Widescreen renders are Sqashed when played in quicktime
I’m having some issues when rendering widescreen 16×9 (1.2) videos. Whether I render AVI’s or MOV’s from premiere pro CS3 they play squashed in regular players such as quicktime and VLC, but when I import them to an editor like final cut or premiere or after effects, it’s the right aspect ratio. I’ve tried rendering them square pixel but it looks bad and has a green line on the bottom of the video. The regular widescreen looks great! except for the fact players squash it.
Basically, How do I render a 720×480 widescreen video that plays widescreen on regular media players and not squished. I think it has something to do with the pixel aspect ration but I don’t know what setting to choose.
I’m on a PC
using the production premium studio CS3
Premiere pro specifically

The wide screen thingy is a DVD feature. Many standalone DVD players will pick up a “switch” embedded in the Mpeg file and stretch the video on a TV. Other players will have be manually configured.
Computer monitors can only display square pixels. NLE’s can interpret the captured video for editing. -
You should be able to export to Quicktime using 854X480 (square pixels) without seeing any problems. Is that what you tried?

You know what, I didn’t and now that you suggest that, it makes perfect sense. I was trying to do square pixel at 720×480 and getting interesting results. Thanks Steven.
From what I gather, what happens when you don’t do it as square pixel it makes it anamorphic? ie. required the pixel aspect ration to be stretched. Hence my Quicktime plays it squashed and VLC requires me to switch it to 16×9 mode to correct.

it works perfectly 854×480 square pixel, as per your suggestion by the way.

DV in 4:3 aspect ratio is .9 PAR (slightly skinnier than they are tall) and 16:9 DV is 1.2 PAR (a bit fatter than their height)…both have a resolution of 720×480 NTSC (or 720×576 PAL)…
Neither Windows Media Player or QuickTime Player seem to do well with non-square pixels. No really legitimate excuse for it at this point…
