GoPro HD HERO2 Review


The new GoPro HD HERO2 has quite a few excellent features on top of its already outstanding functionality, the most prominent being the 11 megapixel sensor, which is accompanied by a sharper glass lens, both of which result in photos and videos with increased clarity and sharpness, and more vibrant and realistic colors. The UI or menu system, has been revamped, and now has a simpler and more intuitive language-based interface, greatly easing usage. The camera is encased in their waterproof and durable housing, and has a plethora of mounting accessories, so that it can be attached to just about anything. It records in a vast array of high-definition video resolutions, frame rates, and viewing angles, making for an incredibly versatile camera.

HD HERO2
GoPro’s HD HERO2 is a POV (point of view) high-definition sports camera, and uses an 11MP HD CMOS (complementary metal-oxide-semiconductor) sensor, which is 1/2.3" in size. It uses a fixed-focus lens, which is made with professional-grade glass, and has a f/2.8 aperture. It can record video footage in 1080p, 960p, 720p and SD formats, and photos in several modes. It records data onto SDHC cards (not included) up to 32GB in size, and is powered with an internal rechargeable Li-Ion battery that gives around 2.5 hours of recording time. It has ports for a mini USB for computer connection and recharging, a mini HDMI and composite video for live streaming to a TV or other source, and an external microphone for higher-quality audio recording. The small and light camera is mostly made of plastic, and is encased within a tough and robust polycarbonate waterproof housing, which protects the fragile camera from impacts, shocks, and the environment. The housing attaches to an assortment of mounts, including a seatpost, curved and flat surface, wrist, tripod, vented helmet, and handlebar, and others, and usually snaps into the mounts using their proprietary quick-release buckle. It's compatible with all of their expansion accessories and BacPac's, and comes in three versions or kits, the Outdoor Edition (as tested), the Motorsports Edition and the Surf Edition, which all retail for $299.99.


The HD HERO2 Outdoor Edition kit comes with the HERO2 camera and waterproof housing, a slotted backdoor, a rechargeable 3.7V 1100mAh Li-Ion Battery, a USB cable, a vented helmet and head strap (aka the jock strap), two curved and flat surface mounts, a three-way pivot arm, an assorted mounting hardware and a user manual. It's convenient that the HERO2 has the same size and form factor as the current HD model, so the housing, mount systems, and BacPac's are all interchangeable.

Palmer Park TGap Trail - GoPro HERO2 720p Full Light Test:



Video
The HD HERO2 can shoot in High Definition, in four video resolutions, which are all recorded at 11MP. It can shoot in widescreen 1080p at 30fps (frames per second), full frame 960p at 48 fps or 30 fps, widescreen 720p at either 30 fps or 60 fps, and SD at 120 fps or 60 fps. The 960p 48fps, 720p 60 fps and SD 120 fps allow for slow motion playback, which is pretty interesting to watch, and in addition; it gives normal viewing a smoother and more fluid stream. Each of the video resolutions is captured at different bit rates, which entails varying recording times and storage requirements, meaning greater resources are needed for in the higher usage formats. The resolution settings are done within the camera's menu system, which is managed by its two buttons. In fact, any of the programmable features and settings can be done through the menus, allowing for the field changes as required. The camera records in different viewing angles or FOV (field of view), including an ultra wide 170º, a wide 127º, and a narrow 90º FOV, and each of them is unique to specific video resolutions. The 1080p has three FOVs, 170º, 127º and 90º, while the 960p , 720p and SD only use 170º. Supposedly, GoPro will be releasing a firmware update to allow a FOV of 127º for 960p and 720p? It uses the H.264 video codec, AAC audio compression, and a .mp4 file type. Everything defaults to the NTSC standard, but it can optionally record PAL video in 25fps and 50fps increments.

 
Photos
The HD HERO2 can shoot still photos in manual, self-timer and time lapse modes. In the manual mode, it can be set to shoot a single photo or do a burst of ten photos in 1 second. The self-timer mode just takes a single photo after doing a 10-second countdown. The automatic time lapse mode allows photos to be taken every X number of seconds, where X is 1/2, 2, 10, 30 or 60-second intervals. The megapixels for photos can be set to 11MP with a 170º FOV, 8MP with 127º, and 5MP with 170º or 127º. The 11MB sensor gives some really nice pictures with a lot of clarity and sharpness, and makes the photo feature a lot more useful. The ability to do some sports specific action shots with the 1/2 second time-lapse, and ultra fast 10 shot burst, should provide for some interesting shots and more versatility.


