webcam with a good refresh rate?

Hello,

I recently got a logitech quickcam communicate stx webcam from radioshack.  The quality of the picture looked good until any movement happened.  It has a horrible refresh rate!  I'm going to return it today and was wondering what is a good quality webcam that will give smooth videos?  On this one, when I talked you couldn't even see my lips speaking the words, it was that bad.  If I dropped the quality down to 320x280 (instead of 640x480) it was a little better but still bad.  The videos on youtube don't look this bad.. I'm assuming many of them use webcams.  So my question is: what decently priced webcams out there will give a really good refresh rate, and a smooth video?

thanks

I have a Microsoft LifeCam VX-3000.  It does up to 30 frames a second (Television quality) and I got mine for 24 dollars including shipping on E-Bay.  They sell new for around 30 dollars.

is that 30fps on 640x480 resolution?  the other cam i had did 30fps on 320x280 but it still seemed kind of jumpy..

my main goal is to just get a smooth video, even if it's not a web cam.  I'm not going to be doing video conferencing so bandwidth is not an issue.  I'm just looking for something cheap that will make a really smooth video even if there's a lot of movement.. i don't want it to blur like the other one did.  would you say the vx-3000 is good in that case?

Most webcams these days use CMOS sensors for acquiring images. The better webcams will use a CCD imager which increases the quality of the images considerably as they are more light sensitive. I've had a preference for the phillips brand of webcam as they seem to be of better quality ,imagewise, than most.

I use mine for video conferencing on a dialup connection and it's seamless.  I would think that it will work fine for your situation.

That's not to say that there aren't other good cams out there, I just have experience with this one...and I can't tell you the exact frame rate at 640x480....but that's the resolution I use.

does the video seem jerky with that one at all?  What if you move really quick, does the picture stay clear or get blurry?  Those are the two things I'm trying to overcome... to be honest i don't really care about picture quality as much as good motion

In the end you will probably get what you pay for. A cheap cmos webcam will not have the quality or the smoothness you desire. That only comes with a ccd webcam of which some have frame rates of 90fps.

It isn't jerky at all...in fact, this model has a feature that will actually follow my face within a certain range (within the frame).  I've been very happy with it.  I get the occasional hiccup where it stutters (once every 20 minutes or so), but I am positive that this is related to my dialup connection.  Keep in mind that I have a 3.0 Ghz Processor and 2GB of RAM.  Those things will make a difference too.

Sparkmaker isn't wrong.  A more expensive webcam will almost certainly give you better quality results.  I was trying to give you the benefit of my experience with what I consider to be a relatively cheap webcam.  I've been pleasantly surprised.
