I am creating a video explanation of Seismic Waves for my Physics Class. I am using Camtasia Studio 7 to "stick" everything I do in AFX.
I have some kind of "main frame" where I created a nice effect running in the right part of the screen, in the left side I left enough space to present the things that the video will go through. I want each of my four videos with seismic waves to appear there, along with a text, one by one. I want one video to fade in, stay there like 2-3 secounds and then fade out, the next one to fade in, stay 2,3 sec and fade out and so on. (note: It doesn't have to fade actually, but I just gave it as an example). This would be like some kind of preview, and the next things, since I do not handle all the effects yet, I could do in Camtasia.
The biggest problems I encounter are with the video in video thingy, since I don't know how to make the videos to appear and disappear at a certain time, nor the framing and the fading.