Camera Features
On the front of the HERo2 is the power/mode button, which turns the camera on and off, and makes changes for its recording modes and setting's menu. It works in junction with the top located shutter/select button, and together they perform all the cameras modal and setting changes. The shutter/select button starts and stops the video recording, initiates picture taking and does selections in the menu system. There are four LED recording lights, located on the front, back, top and bottom, which quickly flash when turning the camera or recording on and off, and they'll slowly pulse during actual recording. On the back is the connection port for their optional BacPac's, and a pop off door for accessing the battery.

The front LCD status screen displays a variety of icons, numbers and language-based data, which gives mode information, menu items and camera configuration settings.


There is a small speaker located on the bottom, which beeps during shutter and power initiation, and a microphone on the top that picks up audio. On the left-hand side, there's the SD card slot and mini HDMI video port, while the right side has the USB and composite video and external microphone connections.

Memory/Storage
It takes SDHC (Secure Digital High-Capacity) cards up to 32GB in size, and class 4 or higher are recommended, and if you are taking burst of ten photos or 1/2 second time-lapse, then a class 10 cards are required. The SD Cards are formatted with a FAT 32 partition, which has a 4GB file size limitation. While recording, a new video file will be created once the currently recording one reaches appropriately 3. 84GB, due to the FAT (File Allocation Table) limitation, so you will need to piece the files together in an editor to have a full timeline.

Battery
The camera uses an internal rechargeable Lithium Ion 3.7V 1100mAh battery, which is charged using a computer USB port for its replenishment, and there is an optional car charger. The battery fits very snugly into the rear slot, so that it won't give any issues with high vibration activities, like mountain biking, but it does make it tougher to extract for swapping purposes. The battery is supposed to last 2.5 hours per charge, but it varies depending on the temperature and chosen video resolution, and with 1080p I got 2.2 hours, while 720p gave me 2.4 hours. The battery also operates a warmer, which helps the battery life in colder temperatures, and the extended service was quite noticeable on rides below freezing. There is an optional battery BacPac, which gives twice the battery life, but I haven't tested it for verification of any statistics. I always carry a spare battery on any rides, just in case of any unforeseen issues. I have forgotten more than once to recharge the battery after use, and it's a bummer to get out in the field without an extra.


Housing
The clear plastic housing is a nice unit, that is rugged, durable, resists contamination and is waterproof to 60 meters/197 feet. The housing is made of polycarbonate and has a replaceable front lens, and a door that swings on stainless steel hinge pins. The back door has a tough waterproof gasket and is removable, so that the optional slotted skeleton door can be installed for better sound quality, with an obvious loss of waterproofness. Once the camera is placed in the housing, close the door and hook the latch on it, and clamp it down tight. I have used the camera kayaking, and biking in the rain and mud, and can attest to its tight seals and the protection it affords. On the bottom of the housing is a two toothed or slotted connector, which attaches up to their mounting system or quick-release buckle via a thumb screw. The housing has two springs loaded buttons, which interface to the camera's shutter/select and power/mode buttons, so all camera functions can be accomplished from the outside. Although it's tough, the bubbled out lens can get scratched, albeit it's at least replaceable. The closure latch can be temperamental sometimes, and either not work or pop out of place.


User Interface/LCD Status Screen
The new UI menu system is worlds ahead of its predecessor, and the old cryptic mode and status icons have given way to an intuitive and easier to understand the setup. When I first got the test unit it had no manual, yet I could poke my way through the menu hierarchy, and choose the proper video resolution, and get the date setup. The LCD screen is where you see the current status, such as the battery level, video or photo resolution settings, shooting mode (video, photo, burst, time lapse, timer), picture or video count, etc. As you navigate through the menu system, using the power/mode and shutter/select buttons, various icons, numbers and language are highlighted on the LCD screen, allowing multiple camera options and parameters to be set.

The power/mode button moves you linearly through the camera mode screens, which include the video, photo, burst, time lapse, timer and finally settings, which allows entrance to the menu system to change the camera's configurations. Within the setting's menu, you use the power/mode to move through the main screens, and use the shutter/select to go into a subscreen, and use the power/mode to move through the parameters in the subscreen, and shutter/select to accept the change. Using the combination of the two buttons in that manner, any allowable configuration permutation can be obtained.

The new UI is really nice, and makes it easy to make changes without having to resort to the user manual. It's still a bit cumbersome and too linear in its usage, and isn't quite up to the UIs of normal cameras, but it's a grand sweeping change from the previous cryptic interface. I think what you see on the main mode screens when not in the configuration system is the handiest, and provides very pertinent information, such as an actual numeric video mode value and its fps, recording mode icons, along with a remaining battery count and SD card resources.


