Hi, i have been making some very basic movie tutorials for youtube using iMovie.
I would now like to improve on them and i was hoping i could get some help here:
01 - what is the best mac software for:
a - recording screencast tutorials (recording your web browser etc)
b - crop a small part of one video and place it on top of another full video (layered videos)
02 - is it possible to zoom in on your video on certain parts and then zoom back out (see 6:29 - http://www.youtube.com/watch?v=xNsGNlDb6xY
03 - what is the best size dimensions for creating and recording video for uploading to HD youtube
Thanks in advance to any help you may be able to give.
