square or not to square
Hello.
I’m making files in photoshop that will be used by someone else(ie Client) for DVD menus. The DVDs are Pal 3:4. Should I make my files 768 x 576 square pixels and then convert to DV pal aspect ratio? or sqwish to 720×576 pal square? Can anyone clarify this for me?
Thanks in advance. Your all really cool!

Design at 768×576 and then resize to 720×576 without constraining proportions. But if you are designing menus for a DVD that someone else will author, always touch base with them on specs first, just to make sure that what you are doing works with the software they use.

My client has asked for me to supply files 720 x 576 square pixels. So I shall do this. But It seems to me, that if a file of these specs is converted to dv pal aspect ratio, the imagery would be stretched, lowering the quality. Am i miss understanding how this works?

When correctly prepared artwork is seen on a video screen, it will appear the same as what you designed before you resized the artwork (the video screen will match the 768×576 pixel version). This is particularly noticeable if your artwork contains any circles, which become ovals if the artwork is not handled correctly. All of this happens because the pixels end up as being not square when displayed on a video monitor, due to the physical height of the scan lines. The pixels are wider than they are high in PAL and higher than they are wide in NTSC displays.
