Widescreen Photoshop image doesn't import right

earthrisers wrote on 2/8/2009, 4:43 PM
For use in Vegas, I create images in Photoshop (mostly text and lower-thirds, but not exclusively), using Photoshop's "NTSC DV Widescreen" template setting. It looks right in Photoshop (16x9aspect), but when I save the image and import it into Vegas, Vegas imports it with a "1.0 -Square" pixel property.(My Vegas project is 16x9 Widescreen DV.)
I have to go into "properties" for the image, in Vegas' Project Media, and manually change the pixel setting to 1.2121.

Gets tiresome when there are lots of images.

Anyone know why Vegas doesn't import the images with the pixel aspect that Photoshop claims to be creating?

There is no mechanism for Photoshop to imbed the pixel aspect ratio in the image file's header. Since there is no way for Vegas to know, it just assumes that all graphics are square pixel unless you tell it differently.

Why don't you just create the files at a true 16x9 ratio in Photoshop and they will be correct in Vegas when it imports them with a PAR of 1.0? I make all my widescreen graphics at 1920x1080 and then they are valid for whatever widescreen video format I might want to use in Vegas.

I'll try that -- thank you.
I had thought that I have to use Photoshop's widescreen template in order to create an aspect-matched image for Vegas; but I'm still trying to get my head around this pixel-aspect stuff.
Gotta leave the computer right now, but will surely try your suggestion in the morning. Thanks again.

Vegas is one of the only NLEs that will try to make the file fit the format. This is one of the features that makes it a better editor. Avid and Final Cut are very particular about still image resolution and PAR.

I agree, just make the resolution of your photoshop files as 16 x 9. Vegas will handle it fine.

Note that NTSC Widescreen DV in Vegas isn't 16:9, it's 16.368752:9, for whatever reason. That works out to 873x480. True 16:9 would be 853.333333x480.

"That works out to 873x480. True 16:9 would be 853.333333x480."

And right in between the two lies 864x480, which is incredibly handy for sizing 16:9 Widescreen video for the web because both numbers are divisible by
2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96:

1728x960
864x480
432x240
288x160
216x120
144x80
108x60
72x40
54x30
36x20
27x15
18x10
9x5 which is it's true aspect!

Hope I got all those right!

Our life in the video production world would be a lot easier if they had defined Widescreen SAR as 9:5, rather than 16:9 which is an arguably ridiculous ratio, since it's only a difference of 1% in width, and 9:5 is simple enough to calculate in your head.

While we're discussing widescreen measurements;
Can someone please explain why ws ratio is 1.78 and the properties of HDV ws says it's 1.333? Is this apples and oranges?

"Is this apples and oranges?"

Yes. 1.7778 is Widescreen SAR, and 1.333 is HDV PAR.

A search on these forums will lead you to more discussion, and links to some very interesting tutorials.

Aspect Ratio, PAR, etc.

There is an interesting article about picture size at http://www.bbc.co.uk/commissioning/tvbranding/picturesize.shtml

This only applies to DV; for HDV there isn't any correction needed.
