usually shorted to leave out the “- to 1,” taking for granted that it will
always be in relation to 1, an so “1.33 to 1” can just be called “1.33” In 35mm
1.33 is known as the Academy Aperture. In 35mm the image is usually shot with

BetaCam & BetaCam SP
BetaCam was first introduced in 1982. It is currently geared
for broadcast use, although there have been some less expensive models destined
more for industrial use. Pictures you will get using a BetaCam system (or other
component format) will generally be markedly superior to those you would get
using any of the preceding formats. Colors in particular come out looking much
more vibrant and objects appear three-dimensional. The superiority of BetaCam
shots comes partly from the technical aspects of the tape format but also in
large part because of the use of superior optics and other camcorder and VTR
components (and generally better operators!).
The difference between BetaCam and BetaCam SP, introduced in
1986, is in the tape. Betacam SP uses a metal tape and is an improvement over
BetaCam.
BetaCam cassettes are large. Ninety minute cassettes
measures 5.5 by 10 inches (14 by 25 cm). Typically BetaCam field units
(camcorders or dockable decks) handle only smaller cassettes with shorter lengths
of tape (30 minutes and less). These smaller cassettes are 4 by 6 inches (10 by
16 cm) in size.
Betamax
Betamax tapes were a format originally introduced by Sony in
the 80's. It was thought to be a better format at the time. However, the Beta
vs VHS wars took place and VHS was the victor. There are still a few Beta fans
out there though and you can still get a Betamax machine if you look around.

Digital8. A regular 8MM or HI-8 tape will record up to 60 minutes of digital
video and audio. Because of the design, using regular tapes is not a problem,
but it uses twice as much tape. A 2 hour HI-8 or 8MM tape will record 60
minutes when done in the Digital mode. For more information on Digital8, Click

record individual tracks, but can only be performed onto a previously recorded
tape (blacked or coded tape) as then all the timing control signals are already
on tape. An assemble edit is a method for building a videotape in which a
series of clips are placed one after the other to create, or assemble, a

Introduced in 1986, MII is Panasonic's answer to Betacam SP.
All MII tape is metal. The 90 minute cassette at 4 by 8 inches (11 by 19 cm) is
considerably smaller than the 90 minute Betacam SP cassette. However the
dockable decks take only a small 20 minute cassette (3.6 by 5 inches - 9 by 13
cm). Technically, MII is equal to or superior to Betacam SP. Panasonic MII
field equipment includes several small dockable decks usable with a variety of
camera heads and some excellent portable decks.
Be aware if you get into MII that at some point repairs may
become an issue and that few duplicating facilities or clients are likely to
have MII. Therefore you will probably have to copy your MII programs to another
format at some stage.
Mini DV
Mini DV tapes are the smallest of the video formats. They
take and maintain crystal clear images because of the nature of a digital
format. Editing enthusiasts benefit from Mini DV as well, since copying between
two units is done with no quality loss. That means edited or copied video looks
and sounds every bit as good as the original footage. Mini DV tapes are
available in 30, 60 and 63 minute lengths. You can also have Mini DV tapes
transferred to VHS. For more information on Mini DV, Click Here.

VHS & VHS/C
Abbreviation for video home system, a VCR format pioneered
by JVC. VHS/C and full size VHS record at a slightly lower resolution than 8MM.
Their appeal, or course, is the convenience of easy playback. The large VHS
camcorders are almost a thing of the past at this point. There are still a few
models available, but their substantial size and weight make them a difficult sell
against smaller camcorders. VHS/C compact models, on the other hand, remain a
popular choice, offering many of the same key features as 8MM camcorders, at an
equally affordable price.

Webcasting
Also known as streaming, the process of broadcasting a live
video feed on the internet as in our live video streaming services.
Webmercial
Any commercial or promotional video intended specifically
for distribution on the web.
Wet Gate - A contact printing method, made on a specially
equipped printing machine, where the film is in a liquid that temporarily fills
in any scratches on the base, preventing them from refracting light and showing
up in the print. Commonly, answer prints are printed with a wet gate. Labs
often charge a little extra for wet gate printing.
Whip Pan (swish pan) - Extremely rapid camera movement from
left to right or right to left, appearing as an image blur. Two such pans in
the same direction, edited together one moving from, the other moving to a
stationary shot can effectively convey the passage of time or a change of
location.
Wide Lens - A lens with a focal length smaller than 25mm in
16mm, or 50mm in 35mm, which, like looking into the wrong end of a pair of binoculars,
provides an extended view of a large area.
Wild - Not sync. A wild motor is one that runs close to 24
frames per second, but not close enough for sync sound. Also applies in a few
other cases, such as, if you are filming a rear screen projection scene and the
projector and camera are not Interlocked they can be said to be running wild.
Wild Sound - Non-sync sound, recorded without the camera
running, usually recorded to supplement the sync takes.
White Balance - Adjusting a camera's light filtering system
to ensure that the camera accurately records true colors. Different lighting
conditions affect how cameras record colors.
Wipe - A type of transition that uses a moving edge to
replace the current clip to reveal the next clip.
Workprint - A positive copy of the original negative that is
cut during the editing process. At the end of editing the original negative is
then cut by the negative cutter to match the workprint shot for shot, and an
answer print struck from the cut negative. A workprint can also be made from
reversal original.
Wrap or “It’s a Wrap!” - What to say when you are done
shooting, either for the day, at that particular set, or on the entire film.
Usually if it’s not the final shoot you would say you are just going to “wrap
for the day.”

White Balance
Assures the correct balance of red, green, and blue. Because
these
colors are used to create all other colors in television,
white balancing a
camera enables you to bring the colors in line for the
existing lighting
conditions. Also refers to a camera control that accurately
sets light levels
on a white surface.
Wide Angle
The wide-angle position of a lens enables the lens to
capture a wider area
of view. Be careful when video taping people with a
wide-angle lens at close
range.
X
Xenon:
A high intensity light, with a polished parabolic reflector.
(Lighting)
XLR:
One of several varieties of sound connectors having three or
more conductors plus an outer shell which shields the connectors and locks the
connectors into place. (Sound)
X-Y Pattern:
A pair of cardioid microphones or elements aimed in crossed
directions which feed two channels for stereo pickup. (Sound)
Y
Y M C Numbers:
The 'timing lights' that the negative is printed at,
representing the numerical value of the red, blue and green lights used in the
printing process. These printing lights are referred to by their complements:
yellow, magenta, and cyan.
Y lead - A lead or cable, usually audio which splits a
single feed into two feeds, this is a passive connection.
Y/C Video
Z
Zero Cut:
A method of preparing A and B rolls for printing in which
the original shots overlap several frames or more. The change from one roll to
another to match the edited workprint is done automatically by the printer.
(Film Editing)
Zoom:
An optical effect in which the image rapidly grows larger or
smaller as though the camera is moving closer or away from its subject.
zoom On a camera, to change the focal length to/from
wide-angle and telephoto. In post-production, an editing filter that simulates
the effect of having a camera move in very close to the subject, objects, or
areas in a frame; or move away from the subject and display a wide view of the
entire frame.
Z axis - The plane or axis in which an object moves closer
or further away from the viewer
Zoom - On a camera, to change the focal length to/from
wide-angle and telephoto. In post-production, an editing filter that simulates
