Quicktime PRO Edits videos in seconds! How??

It is a very useful feature, combine with frame by frame skipping, it's totally invaluable.

The trimming feature is simply like cropping a photo. Select the part you want, copy it, make a new file, save it. It will save it the original encoding (audio, video, subtitles, etc.).

iMovie always re-encodes it. Ie: small, medium, large etc. So there is the overhead of converting the video.

Yes, it is not re-encoding it.

Is it actually trimming the video file, or just placing a new start-time and end-time marker in the video file? Meaning, if you have a 1 hour 600 mb movie and crop it down to 1 minute, will it now be a 60 mb file, or still a 600 mb file?

It works like select/copy does in preview. Simply place the braces around the part you want (or you can press command-a for select all), then make a new movie (command-n) then paste. The pointer is where the pasted section will go, so you can paste the two movie sections in any order.

I guess it will be in proportion to the length of the cut section (not precisely, but very close). So a cutting 1 min out of a 100 min movie (1000 mb) will make it a 10 meg movie.

The result video is smaller in size ..

in my case i trimmed a music video (74mb / 00:4:10 ) and what i got is (63.6mb / 00:3:38 ) ..

what kinda excites me is that the result video is ".mov" the original is ".avi" ..does it really matter ??

.avi is simply a container file for movies, like .mov is for QT and .mkv is for open source.

I used to have a problem with .mkv movies playing in VLC, so all i do now is opening it QT Pro, when save it when it has read the entire movie (QT does this to .kv movies for some reason). It saves it as .mov and it plays fine everywhere.

If you want to watch a .mov file, you'd probably need QuickTime to be installed. No problem on Macs, but not every Windows machine might have it.
