Thanks.  The AGK search I did mostly led here.   :laugh2:

End file sizes are all completely dependent on what you are compressing.  Can we assume you're talking about a DVD movie that can range anywhere from 2g up to 8g on average?

Yes, DVD movies. Sorry. Forgot to mention that.

I did a test with Green Mile since it is a big one. It is about 7 gig uncompressed. So I did a 1 gig and a 75% compression. The 75% came out to be 1.9 gig. I am going to go home and check the quality on the xbox and the big screen. I was just curious if you guys set a % or a size limit. And if you used AutoGK or something else. Any more comments are appreciated.

Thanks.

I don't use anything but do have experience with video compression and the like, so what I say is based on that rather than DivX or AutoGK specifically.

The first big factor is going to be stuff like special features, which audio portions you keep, and to a small extent subtitles.

Are you just going with the usual full movie, 5.1 and 2 channel stereo?  Does DivX support DVD menu style functionality for including the special features or is it straight video/audio?

Actually, I was just going to rip the movie itself with the default audio file. We don't watch the extras much and we never use the subtitles so I let those go. I am not as concerned with audio as I am with video. I have a 50" tv and I want it to look at least pretty good. Sometimes I rip the extras seperatly. Like if I rip a TV show dvd. I rip all the episodes seperate and the extras seperate. So my main concern is video I guess. Again, just curious if you guys go with a size limit or compression % limit.

I am about to check out my two tests. I will let you know what I think of them.

No, I don't generally do that.  But keep in mind that the player you use is about as important as the compression quality.  One could easily assume that they would play it all back the same but they don't.

My recommendation is go with a % limit.  You'll get much better consistency that way as it will compress all source at roughly the same rate.
