This is a very important feature that I find necessary all the time when working with a different software package on the mac. It would be a very valuable option for Screen Monkey to have in even making small sizing adjustments....ie...getting rid of a any visible unwanted noise (timecode track) at the top of a video.
To be able to size each and every video clip...either a standard ratio adjustment (4:3, 1.333 or 16:9, 1.777) and also perform a custom adjustment plus or minus the horizontal and vertical sizing. And being able to zoom in or out on the clip after the correct ratio is determined. This allows you to go full screen with the correct aspect ratio. Also, the ability to crop & pan on the clip would be useful.
A scaler option would be very helpful. However, it may require a Preview monitor to see your adjustments in real time.
Could also normalize (plus or minus) audio tracks in the same panel.
