Lens
The 1/4-inch CCD sensor captures images with detailed accuracy so that images will be sharp and defined. The optical zoom magnifies up to 10 times while the digital zoom, which works by electronically enhancing the optical image, reaches up to 300 times. The digital image stabilization system keeps the picture steady and solid throughout zooms and camera shakes. You can shoot visible video at night using the night shot function, which allows the camera to shoot full-spectrum video in little or no light situations. Manual controls such as focus, exposure, and white balance give the user greater flexibility in shooting.
Digital Stills
The CCD sensor has a 1.33 megapixel rating, which creates images with resolutions of up 1600 by 1200 pixels. There are three lower quality settings (1280 x 960, 1024 by 768, and 640 by 480) that you can use to save memory. The DV800 includes an 8MB MultiMedia card and is also compatible Secure Digital memory cards.
Inputs and Outputs
The DV800 comes with the standard DV IEEE1394 port which provides a lossless connection to a PC or other DV machines, as well as a USB port for image transfer. The common RCA AV connections are used for direct viewing on a television or VHS dubbing.
I haven't tried using the camcorder in especially low light situations, and I guess my expectations are lower than many other users. I don't really expect to be able to take video in the dark. Without going into details, I would say the camcorder has met my expectations for shooting without a video light, although I don't doubt that some camcorders may do better in low light.
I've seen mixed reports on the supplied battery, which is a 400 mA-hr lithium, with some claiming the battery is useless after a few charging cycles. I haven't pushed it, but I seem to be able to get at least an hour of recording out of the battery (but I also bought a 2500 mA-hr model for flexibility).
Many reviewers have severely criticized the 3.5" LCD for low resolution/sharpness. It's true that it isn't "stunning", but it's extremely useable, with sort of a matte appearance, rather than the glossy appearance of, say, a Sony. Unless you're trying to do a precise manual focus, however, I don't see the LCD as a liability, and I don't assume most users sit around watching their videos on the LCD.
Most others have also criticized the still image capability of this, and all camcorders, stating that they are far inferior to digital cameras. The DV800 has a 1.3 MP CCD, and the Sony digital camera I've been using for several years is also 1.3 MP, and I've yet to be tempted to upgrade to a higher resolution camera for our family usage, since I typically don't crop and blow up my pictures. I use both the Sony and now the JVC DV at 1280 resolution, and aside from the camcorder not having a flash (standard), I've yet to notice any difference in the pictures from the two, in good light, other than a slightly different aspect ratio. Since my Sony camera only has an LCD, and no viewfinder, I'll probably tend to use the JVC DV through its viewfinder outside in bright light, where the Sony LCD is nearly impossible to see.
As far as operation of the camcorder with a personal computer, I've found the JVC to work extraordinarily well in all modes with Windows XP, after an initial intensive debugging of the FireWire (IEEE 1394/i.Link) capability. (I have a very long thread on the Dell Community Forum documenting this process.) JVC supplies Pixela USB drivers and an application (ImageMixer) that makes good use of those drivers, within the limitations of the program. JVC, like most DV manufacturers, relies on supplied Microsoft drivers for operation over the 1394 bus.
In still camera mode (Memory mode), with a memory card installed, and when connected to a computer via USB, the JVC requires no custom drivers. It looks like a removable USB disk drive, and all images are accessible as JPEG files for copying from or to the camcorder. For retrieving video or using as a webcam over USB, the Pixela drivers must be installed, and they present a separate Video Capture and Audio Capture device. With Image Mixer, I could capture 320x240 video (Video CD) from the camcorder, either by playing back a DV tape (in Video-Play mode) or as a webcam (in Video-Auto or -Manual mode). I couldn't get the camcorder to work reliably for video over USB with the other applications I had available, so I don't know if resolution above VCD is possible over USB. DVD resolution is 720x480 @ 30 frames/second, for a data rate of almost 30 megabits per second (Mbps). USB 1.1 is limited to 12 Mbps, so unless the JVC USB implementation is 2.0, DVD-quality video transfer isn't possible over USB.
Moving on to operation over the IEEE 1394 bus (FireWire), here is where the full video capabilities of the camcorder are possible. It is possible to download still images from the memory card over 1394, but it's much more convenient to use the USB disk mode for still image operations. Contrary to another review on this site, I don't believe there is any inherent limitation in the JVC 1394 implementation that limits it to working with particular 1394 interfaces. That limitation appears to be in the Windows XP drivers, and isn't particularly specific to given camcorders, as documented in many places on the web, including my thread elsewhere. After switching to using the Microsoft 1394 bus drivers, instead of those supplied by the interface manufacturer, my JVC has worked flawlessly with my 1394 interface, which has a Texas Instrument chipset, and it also worked flawlessly with a Dell laptop with a built- in 1394 interface with TI chipset, as well as with the built-in DV interface of a Macintosh iMac.
After the initial debugging cycle, I have downloaded lots of video from my camcorder's DV tape over the 1394 interface, produced video that I burned to DVD, which played back and looked great on my 27-inch TV, and copied the edited video back to a DV tape in the camcorder (all using Ulead Video Studio 8.0, which I will be reviewing in the software section of this site shortly).
In short, the JVC GR-DV800 has done everything I've asked of it thus far, and with its flexible input and output connections, and availability of useful accessories, including lenses and filters, I consider it to be a great product.
JVC is a bit dishonest in its claims to be compatible with OHCI-compliant connections, but the camera's good and (best part) it has a MIC IN jack, which is the main reason I bought it.
