| After youíve captured your video, the next step is to trim away all those sections not wanted in the final project. One software that I use for this task is ScreenFlow by Telestream Inc. Itís easy to use and therefore you get the job done quickly. ScreenFlow is a screencasting and screen recording software.|
Letís walk through the process of trimming a few good clips from a playback recording of an iPad storybook app. When I used the Reflector software to record the book app, I recorded it from start to finish. Now that I have a better idea of what I want to include in my book trailer, I can trim away the unwanted footage.
Because the video will be used in a trailer for the book app, another decision to make at this stage is the size of the app in the book trailer window. I also want to use a png overlay of an iPad, which will take up some space in the trailer window. So I tested the png in the window and decided that I needed the playback of the app to be 680 x 510 pixels.
