The HVX200 represents a new direction in HD cameras, moving away from both the large tape format and from Sony’s smaller miniDV HDV tape format. The use of two P2 cards (which are a RAID system of SD cards) means that the HD system is tapeless and this solves some problems, but also adds new ones to the mix. There are plenty of reviews of this camera and P2, but I’ll focus on how it works for underwater shooters.
The main problem with the new P2 format is the lack of space on the cards for recording time. Topside you can plug straight into a hard drive or you can hot swap the cards for endless recording, but underwater tis not so simple. The 2x8GB cards give you 17 minutes of recording time at 1080/25p, 33 minutes at 720/25PN, or much longer if you want to shoot standard definition. The camera also has a miniDV tape so you can at least still record SD if you manage to fill the cards. Bigger P2 cards are on the way 16GB and even 32GB have been mentioned.
The limited recording time is seen as a major hurdle, but to be honest I have very rarely filled the cards. I do tend to shoot at 720 most of the time, partly because of the longer record time but also to take advantage of the variable frame rates only possible at 720.
A very cool feature of the camera is PRE-RECORD which caches what the camera is seeing and allows you to record from before you actually pressed the record button. This is a major space saver on the cards because rather that shooting 5 minutes of rubbish footage waiting for a frogfish to yawn or a shrimp to come out of its hole, you just point the camera and wait, when the action happens, you press record and you catch the action you would have missed with any other camera.
In terms of workflow, I have come up with a system that works great on a liveaboard which is pretty much all I have done (working on NAI’A) and it goes like this…. Get out of the water, dunk the camera in a rinse tank, take the back off the housing, plug in a laptop connected to a 2TB RAID drive and another hard drive to make two copies of the data, go and eat, come back 30 minutes later, clear the cards, put the back on and go and do it all again. Very simple really, but I could see it being a problem on small open boats without AC power. For 2-tank day trippers, a laptop with a powered external hard drive like the LaCie ‘Rugged’ works for one dump of the cards between dives, maybe even two or three dumps, depending on your battery life. You just need to work out a system that suits the conditions.
The Gates housing is brilliant. Its one drawback is its size and weight. For travelling it is a beast, my Pelican case with housing, lights, monitor, tripod and all the bits weighs 32kg. Airlines love that. Getting it in and out of the water can be tricky too, especially if it is rough and you don’t have a crew of strong Fijians to help you out. Once underwater, though, all is forgiven. The housing is well balanced, and with the buoyancy aids from Gates you can make the rig neutral or slightly negative. Once you get used to the controls, they are easy to use and all line up beautifully. Some controls are optional, but get them all. There are loads of controls on the camera, and six “scene files†which are presets that you can setup topside for different underwater shooting conditions. The Fathoms SW44 superwide angle lens is awesome, costs an arm and a leg, and I think is crucial to the system. It has great zoom-through capabilities so is a good all-rounder. At full wide it is really beautiful, these HD cameras need a lot of light and this port lets in a much a possible. The flat port for macro shooting works well because Gates have added two flip filters which you can fill with one or two diopters, or a diopter and a red filter. Only the red filter can be used with the Fathoms lens due to space and optics.
Overall the learning curve is steep. It took me a while to figure out the basic settings and I still don’t have it right yet (I am not totally happy with the noise in the blues and blacks) but it is a great system and I am pretty happy with the results I have got so far. I have a demo reel filmed with this system at www.underseaproductions.com/stock_footage.html if you want to see what this rig can do.
Happy shooting and go Gates.