Camera Operation
Before using the camera, charge the battery if required, and insert an SD card in the camera's slot. To turn the camera on, just push the front power button, and it announces itself with three beeps and LED flashes. After choosing the desired resolution and recording mode from the menu system, you push the top shutter button to start the recording. The camera beeps once, and the indicator lights begin to pulse or blink. To stop the recording, push the shutter button again, and it beeps three times, and the lights stop blinking. I did appreciate the increased volume level of the beeps compared to its predecessor, as they are now loud enough to hear over environmental background noise. To turn the camera off, press and hold the power button for 2 seconds, and it will shut down, ending with seven quick LED flashes and beeps.

When you're using the helmet mount, it was difficult to know if it was actually recording, and the only method to verify its operation was to remove your helmet and see the recording lights or status screen. When mounted anywhere else, the new additional indicator lights assist with ascertaining its operational mode. Cameras with a more mechanical on/off lever, such as the Contour, alleviate that issue. Another point of contention, is that it's sort of hard to know what you are capturing on the unit, so you have to use the camera body alignment, or use the optional LCD BacPak and eventually the smartphone to Wi-Fi BacPac interface. Depending on where the camera is mounted, you can use the LCD to align the viewpoint or record a short video, and play it back to check what you were capturing, and then make any tuning alterations. Like many of the mini monitors, the LCD was difficult to use in bright light, and you sometimes had to look at in the shade or cover it from direct light for viewing. I found the additions of the new louder modal beeps and four led indicator lights to be highly beneficial to the form factor of the unit, and greatly assisted knowing its current operational status.

Interface to Computer
To download or view the videos or pictures you recorded, take the HERO2 out of the housing, and using the supplied USB cable, connect the mini USB to the camera and the other end of the connector to a computer USB port. The unit will appear as a Removable Disk, and just navigate down to the appropriate directory (example: F:\Removable Disk\DCIM\100GOPRO) and either download or view the video straight from the camera. For faster downloads, use a standalone SD card reader, and bypass the camera as the downloading interface. The recorded footage can also be viewed on a TV by using the HDMI or composite video ports of the camera, using the buttons to tab through, and start each of the video's stored on the SD card. The controls are very rudimentary, but the results are quite impressive on a larger screen.


Mounts
In the grand scheme of things, GoPro has the best mounting system and the largest assortment of mounts of the sport POV camera manufacturers. They are extremely functional, and allow placement in just about any location desired. The mounts, adapters and swivel arms can be set up to shoot a lot of variations, attachment points and viewpoints, making for some interesting footage. Everything fits together like a small tinker toy set, with clamping and connection done by a plastic ended screw with a nut, which are tightened by hand or screwdriver. The housing can be attached directly to the quick-release buckle or the arms, and the assortment of mounts for biking includes a seatpost/handlebar, curved and flat surface, tripod, vented helmet, and others. I predominately tested with helmet placements, which included the vented strap and stick-on surface mounts. It does give the footage a sort of floating in space viewpoint, but it was my preference. I occasionally used the optional seatpost/handlebar mount and chest mounted harness (aka The Chesty), the latter giving a unique vantage point. The "Chesty" was pretty cool, and was excellent for skiing and kayaking, where it ruled. I didn't like it as much as most people, since I tend to move around too much, and the saddle and other things got in the way. The handlebar mounts gave an interesting perspective, and it kept the camera out of my way. The seatpost setup was less than ideal for me, as I tended to snag the camera when I hung out over the rear of the bike. The quick-release buckle system just plain rocks, and it's so easy to take the camera on and off, as all it requires is a quick backwards push of the buckle into any of the mounts.


Overall, the quick-release buckle is a well-thought-out unit, and it snaps into any of their mounts, making it universal throughout their product suite. Sometimes this system can be sloppy, allowing the unit to flop vertically on its axis, but it be remedied by using the vibration or locking plug (aka the nose plug) or adding some strips of electrical tape on the mount's slider surface.


The mounts can also be tough to tighten down properly without resorting to a screwdriver, although roughing up the shiny arm joints with sandpaper help somewhat. Even after doing the workarounds, the camera can creep around during a ride, or get hit accidentally and move out of position, ruining subsequent recorded footage. The toaster shape of the housing means it's tubby, and not streamlined nor svelte in any manner, so it can get easily caught on things, and it seems to suck tree branches into its vortex! You quickly learn to check the camera on occasion to make sure it didn't go out of position, especially after going through the trees or if your head got whacked by a branch.


