AG-HVX200 FAQ
Revised 04/13/06
How is DVCPRO HD different than other HD formats?
There are several HD formats in the industry, namely D-5
HD, HDCAM, HDV and others that can be classified as
either an intermediate codec, like one that may be used
in the editing domain. DVCPRO HD’s main characteristics
are 100 Mbps, frame independent resolution (intraframe
recording), 4:2:2 color sampling, and the use of metal
particle tape or solid-state memory P2 cards.
What is the difference between DVCPRO HD and HDV?
There are several fundamental differences between the
two technologies. DVCPRO HD uses intraframe compression,
which means every frame is compressed, recorded and
edited independently. HDV uses long Groups Of Pictures
frame compression that interpolates presumed frames and
is not frame independent. This is of critical importance
during the editing process and in general requires
rendering. DVCPRO HD has 4:2:2 color sampling and HDV
has 4:2:0 color sampling making green screen and
compositing work much easier in DVCPRO HD. DVCPRO HD is
a compression scheme and can be found in tape or P2
(solid state memory) implementations. HDV is a
tape-based format, with low data rates, 25Mbps or
19MBps, only recording onto tape. DVCPRO HD is a SMPTE
standard. Different manufacturers implement HDV in
different ways. One cannot exchange content shot with
different brand names of HDV cameras. Also, HDV uses
embedded and compressed audio, where DVCPRO HD uses
uncompressed audio with 4 to 8 discrete channels. In
general, dropouts on an HDV tape can mean a significant
amount of data is lost as it will affect the entire GOP,
In DVCPRO HD tape based systems a dropout will only
affect the frame it happens on, with P2, there is no
such problem.
What are the benefits of solid-state technology?
Because solid-state recording does away with the parts
that are found on traditional tape mechanisms, it has a
quiet operation; is virtually maintenance-free and can
be used in extreme and harsh environments.
What signals does the HVX200 record?
This camera handles standard-definition in 3 modes: DV
and DVCPRO (which are 25 Mbps) and DVCPRO50, which as
the name implies, is 50 Mbps, which is also 4:2:2 and
has been compared favorably with DigiBeta. It also
handles DVCPRO HD high definition at 100 Mbps in 1080i
or 720p, recording onto P2 cards.
What’s inside a P2 card?
There are four error-free, 20MB transfer speed SD Memory
Cards, a printed circuit board, LSI computer controllers
to allow for maximum data speed, cardbus connectors and
several clamping plates and a die casting for
protection. They have been tested extensively for
durability.
What sizes of P2 cards are available?
Currently there are 2 sizes: 4GB and 8GB. Larger ones
will be forthcoming, as the consumer market drives
demand for higher capacity SD Memory Cards.
How many P2 cards can the HVX200 hold?
It can hold two P2 cards, as it has two P2 card slots.
How much recording time do I get on a P2 card?
It will depend on what mode you are recording in. For
DVCPRO it is 4 minutes per GB; in DVCPRO50, it is 2
minutes per GB; in DVCPRO HD 720p it is 1 minute per GB,
and in DVCPRO HD 1080i it is 1 minute per GB. Using the
720p Native Capture mode, only the flagged frames are
recorded so the running time will depend on the frame
rate (just like film). A rule of thumb in this mode
would be to treat 1GB as 100 feet of 16mm film or 250
feet of 35mm film. For example, running an 8GB card at
24P in this mode will give you about 20 minutes per card
of 24P HD footage. Or more simply, if shooting 720/24p,
you would get 2½ minutes per GB.
How can I record for durations longer than the P2 cards’
capacity?
In three ways: you can continuously record over from one
P2 card to the next and hot swap them for unloading, or
you can use the FS-100 mentioned above, which is an
external FireWire drive. You can also open your capture
window in your NLE and capture via FireWire to your
external drive.
Does the HVX200 record still images?
The HVX200 can do a single frame capture in the
intervalometer section of the camera. If you use an NLE
application, you will be able to select that frame on
the timeline and export it as a single still frame.
Does the HVX200 support NTSC and PAL signals?
There will be two versions of this camera: one to
support the NTSC market and one to support the PAL
market.
What frame rates does the HVX200 support?
In 720p mode this camera handles: 12, 18, 20, 22, 24,
26, 30, 32, 36, 48, 60 fps.
How does the HVX200 record 24P?
