Sorry what is PAR?

Manta, it's really a mess, were not actually producing the video that will be done by a marketing company that has yet to be picked by the client. Basically I'm just providing the animations and they are going to assemble it so because we don't know who were working with yet I don't have any idea what there using.

I believe PAR is pixel aspect ratio...

I would suggest doing some experimenting, and make a dvd yourself...use something faster than maxwell for the experiments though...

I'm a PAL guy, so I hope I'll not mess up the numbers ;-)

For NTSC widescreen the final output will have to be NTSC widescreen MPEG2.
I think the numbers above are right... in which case it's 720x486 with a pixel aspect ratio of 1:1.2

If your render software can't do different pixel aspect ratios, then you can render to 864x486 in square pixels, and the image covers the same size, so you will have no stretching or cropping issues later.

The exact sequence of what you need to convert and when will depend on the way you produce the final edited source for the MPEG encode, and what software you encode with.

Either way there should be no disadvantage with rendering at 864x486, other than the loger render times.

EXCEPT

if the encoding software forces a PAR on you. You need to test these things. Make a test frame at 864 x 486 that has a circle in the middle going from top to bottom, and another shape, maybe an oval, that goes from the left edge to the right. Make it a 10 second 'clip' and export it as if it was your final footage. Check the result for cropping and proper proportion. Then you'll know for sure what you're doing.

What's the answer on Maxwell and non-square pixels?
