1.2. Buying a DV Camcorder

If you already own a DV camcorder, you can safely skip to the next chapterunless you've always wondered what this or that button on your camcorder does. In that case, surveying the following pages may enlighten you.

1.2.1. DV Camcorder Features: Which Are Worthwhile?

Like any hot new technology, DV camcorders started out expensive($2, 500 in 1996) and continue to plummet in price. At this writing, basic models start at $350; prosumer models hover around $2,000; many TV crews are adopting $3,500 models like the Canon XL1 or Sony's high-definition FX1; and the fanciest, professional, commercial- filmmaking models go for $10, 000. All of these camcorders are teeming with features and require a thick brochure to list them all.

So how do you know which to buy? Here's a rundown of the most frequently advertised DV camcorder features, along with a frank assessment of their value to the quality-obsessed iMovie fan.

1.2.1.1 FireWire connector

FireWire is Apple's term for the tiny, compact connector on the side of most DV camcorders. When you attach a FireWire cable, this jack connects the camera to your FireWire-equipped Mac. Other companies have different names for this connectoryou may see it called IEEE-1394, i.Link, DV In/Out, or DV Terminal.

If the camera you're considering doesn't have this feature, don't buy it; you can't use that camera with iMovie (or any other DV software).

1.2.1.2 Analog inputs

This single feature may be important enough to determine your camcorder choice by itself. Analog inputs are connectors on the camcorder (see Figure 1-3) into which you can connect older, pre-DV equipment, such as your VCR, your old 8mm camcorder, and so on. There's no easier, less expensive method of transferring older footage into your DV camcorderor directly into iMovie.

This technique is described in more detail in Chapter 4. For now, note only that the alternative method of transferring pre-DV footage into DV format is to buy a $200 converter boxan unnecessary purchase if your DV camcorder has analog inputs.

Figure 1-3. Most camcorders offer inputs known as RCA connectors. Better models offer an S-video connector too, for much higher quality. (Most compact models require a special cable with RCA connectors on one end and a miniplug on the camcorder end, like the one shown here. Don't lose this cable! You also need it to play your camcorder footage on TV.)

1.2.1.3 Three chips (three-CCDs)

Professional camcorders offer three individual image sensors, one for each color component of a video picture: red, green, and blue. These camcorders are advertised as having three chips or CCDs ( charge- coupled devices electronic plates, covered with thousands of individual light sensors, that convert light rays into a digital signal). The result is even more spectacular picture quality, resolution, and color rendition than the less-expensive, one-CCD cameras .

Unfortunately , you'll pay extra for this breathtaking video quality. Most three-chip camcorders are larger and more expensive than one-chip cams (see the photos in Figure 1-8)but they deliver much better color.

Not all three-chip models are big and pricey. Panasonic sells one for $600 that's no larger than a standard Mini DV camcorder. Note, however, that it contains three very small CCDs, so the quality improvement is visible primarily in bright, outdoor scenes.

1.2.1.4 LCD viewfinder

In the olden days, you'd set up your shots and monitor your filming by looking through a tiny glass eyepiece, exactly like those on today's 35mm still cameras. Today, virtually all camcorders offer an alternative to the eyepiece: a small TV screen known as an LCD.(LCD stands for liquid crystal display, the technology used to produce the image. As you may have noticed, it's the same technology used in laptop screens.) In most cases, this LCD panel swings out from the side of the camera (see Figure 1-4).

Figure 1-4. Your camcorder's LCD screen can rotate 180 degrees to face front; that's useful when you want to film yourself. Without an LCD screen, you'd have no idea whether or not you were centered in the frame. You can usually flip the LCD so far around, in fact, that you can press it flat against the camcorder, screen side out. That's a nice way to play back your footage for a couple of onlookers.

