You may also want to look into setting up
your project in 16:9 instead of 4:3.

16:9 gives a more filmic look due to the
aspectratio and is the format of choice
for most if not all of the recent productions
targeting broadcast and net. Most viewing
devices announced or buzzed have a somewhat
compatible screenspace, e.g. 16:10, 14:9, etc.

If you find this prohibitive due to rendertimes
or existing shots you may still check how your
footage looks with pan&scan or centercropping
due to the above "restrictions" of the targetdevices.

A nice format that isn´t too hard a punch in rendering
compared to square PAL (768x576, mind the overscan)
would be 1024x756 square pixel, e.g. 16:9, sometimes
refered to as PAL plus. Some people render this using
720x576 with a pixelaspectratio of 1,42 to save even more,
stretching things back to 1024x576pixel (square) in post.

Check out the adobe aftereffect 30day trial for quite a
comprehensive list of composition presets and also some
backroundinfo as part of the manual/help files.

That said, I do all my stuff in 1280x720, 25p currently...

Cheers

Hi all!
I want to make a video that would be broadcasted on TV and computers. If I choose XSI's PAL preset, I get an aspect ratio of 1.0667, as the D1/DV NTSC and PAL specifications specify non-square pixels (often called D1 aspect ratio), while computer monitor pixels are square. D1 pixels are vertically shorter. For this reason, when you look at a D1 video image on a computer monitor, the images appear to be squashed vertically.
Is there a way to make both TV and PC happy or should I render 2 versions of my work?
Thanks
David
