DVD ripping: does DVDFab give the best picture quality?

[Tom80112]

I have been ripping my DVD library to ISO for playback
via a WD-TV for the convenience of instant movie selection.

After ripping about 200 movies with Anydvd and CloneDVD2, I
noticed that the picture quality was not quite as sharp as
the original DVD. I downloaded the most recent DVDFAB 30 day
trial software and I'll be darned if it doesn't make sharper
looking movie copies (ISOs) of DVDs.

I am not using compression but I am ripping just the main movie
and AC5.1 track to save space. I thought that since I was NOT
compressing the movie to fit a 4.7GB DVD+R that the video copy
would be the same no matter what software I used. Not so..

Has anyone else found that DVDFAB makes better quality copies
than CloneDVD2?

Is there an "all-in-one" program that makes even better quality
copies than DVDFAB?

Thanks
Tom

For best quality: I use dvdfabhddecrypter to rip "movie only" then transcode with DVDShrink - unless the compression is tighter than 75% or so - then I use DVDRebuilder and encode. If you want a menu - use the "customize" mode. Also, after ripping, I play the dvd rip with media player classic (open the .ifo file) and test playback before shrinking.

No compression means NO COMPRESSION. If you are seeing a difference
from one program's uncompressed "rip" to another program's uncompressed "rip"
then it is all in your head.

Thanks for being a jerk heck54. You must also believe that all CD Players sound the same.

Hech54 is right, no compression means no compression, there should absolutely be no difference. If you're seeing a difference between the two then maybe you should check the settings in CloneDVD2, there's probably some compression going on.

I do not use Clonedvd2, but would have to agree that there must be a setting that is giving unsatisfactory results. If there is a question about the quality of the ISO, try using ImgBurn as the ISO maker in conjunction with AnyDVD. ImgBurn does not have any compression utility involved nor does AnyDVD, so the resulting ISO should be identical to the original DVD image quality.

[Tom80112]

Obviously any difference I am seeing is not a factor of compression. Since I am not using any.
In both cases I select DVD9 as an output size. Something else is going on during the processing
of the DVD to an ISO.

I noticed that DVDFab makes the ISO copy in about 14 mins while CloneDVD2 makes the same
ISO copy in 7-8 mins. I wonder if CloneDVD2 is triggering some error correction by reading
the DVD faster?

As an example, if you rip a song with nero you may not get as good a rip as if you ripped
it with EAC. EAC is slower but it is exact while nero might be approximating when error
correction occurs..

The differences I see are not visible on a PC screen but when blown up on a 50" Kuro, the pictures
look different with DVDFab looking better.

[thymej]

Interesting, there should not be a difference.

Do this, get MediaInfo and paste the info here from the first VOb file from each of the rips, the good one and the bad one.

Also, describe what you are seeing that is different.

[Noahtuck]

Compared to what ? the original pressed dvd9 ?
And you are comparing the original and the copy on the same tv ?
Or the copy looks better on the 50" compared to the original on the PC screen ?

I noticed that DVDFab makes the ISO copy in about 14 mins while CloneDVD2 makes the same
ISO copy in 7-8 mins. I wonder if CloneDVD2 is triggering some error correction by reading

Or are you comparing 2 different "rips" ?

[Tom80112]

As stated clearly. My comparisons were of ISO rips using DVDFab and also using CloneDVD2.
The ISO rips were played on a Pioneer Kuro 50" using a WD-TV to play the ISO over HDMI to the
Kuro. I was camparing the DVDFab ISO rip to the CloneDVD2 rip.

I will stop posting now since my original finding only seems to attract negative comments. It's
a waste of time for me to post when people just want to say it isn't so without exploring ideas
of why it might be. These same people probably wouldn't see a difference between Visio Plasmas
and Pioneer elite Plasmas.

The way I see it, people are trying to help you out. Everyone so far has told you that there should be no difference between the two rips IF no compression was used, that's the truth. Clearly somethings up with your settings. Unless you give more details on the settings used it's kind of hard to help you.

You might want to post in the Slysoft forums, makers of CloneDVD, maybe they can help you over there.

You can get access to the VOB files in the iso files by using 7zip, etc. 7zip can open ISO files as if there were zip files. Just extract the first VOB of each iso and post the MediaINFO info for each vob.

My first thoughts on a possibility cause is one of the rips changed the header info in the vob files or something. Maybe the mediainfo info can help. Maybe wrong frame rate header info in one and not the other, maybe one of the rips causes the player on the 50" to chose to do the wrong kind of deinterlacing, also may there is a probem with the way CloneDVD remuxed the video to create the ISO, etc, and so on.