The LCD means that when you're shooting, you can see what the camcorder sees without having to mash your face against the eyepiece. Better yet, after shooting, you can play back your footage. And thanks to the small, built-in speaker found on every sub-$1, 500 camcorder, you can watch your work played back on the LCD screen while still "on location. "

It's worth noting, by the way, that what you see isn't exactly what you get. For one thing, the LCD panel usually has its own brightness control, which, if not adjusted perfectly , may trick you into thinking a scene is better (or worse ) lit than it actually is. The color and exposure revealed by the LCD screen may not exactly match what's going onto the tape, either.

When picture perfection counts, therefore, use your camcorder's eyepiece viewfinder instead of the LCD panel. You may also want to use the eyepiece when it's very bright and sunny out (the LCD display tends to wash out in bright light), when you don't want people around you to see what you're filming, and when you're trying to save battery juice . The LCD display depletes your battery about 50 percent faster than when the LCD is turned off.

1.2.1.5 Electronic image stabilizer (EIS)

As you'll read in Chapter 2, certain film techniques scream " Amateur !" to audiences. One of them is the instability of handheld filming. In a nutshell , professional video is shot using a camera on a tripod (Woody Allen's"handheld" period not with standing). Most home camcorder footage, in contrast, is shot from the palm of your hand.

A digital or electronic stabilizing feature (which may have a marketing name , such as Sony's SteadyShot) takes a half step toward solving that problem. As shown in Figure 1-5, this feature neatly eliminates the tiny, jittery moves present in handheld video. (It can't do anything about the bigger jerks and bumps, which are especially difficult to avoid when you're zoomed in.) It also uses up your battery faster.

1.2.1.6 Optical image stabilizer

On some camcorders, you get an optical image stabilizer instead. This mechanism involves two transparent plates separated by a special optical fluid. As the camera shakes, these plates create a prism effect that keeps handheld shots clearer and steadier than many electronic (digital) stabilizers. The images are clearer because optical stabilizers don't have to crop out part of the picture as a buffer, unlike the stabilizers illustrated in Figure 1-5.

1.2.1.7 Digital8 format

Here's another plan for getting your older footage into iMovie: Buy what Sony calls a Digital8 camcorder. This fascinating hybrid doesn't use the MiniDV videotapes used by all other DV camcorders. Instead, it accepts the less expensive 8mm or, as Sony recommends, Hi-8 tapes.

Onto these cassettes, Digital8 camcorders record the identical DV signal found on MiniDV camcorders. But they can play back either digital video or traditional, analog video. (When recording digital video, however, the camera runs twice as fastyou still get only one hour of recording per tape, just as on MiniDV tapes.)

This kind of camcorder, in other words, is a good solution if you have a library of old 8mm tapes that you'd like to edit in iMovie. Your Mac can't tell which kind of tape the Digital8 camcorder is playing.

On the other hand, full-blown DV camcorders and tapes are no longer much more expensive than their 8mm predecessors, and Sony's Digital8 camcorder family has already begun to wind down.

Figure 1-5. Digital stabilization features work by "taking in" more image than you actually see in the viewfinder. Because the camcorder has some buffer, its computer can compensate for small bumps and jitters by keeping an "eye" on prominent features of the image. On less expensive camcorders, unfortunately, this buffer zone means that your camcorder is absorbing less video information, to the detriment of picture quality.

1.2.1.8 Manual override

Better DV camcorders let you turn off the automatic focus, automatic exposure control, automatic white balance, and even automatic sound level. This feature can be useful in certain situations, as you'll find out in the next chapter. If you've decided to pay extra for this feature, look for a model that lets you focus manually by turning a ring around the lens, which is much easier than using sliders.

1.2.1.9 Optical zoom

When you read the specs for a DV camcorderor read the logos painted on its bodyyou frequently encounter numbers like "12X/300X ZOOM!" The number before the slash tells you how many times the camera can magnify a distant image, much like a telescope . That number measures the optical zoom, which is the actual amount that the lenses themselves can zoom in. Such zooming, of course, is useful when you want to film something that's far away. (As for the number after the slash, see "Digital zoom," on the following page.)

