A walk through today’s electronics emporiums, hotel rooms, and sports bars, as well as through a vast number of living rooms, reveals that we’re well on our way to reflecting reality in high definition. Broadcast television is going completely digital; HD movie downloads are becoming more common; and the large, analog cathode-ray tube TVs of old are about as relevant as the Model T. Given our increasingly high-def landscape, is it time to consider an HD camcorder?
In a word, yes. Prices for these camcorders have dropped precipitously—you can now put HD in your pocket for less than $200. Recent Macs have enough horsepower to edit the huge files these cameras can generate. And with each passing day, it’s easier to share the results of your work—in much of its HD glory—with the rest of the world. (Check out our latest camcorder reviews).
Features and functions
All HD camcorders have a lens, a sensor that captures video and converts it to digital information, an LCD that displays video, a storage medium, and a way to move video from the camcorder to a computer. But there’s variety in these elements, as well as in the resolutions and frame rates the camcorders can capture video in. Also, some models offer extra features that you might want to consider. Those elements and extras shake out this way (you can also check out our quick summary of what to look for in an HD camcorder):
Lens Full-size camcorders (as opposed to pocket camcorders such as the Flip MinoHD and Kodak Zi6) have lenses with optical zoom—the kind of zoom controlled by movement of the lens elements. All today’s full-size consumer camcorders have at least a 10x optical zoom. The image you get from an optical zoom is as crisp and clear as the lens can make it. In addition to optical zoom, these camcorders offer digital zoom that extends the reach of the optical zoom. (You could, for example, have a camcorder with a 15x optical zoom and a 180x digital zoom.) Digital zoom enlarges the image by making pixels larger, which leads to softer video (similar to scaling up an image in Adobe Photoshop).
Sensor At one time, digital camcorders contained CCD (charge-coupled device) sensors—imaging sensors that work in tandem with a separate processor to convert images to digital information. Most of today’s camcorders use CMOS (complementary metal-oxide semiconductor) sensors. CMOS chips are less expensive, require less power, and can be made smaller than CCD chips.
A sensor’s size and makeup can make a difference to your video. The larger a sensor is, the better its low-light performance is likely to be (so you’ll see less grain in video captured in low-light conditions). Also, the more pixel elements a sensor has (and the larger they are), the sharper the image usually is.
LCD Many modern full-size camcorders sport touch-screen LCDs you use not only to view your video but also to access a camcorder’s many recording and playback features. (Pocket camcorders have far smaller displays, and they have buttons rather than touch-screen controls.) On some camcorders, the LCD also acts as the sole viewfinder.
Storage Most full-size camcorders provide either tape-based or tapeless storage. And the way a camera stores its data hints at the kind of video format it uses.
Although tape is on its way out as a storage medium in HD camcorders, manufacturers including Canon, Sony, and JVC still make some tape-based cameras. These cameras shoot in the HDV (high-definition video) format, which uses the MPEG-2 compression codec, and they usually record onto standard MiniDV tapes.
Video from HDV camcorders looks great, and tapes can be convenient for archival purposes. The disadvantages of tape are that your shooting time is limited—a tape holds an hour of video—and unlike with tapeless camcorders, you don’t have instant access to individual clips. Instead, you have to wind through the tape to find the clip you want. Also, you have to capture footage from the tape in real time: if you shoot for an hour, it will take at least an hour to transfer all the footage to your computer.
Tapeless camcorders store their data on hard drives, flash memory chips, MiniDVD discs, or removable memory cards (and some cameras use multiple media). These cameras use the AVCHD (Advanced Video Codec High Definition) format—a high-definition format that uses the MPEG-4 AVC/H.264 codec.
When you import these AVCHD files into iMovie ’09 (or Final Cut Express or iMovie ’08, if you prefer), they are converted to the Apple Intermediate Codec (AIC) because iMovie can’t work natively with AVCHD footage. This conversion causes the file size to balloon—a 150MB AVCHD 1080i file converted to AIC weighs in at around 1.1GB. These AIC files consume a lot of storage space on your Mac, and editing them requires a fair amount of processing power—you need an Intel-based Core Duo processor or better. With the help of a video-conversion utility, you can convert AVCHD to a file format other than AIC, and you may be able to work with that converted file on a PowerPC Mac or a slower Intel Mac (we’ll have more on this later).
