It is simpler than ever shoot high-definition (HD) video. This can be accomplished using traditional  camcorders, and also with cameras that designed to take still photos. Cameras that range from high-end “digital SLRs” to cameras that slip into your shirt pocket.

Here are 6 recommendations in all three categories from least to most expensive. All 6 of these record HD video and have “HDMI” output connections that let you view your video on an HD display.

Kodak Zi8 -  about $180

Full HD in your pocket for under $200

Kodak delivers this bargain by asking you to supply the memory card it needs to store footage.  8-gigabyte cards can be bought (enough for two hours of HD video) for less than $50, which means you could still come out ahead with this model over the other inexpensive HD cameras from Flip or Creative.

The Zi8 performed well, although its focus is fixed and it doesn’t have good depth-of-field for close-ups. It’s a little bigger than rival units, but still is comfortable to take on the go.

Creative VADO – about $230

The Creative VADO also fits in your pocket, but keeping it there is a waste. It’s just too much fun The VADO has 8 gigabytes of built-in memory and has a quality lens that performed well in low light. It comes with polished, easy-to-use software that allows for quick uploading of your video to YouTube and a few other hosting services.

It has a  recessed control button that was fairly intuitive to use. The footage it produced was near great. Jitter-free pans from left to right and good sound quality can be had from this camera.  It also comes with a proper rugged case to protect against accidental drops and bumps. The VADO is the best shoot-and-share out there.

Flip MinoHD  about $230

Flip has pretty much dominated its category with its easy-to-use video cameras. What sets them apart is their FlipShare software that is all about social networking. It allows for pain-free uploading to Facebook, MySpace and YouTube.

The latest model has backlit buttons that are flush with the shiny controls surface. This is awesomel in low light because you can’t really feel the buttons — although in low light the MinoHD’s video quality wasn’t  all that great.

There was difficulty in keeping a steady grip on the Flip on a warm day. Its sleek design is nice to look at, but it would be nice if it had few ridges or rubberized edges to hold on to. Buy it for the sleek software, but not because you think it will out-shoot others in this category.

Nikon S70  about $350

It’s compact and slickly designed. The LCD display on the back spans the width of the camera and gives you touch-screen access to the menus and settings. There’s really only one way to hold this camera while shooting video and that is with two fingers on the right edge of the camera and the pinky extended for high tea. Otherwise you will be likely to obscure the lens or trip the shutter button.

The image quality is passable for the price. It’s not the best performer in low light, but the colors held true in transitions from indoors to outside. It also stabilizes the image well while recording. That’s a big plus when trying to avoid that nausea-inducing shakiness that can render even HD footage unviewable. Once you find a comfortable way to hold the Nikon S70, there’s a lot of performance for the dollar.

Canon Vixia HF S11  about $1,400

This is a traditional style of video camera. There’s not a button, dial or contour out of place. It has a useful “hot-shoe” connection for external lights, microphones and other accessories. It zooms smoothly, with “image stabilization” that keeps you in focus. Its menu screens are so easy you can leave the manual in the box. For my money, this is the gold standard for the category.

Panasonic Lumix DMC-GH1  – About $1,500 with 14mm-140mm lens

Among digital SLRs tested, this was the strongest, most versatile performer. The Panasonic Lumix GH1, a 12.1 megapixel camera, delivered true hues and sharp images. It uses a design known as “Micro Four Thirds” in which the lens mount is positioned closer to the image sensor, without a flip-up mirror box in between. The result in this case is crisp HD video.

The GH1 has a flip-out LCD panel, which is easier for shooting video than fixed LCD panels, which can force you to strain or tilt your head as you shoot. From daylight scenes in a sun-drenched park to the glow of the fading evening light, the GH1 handled contrasts nicely. It has stereo sound and is a joy to use.
