The GoPro Hero

The GoPro Hero Wide

Physical Characteristics:

The camera includes several mounting options, including a rubber headband that resembles a jockstrap. It’s not much to look at, but it’s also not going to be the common use (I hope) for most users. The camera mount on the “jockstrap” can easily be removed and connected to more substantial webbing. The water housing is impressive. Very impressive for the price, in fact. I’ve paid more for a cheap housing than for this entire camera, and this housing is more nicely built than a housing I once paid $350.00 for. This is a good thing, because the mount for the camera is integrated into the waterproof/protective housing of the camera. The system is not designed to be used without the camera in its waterproof housing.

The camera itself feels “plastic,” even though it is made of light aluminum and plastic. The plastic lens is fairly exposed; all the more reason to keep it in its waterproof case and keep the case in a soft bag when not being used, in order to protect the lens from damage/scratching.

This shot was one of 92 still images captured in a single skydive.

With a plastic pressure-release mount, there is some fear that a hard strike will cause the unit to be torn from whatever mounting device it may be attached to; this is a positive feature rather than negative factor, as safety is the primary concern of all active sport enthusiasts.

The plastic mounts are plentiful; GoPro provided three stick-on mounts with extra double-sided adhesive material. In addition, GoPro provides a pair of extra mount clips,  and  a mounting arm that allows for a 90degree rotation of the camera when mounted to vertical objects such as the mast of a kiteboard, paraglider, or similar. It’s much like an Israeli-arm used for higher end cameras, excepting that it’s exceptionally lightweight, and plastic.

The camera comes with several mounting devices/replacement parts.

Technical Characteristics:

The camera has a very small sensor size, I believe it is 256 x 192 with doubling, but I was unable to receive confirmation of this from the relations department at GoPro. The sensor is a CMOS imager, which is somewhat obvious by the lack of dynamic range (see image with large black spot in center of sun).
Sporting an output  frame size of 512 x 384, broadcast, output to DVD, or other full-frame display will be difficult to do with any degree of image integrity. For web or fun review on a computer in small viewer, it's perfectly appropriate and will give a lot of enjoyment to the sports enthusiast that isn't chasing professional results.

GoPro encodes to an MJPEG codec in AVI container (will be .mov on Apple) and will require an MJPEG decoder in order to read/edit. Most NLE software includes an MJPEG decoder, and they are available from several providers around the web. The encoder compresses the video data to 4800 Kpbs, which is approximately the same compression ratio found on many hllywood DVDs. However, bear in mind that Hollywood DVDs are framesized at 720 x 480, and are sourced from film or HD cameras. I mention this, as some of the marketing commentary on the GoPro Hero compares technical data with that of a DVD. They’re not remotely the same. Additionally, DVDs are encoded with a PAR (Pixel Aspect Ratio) of .909 or 1.333. This means that pixels are elongated in either a horizontal or vertical configuration. The GoPro records a PAR of 1.0 (this means the pixels are square, and are not stretched, which is a benefit). The display is a Standard Aspect Ratio, otherwise known as 4:3. This is the “old” format of screen display, and is no longer available in television displays.  GoPro might consider providing widescreen in an anamorphic format in their next camcorder models, as widescreen displays are now the world standard.
30Fps Progressive frames means the image will be smooth for playback, and clear on computer monitors.
Audio is recorded in Mono @8Khz/64Kbps stream. The audio is useless for anything other than reference. It should be pointed out once more, that this camera is aimed at the sport enthusiast that wants to capture exciting moments for the web, not for broadcast or professional use.

Still images may be captured at the rate of one still every two seconds for up to 65 minutes (over an hour) on a 2GB SD card. Larger cards may be used. The stills are 5MegaPixels, and for some, this is going to be a “wow” factor. However, there is a difference between stills captured through a low-cost plastic lens and a reasonable quality glass lens as found on most 3-5MP hand cameras. In other words, the megapixel count is only a small part of the actual picture quality. (More megapixels don’t assure better pictures in any event.)

SD flash card is the format in which this camcorder stores data. SDHC cards do not improve the performance, speed, nor quality of the camcorder.

The camcorder package also includes a proprietary cable connection that outputs to USB and video composite signal.

Note the hot-spot in the middle of the sun. I was able to consistently reproduce this artifact with any bright light source in a high latitude shot. Even a 100 watt lamp could create this anomoly in a reasonably lit room. I believe this is a problem with the sensor; it cannot manage high latitude.

Operational Characteristics:

The camera is easy to operate. The multiple-press menu button that provides an icon-driven LCD panel doesn’t provide immediate feedback, and requires a review of the owners manual to decode the iconography of the display. In my first operation, I captured video from a skydive, but accidentally deleted the files as a result of not being clear on what the different icons were indicating.

Additionally, it wasn’t immediately clear on how to turn off the camcorder, and when left on without operation, the camcorder eats batteries fairly quickly. With regard to batteries, only Lithium batteries should be used with the GoPro Hero. They’re a little more expensive, but this device eats alkaline batteries like they are candy. Rechargeable batteries may not be used.

The GoPro Hero Wide uses SD memory cards. The black strip on the back is a rubber isolator to keep the camera tight in the waterproof housing.

There are only two buttons on this camera, it’s not like it’s a challenge to operate once the owners manual has received a glance or two. One button for shutter control/record functions, and one button for menu control. The beauty of this camera is found entirely in its small size, price, and ease of use.

Summary:

This camcorder isn't going to light the professional's eyes up like a professional POV camera will, but it won't burn the amateur's wallet like a professional POV camera costs, either. I've tried all the various POV "sport cams" currently on the market, and for sub $200.00, this is clearly the winner. There simply is no camera in its class that can compete. GoPro should be proud of themselves for designing a camera with this quality in this price range. At $189.00 it certainly isn't a toy, but it is a very fair cost of the fun this camcorder can record for the sport enthusiast. Mounted to handlebars, helmets, struts, pedals, forks, kayaks,  paddles, fenders, wrists, feet, belly, or other body part, the GoPro Hero is a hit in my book.