You should know, however, that the more you've zoomed in, the shakier your footage is likely to be, since every microscopic wobble is magnified by, say, 12 times. You also have to be much more careful about focusing. When you're zoomed out all the way, everything is in focusthings near you, and things far away. But when you're zoomed in, very near and very far objects go out of focus. Put into photographic terms, the more you zoom in, the shorter the depth of field (the range of distance from the camera that can be kept in focus simultaneously ).

Finally, remember that magnifying the picture doesn't magnify the sound. If you're relying on the built-in microphone of your camcorder, always get as close as you can to the subject, both for the sound and for the wobble.

1.2.1.10 Digital zoom

Much as computer owners mistakenly jockey for superiority by comparing the megahertz rating of their computers (higher megahertz ratings don't necessarily make faster computers), camcorder makers seem to think that what consumers want most in a camcorder is a powerful digital zoom. Your camcorder's packaging may "boast" zoom ratings of "50X," "100X," or "500X!"

When a camcorder uses its digital zoomthe number after the slash on the camcorder boxit simply enlarges the individual dots that compose its image. Yes, the image gets bigger, but it doesn't get any sharper. As the dots get larger, the image gets chunkier, coarser, and less recognizable, until it ends up looking like the blocky areas you see superimposed over criminals' faces to conceal their identity on Cops. After your digital zoom feature has blown up the picture by 3X, the image falls to pieces. Greater digital zoom is not something worth paying extra for.

1.2.1.11 Minutes-remaining readout

Fortunately, the problems exhibited by camcorder batteries of oldsuch as the "memory effect"are a thing of the past. (When you halfway depleted a pre-DV camcorder battery's charge several times in a row, the battery would adopt that halfway-empty point as its new completely empty point, effectively halving its capacity.) Today's lithium-ion battery technology (used by DV camcorders) eliminates that problem.

Sony's InfoLithium batteries even contain circuitry that tells the camera how much juice it has remaining. A glance at the viewfinder or a small side-panel readout tells you how many minutes of recording or playback you've got lefta worthy feature.

1.2.1.12 Built-in light

As you can read in the next chapter, insufficient lighting is one of the leading causes of "amateuritis," a telltale form of poor video quality that lets viewers know that the footage is homemade. In the bestand most expensiveof all possible worlds , you'd get your scene correctly lit before filming, or you'd attach a light to the "shoe"(light connector) on top of the camera. Those few cameras that have such a shoe, or even have a built-in light, give you a distinct advantage in filming accurate colors.

1.2.1.13 Preprogrammed exposure options

Most DV camcorders come with a number of canned focus/shutter speed/aperture settings for different indoor and out door environments: Sports Lesson, Beach and Snow, Twilight, and so on. They're a useful compromise between the all-automatic operation of less expensive models and the all-manual operation of professional cameras.

1.2.1.14 Remote control

Some DV camcorders come with a pocket- sized remote control. It serves two purposes: First, its Record and Stop buttons give you a means of recording yourself, with or with out other people in the shot. Second, when you're playing back footage with the camcorder connected to your TV or VCR, the remote lets you control the playback without needing to have the camcorder on your lap. You may be surprised at the remote's usefulness .

1.2.1.15 Backlight mode

As you can read in the next chapter, modern camcorders take much of the guesswork out of shooting video. For example, they can focus automatically.

Although few consumers appreciate it, today's camcorders also set their aperture automatically. The aperture is the hole inside the barrel of your camcorder's snout that gets bigger or smaller to admit more or less light, preventing you from under or overexposing your footage. (Inside the camera is an iris a circle of interlocking, sliding panels that move together to reduce or enlarge the opening, much like the one in a still camera.)

The automatic aperture circuitry works by analyzing the image. If it contains a lot of lightsuch as when you're filming against a snowy backdrop or aiming the camera toward the sunthe iris closes automatically, reducing the opening in the camera lens and thus reducing the amount of light admitted. The result: You avoid flooding the image with blinding white light.

Unfortunately, there may be times when you have no choice but to film somebody, or something, against a bright backdrop. In those cases, as you may have discovered through painful experience, the person you're trying to film shows up extremely dark, almost in silhouette (see Figure 1-6). Now the background is correctly exposed, but the subject winds up underexposed .

