The AG-DVX100 has captured the imagination of creative filmmakers, broadcasters, and
video professionals around the world, with its 24p (progressive) capabilities.
Panasonic has won a total of 15 Emmys, 12 of them for advancements in the area of digital
video technology. Panasonic’s engineers are continuously pushing the limits of product design and the AG-DVX100 is a prime example of their innovation and imagination.
What is 24p?
Lets start with film, which is shot at 24 frames per second. Inherent in this capture rate, is a
motion blur that is used by the artistic filmmaker to draw the attention of the viewer to his
subject. In the movie theater, film is projected at 48 frames per second due to a shutter in
the projector. The AG-DVX100 uses an electronic shutter which the user can set to different speeds.
“When you watch 24p, you know you are being told a story”. It’s a different look. It’s the
difference between the look of a soap opera or the six o’clock news and the look of a feature film.
There is a three part answer to what must be done to create the cinematic look in video
What is Cine Gamma?
Fact: The contrast ratio of film is greater than contrast ratio of video. Can the range of
bright to dark areas be correctly exposed in a scene? Video has been optimized for high
ambient lighting during image capture (studio) and viewing (living room). Therefore image
brightness has a been much more important than contrast ratio. Film, when used in cinematic presentations, has a very high wide dynamic range providing great detail in both the
brightest and darkest areas of the image. The Cine-like Gamma feature of the AG-DVX100
emulates this wider exposure range characteristic and with the recommended 1/2 f-stop
under exposure should help to maintain increased highlight handling abilities.
What is Progressive?
Rather than capturing one half of a picture (the odd lines) and 1/60th of a second later capturing the second half of the picture (the even lines), wouldn't it be better to capture an entire frame of video with no temporal (time) difference? Progressive recording does accomplishes this! What progressive recording does is creates a picture with double the scan
lines of a conventional interlaced picture, to create a noticeably sharper image.
What is 24p Playback?
If you made a recording in 24p or 24p advanced and now you want to play it back
on a standard NTSC video monitor. The AG-DVX100
version circuit so that you can playback your 24p recordings on a NTSC Monitor. There are
two different schemes used in the AG-DVX100,
use a 2:3 pulldown scheme and in 24p Advanced mode we use 2:3:3:2. This is actually a
method of mapping the 24p into the 30 frames per second NTSC standard video. See the
next page for additional details.

Main Features
New CCD Imaging System
Exceptional picture quality, due to a new 1/3 inch, three CCD progressive imaging system
that has 410,000 pixels per chip. This new system was developed specifically for broadcast
and professional applications. These new CCD’s are able to record light as low as three
lux, enabling the shooter to record nighttime events in good detail. The picture quality is
outstanding, with a high signal- to- noise ratio and low smear in bright areas.
Newly developed Zoom Lens
The DVX100 uses a Leica Dicomar ™ lens which incorporates the optical technology of
Leica Camera AG. This lens system employs 15 lens elements in 11 groups, including two
aspherical lenses, to render a shaper image. A Leica multicoating process is applied to the
lenses to reduce flare and ghosts. The 10X zoom has been designed to increase the lens’
wide-angle (f=4.5 to 45mm) capabilities. The zoom lens utilizes a cam-driven manual zoom
ring, with quick, nimble manual zooming as well as a multi-speed servo driven zoom rocker
switch, plus a three-speed handle zoom.
Optical Image Stabilizer Compensates for Hand Held Production
Incorporated in the DVX100 is an OIS (Optical Image Stabilizer) that compensates for slight
hand shaking that may occur when shooting handheld.
A gyrosensor detects handshake and sends signals to a linear motor, which adjusts the lens
to compensate. This process takes place prior to the CCD image capture rather than in the
downstream electronic processing, this minimizes any effect of handshake.
World’s First DV 24p Mode and Cine-Like Gamma
The DVX100 is the world’s first handheld camera designed with video & cinema looks. You
have a choice of three shooting modes, which are selectable, 24p (24 fps progressive) for
images with a movie-like look and motion, 30p (30 fps progressive) or standard 60i (60 fps
interlaced). Images that are captured in 24p mode, Re converted to either 2:3 (24p Mode)
or (24p Advanced) with a 2:3:3:2 pulldown sequence. And recorded onto the video tape in
the standard 60i Video format, which allows for playback on an ordinary DV VCR and TV
monitor and edited on a DV system.