Expansion Port/BacPak's
The back of the camera has an expansion port, that will allow optional expansion packs, or BacPac's to be connected, which extend the functionality of the camera. The current BacPac list is an LCD screen to view videos/pictures, and a battery extender. The BacPac kits come with the BacPac and an expanded back door, so that the fatter camera (camera with attached BakPac) will fit inside the housing. To install it, just hook one end of the BacPac onto the camera, and insert it into the expansion port. Pop off the housing's door and replace it with the BacPac's expanded waterproof or skeleton door, depending on your requirements, and you're ready to go. The soon to be released Wi-Fi BacPac will allow live video streaming and remote control, through smart-devices, computers, etc., opening up a plethora of features and functions.

Impressions
After using the camera, you become spoiled by the 11MP sensor and sharper lens, and in comparison to all other manufacturers, the footage has better clarity, colors and sharpness. Suddenly, the competitors seem antiquated, and the word that comes to mind is vividness. It’s like cleaning the dirty windshield of your car, and everything just pops out in a razor like contrast. Sometimes when bumping up the pixel count into an extremely small sensor, the increased pixels per inch (PPI) or pixel density can cause noise and loss of detail issues, and the sharpness drops off, but that doesn’t seem to be the case with the HERO2. The sensor is also much better at lower light conditions than its predecessor and the competition, although the camera still has no features to change the internal lightning settings, for more extreme low-light conditions. It did well in bright light conditions, and never seemed to wash out, keeping a nice uniform contrast level. Like many of the CMOS sensors, straight-on sun will cause some vertical colored bands and flares. Pixelation was great, with a mild amount of aliasing, and some slight edge artifacts. The framing was smooth, but heavy shocks, and vibrations caused distortion. Although the colors were pleasant, they were sometimes overly warm, and the reds and yellows were especially more vibrant than real.

The improved 11MP sensor and lens also gives some really nice photos, and I started to use the photo features more often. You can switch the photo mode to the lower 8MP and 5MP settings, which do have different FOV's (8 is 127º, 5 is 170º or 127º) , but you miss out on the stunning pictures at the highest setting.

The 1080p video footage had less jellovision and shakiness than earlier models, but I still don’t like its results when recording in average mountain biking conditions and terrain, even when wearing a sturdier helmet. The new 127º and 90º FOV options for the 1080p offers decreased fisheye and side distortions(default is 170º), but it seems to drop some clarity. When it was static or mounted as solid as possible it offered excellent FOV and clarity, but that just wasn't feasible for average riding.

Rattlesnake Trail - GoPro HERO2 1080p




My favorite setting was the full frame 960p 48 fps resolution, as the tall viewpoint captures more of the trail, and the addition of the 48 fps really gives it a smoother look, with fewer transitions and choppiness. My secondary pick is the widescreen 720p at 60fps, which depending on the terrain and trail, offers more peripheral visibility and a panoramic field of view. I did most of my testing with 720p 60fps since it was the easiest resolution to use to test against the competition, such as the Drift HD, Replay XD, Contour+. The camera didn't seem to do quite as well as it's predecessor in mixed light, where the unit was going in and out of bright light to shade, although it was more than adequate, but had too much wash outs.

Blackjack Trail - GoPro HERO2 960p 48fps: Mixed Light Test



When I used the camera in the low light of late afternoon and evening, it really captured the nuances of the terrain, without any dark dropouts. This characteristic was a real highlight for me, as I ride lots of heavily wooded trails and during near dusk conditions, and dislikes coming home and finding that I captured poor footage. Once it starts to get much darker out, the lack of adjustability for lighting conditions can cause issues, since there aren't any capabilities to change the contrast or exposure settings, but I rarely shoot in those conditions, so it was a minor issue.

Broken Hip Trail - HERO2 960p 48fps: Different vantage points



I liked the handlebars or the helmet mounts myself, which worked the best for my riding style, and also gathered footage that I preferred. With the vast assortment of mounts, you can come up with some unique footage and viewing angles, and perspectives, which make for more pleasurable and interesting videos (meaning less boring). The Chesty harness certainly adds flavor to footage, and I did use it on occasion for variety. I have become quite lazy after countless hours of recording video footage, and I'm not as industrious and inquisitive as I once was in taking and getting unique and varying perspectives. Consider my default helmet approach as plain Jane, lacking ingenuity, but at least conveying the camera's capabilities and the trails that I am riding technicality and beauty.

