I have a video project I intend to distribute on both blu-ray and standard DVD. I'm planning create all the menus and buttons first for the blu-ray disc. Can I just downsize the menus and buttons in Encore when I go to create the standard DVD? Or am I better off recreating the standard DVD menus in Photoshop? Has anyone else needed to create the same menus for both br and standard DVDs? Any tips? I'm using CS5. Thanks.
I'd certainly agree with Jim's answer above too.
The problem with trying to use the same image is not so much the massively different resolution (1920x1080 against 720x480) but also the pixel aspect ratio.
BD uses square pixels, and what you design is what you get in the disc - DVD on the other hand uses non-square pixels and this can be a design nightmare if you attempt to scale HIgh Resolutiom images down to SD.
Also the button SPHL are different - BD requires a separate layer for each button state in up to 256 coloiurs whereas DVD gives you the whole lot on one 2-bit indexed image with a total of 3 coloirs.
I would definitely suggest creating separate menus for each project.
