how to increase image quality of photo album

I tried to author a DVD containing homemovies and photos. After using Photoshop to resize the digital photos to high quality bitmaps of NTSC size 720x480, I used Adobe Premier Pro 1.5 and EncoreDVD 1.5 to author the DVD. The result was disappointed because the images look highly degraded. So I thought of using a photo album software to create a DVD slideshow, then export the photo album DVD to AVI and reauthor the final homemovie DVD. I tried a few photo album softwares such as VOS Photo DVD, DVDSlideshowGUI,.... The slideshow images they produce are of the same quality, and look much worse in comparison the the source BMP pictures. The images lose lots of details. Anyway I used those images to build the homemovie disk. On the resulting DVD, the picture quality of the video looks much sharper than that of the photos. That's a big disappointment, because the source NTSC bitmap photos are much sharper than individual video frames. Can anyone recommend tools or ways to improve on this, to make a digital photo look as sharp as the camcorder video when authoring them together on a DVD? Are there tools or ways to do that, or what I got is as good as it gets? Thank you very much.

Did you use your original photos in DVD slideshow GUI? It will do the scaling for you... I've added a minor blur in the end of the temp avs file because people would get flicker on sharp thin lines showed on tv. Maybe this is not needed for your pictures? So try to export to .avs, open the file in notepad, and delete the blur line in the end of the script, save it as .avs and render this file in Quenc. BTW. if you use the animation tool and you zoom into a an image which is not bigger than the frame - then the image will get more and more blurry the more you zoom into the image. Good luck, Tin3tin

Hi Tin3tin, I'll try your suggestion sometimes this weekend and see what happens. I'll let you know. Thank you very much.