It shoots every frame as a progressive frame, so it is
true 24P (more accurately known as 23.98 fps). In most
recording modes, duplicate frames are added in a 2:3 or
a 2:3:3:2 pull-down cadence and the progressive frames
are divided into two fields in order to conform to
existing interlace 29.97 formats. The 2:3 mode follows
all of the conventions of film to tape transfer, so that
the recorded material can be treated as a film transfer
or in the 2:3:3:2 mode it can be extracted for 24 frame
editing. In the 720p "Native Capture" mode only flagged
frames are captured with 23.98 time code; these files
are directly compatible with a 720p 24-frame timeline,
and require only 40% of the storage capacity of 720p 60
fps or 1080i HD recording.
What type of lens does the HVX200 have?
It has a wide-angle Leica Dicomar high definition lens
with optical image stabilizer (which can be turned off).
It has a 13X zoom range, or rather 4.2mm to 55mm in
focal length; widest aperture is F1.6. There are a
number of other add on lenses and lens adapters that can
alter the Field of View of this lens. See Century
Precision Optics, PS Teknik, Red Rock Micro and Cinemek
for starters.
What size is the 3-CCD imager?
The 3 imagers are 1/3" CCD offering a 540 X 960 array in
a 16:9 native aspect ratio. There is a spatial offset
deployed in both the horizontal and vertical direction
making the effective resolution of the chip set to be
1440 X 810 pixels. The output of the CCD system is an
analog one and thus from here the signal is then scanned
and captured at 1080/60p. The signal is then converted
to 1080i, cross-converted to 720p or down converted to
480p/480i, or cross-converted for the many modes on this
camera. This assures the highest quality of recording.
Is the HVX200 16:9 or 4:3?
The HVX200 has 16:9 native imagers, and it is capable of
recording 4:3 video in any of the standard definition
modes.
What are the size and resolution of the LCD display?
The size is 3.5" and the resolution is 210,000 pixels.
There are two focus assist modes available; one will
zoom in on the center of the picture and give a 2X zoom
of that image, so that focusing can be checked even
during record. There is also a peaking circuit to aid in
determining proper focus.
What resolution is the viewfinder?
235,000 pixels. It has the same focusing assist
functions as the 3.5" LCD.
Does the HVX200 have manual or automatic focus?
Both manual and automatic focus are available. You can
also adjust focus manually while the auto focus is
working.
Does the HVX200 have manual or motorized zoom?
Like the DVX100, the HVX200 has both manual and
motorized zoom options. Unlike many "prosumer"
camcorders, the HVX200 has a mechanical zoom movement
rather than an optically coupled system, snap zooms are
a real possibility.
What is the zoom range of the HVX200?
13X, 4.2 to 55mm (35mm equivalent: 32.5 to 423)
What video inputs and outputs does the HVX200 have?
It pretty much covers the range of needed inputs and
outputs, as it has HD Analog Component, 1080i, 720p,
cross-converted 720p-1080i, 480i (D4) output, Composite
input/output, S-Video input/output, Standard IEEE 1394
interface and USB 2.0.
How many channels of audio does the HVX200 support?
It supports 4 channels of PCM 48K 16-Bit audio via 2 XLR
connections in DVCPRO HD, and DVCPRO50; 2 channels in
DVCPRO and DV. DV tape can also record 32K 12-Bit
signals for 2 channels live and 2 for dubbing later.
Does the HVX200 have IEEE 1394 (FireWire) interface?
Yes, both streaming and file transfer.
Does the HVX200 have USB 2.0 connectivity?
Yes, for file transfer.
What are CineGamma and NewsGamma?
In addition to regular video gamma controls, Panasonic
developed these two gamma sets specifically to help with
film-look and news production. CineGammaTM is
derived from the one found on the VariCam®,
which helps emulate the latitude of film. NewsGamma
helps to preserve important image data by suppressing
over-saturation in highlight areas during sudden changes
in contrast, which may happen as news in progress is
being captured.
What shutter speeds does the HVX200 support?
Regular shutter speed.
60i/60p mode: 1/60 (OFF), 1/100, 1/120, 1/250, 1/500,
1/1000, 1/2000 sec.
30p mode: 1/30, 1/50 (OFF), 1/60, 1/120, 1/250,
1/500,1/1000 sec.
24p/24pA mode: 1/24, 1/50 (OFF), 1/60, 1/120, 1/250,
1/500, 1/1000 sec.
Does the HVX200 support Synchro-Scan Shutter?
Progressive mode off: 1/60.3 …1/250.0
Progressive mode 30p: 1/30.1 …1/48.0 …1/250.0
Progressive mode 24p/24pA: 1/24.1 …1/48.0 …1/250.0
What are the gain settings of the HVX200?
