>>>I purchased SnagIt a few months ago and I have done some screen captures.

>>>Now I am learning how to do video captures. Basically I want to create some small (no more than 10 min) training videos of some features of my app. The first thing that I noticed is that SnagIt creates the video in .MP4 format (Because when I hover over the date-file created in some temp folder the extension is .mp4). If I then, later, send such an .mp4 file to a customer, how easy or difficult will it be for a Windows user to view this? Should I change (if it is possible) the format that SnagIt uses when creating video captures?

>>For video you should rather use Camtasia, which is also made by Techsmith. It has a lot of extra features for video capturing.

>But then I have to buy another product. Unless I see some big advantages of Camtasia vs SnagIt, why bother.

You wanted features which don't come with Snagit, so I pointed you to one that probably have them. I suggest that you try Camtasia for free, and then make your own conclusions.