A Backlight button, then, is a valuable asset on a camcorder. Its purpose is to tell the camera, "OK, look, it's a bright scene; I can appreciate that. But I'm more interested in the subject that's coming out too dark at the moment. So do me a favor and open that aperture a couple of notches, will you?"

Figure 1-6. Without the backlight mode, your camcorder is likely to turn your subject into a silhouette (left). The backlight button compensates by brightening everything up (right).

The camera obliges. Your subject no longer winds up too darkin fact, modern camcorders do a great job at making sure the subject turns out just right. But over- riding the automatic aperture control undoes the good the automatic iris originally did younow everything around your subject is several shades too bright. Alas, there's no in between; either your subject or the background can be correctly exposed in very bright settingsbut not both.

1.2.1.16 FlexiZone or Push Focus

All camcorders offer automatic focus. Most work by focusing on the image in the center of your frame as you line up the shot.

That's fine if the subject of your shot is in the center of the frame. But if it's off-center, you have no choice but to turn off the autofocus feature and use the manual-focus ring. (Using the camcorder isn't like using a still camera, where you can point the camera directly at the subject for focusing purposes, and thenbefore taking the shotshift the angle so that the subject is no longer in the center. Camcorders continually refocus, so pointing the camera slightly away from your subject makes you lose the off-center focus you've established.)

Some Canon, Sony, and Sharp camcorders let you point to a specific spot in the frame that you want to serve as the focus point, even if it's not the center of the picture. (This feature is called FlexiZone on the Canon models, or Push Focus on high-end Sony models. On Sony cams with touch-screen LCD panels, it's especially easy to indicate which spot in the frame should get the focus.) If the model you're eyeing has this feature, it's worth having.

1.2.1.17 Night-vision mode

Most Sony camcorders offer a mode called NightShot that works like night-vision goggles. In this mode, you can actually film (and see, as you watch the LCD screen) in total darkness . The infrared transmitter on the front of the camcorder measures the heat given off by various objects in its path , letting you capture an eerie, greenish night scene. Rent The Silence of the Lambs for an idea of how creepy night-vision filming can be. Or watch any episode of "Survivor."

The transmitter's range is only about 15 feet or so. Still, you may be surprised how often it comes in handy: on campouts, during sleepovers, on nighttime nature walks, and so on.

1.2.1.18 Still-camera mode

All DV camcorders offer a snapshot mode in which you can "snap" a still photo. The camcorder freezes one frame of what it's seeing, and records it either on the tape (for, say, a 7-second stretch) or on a memory card.

The still-image quality captured by most camcorders is pretty terrible. The resolution is OK on recent models (some camcorders offer two- or even three-megapixel resolution), but the quality isn't anywhere near what you'd get using a dedicated digital still camera. It turns out that the lenses and circuitry that best serve video are all wrong for stills.

If the camcorder you're considering offers this feature, fine. But it may be redundant for the iMovie owner. iMovie can grab one-megapixel still frames from any captured video, as described in Chapter 9.

1.2.1.19 Progressive-scan CCD

This special kind of image sensor is primarily useful for capturing still images. It ensures that the entire image is grabbed, not just one set of alternating, interlaced scan lines (the usual video signal). If you plan to catch still frames from your camcorder, a progressive-scan CCD will spare you some of the jagged lines that may appear. However, if your primary goal is to make movies, this expensive feature is not worth paying for, especially since you can buy a digital still camera, with much greater resolution, for about the same added cost.

1.2.1.20 Title generator

Some camcorders let you superimpose titles (that is, lettering) on your video as you film. In your case, dear iMovie owner, a title-generating feature is useless. Your Mac can add gorgeous, smooth-edged type, with a selection of sizes, fonts, colors, and even scrolling animations to your finished movies, with far more precision and power than the blocky text available to your camcorder.(Chapter 7 shows you how.)

