Hi

I have created a menu for an SD PAL DVD, in DVD Studio (v 4.2.2) pro by the following method:

-In photoshop created a menu design on a canvas of 1024x576 pixels at resolution 72DPI.
(menu consist of a simple logo and then 2 film titles of black text on white)
-Flattened the image and imported into DVD studio pro.
-In photoshop created an overlay of grayscale on transparaent with icons needed the buttons.
-In DVD studio pro the menu is set as the menu background and the overlay with icons is used for the buttons.

The menu background and button icons all work fine but the quality of both of them both looks awful, very pixelated and like its low res. However in photoshop and any other image viewer the psd files look fine.

I have tried the following:

-creating the psd files at 300 DPI.
-Saving the files as JPEG and TIFF instead of PSD.

But this makes no difference.

Any advice would be appreciated.

Thanks

Ceri

PS has presets for video screen resolution. Start with the correct resolution for PAL 4:3 or 16:9. Your resolution is wrong, You must bring in the correct resolution. 72 dpi is correct.

Yeah you do not want DVDSP to do any resizing to your menus. Also you'll find PSD based menus are very limiting in terms of performance. Read your manual about the single layer simple highlight method instead- that's what most DVDs use.

She says her resolution WAS 72dpi and she just subsequently tried 300dpi which then didn't help.

I have the same problem with imported logos looking 'jaggedy' when imported to DVDSP whilst looking fine in PS. Background produced in PS at 72dpi and tried importing different file types (inc JPG/PSD/etc) all to no avail.
I've checked canvas size matches DVD res (i think) but it looks like rescaling is maybe going on.
Does anyone no what the correct canvas size should be for PAL 16:9? I've been using 1280x720 (since my DVD playback is HD720 16:9) but im wondering if this is where problem lies.
Grateful for any advice. Thanks.

1024x576 square pixels. This needs to be resized to 720x576 anamorphic pixels before importing into DVD SP.
Or rather start with Photoshop preset PAL Widescreen 720x576.
