Video Resolution Vs Compressibility AutoGK

[firies2006]

which is more important, a high resolution or good compressibility when it comes to encoding a DVD to an avi file?

i want the best possible quality for my encode and just dont understand why compressibility is important. the higher the resolution used, the better the quality of the resulting avi file, right? so what does it matter if the compressibility is low?

basically what is the benefit of having an encode with a good compressibility percentage? please be gentle as i am new to this.

Hi-

having viewed the two avi files and comparing them, i can definitely see that the first encode is much better visually than the second encode. my question is this:

I would dispute that. While the first one might be sharper, it would surely be much more artifact ridden. A final compressibility percentage below 38% is pretty low.

so what does it matter if the compressibility is low?

It matters quite a bit, which is why AutoGK tries to find the happy medium, even when you do silly things like take up over 300MB of a 700MB CD with AC3 audio, and force the width to 720. Juno isn't the kind of movie with a lot of surround effects the way an action film is, and the AC3 isn't really necessary when space is at a premium.

Perhaps you don't know the kinds of things to look for. Try and find a scene with a lot of movement, maybe pretty hard with Juno. Pause it and start advancing a frame at a time. You might see such things as mosquito noise (lots of dots outside the "lines"). color smearing, and, worst of all, macroblocks, the colored squares indicative of too low of a bitrate.

i want the best possible quality for my encode...

If that's the case, do a Target Quality 1-pass encode and forget about doing a 1 CD rip with AC3 DD5.1 audio.

By the way, the Juno DVD isn't out in the US for another couple of days. Is your source a retail DVD? And you got an NTSC version of the DVD in Germany already?
