Best Picture smallest avi file size?

I'm looking for the settings that will record the best mpeg-4 picture with a
file size of 350 to 400 megs for 45 minutes. I have downloaded several
shows with really impressive quality at that size but cannot find a decent
setting to record them myself.

Perhaps I should be using a higher bitrate then some compression software to
produce the smaller higher quality file???

Any suggestions would be appreciated.
 
You'll want to use the DivX codec with m-pass encoding to ensure the maximum
quality to file size ratio. Goto www.doom9.org and start reading.
Personally, I use gordian knot for the .avs setup and bitrate calculations.
Then I actually encode with divx5enc503 and HeadAC3he. The end result is
pretty much the best DVD rips you can get.
 
XviD is also worth a try. Gives comparable quality as DivX, and is free.

Plus with DivX you really need the Pro version for best quality, and that
isn't free (or is adware). Doom9 has quides for XviD aswell.
 
Thanks both of you,

So I guess from the sounds of it no one is using the multimedia center that
comes with the all in wonder cards to actually capture video?

Guess that explains why mine are so bad. <g>

Isn't that an analog capture? If it is, analog would be lower quality than
a digital rip.
 
Don't have AIW myself, so I'm not sure which format it encodes to (I
seriously doubt it is mpeg4, since there isn't a PC powerful enough (yet) to
encode realtime in to mpeg4 (using the highest quality settings), plus you
can't obviously make a multipass encode realtime).

What I'm suggesting is use the lowest possible compression when capturing
video. This will no doubt create a huge videofile, but it will be highest
possible quality for that particular capture device, yes? This file can then
be easily encoded again to DivX/XviD format, with little or no quality loss.

Using a bitrate calculator I'm getting: 45 minutes/350MB/192kbps MP3 =>
appr. 900kbps. Anything above 800 gives a crystal clear image for both DivX
and XviD so you should have no problems achieving high quality, but of
course the original source has to be high quality too.
