This actually kills the advantage of the large GOP structure, because every time an I frame is inserted, there are no predictive frames to compare.

I just downloaded the new template, and it appears that the "detect scene change" is still enabled.

Anyway, I'll try this template on a 103 minute film that's been giving me problems, and I post the results.

Kwag, first of all, i'd like to say "you 'da man!" Your templates are awesome and thanks for all your hard work and time you've put into this. I just have a question about your new template. I've encoded two movies with your new template, Dazed & Confused and SNL's Best of Chris Farley. The first was 103 minutes and came out to be over 900 megs. I lowered the CQ to 74 (if i remember correctly) to fit it on one cd. So, there I am encoding twice again. In your first post about the new templates, it said one of the benifits was not having to wonder if the resulting file would be too large or not. So, then i encoded the Chris Farley one. This movie was only 63 minutes long and not a very high action one. I used all the default settings and the resulting file was 702 megs. Doesn't this seem like a short length of a movie to produce 702 megs? I guess I just don't see how you could ever fit 120 minutes on one cd using the default settings. For both movies I used smartripper, DVD2AVI, and then feed the d2v file directly into tmpeg. Am I missing an important step or something? Once again, thanks for your help and superior knowledge of vcd's!

When you feed the .d2v directly to TMPEG, every little noise that you can't see, is fed to the encoder. Remember, you're encoding from a DVD source, but there are macro blocks, even if your eye can't see them.
Not like the original material that was done to generate the MPEG-2 in the DVD, which is uncompressed video.

Use an AviSynth script with TemporalSmoother(2,2) and you'll reduce from 200KB to 500KB per minute.

That makes a huge difference in your final mpeg.
