What is the difference between 720p and VGA?

Q. I have a Kodak Mini HD Camera/Camcorder. I can switch my camcorder between 720p resolution and VGA. My question is, which one is better? Also what is the difference between the two? I have never really heard of VGA until I got this camera.
I have never really researched any of this until today and just could not find something that explained it well enough for me. Thanks for any answers

A. VGA refers to the resolution 640x480, also know as 480p in video camcorder terms.
720p is of course better quality with a resolution of 1280x720, about 3 times the pixels of 480p and therefore takes about 3 times as much memory. Also, the shape of the final video frame will be slightly different, with 720p being a longer and thinner frame (higher width ratio to height).
Altogether, 720p is a higher quality, or generally 'better', and classed as HD, but will use up a lot more memory than VGA.


What is the best quality camcorder for youtube?
Q. I am trying to buy a good quality camcorder for youtube with 720p. I know that the flip is an ok camera but I heard it is hard to control and does not have good image stabilization. What do you use and can you show me an example?

A. I would suggest Sanyo VPC-CG10 HD Flash Memory Camcorder
- Capture HD digital video (720p, 30fps) and up to 10-megapixel still photos
- 5x optical zoom; 3-inch widescreen LCD
- Face Chaser technology (can detect up to 12 faces for photos and videos)
- Built-in still photo flash; High-Speed Sequential Shooting (7fps)
- Capture video and stills to SD/SDHC memory cards
