here is an example of how you might organize your tracks.

Audio 1 - A2 Main "talking head" audio

Audio 3 - 4 Organic sounds or b-roll audio

Audio 5 - Narrator

Audio 6 - 8 Sound Effects

Audio 9 - 10 Music 01

Audio 11 - 12 Music 02

Split Edits

j cut

J cut - The audio edit occurs before the video.

l edit

L cut - The video edit occurs before the audio.

1. OFF - ignores any of the automation parameters for that track
2. READ - process automation data for all parameters for that track. During playback, each parameter that contains automation data is adjusted to match that data.
3. WRITE - overwrites any existing automation data under the playback cursor, unless that automation lane has been made "Safe During Write." For example: You have manually click some Mute on/off points, and in Write mode, attempt to record some Volume fades. If the playback section occurs where Mute nodes existed, they will be overwritten by whatever status Mute happens to be in at the time playback was started. If you click the "Safe During Write" button on the Mute lane, this lane will act as if it were in READ mode while you are writing the Volume data.
4. LATCH - does not overwrite any existing automation data UNTIL you make a change to the parameter, at which point it "latches" on to the new value until you make additional changes or stop playback. Upon stopping playback, it writes a final node and draws the envelope between that point and the next pre-existing node. If no pre-existing nodes exist, the parameter remains at this level for the rest of the session.
5. TOUCH - does not overwrite any existing automation data UNTIL you make a change to the parameter, at which point it gradually moves back to the level it was at before the change was made. For example: Track 1 Volume is set to +1dB with no automation data. In touch mode, if I drop the volume to -3dB during playback, when I take my finger off the knob (or release the mouse button) the volume level will linearly rise back to 1dB. (The time in which the return to the pre-existing parameter level occurs is modifiable. Click Edit > Preferences > MultiTrack and edit the Automatch Time setting. You can also modify the thinning parameters to reduce the number of edit point nodes captured per second.)
