Aspect Ratios – 2.39:1 from 16:9 (1.78:1)

[Jeff Schroeder]

Will,

Are your pixels square? If they are you are going to give up nearly 60% of your height. You will set a project size of 1440 x 600. Then you must ‘match aspect ratio’ on all your video events. If your footage is anamorphic and was recorded at 1440 but meant to be viewed at 1920 then your going to loose less of your height you will set the project dimensions at 1920 x 800 and pixels at 1.333.

You must find an output format that will support this frame size, which is not too hard, just try making your own preset in Sony AVC.

Let us know what you come up with.

[Jeff Schroeder] “…you will set the project dimensions at 1920 x 800 and pixels at 1.333.”

I believe you meant to say “use square pixels”. 2.39:1 is 1920 x 803 PAR 1.0.

I thought I had it right! If the actual number of pixels across are 1440 and are meant to be viewed at 1920 then would not 1.333 be the correct setting?

I don’t work much in 1440 (maybe once or twice) so go with John’s advice. He has more varied workflow than I am used to.

Hi guys,
Its been a nightmare but I have done it.
OK, in project settings I used 1440×800 using 1.121:1.
In the crop settings I used 1440x865 as if you use 800 you get black bars?

For some reason you get tiny black bars in the viewer, top and bottom, but when rendered in BR 1440×1080-50i but in custom options changed the 1080 to 800 and the aspect racio to 1.21:1, it looks pefect.

Do you think that is OK?

Will.

addendum: Right John, 1.333 would be the event’s pixel dimensions NOT the project! Thanks man.

Yes, the correct setting would be 1440 at PAR 1.3333 but you said 1920 at PAR 1.333. It can either be 1440 @ 1.333 or 1920 @ 1.0 but you can’t mix them.

Where did PAR 1.2121 come from? That’s the PAR for NTSC SD Widescreen. I thought you were using HD?

If you want it to work properly, set your project to 1920 x 803 PAR 1.0 and add a Pan/Crop to all of your media using Match Output Aspect.

Hi John,
Thanks, the PAR 1.2121 is from the render settings.
I cannot render out PAR 2.39, as I don’t have that option, only square, 4:3, 16:9 and 2.21.

Strange that you cant have any other Aspect Ratio when rendering?

I will try what you said and let you know.
Thanks.
Will.

[Will Brown]

Ok, I see, with 1920×803 PAR1.0 in project settings, I have to use 1440×803 in the crop window.

So when rendeing out, I have BR 1920×803 50i, 2.21 and I have black bars, 16:9 and they are worse.
Do I have to change the 1080 to 803 and the Aspect Ratio?

Thanks John.
Will.

You are confusing Pixel Aspect Ratio with Media/Project Aspect Ratio. They are complete different things.

You said that you wanted to render an aspect of 2.39:1. That is not a PAR. That is a ratio of width to height where the width is 2.39 times the height. It has absolutely nothing to do with PAR which the width of each individual pixel on the screen. This is why you are getting confused.

There are two ways to achieve 2.29:1. You can leave the height as 1 and multiply it by 2.39 to get the width:

1080 * 2.39 = 2581 x 1080

Or you can keep the width and calculate a new height in which case you divide the width by 2.39:

1920 / 2.39 = 803.34 (or 1920 x 803)

In both cases, the PAR is 1.0 (square pixels)