I agree with the reviewers saying the low-light mode is kind of strobe-like. However, it is in True Color,/b>! If you move your hand gently (use a tripod for low light!), or focus on a scene and don't move the camera much, you will like the results. I, for one, hate the fake, green tint (infraRed-based) that Sony and some other manufacturers incorporate into their night mode. Yes, it increases overall light sensitivity by absorbing more rays from outside the usual visible spectrum, but the video looks (green!) unreal and ugly. NOT an option!
The remote has a few nice features as well, and the photograph mode is quite impressive for a digital camcorder. I took over 300 pictures at the native resolution of 1.33 MegaPixels 1280x1024 (2 Megapixel photos at 1600x1200 are produced through interpolation, don't bother with it!). I got some beautiful low-light, dawn and dusk shots, including sunsets and sea shots.
The lack of a flash forcues you to use good photography principles like keeping the subject's face well lit, but the BackLight mode is a nice semi-fix for video or pictures taken with a bright backlight (eg sun behind subject).
BE AWARE that most versions of this camera do not like LARGE SecureDigital (SD) cards. You will be able to use cards over 128 MB, but can't preview the photos or the amount of space left because the camera doesn't fully support that card size (256 and above). Stick with a 128MB card, which can hold well over 250-300 photos at the highest native resolution, and you should be satisfied!
It would have been nice to have a lens with more optical zoom, because digital zoom is an absolute joke, just like any other camcorder - the graininess introduced into the video makes it quite worthless. 10X isn't bad, though, and the clarity of video and images shot with this camera rival anything I've had a chance to compare it to (mostly similar priced and similar featured cameras from other manufacturers, owned by friends). I've made a few DVDs and amny VCDs of video captured with this camcorder, and the quality is great.
The software included isn't too bad for quick and dirty image and video capture using the USB port and included cable (half resolution video) or Firewire (you need to buy a cable, but can capture full resolution video only with Firewire). However, I strongly recommend using something nicer like at least ULead Video Studio or Sonic MyDVD or Pinnacle's Studio products, or perhaps even Adobe Premiere to make truly 'prosumer' video! Its a pity a Firewire cable isn't included, but make sure you get one.
The video (composite) output cables are excellent, and dubbing video from the DV tapes to VHS or DVD/VCD recorders couldn't get easier. I haven't played with the scene transitions on the camera, because I edit in software, but I'm sure they'll be satisfactory if you want to make VHS tapes or DVD/VCDs directly using the (cable included) RCA composite AV output.
A note on DV tapes - stick to one manufacturer, because others (like Sony) use a different technique to make their tapes and camcorder heads apparently don't like frequent switching. I have had great luck with JVC tapes (duh!) which are re-labelled Fuji tapes. I bought well over a dozen.
The camera's pass through function for analog video lets you convert it to DV which you can capture on the fly (using pass-through) on a computer to convert your old VHS tapes into flawless (as good as the original VHS at least) VCDs or DVDs. I've used this a lot as well.
The large flippable LCD screen is good for those videos when you want to be in the shot but still occasionally monitor what the camera is capturing, from a distance. It doesn't get grimy or dirty and is easy to clean anyway.
One thing to be aware of, though, is that the Nightvision feature is absolutely worthless. This camcorder is horrible and useless in low light situations. In bright light, the images are great. I have a cheaper, Sharp VLNZ105U, that beats this JVC hands down for low light shooting. So, if I am in a night shooting situation, I take the Sharp camcorder, not the JVC. I have ordered a light to mount on the JVC camcorder, which is a significant additional amount of money over what I paid for the camcorder in the first place. Maybe that will help. When you use the Nightvision it looks like special effects, everything moves in a strobe light effect, very jerky and jumpy. I don't see why they even bothered to put this "feature" on the camera.
Except for that one issue (low light shooting), so far it has been a great little camcorder.
Right out of the box it felt substantial. I thumbed through the manual while charging up the battery (can't do it off the camera) and was a little dismayed at the large amount of instructions. However, as I found out later, it's all pretty simple once you get the hang of it.
The LCD is nice and big. Others have complained that the clarity isn't great, but compared to the Sony and Cannon, I don't have a problem with it.
The controls are pretty well-oriented, although I did get a little bit of a hand cramp from using the one-finger menu dial. But that's probably just because it's new and I'm trying everything.
The 300x zoom is pretty useless above 100x. Anything that close is just too grainy. Whether that's from the lens itself or simply because things weren't intended to be viewed at 300x their normal size, I don't know. Right now, I can't imagine ever zooming that far unless I'm looking at the moon or distant landscapes.
One problem I've had is using the camera in low light using AGP or JVC's NIGHTVISION. Basically, like any camera, light collection takes time. Meaning, if you want to move the camera and you are using AGP (Automatic Gain) or the highly-vaunted NIGHTVISION, you have to move the camera very slowly to keep a focused picture. In fact, I have to use a tripod to take snapshots to prevent my pressing the button from making fuzzy pics.
I installed the included USB software on my XP system and hooked the cables up and I was able to e-mail out a picture in about 2 minutes, start to finish (including cable installation).
However, I've since tried to copy over video using the USB port and it doesn't work. I've installed the software that comes with it, but it still doesn't work. JVC website is basically no help with anything, but I've been told by some camcorder forum experts that you HAVE to (HAVE TO) use the Firewire port to txfer video instead of the USB. JVC doesn't include a FireWire cable so I've yet to try that fix out.
All in all I'm glad I bought this particular camera. It looks good, it feels good, and so far it takes good pics and video.
