Resizing a movie?

Depending on what you mean by 'Movie', Handbrake can do that. Check the Picture options for the resizing...

i think in iMovie/QT if you Export/Share you get to choose from "mobile phone", "email" etc.. and they have pre-determined movie sizes, one of which may be what you are looking for.

 

go to Export in quicktime and click on Options after selecting what you want to export as (Divx, QT mov, etc). Here you can go up to "Size" under the video settings and set your resolution.

AVI is just an extension and not a format...so you should find out which format you want.

 

here is the long winded way but it shoud work...
export your movie from imovie or whatever so it is on the desktop,
open in QT pro

Export from QT pro, movie to QT movie, & click on 'options'

on the video tab, set compression to None
and size to 'Custom' & Enter 128 x 128 in the boxes.
the likelihood is your movies are not square so select 'Crop' in 'preserve aspect ratio'
OK

When that box has closed in movie settings select OK
then back to the Save box & save as whatever128.mov ( dont go over the original)

open whatever128.mov in QT Pro & now export again as an AVI.
