I think I have a method that works, but it appears to increase the
height of the image. Is there a way to restore the proportions?
I render the NTSC avi file in Premiere as a PAL file, which appears to
conver it and then burn it to a DVD using the PAL settings.
I'm assuming it's the increased number of scan lines, that's doing it.
Any suggestions other than cropping the image?

buy canopus procoder lite and use it to do the conversion.
or just burn an ntsc disk , most pal machines will play it back just
fine.

I think you mean "clipping" rather than "cropping". Cropping removes lines
from top/bottom/sides of image, then expands the resulting image back to
its original size. Clipping removes the lines and ends up with a smaller
image.

| Before you start doing it and have all the headaches related to conversion
check if your DVD won't work properly with PAL as is. My cheap Apex tabletop
player will display PAL video properly on NTSC TV without any conversions
whatsoever. As a matter of fact they all should do it since it's pretty much
function of software and just about any larger video company will be selling
models on both markets and therefore have lower productions costs if all units
were the same. Albeit for some strange reason logic doesn't always apply here
and for example worldwide supplier of video equipment, Sony, has DVD NTSC
models that will not work with PAL discs nor will support all sound codecs
defined under DVD standard (some codecs are mandatory for PAL but voluntary for
NTSC). That's one of the reasons big names no longer mean anything and often
enough guarantee inferior product. Part of the reason could be Sony owns movie
studios and cares more about protecting it's interest there than providing
good, flexible video products.

| DVD is video I created that has to go off to Greece. They specify PAL.
I took the NTSC files, and re-rendered them in Premiere to PAL
standard while at the same time I adjusted the height using the
"transform" tool to 83.333 percent (576 x X =420 therefore X = 420/576
or .83333), I then burned the files using Sonic "My DVD" checking PAL
as the preference. It looks pretty good, but they look a little
squashed down, not much, certainly good enough for a preview copy,
which is what I needed.
I would like to know if there is a better, more accurate way.

| A couple more thoughts from my semi-literate mind regarding your squished
picture:
Have you considered pixel aspect ratio change within Premiere? (0.9 for
NTSC and 1.0666 for PAL)
What about Premiere's "Resize" effect to go from 576 to 480 lines? Adobe
claims this provides better quality than resizing via codecs.
Of course, I have no idea how these are actually accomplished within
Premiere.

| It appears that the resize, if empirically done, should be 91% I'm not
sure why, but if you go from NTSC to PAL in Premiere and set the pixel
aspect ratio to PAL, you need to use the "transform command" to squash
the heigh down 9% so that things like wheels and spheres look right.
If anyone knows why this odd percentage, I'd be very interested.
