NTSC via PAL confusion

[Jonathan Ziegler]

It sounds close, but I always thought DV NTSC Wide was 720×480 x 1.21 pixel ratio (1.2?).

Not sure if it will work, but can you convert to a square-pixel 16×9, then convert to DV NTSC Wide? I’ve never shot PAL before – dunno if there will be a significant generation loss. Was thinking since PAL has more vertical resolution, you may want to preserve as much of that as possible before converting to NTSC Wide.

I’m curious if this is even valid. Anyone else?

[Dave LaRonde] “Almost every such player made in the past few years should be able to play NTSC DVDs with no problem.”
Hi
If its set up so to do, but unfortunately not every TV can play the output of the DVD player properly.
Especially if the DVD player is outputting NTSC 4.43 as PAL 60 scaled into a 720×576 raster.

[Francis Hughes] “Hi,

Before anyone says, yes I have searched the forum on PAL to NTSC, however I really need some clarification if anyone can give me a few minutes of their time to reply.

My project is SD PAL Anamorphic 720×576 25fps etc, I need to go to SD NTSC Anamorphic and produce a DVD for the USA. I’m going to use compressor to achieve this as most posts seem to recommend it.

My question is that I’m lost when it comes to what pixel aspect ratio I should be and frame size. Is 720×480 correct and the pixel aspect ratio 1.1250 (compressors settings when doing NTSC 8bit uncompressed) and that when it is played in the States on a 16:9 capable TV that it will appear 16:9?

Being UK based I have no way to check the DVD before sending so it would be great to get it right first time. Thanks for reading and any help you can give!”

Just to clear this up again, computers can display DVDs in either format. DVD players feed media to a TV which is the device that ultimately displays the media.
NTSC TVs will not display a PAL DVD, you will need to convert to NTSC, and author in NTSC before formatting.
NTSC TVs cannot display both formats, modern PAL TVs can.

Cheers
Alexander

Thank you so much for replying everyone that has really helped me out, light at the end of the tunnel!

Oh dear just when you think you have it sorted…

So I’m looking at the settings in Compressor and I have it set to NTSC CCR 601/DV (Pixel Aspect Ratio of 1.1250)

But I also see I have a NTSC CCR 601/DV (16:9) (Pixel Aspect Ratio of 0.8438)

If I want my video 16:9 which one do I choose!? The resolution is 720×480

As Dave said I set my Pixel Aspect Ratio in DVDSP, but depending on what option I choose here it must have an effect?

[Francis Hughes]

Oh lawdy. Thanks again Dave.

I think someone somewhere has a lot to answer for.
