Simple Web Cam Demos for Mac OS X




Next month I'm going to do a little demo of adding memory for my local computer club. I have some old machines I can use for this, including an old laptop, so I'm all set with that.

But then I realized that we usually have too big a crowd to be scrunched around a table watching this. We do have a large screen TV.. how can I use that?

Well, my first thought was to use a little webcam and multicast it from QuickTime Broadcaster. I could do that and pick up the stream with QuickTime Player.. that works, but there's a delay. I don't want a delay if I'm talking about what I'm doing now.

The Preview window in QuickTime Broadcaster is just what I want - there's no delay - except that it's too small. Even on the large screen, it will just be too small for people to see.

So that won't work.. or will it?

QTB

Actually, yes it will.

I forgot that I can scroll up my screen size just by holding Control and using a two finger scroll on the trackpad. If I position QTB so that the preview window is mid-screen, I can scroll that up to full screen and with the big screen mirroring my display, I have just what I want: full screen video of what I'm doing with no delay.

Simple, low tech (well, moderately low tech) and effective.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

I am a Kerio reseller. Articles here related to Kerio products reflect my honest opinion, but I do have an obvious interest in selling those products also.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
