- sony optical disk
- -optical disk is same size as a dvd -much larger capacity than dvd -cheapest per gb storage
- advantages of tapeless formats
- -no time spent capturing footage -metadata -ability to record proxy info -caching of material -overall increases the efficiency- more time to be creative less time spent worrying about tech issues
- panasonic p2
- -sd memory cards -put 4 sd cards on cmcia card -no mechanical parts
- firestore
- -removable hard drive -uses firewire drives -remove drive and plug into non linear editor -more of a prosumer device
- ikegami editcam
- -video stored on removable hard drive -can handle 1.5 to 6 hrs of material -remove drive and plug into non linear editor
- control track
- video heads must be synchronized with tape electronic impulses called sync pulses are recorded with each frame sychnronizes 2 tape machines for editing and also controls speed through machine
- shutter speed
- increase in shutter speed means less light comes into the camera each time shutter speed is doubled, the lends must be opened 1 f stop increasing shutter speed requires that you have enough light
- color temperature
- 3200 k indoor 5400 k outdoor
- contrast ratio
- ratio of the brightest screen area to the darkest screen area brightest divided by darkest
- f stop
- as light level dlecreases the camera needs more light measured in f stop optimum level between f/4-f/11
- foot changle
- light intensity from a candle at a distance of 1 foot
- CCD charge coupled devices
- convert light into electrical energy pixels act as photoconductors light absorption changes the electrical conductivity the more light that hits a pixel the more electrical energy released
- continuity editing
- cutting to preserve the essence of an event w/o showing all of the event
- sequences
- series of shots that logically tell a story or part of story errors: physical, time, technical, relationship, audio, event, and spatial
- long focal length
- Lends zoomed in far Less depth of field Large iris
- short focal length
- wide angle shot greater depth of field large iris
- US TV system
- 4x3 525 lines 30 frames field scans 60 fields per sec 2 fields per frame
- interlaced

- doesnt show entire head good for highly emotional
- persistence of vision
- psychological phenomenon

- physiological phenomenon
- focal length
- distance from the optical center o the lens to the front surface of the imaging device or target determines image size and angle of view
- zoom range
- ratio of how much you can change the focal length of the lengths longest divided by shortest length
- aspect ratio
- ratio of screen width to screen hight screen is wider than its height in the us 4x3 HDTV: 16x9
- underscanning
- showing entire image and leaving a border around the screen
- overscanning
- using more of the screen than you can see
