Cinelerra is very powerful. If you are prepared to spend a couple of hours on this web site: http://g-raffa.eu/Cinelerra/HOWTO/ (also known as Cinelerra for Grandma,) you will be rewarded by a very productive experience in Cinelerra. There are also many tutorials on Youtube. I was particularly delighted by being able to create "the Ken Burns Effect" on my first try.
