Road to High Def

HIGH-TECH projects often take longer to complete than anticipated; just ask Microsoft’s Windows team.

 

But it seems as if we’ve been hearing about high-definition video since the Eisenhower administration. The Federal Communications Commission’s mandatory cutoff of old-fashioned analog TV broadcasts, now scheduled for 2009, has been delayed, what, 500 times?

Part of the holdup is the extent and expense of the switch to the new, better-looking format. To achieve HDTV nirvana, you have to replace every element of your video setup: the TV set, cable box, DVD player, DVD movie collection — and even your camcorder.

Next month, Canon will release the world’s smallest and least expensive high-definition tape camcorder, a one-handable beauty called the HV10. Its list price is $1,300. As any gadget freak can tell you, however, that’s an inflated, fanciful figure provided for — well, for no good reason. The online price, once the camcorder is on store shelves, will be lower.

The HV10 is not the first high-def consumer camcorder by any means; Sony began blazing this path at the beginning of 2005. In fact, Sony’s third HD camcorder, not counting pro models, has been available for months: the HC3 ($1,500 list price; under $1,200 online), the previous price and size champ.

As Canon rolls out its HV10, Sony’s HC3 seems to be squarely in its cross hairs. Both camcorders produce video in the 1080i format, which you can edit in Apple’s iMovie or many Windows programs (Premiere, Vegas, PowerDirector and so on). Both have built-in, automatic lens caps but lack headphone and microphone jacks.

Both are HDV camcorders, which means that they record onto standard, easy-to-find, inexpensive MiniDV cassettes. The eyepiece viewfinder is immobile and nonextendable on both. And both cameras are so compact, the other parents at the baseball game will have absolutely no clue that you’re filming in high definition.

OF course, they’ll also have no idea that you paid more than $1,000 for your camcorder, compared with as little as $300 for a standard-def model — at least until they see the result on a high-definition TV.

That’s when they’ll see what all the fuss is about. The clarity, color fidelity and detail of good high-def video is absolutely astonishing, and its wide-screen shape makes even home movies look like Hollywood movies. With four times the resolution of a standard TV picture, high-def movies look like the view out a window.

This image-quality business, as it turns out, is the new Canon’s specialty. Talk about being blown away the first time you play back your recordings — let’s hope you have a sturdy couch.

Several advances are responsible for the brilliant picture quality. First, Canon has paid extra attention to two of the most important aspects of HD recording: focus and stability. Because the high-def picture is so sharp and so wide, moments of blurriness or hand-held jitters are far more noticeable and disturbing than in regular video.

So the front of the HV10 bears a special external sensor that, when you change your aim, handles the bulk of the refocusing extremely rapidly. A standard through-the-lens focusing system does the fine tuning after that. Together, these two mechanisms nearly eliminate the awkward moment of blurry focus-hunting that mars other camcorders’ output. (Take care to avoid covering the focus sensor with your fingers as they wrap around this vertically oriented, chunky camera.)

The HV10 also aims to iron out camera shake with a true optical stabilizer. A gyroscope inside the lens mechanism sends real-time feedback to the sensor itself, resulting, Canon says, in a more stable picture than you’d get from electronic stabilizers like the one in Sony’s HC3.

In practice, the Canon’s stabilizer works fantastically when you’re zoomed out; if you use two hands, the picture is indistinguishable from a tripod shot. As you zoom in, however, camera shake becomes more noticeable; at the 10X maximum, keeping the video rock-solid requires either a tripod or nerves of steel.

Now, depending on where the Canon’s street price winds up, Sony’s HC3 may be slightly more expensive. But it offers some goodies that the Canon lacks: a minutes-remaining readout for the battery; a “nightshot” mode for filming in total blackness, infrared-style; and an accessory shoe for video lights and microphones (proprietary Sony accessories only).

The Sony model also has an HDMI jack. HDMI is a single cable that carries high-definition video and audio — a common, extremely convenient connector on high-def equipment. Connecting the Canon to a high-def TV, on the other hand, requires plugging in five connections: left and right audio, and three component-video jacks.
