Last week I made a DVD slide show with Roxio. I added an AC3 music track along with the pics each pic with a delay of 4 seconds. Surprisingly, since I haven't used Roxio in a long time (it was a gift), the DVD folder it made was loaded into DVDshrink W/O any problems. I created an ISO with Shrink and burned with ImgBurn and the DVD came out good --The file was about 4 gig. Just screwing around last Night I took that same DVD folder and imported back into Shrink, set DVDshrink to still pictures and then made another DVD folder. Everything came out the same, the AC3 music track is still good, the Menu is still good and the DVD slides look good, but the Dvd Folder file size has been reduced from 4 gig down to 488 MB. (no pics appear to be missing but I only watched about 10 min of the little over an hour production. I just wondered if anyone else has used the Still picture function of DVD shrink to reduce the size of their DVD slide shows, and if so, can you bank on about a 1/4 reduction in DVD file size?
It seems like a free lunch, because if you do the same to a a movie title, DVD Shrink decimates the frames so that 2000 frames is reduced to 200 (of course the movie plays like those WW1 shots of the boys going over the top of the trenches).
With a slide show, the size is reduced but the number of frames doesn't change and it seems to have no effect on the playback.

Yeah, I noticed that on the DVD folder I made with a simple dissolve between slides vs no transitions. If you use the Still Picture function in DVDshrink to reduce a slide show size, you can't use any transitions between the slides in the original. When you say "decimates" (reduction of 2k frames to 200) does it constantly grab one frame out of every 10, frame 1, frame 11, frame 21 etc, or is it based on some some kind of drastic image (scene) change in the video (variable). just wondering.
I was throwing out a general term, not literally.
The file I used was a one minute clip with 1827 frames reduced to 122.
Shrink says it takes stills at .5 second intervals, so I suppose at 29.9 fps it would be every 15 stills?
