Perhaps I can help with these questions. First off, a
DVD holds 4.7 gigibytes of information. When making a
DVD for video playback I think the limit is, on some,
3.95 and on some around 4.2. The rest is used for the
menues.
As for a 45 minute video, a DVD should be able to hold
up to 2 hours of video depending on the bitrate video
quality. I am making a collection of Barney Miller
DVDs. I put 3 22 minute shows on each. I could
probably get away with 4 at a lower bitrate, but it's
all planned out for 3 so I am sticking with it. With
the menu structure each DVD runs around 3.25 Gig.
All DVD video MUST be an .mpg file. .AVI doesn't
work. Some DVD burners, or authoring softare will
accept .AVI files as stock video, but will do the
encoding when creating the DVD.
I have yet to see on this list a good suggestion as to
what the best way to encode video. (IE. highest
quality/lowest file size.) I use VideoFactory to
encode the files and DVDit to author the DVD into a
folder, then Nero to burn the DVD. I've looked at
TMPG, but didn't see any improvement. And it's
slower.
I keep looking for suggestions though.
