slideshow bitrate-how low can I go?

mtnmiller wrote on 9/8/2007, 7:43 PM

I'm putting together a DVD with a video and slideshow. Rendering the video as an mpg-2 at an average 6m bitrate leaves me with not much more room on the disc for the slideshow.

I'd rather not go below the 6m avg for the video (or have to do a two-pass encode), but what about for the slideshow (where there is some pan/crop movement on most slides)?

How low an avg bitrate can I use for the slideshow while maintaining a decent quality?

thanks for any input

I've gone down to 4 VBR with 2 pass encode and couldn't pick the difference.
With V7 you can put a marker at every cut and force an "I" frame there which should help no end. Needless to say at such low bitrates keeping the motion slow helps, regardless stills flying around the screen isn't such a good idea anyway. Really, really slow zooms (creeps) are very effective and will not stress the encoder.
