I am contemplating buying a mountable sports cam, and was wondering what the minimum requrements are in terms of resolution, frame rate, memory card size, battery life, etc.
I don't know that I am going to be any good at it, or anybody will want to watch them, so I am looking at what kind of bangs I can get for few bucks.
The Kaiser Baas Sports Cam (here) has had reasonable reviews for what it does, but they say the colour saturation is a bit dodgy. I have seen videos using this which look ok to me, but the GoPro/Contour videos do look better, but are $200-300 more.
For simply filming riding up or down a hill, do I need anything more?
Maybe you will be interested see this comparison video
My comment after see that video
Kaiser Baas have a lot of rolling shutter or "Jello effect" which can be very annoying if you recording your cycling because you will move fast and captured video will not clear and may give you headache.
In my opinion GoPro or Contour will be a worth investment because you will get what you pay, you will get one of the best sport cam, and you can sell it quite easily with reasonable price if you don't like it.
Sometimes it is better to spent more rather than regret buy something cheaper and ended buying the more expensive one.
ET take a look here http://www.bicycles.net.au/2012/02/video-cameras-cyclists-use/ There is a $47 option which the reviewer reckons gives the greatest result for the lowest price. My problem with most cycling videos (mine included) is that they are like watching grass grow after about 30 seconds. I've recently seen some great alternative video mountings which provide some visual perspective and lack of sea-sickness-inducing motion that you get with standard handlebar or helmet mounts. Low down on the seat stay, facing backwards gives a sense of speed, especially if you can capture part of the rear wheel. Low down on the front fork facing forwards (for the same reasons), somehow mounting on the top tube just behind the stem so you dont get side to side movement from the handlebars, but get to see the bars are all good options.
Some nice on-bike mounting options in this video around the 1 min and 1 min 30 sec times. A few look to be mounts attached to the rear axle, but others I have no idea how they mount the camera and keep it from shaking like crazy.
