Re: compression and aspect ratio

Hi Andy
First I would just like to thank you for your help and communication...I have been stumped on this for a while and everyone on the forum is super helpful and nice.
I am using AE 5.5 and dont see the button to switch over to see what I would see on DVD in the bottom of the comp window...Is that only in newer versions??
So if I use the 720x480 widescreen comp setting just leave the footage squashed looking??..only asking because of the above reason with AE 5.5..if I dont have a way to monitor what it will look like on DVD... so as long the comp says widescreen 720x480 and I use the amamorphic pixel aspect ratio setting then all my stuff should be widescreen anamorphic?? I have experimented alot and last night I rendered out something from AE at 720x480 and then imported into sorenson squeeze and the video showed up 640x320 and in 4:3 even with selecting the 16:9 hdtv DVD smart template. if it was rendered from a 720x480 widescreen comp seting then why does it show up 4:3 in squeeze...when i change a setting in squeeze to raw(square pixels) it only then goes into 720x480...is it just rule of thumb that as long as i create in the right comp setting then the DVD software settings will just take over and make the final output widescreen or anamorphic? just very confusing and frustrating because I have been looking at it as taking something that is 4:3 and trying to put it in 16:9.
thanks again
