DVDShrink encode using No Compression?

[mrloofer]

This might seem like a stupid question, but does DVD Shrink do anything to the video when used in No Compression mode? I made a back up of a movie that was able to fit entirely on a disc using No compression. Comparing the two on playback, the backup look a little softer to me. Perhaps I am seeing things??

Thanks!

It decrypts the video, much like if you'd ripped with DVD Decrypter, but since your disc wouldn't need any decrypting, it would just be a straight rip. You ARE indeed seeing things.

Ok, just thought I'd make sure I wasnt going mad!

DVD Shrink does nothing to a video with no compression. The videos would be exactly identical.

You ARE going mad, you already admitted the copy looked softer to you. :P

[Cunhambebe]

Please open DVD Shrink and take a look at the small box that says <No Compression> and find out the size of your file...If you're using a sinle layer media, this file must be smaller than 4,something GB to fit on a single disc. And yes......you're seeing things

Hi, I can tell you straight away why you DO SEE different results..........its the media.....(and not any compresion via DVD-Shrink).

I posted a similar topic about 6 months back about different media giving sharper/softer video images (not many people replied , maybe there all blind?)..DVDr media IS NOT DVD-VIDEO (a la a 'real' DVD movies) and because of this DVD 'players' do not FULLY read the information on a DVDr (they have in built error correction) so they only display (at the TV end) the info THEY can read from any given media..hence the 'softness'...to all intents the DVD player is reading (and playing) the DVDr BUT it is not interperating ALL the data to a TV signal, ony some of it. Try a different make of DVDr (and media code) and I will assure you will have different results..... the 'trick' is to use a media that YOUR DVD player 'likes'.

Oh boy...

DVD is a DIGITAL format. Nothing more should have to be said, frankly. If your player has trouble reading a particular disc, whether it be a pressed disc or a burned disc, it will not soften the picture. You will sometimes see stuttering/skipping/freezing or an unrecognized disc if the player has difficulty with a disc, but it will ABSOLUTELY NOT soften the picture.

I completely agree. A DIGITAL source copied will always be exactly the same, regardless of media used. Where not talking about analogue unlike VHS which will degrade after each copy made.

ARE you ALL idiots?

Do you have a CLUE what a DVD player DOES..and how it works?

Boy I feel stupid,I better put my helmet on and get on the short bus.

DVD 'players' do not FULLY read the information on a DVDr (they have in built error correction) so they only display (at the TV end) the info THEY can read from any given media..hence the 'softness'

If the DVD player do not fully read from the disc, you will see pixilation (square blocks) or jitter NOT softness.............

There was a thread recently that discussed audio differences in post shrink disks. Basically, people were finding measureable differences in the DB level of AC3 audio after shrinking, in some cases up to 20db lower than the original. Given that shrink does not transcode the audio, media was the only logical explaination at the time.

Of course, the simple way to test is to do an ISO read/write with decrypter and compare the two outputs.

[steve2713]

Again not possible. It doesn't touch the audio as you say, and the DVD player just reads the audio data as 1s and 0s.

A dvd player will not just read ones and zeros. It should actually soften the image so the tvs internal sharpening will display the image correctly. Also some dvd players are better than others and some have 12 bit Digital to analog conberters as apposed to 10 bit dacs. As far as the original post goes I am not sure about.

That's all well and good, but completely unrelated to a comparison between a pressed disc and exact copy, burned disc. A dvd player doesn't care what it's playing. It's not as if it's going to look at a burned disc and say 'hey, I'm going to soften the picture more, you're a BURNED disc!'

[RMaddog]

A 1 is always a 1, a 0 is always a 0. If a DVD player can't read a 1 or 0 the there error correction kicks in and guesses if it's a 1 or 0. Most of the time it's correct, sometimes it's wrong thus the block pixel.

Error correction can not and will not soften the image. A DVD only sees pits, or not pits 1 or 0 that's it, there is no way it knows if it's a pressed disc or a burned one.

[FulciLives]

If I recall there was a thread a while back where a certain version of DVDShrink appeard to give altered "soft" image output even when compression was set to none.

As far as I know there was only like one or two buggy versions that did that. I don't think the current version has this issue.

[Noahtuck]

I don't remember that thread and in NO WAY am i arguing with it... or FulciLives But i actually have the last 7 versions of DVD Shrink, 3.1.9.0, 3.2.2.0, 3.2.3.0, 3.5.1.0, 3.5.2.0, 3.5.3.0, 3.5.4.0, backed up and i don't remember any visual "soft"ning to my BU's, but then again... even in front of my 54" my eyes are not what they used to be

[steve2713]

Noahtuck, are you from the future?

My computer must be REALLY slow or something, the newest version I've had is 3.2.0.15 I feel cheated to know that you've got 3.5.4.0 (of course I'm guessing you're thinking of DVD Decrypter).

DAMN!!!!!!!!!!!!!!!
yep.... i was soooooo thinking the wrong program
Actualy i was thinking the right program i was just in the worng folder and spacing

But i still never noticed any diff. in the video "soft"ning
And i have the last 3 version's of DVD Shrink backed up/saved...

I have so many version's of sooo many programs going back for a loooong time plus the... ummm.... well....
