On the advanced tab>"source aspect ratio".

What is the differance between the 16x9 and 16x9 525 Lines (NTSC) settings?

Thanks,
Bret

Depends on what output aspect ratio and which video arrangd method you pick. If the source is NTSC, and if the output is 16:9, then you can select either one (16:9 Display or 16:9 NTSC), and the result should be exactly the same.

If you are converting from 16:9 to 4:3, or resizing the image in some other way, TMPGEnc needs to know the pixel aspect ratio, and it determines this based on the option you choose. Although the image in 16:9 PAL has the same aspect ratio as in 16:9 NTSC, the pixel aspect ratio isn't the same.
