Try a trial version of Camtasia - it might suit your needs better

I don't want Camtasia.  If I wanted it, I would have chosen it.  I wanted Snag-It.  That's like saying, "If you don't like the steak, try the potatoes."

I'm sorry, but I thought you said you were testing things.  In fact, yes, you did. That's why I said "try it". I think what I was actually saying was, "If you don't liked the minced beef, try a steak."

The video capability in SnagIt is crude.  Personally I don't see why it's even in the product given that it is so often, as in your case, called out as being inadequate, and when there is a better option in the same stable.  We could equally say that Camtasia is crap at taking screenshots.  But there you go.  It's in there, warts and all.  

The only thing I ever use it for is creating gifs to illustrate an issue. But that's only because I'm too lazy to fire up FlashBack to do it when SnagIt can at least make a decent job of doing that.

But if you want to moan about the one product you've tried and complain when someone points out an alternative that might suit your needs better, please go right ahead.