1.2.1.21 Fader

Most DV camcorders offer a Fade or Fader button. If you press it once before pressing the Record button, you record a smooth, professional-looking fade-in from blackness. If you press it as you're recording, and then press the Record button again to stop recording, you get a smooth dimming of the picture (and, usually, a fading of the sound), all the way to black (and silence).

Even if your camcorder has a Fader button, don't use it, for several reasons:

• Pressing the Fade button in order to trigger a fade-out is very difficult to do. You're forced to look away from your subject to hunt for the button, and it's almost impossible to keep the camera steady in the process.

• iMovie offers much more graceful and controlled fade-ins and fade-outs. For example, you can specify exactly how many seconds long the fade should last, and you can even fade into a color other than black.

• When you use your camcorder's Fade button, you risk chopping off one last great wisecrack from your kid as she rides into the sunset, or one last backflip by the seal at Sea World. In other words, once you've started the fade, you can't stop it.

• If you need any more convincing, ask any camcorder owner about the embarrassment factor that comes from fading out on what he assumed would be the absolute perfect final shot, and then coming across another event that had to be included in the footage. When played back, the feeling of gentle, sighing finality created by the fade-out is jarringly shattered by the sudden appearance of that tacked-on scene.

1.2.1.22 Audio dubbing

In a few fancy camcorders, you can rerecord only the soundtrack on a piece of tape you've already shot. If you didn't have a Mac, you could conceivably use this feature to add, for example, an accompanying rock song to a montage of party scenes.

But iMovie offers far more flexibility in this department. For example, iMovie lets you add a piece of music to a scene without deleting the original voices, as your camcorder's audio-dub feature would. Don't pay extra for audio dubbing on your camcorder.

1.2.1.23 Special effects

Most DV camcorders offer a selection of six or seven cheesy-looking special effects. They can make your footage look solarized, or digitized, or otherwise processed (see Figure 1-7).

Figure 1-7. Using the stock collection of special effects built into your camcorder, you can create special, hallucinogenic visuals. The question is: why?

Avoid using these built-in camcorder effects; iMovie comes with a number of such special effectsand gives you far greater control over when they start, when they end, and how intensely they affect the video (Chapter 6). And even then, unless you're shooting a documentary about nuclear explosions or bad drug episodes , consider avoiding these effects altogether.

1.2.1.24 Date/time stamp

Every camcorder offers the ability to stamp the date and time directly onto the footage. As you've no doubt seen (on America's Funniest Home Videos or America's Scariest Cop Chases ), the result is a blocky, typographically hideous stamp that permanently mars the footage. Few things take the romance out of a wedding video, or are more distracting in spectacular weather footage, than a huge 20 SEP 05 12:34 PM stamped in the corner.

Nor do you have to worry that you'll one day forget when you filmed some event. As it turns out, DV camcorders automatically and invisibly date- and time-stamp all footage. You'll be able to see this information when you connect the camcorder to your Mac; then you can choose whether or not to add it to the finished footage (and with much more control over the timing, location, and typography of the stamp).

1.2.1.25 Control-L or Lanc

You'll find this feature on some Canon and all Sony camcorders. It's a connector that hooks up to special editing consoles.

You, however, have a far superior editing consoleiMovieand a far superior connection methodFireWire. Control-L and Lanc are worthless to you.

1.2.2. Where and How to Buy

Virtually every camcorder manufacturer has adopted the DV format, including Sony, Panasonic, JVC, Sharp, RCA, Hitachi, and Canon. Each company releases a new line of models once or twice a year; the feature list always gets longer, the price always gets lower, and the model numbers always change.

Cameras come in all sizes, shapes , and price ranges (see Figure 1-8). In magazine reviews and Internet discussion groups, Sony and Canon get consistently high marks for high quality. JVC and Sony make the smallest, most pocketable models. Still, each manufacturer offers different exclusive goodies , and each camcorder generation improves on the previous one.

Figure 1-8. The model lineup changes constantly, and new formats come and go. Here, for example, are three of Sony's digital camcorders.
