After getting on so well with MPEG Streamclip which is a free application that will convert video for you from one format to another or you can use it to make the file size smaller prior to upload, or you can use to download clips from places like YouTube. It is really a very capable application. I have only just managed to scratch the surface with it today.
But the secret is out and I have made a Screencast showing you some of the settings and the successes I had while learning what it can do for my work flow. Matthew of the StealthMac Podcast suggested that I use MPEG StreamClip with the movies produced by ScreenFlow before putting them into FinalCut Express. I found that a good idea. It means that there is less rendering to do once you have the clips on the time line.
I did try to convert a DVD to .h364 but that was not a success. the finished file was bigger and also the sound was way out of sync. Have a look at the video below to see what I have been doing today and you will see how you can make use of the free application too.