I loved the loud new beeps, as it really makes it easy in typical outdoor conditions (noisy) to hear what the camera is doing. Along with the louder beeps, the additional recording LEDs greatly benefits the form factor of the camera, making it much easier to know its status. I am looking forward to having the Wi-Fi BacPak, since the current system to check what you're capturing is a pain (using the LCD or aiming the housing), and problematic, especially when using a helmet mount. In addition, it will allow camera configurations changes to be accomplished using a smart phone, instead of the camera menu. The menu system is much improved, but it is still convoluted and much too linear for quick changes, especially to switch resolutions, but at least the main mode screens offer excellent information, so you know the exact resolution, FOV, battery and SD card resources. The battery warmer on the unit was an extremely useful feature, as it kept the battery from prematurely fading on cold days, and I greatly appreciated it this winter when it didn't die on me during the middle of a long ride.

I still found myself accidentally taking photos instead of videos sometimes, as the camera would roll over to that mode. It would happen when I either left the menu system after making changes, or when I turned the camera on and the buttons caused things to get out of sequence, and was quite annoying.

Using the HDMI connection, you can stream live or record video to a display (TV) or external capture device. It was nice to be able to watch previously recorded footage on a big-screen TV, seeing things with exceptional clarity, spaciousness and sharpness.

POV Camera Shootout
I am going to do a full-blown and detailed POV camera comparison sometime in the next month or so, but I thought I would give a mini shootout of three cameras, the GoPro HERO2, Contour+ and Drift HD (joined later by the Reply XD). I picked some features and functions I think are important, and gave a general viewpoint on their respective qualities. High marks go to the GoPro HERO2 11MP sensor and mounts, but the competition still has other things they do better. When it comes down to it, it's a matter of personal choice, as they all take great footage, and have different features and functions that set them apart.




Bottom Line
The GoPro HERO2 is an outstanding camera, and the addition of the 11MB sensor and sharper lens, greatly increases the clarity, vividness, and the colors that are captured. The colors were warm and vibrant, although the reds and yellows were overtly so. The new low light sensitivity extends the metering range, and when combined with its excellent bright light characteristics, it makes for a synergistic package, although it still doesn't have the capabilities for exposure or contrast adjustments. The upgraded UI is intuitive, and it's much easier to perform configuration settings and modal changes, with the highlight being the main mode screen, which offers a plethora of information, including resolution, FOV, and battery and SD resource constraints. The menu is still cumbersome and too linear, albeit it's at least effective. Other additions, such as the battery warmer and HDMI output supplements its functionality. The form factor of the camera is somewhat lackluster, as the buttons are stiff, and as it's tough to know what the camera is capturing, and the operational status, such as power and recording, can be difficult to ascertain, albeit the new louder mode beeps and additional LEDs help greatly with the latter.

It has a nice suite of video resolution settings, including 1080p 30fps, 960p 48 fps or 30 fps, 720p 30 fps or 60 fps, and SD at 120 fps or 60 fps. The 1080p mode now has three FOV's, 170º, 127º and 90º, while the 960p, 720p and SD all stay with 170º. The highlight for me was the new 960p 48fps, and it was my favorite resolution mode, offering great coverage of the trail and smooth transitions and flow with the slow mode setting.

The photo section got a slight revamp, and can do single, 10 photo burst, time-lapse (pictures every 1/2 to 60 seconds), and self-timer pictures, in resolutions of 11MP, 8MP and 5 MP, and FOVs of 170º and 127º. The action specific modes of a time-lapse picture every 1/2 second, and 10 photo burst in 1 second should provide some interesting footage.

The mounting system is excellent, and the vast assortment of mounts and connectors, allows attachment and placement in almost in desired location. The quick-release buckle is easy to use and works universally within their system, although the interface between it and the slider mount can be sloppy without some minor modifications. The smooth arm pivots can slip on each other unless some force is applied to the thumb screws, usually using a screw driver, otherwise things move around too easily. The camera and housing are tubby, and sit up perched high on your head and bike, and tend to get knocked out of position, especially if riding in the woods.

Final Thoughts
GoPro has a superb new camera on their hands with the HERO2, and their excellent mounting system, is joined by an upgraded UI, and better form factor additions with louder beeps and recording LEDs, and a battery warmer and HDMI output, and a 960p 48fps, and finally two quick action photo modes. The highlight of the camera is the 11MP sensor, sharper lens and faster processor who work in synergy to create stunning footage.