0/+3/+6/+9/+12/+18 dB (60i/60p mode)
0/+3/+6/+9/+12/+18 dB (progressive mode (30p/24p/24pA)
(Note: set to 0dB when the slow shutter mode is used)
Can I control focus and iris remotely?
Yes. The HVX200 has a mini-plug connector that allows
for focus and iris remote controls to be plugged in.
What is the filter size of the HVX200?
82mm
What signals and frame rates does the HVX200 support on
Mini-DV tape?
While recording with the tape drive portion of the
camera, you record in 25Mbps Mini-DV mode and in 30
frames per second. 24p and 24pA are available in NTSC
models. You can also record variable frame rate footage
in 720p mode onto a P2 card and internally dub this
footage to DV, offering a unique function and effect to
your DV productions.
Can I use the HVX200 as a Mini-DV VTR source?
Using cameras as a VTR source is possible, but if this
is a function that you wish to do all of the time it is
recommended that you purchase a VTR for this purpose.
Can I record directly to a FireStore drive (Focus
Enhancements)?
Yes. The FS-100 from Focus Enhancements will give 90-100
minutes of high-definition content in 720p or 1080i
modes. In DVCPRO50 it will record 200 minutes, and in DV
or DVCPRO it will offer 400 minutes. It also supports
recording in the MXF format, so it can seamlessly be
edited by your favorite NLE applications, like Avid
Xpress HD, Final Cut Pro and Canopus Edius HD.
Can I use the FireWire output to transfer previously
recorded content from P2 cards to an external hard drive
or Apple iPod?
Yes, we have done tests on original iPod models over
FireWire by putting the camera into the "Host Mode,"
though its performance is a little slow. However, the
latest iPod models do not have a FireWire port. On a
standard 1394 drive, it would be a bit faster.
Can I transfer scene files over FireWire?
Transferring Scene Files is done using the SD Memory
Card. In fact, you can attach the Scene Files to an
email and send them to other production groups, who in
turn will be able to match their cameras to the original
one.
Can I transfer timecode over FireWire?
FireWire, as a transport specification, includes the
transfer of timecode information. So yes, timecode will
be transferred over FireWire.
What do I do with footage after I’ve recorded it on a P2
card?
There are several things you can do. You can view the
contents of a P2 card via the P2 drive connected to your
PC. Or you can import it directly to your NLE via the
camera’s FireWire port. You can transfer it to hard
drives for viewing later. There are workflow decisions
that need to be made as you initiate any project and it
is best to think it all the way through before embarking
on the project. You need to consider how you will be
handling the P2 cards and how and where you will store
the data and how are you going to put together a back
up. While not difficult, it is different than that of
tape but the reward of working in a tapeless workflow
becomes immediately apparent.
How do I archive footage shot with the HVX200?
Either in hard drives, SAIT, DLTs, LTOs, Blu-ray or DVD
solutions. There is a white paper that discusses
workflow more fully, which can be found here.
How do you attach an external SCSI DLT drive to a
Windows-based laptop?
There is an Adaptec USB to SCSI adapter. The cost is
approximately $125.
Which computers are compatible with P2?
P2 cards are compatible with computers with both Windows
and Apple operating systems. Apple computers recognize
the P2 card via the Final Cut Pro editing application
from the P2 Drive, the P2 Store or on a G4 the PCMCIA
slot or the camera. The same sources work for the PC. A
separate freeware application called P2 Viewer, supplied
with the camera, is currently only available for Windows
XP. There is a software program called HD Logger from
Imagine Products that will support the P2 Viewing on a
MAC, as well as work through many other needed archive
activities. This software is not free, but is vastly
more powerful than the freeware from Panasonic. For more
info, visit
http://www.imagineproducts.com/
Are the P2 Store and P2 Drive compatible with Windows
and Apple computers?
Yes. The P2 Store and P2 Drive support Windows 2000,
Windows XP and Apple operating systems. Drivers for all
operating systems are included with the P2 Store.
Which editing systems are compatible with the HVX200?
From Apple: Final Cut Pro; from Avid: NewsCutter® XP,
NewsCutter® Adrenaline™ FX and S/B Xpress Pro HD; from
Canopus: Edius HD. For other systems a company called
DVFilm has produced conversion software for the P2 files
called Raylight. Raylight is a real-time DVCPROHD codec
and MXF file translation program for Windows. It makes
the camera's MXF files appear as standard AVI files to
the editing system, allowing you to view or edit HVX200
footage in Sony Vegas, Adobe Premiere, After Effects,
Windows Media Player, and others. Download at
http://dvfilm.com/raylight.
What kind of battery comes standard with the HVX200?
5400mA
