look on c.net reviews and they tell you everything you need to know about camcorders also they give a review and tell you the pro's and con's as well as the price

how come the 0.7 mp camera of the ipod touch 4g can capture 720p video?
Antar O
but does having more mp make the video quality better? or it doesn't matter?
Answer
Interpolation. The output does not really have the 1280x720 resolution, it is just in the 720p format.
If you look at the detailed camcorder reviews at e.g. camcorderinfo.com you will find that this is nothing new. Most consumer "HD" camcorders, when resolution is actually measured (by pointing the camera at a test chart and seeing how many lines can be resolved in the resulting recording), do not come close to the possible resolution of the format.
Edit - added: Some misinformation posted here by others needs correcting.
1. "720p" refers to 1280x720, not 1024x768. 1280x720 = 921,600 pixels. 1024x768 is called "XGA", not "720p".
2. 921,600 pixels is 0.9 megapixels. The "mega = 1,048,576" conversion is ONLY properly used for RAM. For example, a "100 megabit" Ethernet connection runs at 100,000,000 bits/second. A "500 GB" hard drive has 500,000,000,000 bytes. Similarly a "1 megapixel" image has 1,000,000 pixels.
3. In video formats expressed as e.g. 720p, you do not take anything away for "invisible sync info." You don't do even do that for SD when it's quoted as "480i". All 480 scan lines are visible picture info. Yes, there is invisible sync info in NTSC, PAL, etc., formatted video, but for ex. in NTSC this is how you get from 480 to 525 scan lines; the sync info is in the extra 45 scan lines. Similarly in HD formats, "720p" means 720 *visible* pixels on the vertical dimention, , just as there are 768 visible pixels vertically in XGA. Now, sync info must of course be sent to the display, and this does take time - but there are still 720 visible lines. So there is no "7 percent less" to allow for sync info.
Edit2 - added: I have the answer!
The sensor actually is 1280x720 pixels, so it can create 720p video, no problem. That is a 16:9 format.
But still pictures... most still camera take 4:3 pictures, and the iPod's camera does the same. A 4:3 picture with 720 pixels vertically is 960x720. That's 691,200 pixels, or 0.7 megapixels.
So it doesn't have a 0.7 mP sensor at all. They just only use 0.7 mP of it for still pictures.
