[QUOTE=kingIZZZY;2168393]I could technically use 9999 Mbps then, because the slideshow isnt so long and i can fill up a whole DVD. My question is, wont high bitrate become excessive and unnecessary at some point and it wont add anything to the quality, because i’d optionally want to fill up the DVD with other extras.
To illustrate, i’m imagining that for example maybe encoding the slideshow at 5 Mbps would bring the photos quality to its best-ever-possible potential, and anything lower will make poorer quality. Encoding at 8 or 10 Mbps is also feasible, but won’t do any better in quality than 5 Mbps, and thus will pretty much just waste space which i’d like to use for optional content.[/QUOTE]
One technique that works pretty well is to encode it at max bitrate, (figure 8k), then if you want to shrink it later on you can use DVDShrink to bring the size down. Shrink will do a better job than initially encoding at a low bit rate, because it does use variable bit rates.
