Pixel Ratio

Robert-Costo wrote on 1/9/2022, 12:39 PM

I have Movie Studio Platinum 15.0 and in My Project Settings I have My Project Template Set to HD 1920X1080 and this is what I want.

But I do want it to be Widescreen so I go down to the Pixel Aspect Ratio Box.

There are 2. Settings that I did not Understand?

One Says 1.2121 NTSC Widescreen and the other Says 1.3333 HDV 1080 can anybody Tell Me witch one I pick and why?

1920x1080 is widescreen 16:9. Your pixel ratio needs to be 1.0000.

Thanks for the help.

But it Says 1.0000 Square?

Correct. 1.0000 is square. But it's the pixel that's square, not the final image. That will be 1920x1080 square pixels which is 16:9 widescreen.

Just do the simple ratio math:

1080/9x16x1.0=1920

One Says 1.2121 NTSC Widescreen and the other Says 1.3333 HDV 1080 can anybody Tell Me witch one I pick and why?

Those are the legacy anamorphic pixel aspect ratios for obsolete video tape cameras. They do not apply to your project in the least. The correct settings for FHD Widescreen are 1920x1080 1.0 PAR.

This is an excellent place to begin your learning curve.

Well if I Select 1.0000 Square for the Pixel Aspect Ratio and not the NTSC DV Widescreen 1.2121 how will it know to make it Widescreen?

It just Says 1.0000 Square not NTSC DV Widescreen 1.2121 so why does it not have to Say it?

Read Musicvid's post above carefully.

As he said "The correct settings for FHD Widescreen are 1920x1080 1.0 PAR".

Because 1920x1080 is 16:9 Widescreen?

hank You for all the help.

Here's a quick brushup on ratio math:

The lowest common integer factor of 1920 and 1080 is 120. There are as many ways to figure this as there are middle school math teachers in the US. One of the best I knew started as a theater projectionist 😉

1920 / 120 = 16

1080 / 120 = 9

-- or --

1920 / 1080 = 1.777_

Therefore: 1920:1080 = 1920/1080 = 16/9 = 1.777_ DAR, 1.0 PAR (Square Pixels)

I know for a fact that 98% of us lost this essential skill promptly on entering ninth grade. However, it is well worth knowing if one wants to create movies of any sort.

Of course to further cause confusion SD widescreen isn't true 16:9. It's actually slightly wider!

And DV Widescreen and DVD Widescreen are slightly different.

@Musicvid I didn't know that. What's the difference?

It was in the NTSC storage dimensions Eric, and I still get them all mixed up. 704x480, 720x480, and 720x486 were all valid NTSC formats at one time. NTSC DV Widescreen IMX was 720x486, and NTSC DVD Widescreen is 720x480, both with 1.2121 PAR (I had to open up an old copy of Vegas to recall that). Anyway the result was thin pillarboxing, and Vegas now has a couple of ways to deal with it. I reckon things are a bit more predictable in PAL land.
