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

Hi Max,
Cheers for the quick response.
tbh, pix_film is the reason I know the pixel dimensions already:)
Would you mind explaining in a little more detail - which objects and how?
I am unclear on the relationship, say, between [rectangle 3 2] and 320x240 pixels, and again how that corresponds to [translate] and the numbers I am putting in the inlets 2 and 3 of translate. 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?
Kind regards,
Jb

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.

Hey again,
So,
I have my 3 avi's with 3 seperate [gemheads] which I can now move around the [gemwin]. Cool.
Could someone enlighten me towards the relationships between [translate] and [rectangle] please?
I would like to keep the original aspect ratios for the 3 avi's. 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.
Apologies in advance if I have missed something in the helpfiles or various tutorials but I can't seem to find the info I'm looking for.
Best wishes,