HIGH Bright images with enhanced gradation in dark areas and soft contrast.
Scene File Dial for Quick, Easy Camera Setup
The scene file dial which is located on the back of the camcorder sets up a variety of
shooting conditions, and later you can instantly retrieve the settings for future use. Six
suggested preset files are provided (F1 to F6) by the factory . You can freely change
any of the six file names and their settings.

The DVX100 records SMPTE- compliant VITC onto the Sub-code area of the videotape.
Select from DF / NDF and Free Run/Rec Run modes, and use a preset or regen. User bits
(UB) are also provided, letting you record your choice of date, time, TC value, frame rate or
user data. In 24p the time code is in NDF mode only.
IEEE 1394 terminal for non-linear production with Synchro Lock Function
Equipped with an IEEE 1394-compliant 4-pin DV terminal that makes it easy to upload data
to a PC and dub onto a DV recorder. This terminal also features a new synchro lock function that allows the AG-DVX100 to remotely start and stop an external DV device connected
to it via a DV cable, such as the AG-DV1DC portable mini-DV recorder.
XLR Audio Input with +48 Volts Phantom Power Supply
In addition to a built-in stereo microphone, the DVX100 is equipped with two XLR audio input connectors with switchable +48 volts phantom power. Both input 1 and Input 2 can be
switched between line and mic with hard switches at the front of the camcorder. Auto gain
level can be turned on and off, and the input mic level (-50dB / -60 dB) can be selected from
the menu to ensure proper matching to an external MIC output or the environment.
The DVX100 has more special features that will make the Broadcaster or professional
shooter’s job much easier.
In order to properly control this camera for generating the most powerful video images,
more operators should understand camera process terminology.
Experienced camera operators know there are always tradeoffs in every shooting situation.
You’ll trade shutter speeds for depth of focus, resolution for sensitivity, detail for noise, and
the list goes on. The DVX100’s extensive menu system will provide the camera operator
with additional tools for more creative solutions for image capture.
The following menu descriptions show diagrams of these menus and explain the effects of
each setup function.

How to use the Setup and operator Menus
The DVX100 offers the operator an extremely flexible setup capability.
There are basically two groups of menus, one for Camera functions and the other for VCR
Functions. These two groups give you the opportunity to choose from 73 items. Some of
the menu items are used jointly in the camera and the VCR.
In order to access the menus, first make sure you are not in the record mode. Choose the
camera or VCR mode, by pressing the Camera/VCR button located on the lower back section of the camcorder. Now press the menu button located near the viewfinder marked
MENU.
Once you pressed the MENU button, the menu will appear in the EVF and also on the LCD
screen depending on where the DISPLAY menu is set. (EVF ON / OFF)

Celsius carbon black emits a light. The color temperature of that light is said to be 3200
Kelvin (3000 Celsius equals 3200 Kelvin). Color temperature generally expresses chromaticity of a source of light such as indoor or outdoor light. For example, if the temperature is
relatively low, the light appears reddish. As the temperature increase, the light changed
from red to orange to yellow to white. So when a camera is used with light whose color
temperature is other than 3200K, use the appropriate color temperature conversion filter or
setting. The color Temp setting allow you to finely adjust the color temperature, after the
white balance has been adjusted.

Aspect Conversion
The standard images have an aspect ratio of 4:3. When placed in 16:9 aspect ratio the images are recorded with black bands across the top and bottom of the screen creating the
16 by 9 or letter box image. This method is called letterbox and has the major advantage of
WYSIWYG (What You See Is What You Get). It you use an external anamorphic lens
adaptor, about 25% higher vertical resolution can be obtained which may be more important
for film out applications. If Letterbox is selected, the normal CCD based imager signal output of 720 pixels H by 480 pixels V is cropped down to 720 pixels H by 360 pixels V. The
remaining 60 pixels at the top and bottom of the picture are forced to black. When an external anmorphic lens is used the source image is optically converted from widescreen 16:9
aspect down to a 12:9 aspect (4:3). Therefore the entire surface of the CCD based imager
can be used to capture the image, yielding a full 480 lines of vertical resolution.

