Video Production: Light and Sound

  1. 1. Digital Media Production Com 3340 Amani Channel, MA
  2. 2. Class Schedule No Quiz! Assignment 1 Review/Critique Class Review Talk About Cameras Chapter 4/5/6 Light and Sound In Class Assignment - Interviews
  3. 3. Photo Assignment Do the photos tell a story? Are they visually interesting? Composition, Lighting, In focus? Write up? 5Ws and H Accurate, Spelling , Typos? Interview
  4. 4. Intro to Video Production Visual storytelling is the art and science of using visual images, sound, and graphics/text to create an emotional connection with the viewers. Visuals can be photos or video. Sound can be interviews (actualities) or music. Why do you like to watch films/video?
  5. 5. Why Light Light is the basis of visual media Quantity, Quality, Direction, Color and Sources The amount of light (Exposure) Lumen: Quality of light perceived by the human eye Illuminance: The brightness (foot candles/lux) Contrast: Comparison of the brightest and darkest area in the frame. Waveform Monitor: Displays the brightness range
  6. 6. Quality How the light creates the look and mood Direct light (hard/spotted) Sun, spotlight – hard shadows/dramatic Soft light (diffused/flooded) less intense, even or soft shadows
  7. 7. How to Light Three point lighting Key light Fill light Back light
  8. 8. Color Temperature All light isn’t equal Measured in Kelvin Incandescant bulb = 3200K Direct sunlight = 5000k You should always white balance
  9. 9. Sound With video, good sound is just as if not more important than video Microphone: Equipment that turns sound into an electromagnetic signal Sound waves: Vibrations that travel through air Crest: maximum air pressure - trough: release Frequency: Number of cycles that the sound wave travels in one second Pitch: high/low Amplitude: Height of the wave Decibel: How amplitude is measured
  10. 10. Microphones Need to know what kind of speech, instrument, or situation that you’re capturing Transducer: Transduction - converting sound Two main kinds of mics: Dynamic/Condenser Dynamic: Durable, no battery Condenser: More sensitive/phantom power/battery Ribbon: (sometimes called dynamic)
  11. 11. Pickup Pattern Mics hear sound differently pp. 130/149 Omnidirectional, bidirectional, unidirectional (cardiod) Omni – Picks up sound from every direction Bi – Picks up sound from two opposite directions Uni – Heart shaped-narrow range of sound
  12. 12. Type of Mics Handheld: Good for run and gun, need to move the mic – a bit obtrusive. Condenser/or dynamic Lavaliere: (Personal) Clip/lapel – condenser – good for sit down interviews – hands free Shotgun: Long mics (look like a gun) – captures sound from a distance (1-15 feet). Usually condenser
  13. 13. Quality of Sound VU/LED meters: Measures sound wave voltage Peak 0dB = 100% (above that audio will distort) Overmodulation: distortion Recording clean sound Monitor with headphones Test record Patience
