I just had a play... I placed a rather nice, chirpy estuary bird, wallowing in mud MP4 clip taken with a Panasonic camera and the MP4 version of my sunset movie into iMovie together.

I can cut and clip, stretch and squash, insert *new* transitions, titles and any other effects into the movie.  What I can NOT do is EDIT any of the pre-existing titles, framing, fades or effects in my Sunset Movie, yes, I can edit anew but not adjust any previously created effects, that is the whole point of what I was trying to say, but not explaining it very well.

Once an iMovie (or any other movie creation software) has compiled the component parts of the work, the transitions, titles and effects (which can take HOURS to get right) are no longer directly editable.  They can be cut out then redone, split, chopped up or re-edited perhaps but effectively once compiled, they are locked, a wrongly spelt name in the credits and the whole compiled movie is junk.  Most 'serious' software (Adobe Premier?) allows the original document to be saved, in most cases incrementally (to allow two or more options to be tried? so the editor can revert to an earlier point) and re-edit, PRIOR to compilation, compilation is far more than just saving the movie, it locks all the clips, images, sounds and effects and converts the whole assembly to one homogenous file.  Back in the early 2000's I used Final Cut Pro on my fairly competent dual processor, liquid cooled, Power Mac and it used to need to spend all night compiling a modest 15 minute movie of the kids taken on a Sony tape cassette video camera.  It was a non trivial process, far removed from simply saving the file.

I can still access the uncompiled version of my Oakdale Sunset movie, but only the version immediately prior to compilation.  If I wanted to experiment with the layout I would have to start over from scratch, I can't save what I have, then edit the file a different way.  This is one of the reasons I try to stay as far from video as possible because of the complications of editing it.  It's probably why the software is so expensive because not too may people want or need to jump through these hoops, so the cost divided by the projected number of users tends to make it expensive; and it's complex, sophisticated software too.