Camcorders that house a hard drive tend to be more expensive and bulkier than those that store data on flash media or media cards. The advantage of a camcorder with a 60GB or larger hard drive is that it can record for long periods of time. (You can get camcorders with hard drives that hold as much as 120GB.) For example, if you’re shooting a day’s worth of presentations and don’t want to miss a second to swap in new media, an AVCHD camcorder with a hard drive is a good choice. The disadvantage is that when the drive gets full, and if the camcorder doesn’t offer another storage option (a media card, for instance), you must either delete some of the data on the drive or connect the camcorder to a computer and archive the video, which can take time that you don’t have to spare.
Pocket camcorders act like USB key drives—connect one to your Mac, and it will appear on the desktop as a removable hard drive. These cameras store video either as H.264 MPEG-4 files (for instance, the Flip MinoHD, Kodak Zi6) or H.264 AVI files (the Creative Labs Vado HD).
Resolution and frame rate When looking at HD camcorders, you’ll see a variety of numbers followed by an i or a p—1,080i and 720p, for example. These figures indicate the HD video mode: the number of horizontal pixels and the display format. Specifically, 1,080 video offers a resolution of 1,920 (vertical) by 1,080 (horizontal) pixels; 720 video offers 1,280 (vertical) by 720 (horizontal) pixels.
The i and p stand for interlaced and progressive, respectively. Traditional video is made up of odd and even lines (or fields). With interlaced video, each video frame is displayed in alternate fields, horizontal lines that are painted on the screen from top to bottom. So in the case of 1,080i, the 540 odd fields of one-pixel rows are displayed first, followed by the 540 even rows. Progressive video (often called Full High Definition Video by manufacturers) draws every line, from top to bottom, in one pass.
The goal is to produce 30 frames per second (or darned close to it). Camcorders that shoot 1080i do this by shooting 59.94 interlaced, odd and even frames per second. This is termed 60i. 1080p camcorders shoot 30 (30p) progressive frames per second.
Some camcorders can optionally shoot 24p video—24 frames of progressive video per second. Because 24 fps is the standard used in motion pictures, shooting at this rate on a camcorder gives the video a more cinematic look. And because the shutter speed is lower (so more light can touch the sensor), 24p also gives you better low-light video. Additionally, video shot at 24p contains fewer frames and therefore consumes less storage space.
Progressive video looks cleaner than interlaced video, particularly when there’s a lot of movement in the image. You’re less likely to notice the difference between interlaced and progressive video on a television because TVs are designed to account for interlaced video—they either support interlacing natively (standard-definition TVs) or include deinterlacing circuitry (HDTVs) that converts interlaced video to progressive video. Computer monitors, which are progressive-scan devices, don’t include deinterlacing, which is why interlaced video can look jagged on them.
For this reason, it’s important to consider where your video will eventually appear. If that’s a TV, either interlaced or progressive video will do. If your video is likelier to appear on computer screens, progressive is the better choice.
Midpriced full-size camcorders typically shoot in 1080i, whereas more-expensive camcorders offer 1080p video (and some offer additional shooting modes such as 24p). Pocket camcorders, however, shoot only in standard definition or 720p.
Bit rateBit rate describes the amount of information stored in a unit of time. For example, HDV, which uses the MPEG-2 encoder, offers a maximum bit rate of 25 Mbps (megabits, or millions of bits, per second). AVCHD, which uses the H.264 encoder, maxes out at 24 Mbps. The higher the bit rate, the better the video should look.
You can’t compare the bit rates of different encoders, as each encoder has its own way of processing video. For example, H.264 is a more efficient encoder than MPEG-2, so it produces better-looking video at lower bit rates. When comparing camcorders, you can compare the bit rates of two AVCHD camcorders, for instance, but not of an AVCHD and an HDV camcorder.
Media transfer Today’s camcorders routinely transfer data via a USB 2.0 connection. This is good news for people with one of the most-recent MacBook models, which lack a FireWire port. Unlike full-size camcorders, which include mini-USB ports, pocket camcorders have full-size USB connectors. A push of a button usually releases the connector so it’s ready to plug into a USB 2.0 port. For cameras that use removable media—an SD card, for example—you can optionally eject the media from the camera and plug it into a card reader attached to your Mac.
Inputs and outputs In addition to a USB port, HD camcorders can include a variety of other ports for moving audio and video in and out of the camera. Mini-HDMI ports for connecting the camera to an HDTV or an HD receiver are commonly found on full-size HD camcorders. You might also find an AV-out port that lets you send component analog video to an analog device such as a TV set, a video recorder, or a video-capture card. Many full-size camcorders also include microphone and headphone ports.
