Widescreen Confusion
I am mixing graphics with video that will be displayed on a Widesreen Plasma TV. The problem is all the footage Im working with is 4:3 (720×480). I dont mind scaling the footage to fit so there are no black bars, but Im SO confused with all the posts on here that talk about square pixels, 720×480 widescreen, 864×705. Any clarification would be GREAT!
What do I need to do in FCP settings wise?
Thanks.

What you need to do is change the aspect ratio from 4:3 to 16:9, now the squareness has to do with how square the pixels are, on a wide screen they are more rectangular. For your purposes you need to make sure that your sequences are 16:9 anamorphic.

Hi
Does anyone know a good site with info expaining Aspect Ratio? -
all aspect ratio is saying is that in the case of 16:9 there are 16 pixels accross for every 9 down…

Not in SD. Both 4X3 & 16X9 have exactly the same pixel dimensions. The difference for SD is the shape of the pixels, themselves. Uncompressed SD pixels are rectangular, uncompressed HD pixels are square (in an effort to further confuse us, some compressed HD codecs use rectangular pixels). For NTSC, SD is 720X486, regardless of the aspect ratio. For 4X3, those pixels are taller than they are wide, for 16X9, they’re wider than they are tall. But both are still 720X486 (which would give you an aspect ratio of 40X27 if they actually were square).
