I do screen captures of my lectures (using iShowU HD). These are 1280x800. I bring them into iMovie "full size", but when I import the clips into a project they are cropped apparently to 1280x720 (720P I guess). Now I can deal with this by not using the very top and bottom of my computer display, or I can have iShowU HD resize (and letterbox to fit) 720P which results in a loss of sharpness. However what has me baffled is iMovie EXPORT. When I export using QuickTime (necessary for the reduced frame rate I want) it shows the native size to be 960x540, which is half 1080p. This presumably means that if I force 720p it will convert 720p to half-1080p then back to 720p again???? Do I have this right? Is there a better way? Would buying Final Cut Express (or Adobe Premiere Elements) solve the problem? Final Cut Pro is beyond my budget and willingness to learn. I'll be processing about 60-70 hours of video a year and need to do it quickly. I also import some camera video (either the built-in iSight, a Flip or a DSLR) but that's a small part of the mix I am happy with.
