Which one is from the original DVD? by linx05 on 07-18-2006 at 10:59 AM

I recently backed up a DVD, Toy Story. Here, I have two pictures, which one is from the original DVD, and which one is from the compressed?

I know, they're jpgs but it will have to do (couldn't do .png).

I say it's bq0.jpg. If you zoom in on Woody's fingers, they are clearly more defined.

Woody's Fingers - bq0.jpg
Woody's Fingers - dpe7.jpg

Plus the second image's filesize is smaller, and therefore, compressed. :P

I will tell everyone the answer after a few more posts/votes.

Fist picture. it's not just the fingers..but the whole picture has an overall difference which can be seen if analysed carefully.

I so will win at the game :rolleyes:

Look at the lighting on buzz's helmet.


RE: Which one is from the original DVD? by Chris4 on 07-18-2006 at 11:27 AM

First picture.

If you compare, you can see the colour on Buzz's costume is more brighter and colourful in the first picture. In the second, it's more dull.

The screen shot which came from the original is... number 2.

I used DVD-Rebuilder with HCenc and HybridFuPP to do it. Out of everyone who I've asked, only one has chosen picture 2, lordy.

Everyone (except shawnz) thinks picture 1 is the original because it looks clearer. That is not right, as you can see. HCenc did the compressing, leaving as many of the artifacts/mess out of it, while HybridFuPP cleaned it all up.

No, he's showing us what a piece of software can do so..
RE: Which one is from the original DVD? by Val on 07-18-2006 at 06:29 PM

Hmm I would think number one is the original since it is more clear and looks nicer :P

yeah... messing things up.... :p

If I take an original picture, compress it (thus making quality lower), then running even another peice of software on it to clean up the compressing (making the image less contrast and bright) I don't call that exactly positive.... :D

Does it look better to the human eye Cookie? Yes.

ermm... actually no...

How can a mangled and compressed copy of an already compressed format even look better (... to the human eye)? (unless you go for that effect of course, but we're talking about a DVD copy here). It doesn't make sense in theory and it doesn't make sense in practice IMHO...

By compressing, blurring, etc... you lose quality, you do not enhance quality.

A recompressed and edited copy of a DVD always looks worse than the original, even if your copy program applies some contrast filters and/or sharpness filters, it still would be worse than the original.


----

PS: and by comparing two still shots (and not good ones for the purpose of this test/doing this poll for that matter) you can not judge quality of a recompressed copy of a compressed format at all (let alone base that judgement on images which were again compressed from the compressed copy of a compressed format).
RE: Which one is from the original DVD? by surfichris on 07-19-2006 at 12:56 AM

I guessed second picture first off (without looking at any other posts).

It is pretty easy to tell (at least for me) based on the darker areas in the images as well as the fact I thought that Woody's hand was cleaner in the second image (ddunk).

As Cookie said, it is hard to judge the two still shots of a scene in a movie. You've taken a shot which is blurred because of the motion which makes it even harder to tell. You'd notice if you played back the whole scenes - and especially on a high resolution device (or good quality monitor - which is why it made it very easy for me to pick the second one).

Excuse me for saying this, but, derrrr. You'll always lose quality. But using different filters it can clean up artifacts the original had. Not all professional DVDs are authored properly you know.

I've performed the test with members of the family, and friends using the original DVD, and the backup copy. Nobody has been able to pick the backup copy. Everyone thinks it looks better.

I didn't use two videos from the DVDs because of legal concern (not sure if it would be <i>entirely</i> legal or not).
