Time lapse editing

Hi Guys,

I've just bought a go pro style action cam (mivi HD10) and I'm taking my first steps in video editing.

I've got a few questions about making time-lapse sequences.

I've been using quicktime pro to assemble the sequences because iMovie doesn't seem to handle it very well (it's very jumpy and I can't seem to get it to go below 4ms per frame).

I've just done a few adjustments in aperture to all the photos to get the style and cropping right, this is obviously taking quite a while. Is it best to edit the frames in a photo editor like this and then stitch them together, or would I be better off doing all the editing in iMovie? Presumably aperture will do a better job of editing each frame?

Another question is a bit more general, but I was wondering if it's worth upgrading to any other video editing software compared to iMovie at the moment, or if iMovie will be fine until (if) I get more serious and go for something like FCP or adobe premiere? If I did it would have to be something fairly low cost.

 

I've got another question which I'd love someone to point me in the right direction about.

The camera has a 170 degree lens, so the pictures come out with a fish eye type distortion.

What is the best way to correct this? Is there a good plugin for aperture or should I be using some other software? Also when I need to correct this distortion in a video what software can I use for that?