Image stabilization Even if you don’t load up on caffeine, your hands are going to shake when holding a camcorder. To take the resulting shake out of a camcorder’s video, manufacturers include image-stabilization technology in their full-size camcorders. It can’t do much for wild movements, so it’s no substitute for a tripod—but it will smooth out the mild shake you commonly get when holding a camera. When you zoom in all the way, image stabilization makes it easier to frame your shot and hold it steady. Pocket camcorders don’t include image stabilization, so the video they capture is likely to be shaky unless you use a tripod or have unearthly muscle control. (As with zoom, optical stabilization is preferable to digital stabilization.)
Still capture Full-size camcorders can also take still images, just like a digital camera (some can do this while you’re shooting). Cameras will rate their still-image capabilities by the number of megapixels captured—3.0 megapixels, for example. While having the ability to capture still images is nice, it’s not these cameras’ strongest feature and therefore shouldn’t be a major factor in your buying decision. Most of today’s point-and-shoot cameras will produce better-looking pictures than a camcorder (and camcorders usually produce better looking videos than still cameras with video functionality, although there is a new crop of still cameras that can shoot HD video). Of the pocket camcorders, only the Kodak Zi6 captures still images.
Manual control While camcorders are normally operated as point-and-shoot devices, there will be times when you want greater control over exposure and focus—for example, if you’re shooting on a bright sunny day and want the camera to compensate with a more sympathetic white balance, or if you’re shooting in low light and the camera’s autofocus doesn’t track your subject as well as you’d like. The ability to select a white-balance setting, adjust exposure, and manually control focus is handy. The more expensive a full-size camcorder is, the greater manual control you’re likely to get. Pocket camcorders truly are point-and-shoot and offer no exposure or focus controls.
HD camcorders come in different sizes and prices—some are small enough to fit in a pocket and can be had for around $200; then there are full-size 1,080p wonders that will set you back a thousand dollars or more.
Pocket camcorders The poster child for the pocket camcorders is Pure Digital Technologies’ $230 Flip MinoHD (). But the Flip isn’t the only pint-size and inexpensive HD camcorder. You can also put HD in your pocket with Kodak’s $180 Zi6 () and Creative Technologies’ $230 Vado HD ().
These camcorders are dead simple to operate, have a small LCD display for viewing your subject and the movies you’ve shot, connect to a computer via a built-in USB connector, and shoot in either standard definition or high-definition 720p. The Flip MinoHD and Vado HD use an internal rechargeable battery (the Vado’s is removable), while the Kodak Zi6 runs off two AA batteries. Having removable batteries is handy when your battery runs dry and you don’t have access to a powered USB 2.0 port for recharging the camera.
The Kodak Zi6 also includes an SD/SDHC media slot, so you can load the camera with up to 32GB of storage. (The Flip MinoHD has 4GB of built-in memory, and the Vado has 8GB of memory.) You can connect all three camcorders to a television via a video-output port. The Flip HD supports composite video-out, the Kodak Zi6 can use composite and component video, and the Vado HD works with composite and HDMI connections.
Each camcorder’s display is a different size. The Flip MinoHD’s display is the smallest, at 1.5 inches. The Vado HD’s screen is 2.0 inches. And the larger Kodak Zi6 has a 2.4-inch screen. Their lenses are also different. The Vado HD’s lens captures a wider image—so from the same distance, you’ll capture more of a scene on the Vado HD than you can with either the Flip or the Kodak camcorder.
All three come with editing software, but only the Flip MinoHD has Mac-compatible software. Given that most Mac users edit video with iMovie, however, the lack of Mac software for the Creative and Kodak cameras isn’t a huge concern. (You must install the free Perian open-source QuickTime component to work with the Vado HD’s AVI files.)
Convenient and affordable though these pocket camcorders are, they’re limited in important ways. As mentioned earlier, they include only a digital zoom and lack image stabilization. The CMOS sensors and lenses aren’t of the highest quality, and white-balance settings aren’t adjustable. Each of them has color and light quirks. The MinoHD’s video shot under indoor lighting is very warm (yellow). The Vado HD’s outdoor shots tend to be a little oversaturated. The Kodak Zi6 will blow out yellows, reds, and oranges under certain kinds of direct sunlight (sunsets, for example). And low-light performance is bad across the board.
