montage definitions
Montage Definitions
  • Soviet montage theory is an approach to understanding and creating cinema that relies heavily upon editing
  • In classical Hollywood cinema, a "montage sequence" is a short segment in a film in which narrative information is presented in a condensed fashion.

  • Blue Velvet
  • Psycho
  • Raging Bull
  • Citizen Kane
montage technique
Montage Technique
  • Camera needs to move anywhere from 25 to 45 degrees in order to make a smooth transition
  • When moving through different symbolic shots—it is important to change up the angles and image sizing
  • Think about visual impact
sound recording
Sound Recording
  • Video is on the screen, but sound is everywhere!
  • People can become engrossed in scenes with shaky camera or possibly bad lighting, but if the sound is bad you lose your audience
  • Also, if sound peaks—over-modulates it is unusable
what is sound
What is sound?
  • Sound is energy that travels through a medium like air as a wave
  • When something makes a sound, it causes molecules of the air to vibrate, i.e. to alternately bunch together (compress) and to move apart (rarefy)
ears and brain
Ears and Brain
  • When sound waves hit your ear, they cause your ear drum to vibrate, which in turn sends nerve impulses to your brain.
  • This allows you to perceive the vibrations as sound
microphone
Microphone
  • When sound waves hit a microphone, they cause a diaphragm inside the mic to vibrate which generates an electrical current known as the audio signal. This can be sent to an audio recorder
dynamic mics
Dynamic Mics
  • Dynamic mics don’t need a battery
  • Rugged
  • Cheap
  • Handle loud sounds
  • Not sensitive to soft sounds
condenser mics
Condenser Mics
  • More sensitive than dynamic mics
  • They have a greater frequency response
  • They need a battery
  • They can’t handle very loud sounds
dynamic
Dynamic

Dynamic microphones use a simple magnet and coil of wire to convert sound waves into

a signal. Here’s how it works: a thin diaphragm with a coil of fine wire attached vibrates when

struck by sound waves. This causes the coil of wire to move back and forth around a magnet,

creating a small amount of electricity, which flows out of the microphone’s connector and

through the microphone cable.

condenser
Condenser

Condenser microphones (sometimes called electret condenser microphones) use an

even thinner diaphgragm than the dynamic type stretched tight just above a piece of flat

metal or metal-coated ceramic, called a backplate. When a fixed electrical charge is placed on the diaphragm/backplate assembly, its electrical output varies depending on the

movements of the diaphragm, which vibrates in response to sound waves. This output signal

is extremely weak and subject to outside electrical interference, however, so it must be

modified and/or amplified by a circuit called a preamplifier

balanced audio cable
Balanced Audio Cable

XLR (X-linked lymphocyte regulated)

cables have 3 pins, a circular connector and are used to deliver balanced microphone and line-level signals over long distances. An XLR cable\'s ability to deliver a balanced signal means that the final audio signal will have less unwanted noise from outside electrical interferences. This preserves the original audio signal, even over long distances and near other electronic devices.

directional
Directional
  • Omni-directional
  • Cardioid
  • Shotgun (uni-directional)
omnidirectional
Omnidirectional

– An omnidirectional microphone picks up sound equally from all

directions (the prefix “omni” means “all”). An omnimic will pick up sound from above, below,

in front of, behind, and to the side of the mic in a 360 degree sphere. The polar pattern for an

omni, accordingly, is roughly circular.

cardiod unidirectional
Cardiod: Unidirectional

By far the most common type of unidirectional microphone is the cardioid, so named

because its polar pattern resembles a heart-shaped figure.

shotgun
Shotgun
  • Doesn’t zoom in on sounds
  • It narrows the field of sounds it’s sensitive to
  • Cuts out undesirable sounds
shotgun1
Shotgun –

The shotgun microphone is so named because

the long, slotted tube in front of the microphone cartridge makes

it resemble a shotgun. This “interference tube” makes shotgun

mics significantly less sensitive to sound coming from the side

and rear than other directional microphones. A shotgun mic’s

extremely directional pickup pattern (called a line/gradient

pattern) makes these popular for news gathering, outdoor sports

coverage and TV/film production.

Tips

Shotgun mics can be

positioned slightly above, below, or to the side of the

sound source, so that the mic does not appear in the

camera frame. Try to avoid aiming the mic at a hard

surface, such as a tile floor, brick wall, or hard ceiling.

These surfaces reflect sound waves, and may reflect

background noise into the microphone or cause the

sound to be slightly hollow. A heavy blanket can be

placed on a reflective surface to provide some

temporary sound absorption. Shotgun mics are more

sensitive to wind noise than standard microphones,

so try to avoid moving the mic rapidly and use a foam windscreen if possible. Larger

“zeppelin” or “blimp” type windscreens are usually necessary outdoors. Also, it’s a

good idea to use a rubber-isolated shock mount to control handling noise that may

be transmitted through a stand or boom.

tips and tricks
Tips and Tricks
  • Position the mic as close to the source as possible
  • Especially important when recording dialogue
  • The difference between great footage and unusable footage is whether or not the dialogue is well recorded or not
  • Controlled situations are easier to work with
headphones
Headphones
  • Always where headphones—preferably ones that cover your ears
problems with camera mics
Problems with Camera Mics
  • They can’t detach
  • They tend to be omni-directional
  • They pic up sound from the camera
external mic
External Mic
  • Using an external mic
  • The camera can be placed for visuals while the microphone can be placed for best possible audio
  • Audio cable noise
  • Keep mic and sound person out of the shot

  • It can be clipped to your subject’s shirt
