What does the numbers mean on a video camera? Like "12 x optical zoom"?

Q. Someone please tell me what all the numbers and pixle numbers mean on a video camera.
I need a really good "flip out screen" one.
- I also want it to go up to 1080p, ( i think its 1080 HD) or 720p HD.....
& it needs to zoom without getting blurry, what is that called?
I know if I'm recording a video on my regular camera, and I zoom in, it gets blurry when I zoom in, I need it not too.
Please answer all these questions and reccommend a good HD video flip out screen camera! :) Thanks!

A. There are two types of zoom optical, and digital, the one you want it optical, this is done by adjusting the lens (simply this shows you how it works http://en.wikipedia.org/wiki/File:Zoom_prinzip.gif)

the other is digital zoom, its the same as having a picture on your computer and you zoom into it, all it does it make the pixels larger, thus making the picture/video blurry not good.

many cameras go up to about 30x optical zoom, but can be thousands when using digital zoom, ignore the digital.

Pixels are only for still pictures, not video, its called resolution, its very confusing when makers use this figure.

full HD is 1920 � 1080 multiply the two numbers and you get 2,073,600 (2MP) not as good as they say. for 1280 � 720 its 921,600 less than 1MP. so basically ignore the advertising.

As for a camera Cannot help you have not given a budget, the best thing is to go and have a look at some, decide how much you want to spend (try to keep to it) and get your hand on the cameras, play a little and find one that feels right for you.

Good luck

Can DSLR cameras zoom while taking a video?
Q. So I know that there are quite a few DSLRs out there with filming capabilities but I was wondering... Can you zoom in and zoom out while taking a video? And if it's possible, which DSLRs can do this (name please)?

I've been looking for a DSLR that can take high quality photos as well as take videos. I really want to find a DSLR which can zoom in/zoom out while taking a video simply because my normal digital camera can't (not to mention the horrid sound quality it has). I would truly truly love DSLRs if they can do this.See, I recently went to a concert and could not zoom in to my favourite member of the band with my normal camera :(

A. Zooming is determined by the lens, not the camera. If you have a zoom lens, then yes you can zoom. If you have a prime lens, then no, you cannot zoom.
