ayu vob pvs vs. avi pvs
 

i'm sure everyone knows about the popular tracker from jpopsuki.com and the Ayu HQ PVs in the ahsforum. so, what are the differences of the two types (.avi vs. .vob)?

i've never seen any vobs appear in any ayu forums but i have seen vob torrents for ayu's pvs at jpopsuki. are they like the same? or are the vobs better than the ones that can be found here?

The .vobs are the DVD files

The .avi files are the regular videos after conversion and shtuff.

Hope I got that right.

^^I think so too...alrite..u stole my line .:P

And believe me, there IS a difference between the two as in quality. Atleast there should...

If the AVI were encoded nicely, both quality differences will not really visible.

Not to mention the aweful filesize of .vobs. But Chris is right, if the avi were encoded well there wouldn't be a huge difference.

There's lots of ghosting and crap that can be really noticeable, even with the newer codecs at high quality ^^. But in general, it's not very noiceable, nor is the size very much different if that's the case.

Like has been said, VOB is the original DVD files, it's as high quality as you can find the PVs. But many of the VOBs at JPS are ripped from DVDs that has been shrinked, so not many of them are the original quality.

Shrinked?... what exact procedure do you mean?... I don't think I've heard of 'compressing' DVDs or such...

.vob files are simply the DVD quality, which is high quality mpeg video.
.avi files are original DVD quality videos encoded/compressed using DivX/XviD codecs to reduce their file size without too much of noticeable image quality loss.

Difference between image quality of DVD video and DivX/XviD or such is usually always noticeable if you take a closer look at the image. You can make it almost barely distinguishable if you choose lower compression rate when converting DVD to AVI, but then the file size goes higher...

Depends on the original PV itself. I have D.D.D. feat. SOULHEAD by Koda Kumi that is at 20++ MB but the quality is almost the same with the one on my DVD. So basically, if the PV colors & contrast are high, much likely it will result in BIG size and vice versa.

then, are the videos provided at ahs' HQ PV files the highest possible .avi? i guess so...

so, is it soooooooooo good that the quality is practically the same as the .vobs that can be found at jps?

No, they are not. The files in that thread are some MQ.

mmm, VOB must be very HQ, as I know

You should look into an application called "DVDShrink".

They might not have to be. The highest quality AVI file would need to have a 99% or even 100% quality factor, but that would probably result in the AVI file being almost the same size as the .vob file.

I would find it easier to see the difference between .vob and .avi when playing it on the computer rather than when playing it on TV. Regular TVs make digital signal appear kinda smoothed, while LCD displays, due to their specifics, the contrast, reveal all the flaws of the image.

That moments PV is a vob file?

Did you burn it as a DVD video or do your DVD player support divx?

vob (or mpeg2) is a lossy codec, that means that the avi file, which was probably encoded from the original .vob file, will become even lower quality when you encode it to mpeg2 again.

It's like, if you encode a 320k mp3 into 192k and then back to 320k the quality of the new 320k file will in reality be much lower than 192k.
