I am scanning photos to make a slideshow DVD in widescreen format.
Photoshop gives the required size as 720 x 576 pixels but that is clearly wrong.
576 seems to be the correct height but 720 is not the correct width. 
What are the correct sizes  ???

Cheers.

720 x 576 is correct Fergie.

It's a little difficult to explain quickly, but it's not to do with the number of pixels but the aspect ratio of the pixels (PAR) themselves.

Take a look at these two Adobe support links, they are much better at explaining than I am, albeit with an American accent smiley

768 x 576 is the correct SQUARE PIXEL size for a PAL DVD.
Make them this size in your image programme and in Premiere they'll look right in a  PAL D1 sequence.
What version of Premiere are you using?

Re: Widescree pixel size

We seem to be at cross purposes here guys.
My problem is in Photoshop, not Premier.

If I open a new background set to 720 x 576px and then crop an image to those same settings, I get an image that looks more lika a 4 x 3 setting rather than a widescreen setting.
As a result, the 720 x 567 image will not fill a 720 x 567 widescreen background.
It will however fill the widescreen background if the image is cropped to a size of 1025 x 576   ??

Cheers.

Sorry, my mistake: didn't spot that it was a widescreen project.

Your problem is not in Photoshop, but has to do with the fact that PAL DV pixels are not square, but rectangular.

The links that Wiz sent explain it all.
 

But short answer, 1024 x 576 and with square pixels will give you a PAL widescreen image.

Re: Widescree pixel size

In Photoshop I'm trying to crop still images to fit a widescreen TV.
Image attached show a new 720x576px widescreen background.
The photo was cropped to  720x576px and should therefor be the same size as the background.
It's not ??????
That's the problem.

Try cropping your original image to a 16:9 ratio image then resize you image to 1024 x 576.
