Aspect ratio

[Eric Murty]

Ok I got the math of it now. I saw this site today which is presenting quicktime video which is not your usual size and the video does not look distorted. Maybe someone can shed some light as to why.
The size seems to be 600 x 416. Now I presume it should be 600 x 450 in order to keep the aspect ratio correct.

I just downloaded the file and the size is 600 x 400 which is not keeping to the set aspect ratio. if it was it should be 600 x 450.
So can anyone explain why they are not having any distortion?

Thanks for all the help on here.

As far as I’m concerned all those clips are distorted, squashed, squished or whatever you want to call it. Nobody has faces that fat where I come from!. (I’ll ignore the rest of the terrible encoding ‘mistakes’ for now….)

That said, you can make a clip any size/shape you want, from perfectly square to wildly rectangle without distortion. You do this simply by cropping out that desired shape from the original frame.

So to clear me up is DVD 720 x 480 16:9 ratio or 1:5 ?

[Daniel Low]

Neither – DVD 720×480 is 4:3, using non-square pixels, if were using square pixels it would be 1.5:1
