extreme sports action video camera image
WP Skatebo
Most people still recommend the Sony vx2100 and vx2000, I was planning on using a vx21 Because Baker skateboards use it still, im just wondering how Standard could be better than Hd so i can back up If someone tells me hd is better.
Answer
quality is more than pixel deep. all consumer HD camcorders use extreme compression, like 100:1 or more. when you throw out that many bytes, something has to give. like entire frames of video. most HD cameras take only 1 actual picture for every 8 frames, on playback the missing frames are artificially reconstructed by interpolation. that process works ok if there is no motion, but for action sports it sucks.
miniDV cameras employ a 6:1 compression scheme. that small compression allows it to keep all the frames, so it can handle motion very well. having lots of pixels is not an advantage if the pixels are all blurry because of action.

Is SanDisk Extreme III 2GB SD Card Memory Card a lot better then the normal SanDisk 2GB SD ?

I'm thinking of which one to buy for my camera, but I don't know which one to get. Money doesn't really matter, as I can get the Normal one for £8 and the Extreme for £12
Is the extreme much better then the normal one, or just slightly better?
Answer
Only if you are shooting video on a P&S camera or if you are shooting "shootgun" method action shots. Most sports and action photographers shoot at the peak of action, so shooting at high fps speeds (the reason for highspeed cards) is not necessary.
You can test for yourself .. buy one of each and then do your test. I have both in my cache of memory cards, but have never had to wait for my card to "catch up" and I always shoot RAW + JPEG Basic.
If you decide to spend the extra £4, check before you buy and make sure your camera supports highspeed cards. Many of the older DSLR's (three or four years old) do not support speeds over about 40x