Even with these limitations, pocket camcorders offer some advantages. Primarily, because they’re so portable, you’re far likelier to be able to use them spontaneously. Also, their 720p nature—the progressive video that looks good on a computer monitor—makes these the perfect camcorders for shooting quick and dirty video you’ll post to a video-sharing service such as YouTube (see “Sharing Your Videos” for more on online hosting).
In between Nestled between the small, 720p pocket cameras and the full-size camcorders is Sanyo’s $710 Xacti VPC-HD1010 (). With its 10x optical zoom, its ability to record 1080p video, its 2.7-inch LCD, and its full complement of ports, it’s similar to larger camcorders in terms of its feature set. But with its compact, pistol-grip form factor and its light weight (less than 11 ounces), it resembles a pocket camcorder.
Full-size camcorders Over the past several years, the world of full-size HD consumer camcorders has been very confusing. HDV or AVCHD? Tape or tapeless (and which tapeless—MiniDVD, hard drive, or flash)? Progressive or interlaced? 720 or 1080? CCD or CMOS? Thankfully, some order is starting to come to this world.
Tape-based HD camcorders are on their way out—AVCHD is the future (if not the present). But tape isn’t dead yet: for some people, HDV’s quality trumps AVCHD’s convenience. Canon’s Vixia HV30 MiniDV HD () is a highly regarded camcorder that offers 1080p resolution and a 24p Cinema Mode, sports a load of ports (including HDMI, microphone, FireWire, USB, and analog video), and is available online for less than $600. A newer version of this camcorder, the Vixia HV40 HD, should be available by the time you read this. Sony hasn’t completely abandoned tape-based HD cameras either. Its HDR-HC9 MiniDV HD Handycam is still available for around $850 online.
[A] Many camcoders are available online for significantly less than the list price. [B] All camcoders listed shoot at 1,920 by 1,080 pixels unless otherwise stated.
Among AVCHD camcorders, the main players are Canon, JVC, Panasonic, and Sony (see “Full-Size HD Camcorders Compared” for details on several current and soon-to-be-released models). All the cameras listed are compatible with iMovie ’09, with some restrictions (see Apple’s iMovie ’09: Camcorder Support page for more information).
Each camcorder has a CMOS sensor—and iMovie ’09’s image stabilization doesn’t work that well with these sensors: according to Apple, applying image stabilization can introduce warping in videos. And for iMovie to work natively with the JVC and Sony camcorders’ AVCHD video, you must have an Intel Mac. Also, while the JVC and Sony camcorders can use both the MPEG-2 and AVCHD formats, iMovie doesn’t support the MPEG-2 files produced by these cameras. You can import them into your Mac, but you must convert them to another format (DV or MPEG-4, for example) to work with them in iMovie.
As mentioned, the size of a sensor can influence low-light performance, and that’s the case here. The Canon and Sony camcorders, with their approximately 1/3-inch sensors, produce better low-light results and detail than camcorders with smaller sensors. And a multitude of sensors doesn’t seem to help. The Panasonic camcorders, for example, have three 1/6-inch CMOS sensors (one each for red, green, and blue), and these cameras’ low-light results aren’t as good as what you get from the Canon and Sony models.
Of these cameras, only the Canon models offer 1,080p video—the others shoot at 1,080i—but both the Canon and the Panasonic cameras allow you to shoot in 24p. Both the Canon and the JVC camcorders offer a bit rate as high as 24 Mbps, and this shows in the clarity of the video these cameras produce. Optical zoom ranges from 10x, for the tape-based models here and the JVC HD40, to 20x, for JVC’s HD320 and HM200. Most fall in the 12x to 15x range. All the cameras include HDMI and USB 2.0 ports. Microphone and headphone ports, which for video podcasters and broadcasters are an absolute necessity, aren’t on all these cameras—JVC’s HD320 and HM200 and Sony’s CX12 lack them.
All these camcorders provide some way to manually control focus—but, regrettably, the easiest method, a manual focus ring, is less common than it once was. The Panasonic and Sony camcorders allow you to adjust focus with such a ring. The other camcorders rely on dials, touch-screen controls, or joysticks, all of which are more difficult to use when you’re fine-tuning. As for manually controlling other functions—aperture, shutter speed, and white balance, for example—the Panasonic cameras lead the pack.