Hopefully the MediaINFO can shed same light, if you post again that is.

Tom 80112,
You asked help, you' re making them "exist", and for thanks you have "Oh....you are gonna have a FUN time here..." as an answer.
Do NOT stop !
People can see ...!!!
Cheers.

There's a difference between ripping an audio CD and ripping a DVD. I am no expert (hopefully someone else will better explain this), but it has something to do with differences in error correction and data blocks/sectors, etc. on dvd and audio cd. Because of that here is no need for an 'EAC' type secure ripper for DVDs.

You are right to question why there is a difference when using clonedvd2 and dvdfab (both w/ no compression). Everyone else is also right saying there should be no difference. I've only used dvdfab (free) and dvddecrypter. Maybe, just maybe, there's a setting somewhere that was accidentally set/ticked?

Anyway, just thought it'd be helpful to point out the differences in ripping.

Hope things get figured out


BTW, that Kuro must be awesome. Wish I had one.

Clip a few seconds form each rip - the same few seconds - and post them so we can compare the two. If you are attempting a side by side comparison it could be as simple as an overlay issue. However there are tools that will let you objectively compare two copies of the same video. Having clips to play with would help.

[hech54]

It's a waste of time for me to post when people just want to say it isn't so without exploring ideas of why it might be.

Because it's all in your head like EVERYONE (including people like me who have been at this game since 2001) has told you. This site used to be called VCDHelp(before DVD burners were available or affordable). Many of us have been here watching fantastic ripping tools come and go since the early days of DVDDecrypter and DVDShrink but one thing hasn't changed.....an uncompressed DVD rip is an uncompressed DVD rip and someone who swears he hears a difference between a CD ripped with EAC and a CD ripped with CDex or even Nero(which most people here DONT recommend for video work) is gonna change that.

[thymej]

Comments like "...it's all in your head..." is the reason why Tom 80112 said he will not be posting anymore. So instead of making comments like that, make it a challenge to find out why he sees a difference. It does not matter if you think it is all in his head. There are real reasons out there that really can cause a bad rip. The ripping tool has a bug in it that makes bad muxes of the video and audio, maybe the pulldown flag got droped, maybe it got added, just a bad rip, who knows, etc.

If Tom 80112 is still reading this thread the following info will help those who want to help, as requested be other already:

MediaInfo info from the bad and good rip (Thymej)
Clips (same clips) from the bad and good rips (guns1inger)

Use 7zip or another zip program that can open ISO files like zip files to access the VOB to get the above info.

And last but not least, ignore the users that make unhelpful comments.

[stiltman]

I think the OP needs to compare apples to apples first
AnyDVD is a ripper, CloneDVD is a transcoder/encoder
DVDFabDecryptor is a ripper, DVDFab (full) is a ripper and transcoder/encoder

First rip the DVD
Running anyDVD, rip to iso (don't use cloneDVD, use anyDVD only)
Running DVDFabDecryptor, rip to iso (don't use the full version use the free version that just a ripper)
Or rip both to files and let imgburn create the iso

Now compare the 2 file size to file size
Are they they same or within a few KB for the main title?
If so, compare the 2 on your TV
Do they look the same?

We don't just THINK it's all in his head.....it IS all in his head. Get that straight.
A "bad rip" is one that cannot be played back on a computer player.

[victoriabears]

Surely not all rippers are the same, and one may rip a better quality, uncompressed, than another?
Also dvd players do present things in different qualities and one thing I have seen lately , is that a heavily compressed dvd, when played on an upconverting player could get some of the lost quality back?

Do remember we all have different quality thresholds and different eyes and ears, it is impossible to create a benchmark that we would all agree on. You should do what makes you happy and watch the quality of the content more than the quality of the technology.

[hech54]

It's data.

[jimdagys]

DVDFab can be used to rip a DVD directly to an AVI, just like Fair Use Wizard (see screenshot).
In this case there is conversion from one format to another.

I agree 1000%....but then that is "user error" territory...

[wtsinnc]

With the caveats of standard definition DVDs and television, I cannot see any image quality or player compatability difference among backups ripped using DVD Shrink, DVDFab HD Decrypter, AnyDVD/CloneDVD2, 1clickdvdcopy/DVD43, or DVD Decrypter using the same media and burner.

[Philgo]

Just joined to learn a bit about this stuff.

Perhaps perhaps Tom has something to do with DVDfab and he is pushing it.
