Hi Bakari,
as far as I know, the new version of TeachMac dropped the limitiation of a fixed window size. But there is always the concern of Video size: the larger the capture window, the bigger the resulting video. When I first started working on tutorials, I also felt that it would be best to capture the whole screen to get everything. But now I find that in most cases 720x480 is quite sufficient - and even preferable since it keeps the focus on what's important. I sometimes start a new capture if I want to show a different part of the screen and then piece the parts together in iMovie.
Hope this helps,




I'm working on my first module and I'm using one of the video tutorials as a guide. In the guide it says the size of the capture window using iShowU should be 720x480. But that size seems rather small for trying to show all the important windows or panes of an application you're tyring to discribe. Can the screen capture be a little larger?
