Ok
This is copy from Scenarist SD User Guide:
Still images for 16:9 Widescreen
When creating still images for a 16:9 Widescreen project, special steps are required to ensure that the images are displayed correctly. You should create the images initially at a resolution of 960 x 480 for NTSC and 960 x 576 for PAL.Then, just before importing the image into Scenarist SD, resize the image to 720 x 480 for NTSC and 720 x 576 for PAL, therefore recreating the anamorphic squeezing effect that is performed on widescreen video. When the content is played back, it will be stretched back to its original widescreen aspect ratio.
100% this work with DVD Architect 🙂
! after resizing images to 720*480, you’ll need to apply 0.5 pix vertical blur to reduce flickering
OR may be….you can use software for creating slide-shows?
ProShow, Imaginate etc – create video file with transitions, effects and titles?
