    Pues mirando por internet he encontrado un artículo de como mejorar el funcionamieto de esta cámara. Esto nos puede venir bien para los que ya la poseemos o para aquellos que se hayan animado a comprarla.

    El problema principal de esta cámara es que no lleva estabilizador de imágen. También que recoge mucho ruido al grabar. Básicamente este problema viene por el objetivo y la lente que lleva de fábrica.

    Modifying the ATC-2000 camera

    Oh yeah. I'm never content with leaving well enough alone. Be forewarned that if you are afraid of voiding warranties then these modifications are not for you. My goal here is to modify the ATC2K camera to have better audio and replace the front of the camera with a wide-angle lens.

    Fixing the audio

    The main reason that the audio sounds so bad is because Oregon Scientific went to great lengths to make the ATC2K waterproof. The easiest way to get better audio is to remove the rubber membrane that covers the microphone. To do this you need to remove the two triangle-head screws holding the bottom plate on the camera. I've found the easiest way to do this is by using the appropriate sized Allen wrench that will fit tightly in the triangle head and contact the three sides. Once you've removed the two screws you can pull off the plate. With the plate removed you'll see the black rubber that covers the microphone. For better audio just remove that rubber. You can screw the plate back on or leave it off. If you leave it off you'll get better audio. For this mod I left it alone. eventually I will remove the internal microphone and replace it with a jack. Then I can use any mic I want.

    Fixing the lens

    The ATC2K is just screaming out for a wide-angle lens. Most of the time you'll have it strapped close on your handlebars, or down low on the frame. Not having a view screen also makes framing your shots require some guesswork. With a wide angle lens you can catch more video and be closer to the action.

    To make this modification I started by finding a wide angle lens I thought would fit the front of the ATC2K. For about $40 I found a camcorder .5X wide angle conversion lens that came with four different adapters. It is the PlatinumPlus by Sunpak. I chose this lens not only because of the many adapters that came with it, but because it is a wide-angle and UV filter combo lens. This means that the video color and contrast become more vibrant on the ATC-2K.

    First thing I did was to pull the camera completely apart. By the battery compartment there are two more of the triangle head screws. Once you pull the screws out the inside of the camera slides right out. Before I did anything else I held the wide angle lens in front of the camera to make sure I would get the desired results. Oh yeah, awesome stuff here.

    Pulling off the front of the camera is a bit tricky and here is where you'll really render your ATC-2000 as un-returnable. Start by prying the rubber back some to reveal the three Phillips head screws holding the lens protector glass. After you pull out those screws you have to squeeze the retaining plate, glass, and rubber o-ring through the front hole. Now comes the hard part. You'll need to pull the rubber off the front and it is glued on. I found the best way was to use a flat screwdriver and slowly pry around the housing to break the seal.

    Once the rubber has been pulled from the front of the ATC-2000 I found that the 30.5mm adapter ring from my wide angle lens package fit perfect around the front of the camera. By perfect, I mean it is so tight that I had to smack it on the table and beat it with a mallet to get it on. I feel very comfortable that it will not come off. I replaced the original o-ring so that when the wide angle lens is screwed onto the ATC-2000 it seals up against it.

    Putting it back together

    I screwed the insides back into the housing and ran some tests and the camera is much better. The viewing angle is much better and the audio is at least usable now. On our next group ride I'll be shooting with four ATC-2000s simultaneously with one of them being the new wide angle monster.

    Getting better quality through post-processing

    There is not much you can do with the ATC2000 to improve its quality while recording because it is all set up internally. The biggest image problem with this camera is the contrast. This is further compounded by the highly-compressed recording format. To acheive a reasonable level of quality on the finished videos I use Canopus Edius to process the video file after I've edited the clips together. You can download a free 30-day trial if you want to try it yourself. I start by deinterlacing the footage which can get rid of most of the recorded video warble. Then I typically decrease the contrast and increase the brightness some. Finally, I add a small amount of the sharpness filter. The end result looks more like old film than crappy video footage.