Time Code
special internal generator will place an 80 bit code or number on every recorded frame. The
VCR will use this number for precise identification of a frame when editing. This code is recorded with the video and audio signals and is stored in the sub code area on the DV tape.
This code contains the hour, minute, second and frame number.
In the 80 bits of time code you have a lot of information, such as drop frame information,
color frame information and user bit information.
The drop frame is used to keep accurate timing between the vertical timing and the actual
time. The drop frame is bit number 10, this bit identifies if the drop frame or the non-drop
frame format is being used. If it is “1” the unit is placed into the drop frame mode and will
account for the missing frame numbers which are missing due to the timing of the vertical
and time. If it is “0” it will be placed into the Non-drop Mode. In the 24p mode we use NDF
only.
There are 32 User Bits in each 80 bit code, these user bits can be used to identify the user
information, the time, the date, the time code generators value, or the frame rate..
There are two ways to start recording time code, record run and free run. Normally, for
most productions the VCR’s time code is set to the Record run mode. In this mode the
time code will be set to zero at the start of the day’s recording (operates only during record)
and a continuous record is produced on each video tape covering all takes. In the free run
mode the time code is running regardless of the VCR’s operation mode.

4:1:1 A sampling frequency ratio used in digitizing a video picture’s luminance and color
difference components (Y, R-Y, and B-Y). In this ratio the luminance is sampled at 13.5
MHz and R-Y , B-Y are each sampled at 3.37 MHz.
4:2:2 A sampling frequency ratio used in digitizing a video picture’s luminance and color
difference components (Y, R-Y, and B-Y). In this ratio the luminance is sampled at 13.5
MHz and R-Y, B-Y are each sampled at 6.75 MHz. This method of digitizing provides a
wider chrominance bandwidth relative to luminance.
A
Automatic Level Control, a circuit that is used to maintain a constant signal level.
ALC
Amplifier A component that increases the level of an audio signal from line level to speaker
level.
Analog A signal that can be continuously varied in amplitude and frequency.
Analog Components Video signals in which a continuously variable voltage or current
represents the value of a pixel.
Aspect Ratio
on a screen. The old standard NTSC aspect ratio was 1.33 to 1 or 4 to 3, but now with at
advent High Definition technology 16 by 9 is common.
B
Back Light The main function of the backlight is to separate the individual subjects from the
background and give them depth and dimension.
Back Porch The period of time during horizontal blanking that follows the horizontal sync
pulse and continues to the beginning of active video.
Backlit Refers to the illumination used to light a projectors control panel or the buttons of a
remote control, so it can be used in the dark.
Black Level
black areas of the picture.
Blanking or Composite Blanking
tal and vertical components and is at its negative level whenever video is to be blanked or
turned off.
Blanking Level Also known as pedestal, it is the level of a video signal, which separates
the range that contains the picture information from the range that contains the synchronizing information. The level of the front and back porches. Is Zero IEEE units.
C
Charge Coupled Device
CCD
CCIR -
which now falls under the control of the ITU-R.
CCIR 601 (ITU-R 601) - This standard defines the encoding parameters of digital television.
Charged Coupled Device Is a sensor used in scanners, camcorders, digital cameras, etc.,
to capture an image. CCDs work by converting light into electrical energy.
Chroma The color information contained in a video signal, consisting of hue (phase angle)
and saturation (amplitude) of the color sub carrier. Also, known as Chrominance.
Chrominance
brightness or luminance of the signal, e.g. black, gray and white, have no chrominance, but
any colored signal has both chrominance and luminance. U,V: Cr, Cb: I,Q: (R-Y, B-Y) represent the chrominance information of a signal.

