SnagIt isn't really a video editor. You can record video, but there's very little else you can do with video in the SnagIt application.
Camtasia is a brilliant video editor, and is also provided by TechSmith. If you were asking how to do this in Camtasia, I'd tell you to create a logo track and have it be equal to the length of the video. You'd also be able to decide where to position it on the screen.
But this is beyond SnagIt's capabilities. (PLEASE, anyone, correct me if I'm wrong here.)
Good news, importing a SnagIt created video into Camtasia takes about zero effort. Super easy and I find Camtasia to be fairly easy to use as well. The tutorials for video editing in Camtasia are fantastic, so take the time to go through them and save yourself headaches later.
It's a free program that you can use to add your logo to the screen while recording. The developer quit selling it due to the fact that he had a lot of problems with anti virus programs detecting it as a virus.
I can confirm that,I have to provide an exclusion in my anti virus software or it gets quarantined as soon as I try to run it.

Just a neat way to display an image on your desktop. I left all the setting windows open so you could see them.Normally you minimize them to the taskbar.The image stays on top of everything.
You can also click through the image with your mouse.But that must be enabled.
