AutoGK and HDTV conversion (say 700megs/42 minutes): Best Codec? AutoGK? Profiles?

[sjchmura]

So is the MAIN profile used for

AUtoGK 2.01
XVID 1.1beta
AC3
Autowidth
768megs/42minutes

is this about the best we will do or would taking the plunge, learning "GK" and using some other profile sreally help alot?

According to forum rule 12, there is no such thing as "best". Your post is ill-formed and therefore cannot be answered.

I don't know squat about HDTV, so I'll just give you a couple of side advices:

-AGK is now 2.02
-AC3 rarely ever fits on 1 CD, so count at least 2
-XviD would seem better suited indeed to keep details in
-If you plan on keeping the high res, count more in DVD output size than CD size.

Other than that, as Auto-Gk is Auto-matic, I can see no reason to fret and I'd let it handle the stuff itself :)

So a more specific question - one I have failed to find - is if we look at PSNR data does AuotGK with HD content do about as well as "tweaks".

You are right - "best" can be subjective. BUt we can all agree XVID 1.1 beats out MPEG1.

AC3 2.0 is actually not THAT big - 192 - so Enterprise episodes look stunning reduced to 960x540 (from 1920x1080i) 24FPS progressive with the AC3 intact.

AutoGK )n their site) is 2.01b. Where is 2.02?

I currently encode my HD episodes (original 1920x1080i, AC3) down to 1280x720p, original AC3 @ 1100MB. 4 episodes fit onto a DVD and the video quality is awesome! At the cheap price of DVD media these days it seemed like the right choice.

THis seems reasonable. I think I have settled on 960x540 (direct multipleier at 768megs (6/DVD) for a number of reasons

1. The new DLP sets I want are 1080p thus the upconvert will not induce errors
2. Fewer resizing problems going to 1/4 rez.
3. TO be honest, I tink the 960x540@768megs looks better on my current 1080i set - fewer fast motion artifacts.

But I agree - I was clsoe to 3/DVD at 1400megs 1280x720p :)

I wish nero was easier to use - the AVC is awesome (but slow)
