SOUND AND THE MOVING IMAGE
DIFFERENT TYPES OF SOUND IN FILM
Dialogue - Person/ character talking can be recorded live in sync or synched later.
Sound Effects - used to amplify or enhance experience
Music or Score - to elicit and/or nurture emotion
Voice Over - represents narration, internal dialogue, voice of God, etc.
BASICS THINGS TO THINK OF WHEN CAPTURING SOUND
How is an audio signal captured?
Single or Dual system set up - will you be using a separate system to record sound outside of camera?
Sampling Rate (KHZ)
11 KHZ (Low Quality)
44.1 KHZ (Cd Quality)
48 KHZ (Digital Video Audio)
96 KHZ (2x 48 KHZ) - tougher on computers
192 khz (4x 48KHZ
ALWAYS RECORD UNCOMPRESSED AUDIO
RECOMMENDED DOUBLE SYSTEM SET UP:
16 or 24 bit
Preamps and audio dedicated recorders in dedicated setups are quieter than ones found in camera, so you will sometimes hear a hiss or buzz from in camera recording.
Pay attention to Mic and Line Signals
Line signal is a strong and usually from dedicated device
Mic signal is weaker signal.
If you have wrong switch - NO SOUND if a Line is switched to Mic and it will create distortion if Mic is on Line.
LEVELS: -20 t0 -12 dbfs when recording
When Editing, keep the peak between -12db and -6 db
Distance matters. Get the mic as close to the subject as possible without distortion.
BOOM MIC - with a shotgun mic usually directional, good for outdoor
Lavalier MIC - smaller wearable mics
Sets the pace, goes
Most "western"music is based around a beat. The speed of the tempo. It is measured by Beats Per Minute or BPM. We measure the BPM based on our heart rate. Average heart rate is 80-100 BPM, this is walking, easy. Slower is calm
100 - 140 BPM, it's lively or upbeat, think marching bands.
140-160 BPMs and above it's fast paced, exciting, frantic.
Most music can mix a variety of speeds or BPMs in one song. And each one can elicit different feels.
Tempo comes in common time signatures. 4/4 , 3/4 waltz like a merry-go round, 5/4
Within the tempo there are patterns. We build patterns over a beat to create a RHYTHM. It adds momentum.
MELODY - the musical sense made out of pitches ascending or descinding in frequency made up of octaves.
A short musical recurring theme that we associate with a specific character, place or idea in a film. Name means leading motif.
