Movie Whirl is simple in it does only rotates in a 90 degree left per double click, making the user have to double click multi times to get your movie the way you want it. We could have advanced this application but the word freeware would have not been part of the product. Even the simplest of applications take time to present and deliver to the public to use.
There currently are a few products on the market that also include features to rotate movies along with many other things. Most of them are not a free tool as Movie Whirl is.
