Many thanks to len0x for making a diffcult subject easier to follow. I may actually learn more about the process, as I can follow it happening.

riddle#1) I've got an Averatec 3200 series laptop (1.6ghz AMD\w a very slow bus), that will encode Nero ASP at 3-4x realtime. Using Xvid with AutoGk is taking about 5-6x realtime. Am I probably doing something wrong? I thought Xvid was faster?
I like to backup music videos and theatrical movie trailers. I have been keeping the file sizes around 40% of the original or about 2-3 mbps. I have the latest version of Xvid and it looks better than anything I've encoded with Nero's ASP.
Is it possible for AutoGk to use my Nero ACC? I'm not a programmer, or I would try it.

Quality never comes for free, so its perfectly normal for XviD be slower that Nero. What is Nero ACC?

ah...um...I think I was meaning HE AAC? Sounds pretty good, whatever it is. Thanks for the reply. It doesn't seem that encoding should take so long, but I see alot of users here have some xspeedy machines.

I guess AAC wouldn't fit with the .avi container very well huh...

no, but avimuxgui can put AAC in AVI with no major drawbacks.
so:
1. download avimuxgui
2. encode the audio with nero and demux it to raw AAC
3. take note of the filesize
4. choose a final filesize for your encode and subtract the audio filesize
5. round down the value you obtained, this should compensate the overhead (for example 638MB->630MB)
6. encode the video ONLY with AutoGK using your custom filesize
7. mux audio and video with avimuxgui

Can't be that simple. This new version of Xvid is gonna rock with AAC.

That said, I've noticed that decoding high quality .avi is a burden for the ol'Averatec. It plays, but all the memory has to be free. Is AVC any better in this respect?

[wrocnrob]

encoding the audio in CBR mp3 works better for decoding than VBR-- somethin to do with overhead I think; I've yet to try AAC with avimuxgui.
Nothing seems to match the fluid playback of the original mpeg2 stream, they're pretty sharp on a 12" screen. I might just use these instead of transcoding.
