[Max]

dimension x divided by deimension y gives you the aspect ratio. see attached patch:

For example when I increase the 2nd inlet of translate (magnification? sorry I'm not in front of pd atm) my 2nd avi movie moves in a north easterly direction from within the gemwin and I don't understand why?

Assuming that the movie is in square pixels (which is the case if you are using screenshots and webcam movies) this allows you with a couple of objects to automatically scale the rectangle it is textured to to fit the right aspect ratio.

Avi 1 is an odd shape  - w432 h768 - (it's approximately half of my laptop desktop recorded with RecordMyDesktop) and avi 2&3 are recorded off bog-standard camera's, so are 320x240. The larger file is on the left of my gemwindow with the 2 other avi's to the right, one above the other.  I have added the widths of film 1 and film 2 with little borders which gives [dimen 762 768(.  I can move the files around and get an approximate fit moving between each [translate] and [rectangle] but I get the feeling there is a more rigorous approach.
