From Panasonic Web site, here are
some of the FAQ regarding the HVX200
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 2˝
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 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.