Color Bars
Coder Decoder, a device used to encode a signal and decode it.
A test signal that should be recorded at the beginning of every videotape. The
color bars test signal provides the necessary elements of a video signal that are added during the initial set up of a tape machine.
Color Burst A few (8 to 10) cycles of 3.58MHz color sub carrier, which occur during the
back porch interval. Color burst amplitude is 40 IEEE units and phase is 180 degrees. The
color oscillator of a color television receiver is phase locked to the color burst.
Color Difference Signal The calculation of the chroma signal (R-Y, B-Y and G).
Color Phase
The correct timing relationship within a color display - color is considered to
be in-phase when the hue is reproduced correctly.
Color Sub carrier
The 3.58MHz signal which carries color information. This signal is superimposed on the luminance level. Amplitude of the color sub carrier represents saturation
and phase angle represents hue.
Color Temperature A measurement of overall color of a source of light, measured in degrees Kelvin (K). The higher the Kelvin reading the more blue the light, the lower the Kelvin
Temperature the redder the light. Normally, video uses lights that are 3200 Degrees Kelvin.
Component The normal interpretation of a component video signal is one in which the luminance and chrominance are sent as separate components, e.g. Analog components in MII
and Betacam VCRs, digital components UCRCB in CCIR re 601. RGB is, however, also a
component signal. Component video signals retain maximum bandwidth, unlike composite
systems.
Composite A composite video signal is one in which the luminance and chrominance information have been combined using one of the coding standards: NTSC, PAL, SECAM, etc.
Composite Sync A signal consisting of horizontal sync pulses, vertical sync pulses, and
equalizing pulses only, with a no signal reference level.
Composite Video A mixed signal comprised of the luminance (black and white), chrominance (color), blanking pulses, sync pulses and color burst.
Compression
A process used to store digital information in a smaller block of space than it
would normally take
Compression Ratio
This is the ratio of data in the original video picture signal to the
amount of data after compression.
Contrast The range of light and dark values in a picture or the ratio between the maximum
and the minimum brightness values. Low contrast is shown mainly as shades of gray, while
high contrast is shown as blacks and whites with very little gray. It is also a TV monitor adjustment, which increases or decreases the level of contrast of a televised picture.
Contrast Ratio
A method of measuring the dynamic range of an image. A large contrast
ratio indicates that the projector works well despite extraneous light.

Digital information stored or used by a computer
dB Decibel
dBm A measurement of sound, measurement made across 600 ohms.
DCT - Discrete Cosine Transformer is widely used to compress video; here 8x8 picture ele-
ments are converted to 8x8 frequency elements. This way the higher frequency numbers
can be minimized and compression made simpler.

Flying Erase Head A special video erase head that allow for cleaner edits.
F Number In lenses with adjustable irises, the maximum iris opening is expressed as a ra-
tio, (focal length of the lens) (maximum diameter of aperture).
Focal Length
The distance from the center of the lens to a plane at which point a sharp image of an object viewed at an infinite distance from the camera is produced. The focal
length determines the size of the image and the angle of the field of view seen by the camera through the lens. That is the distance from the center of lens to the pickup device.

other colors within the limits of a system. All non-primary colors are mixtures of two or
more of the primary colors. In television, the primary colors are specific sets of red, green,
and blue.
Progressive scan
Computer images are all progressively scanned. Now, we are using
this type of scanning for HDTV. Instead of having two fields and interlacing them together
to form a frame or an image, we show each frame of a video image completely, from top
to bottom, not interlaced.

times video signals.
Resolution
(A) A measure of the ability of a camera or television system to reproduce detail. That is the number of picture elements that can be reproduced with good definition. It
is a factor of the pickup device or the TV CRT characteristics and the signal bandwidth.
(B) Generally called horizontal
resolution. It can be evaluated by establishing the limit to which lines can be distinguished
on a test pattern. A larger resolution value means a broader frequency band of the video
signal. (C) A measure of the greatest amount of detail that can be seen, or resolved, in an
image. Often incorrectly expresses as a number of pixels on a given line. More correct is
the bandwidth.

signal.
Signal-to-Noise Ratio (S/N) - An S/N ratio can be given for the luminance signal, chrominance signal; and audio signal. The S/N ratio is the ratio of noise to actual total signal, and
it shows how much higher the signal level is than the level of noise. It is expressed in decibels (dB), and the bigger the value is, the more crisp and clear the picture and sound will
be during playback.

a continuous sine wave, usually generated and distributed at 2 volts in amplitude, and has
a frequency of 3.579545MHz. Sub carrier is usually divided down from a primary crystal
running at 4.318180MHz, and that divided by 4 is 3.579545. All other synchronizing signals are directly divided down from
sub carrier.
Sync Also Composite Sync - This signal is derived from a composite or combination of
horizontal and vertical drives, with some slightly narrowed and delayed pulses as well as
the addition of equalizing pulses. It is one of the more popular signals used in video
41

be an audio signal recorded on Track 2 or a video signal that is recorded in the vertical
interval of a tape.
Time Code Editing
By recording a sequential time code along with the video and audio
material, you can obtain a more precise reference for editing. Each frame has its own
number or code, which tells the time in hours, minutes, and seconds, and includes a frame
number. The world standard code is called SMPTE (Society of Motion Picture and Television Engineers) and has also been adopted by the IEC (International Elecrotechnical Commission). Time codes permit very fast and accurate editing. Automatic editing is possible
under computer control.
