He is using the second one in my list: Twenty20 VHoldR CountorHD
Yup, that's a 320X240 video. For posting to the web, that's OK ... but bigger is better.
Why?
Well, because you can go from a big picture to a small one and retain quality. But, you can't go from a small picture to a big one and keep quality.
You have probably seen this type of phenomonon with pictures on your computer. If you have a small lo-res picture and you try to make it bigger, it gets blurry and loses quality. But, if you have a large hi-res picture and shrink it, the quality is preserved.
Golden rule: you can make a big image/video smaller ... but you can't make a small image/video bigger
So, with standard video, the magic numbers for resolution are 720x480. That's the minimum for what I will call broadcast quality video. Below those resolutions, you will have problems trying to play back on television sets and with DVDs ... and with editing in general. Almost all the video editing programs I know of are set-up to use 720x480 as optimum settings.
If you can't get 720x480, the next best setting is 640x480 ... and then 512x384 ... and then 320x240.
Trust me on this. If your videos are good, people will ask for copies. The conversation usually goes like this:
"hey, that was a great video, can I have a copy"
"sure, I can give you a downloadable file (at 320x240) that you can play on your computer"
"well, I wanted a DVD I could play in my DVD player"
"I can do that, but it's going to be like watching the video from the bottom of a swimming pool."Higher resolution is better ...
I shoot everything at 720x480 ... and then compress my videos to smaller size for posting on the Internet. That way I can make DVDs, downloadable files, or streaming flash videos ... all with good quality.
The lowest resolution I can reasonably use is 512x384 ... and that is pushing it.
So, if you plan to spend $179 or more, that's why I feel the GoPro line is better than most of the others ... you get substantially higher resolution.
Here's RAW 512x384 from a GoPro ... note the black border around the picture ... that's the delta from true NTSC at 720x480. The file is 229MB (huge), so "Right-click" on the link below and choose "Save Target As...". It will take about 15 min to download, but you'll be able to see the size quality that comes out of the camera.

http://www.magicratvideos.com/Temp/OneLap/OneLap.wmvBe sure to stretch the videos. Make them bigger and smaller and see what that does to the quality. Then try that with the 320x240 video from the other post. Pay attention to the size of the windows when the file is open.
