its strange how we look at things
comparing the video quality of the x170 camera to the samples you've posted, for me the x170 images seem smoother and more realisitic. my perception of the hero images was that it was jerky. now that always a tough one to resolve. I wouldn't expect to get those sort of problems on a PC... its the sort of issue Ive seen before when looking at stuff produced for the US/NTSC market place in PAL, or vice versa.
I'm not over fussed about the sound of the bike, what I am fussed about id the image quality. some of the samples on the GoPro site look fine, which makes me wonder if mebbe its an artifcat of the camera you have or the settings you used.
But i question how much reliance you can put on the manufacturers images. right now Im looking at two video's posted by users as opposed to makers.
Im looking at doing a big trip next year, and fancy the idea of some videos and or stills whilst on the road. I've toyed the idea of getting one of the Sanyo 'phase' style Xacti cameras. i've looked at one of the bike powered 'bullet' cameras from the likes of 4Kam
, which look to give excellent results.
right now I'm tempted by the X170, the Gopro at present is ruled out because of the cost, whether its the importer or the manufacturer but we, in the UK seem to be on the age old scam of parity between sterling and the dollar, so the UK list price for the new HD camera is £300 as opposed to the £180 odd the exchange rate would suggest.
