high quality VOB files

[nji899jus]

I hope the following has been already answer but I wasn't able to formulate proper sentence to search for.
Here is the thing. I bought a DVD from Hollywood video/Blockbuster and I see it the movie was shrunk to fit a DVD-R.
Now I use a program and took the main VOB files and make them in HQ. I replace the original files with these new ones which were more than 4.
I used IfoEdit to re-make the ifo file but playing the video doesn't follow the original sequence. The player stoops at half the movie.
I edit the section:"VTS_PGCITI/VTS_PGC_1" and it did better but not quite.

Is this possible (adding the new VOB to the original movie directory, etc as explained?

[guns1inger]

Is it possible to take the original VOBs, re-encode them, and put them back ?

yes.

Can you do it using your method ? Not enough information to really say.

What software did you use to rip the original disc ?
What software did you use to re-encode the videos ?

Why not simply rip the disc and use DVD Rebuilder to re-encode it to fit a single layer disc, or better yet, burn to a DL DVD and keep the original quality ?

I bought a DVD from Hollywood video/Blockbuster and I see it the movie was shrunk to fit a DVD-R.

I doubt it was shrunk from the original retail DVD size as that would make it a bootleg which that place wouldn't carry. If you're saying it was originally a DVD5, then that's not unusual.

Now I use a program and took the main VOB files and make them in HQ.

I doubt that also. Are you saying you improved on the source DVD? I don't think so.

I replace the original files with these new ones which were more than 4.

That's not how it's done. You don't move in the new VOBs to replace the originals.

I used IfoEdit to re-make the ifo file but playing the video doesn't follow the original sequence. The player stoops at half the movie.

And now you know why.

Is this possible (adding the new VOB to the original movie directory, etc as explained?

Yes, it's possible, but no, not as explained. And since I really don't think that what you made is better than the original, I don't really see the point, either.

Edit after reading guns1inger's response: Oh, so you think he took a DVD9 and shrunk it to DVD5? That would make more sense. I didn't read it that way originally, but your version makes more sense.

[lordsmurf]

I see "United States" as the location, but I wonder if that's software-translated English? Not trying to be an ass, but the OP doesn't make much sense to me either.

Came to help, but can't. Tried. 8)

No....you didn't.

[jagabo]

You will not improve the quality of the video by re-encoding at a higher bitrate. The damage has already been done.

Take a sheet of smooth shiny aluminum foil. Squeeze it down to a ball that's 1 inch in diameter (DVD 5). Unfold it. It's now full of wrinkles (MPEG artifacts). Squeeze it down a second time but this time to a ball that's 2 inches in diameter (DVD9). Unfold it again. Does it have more wrinkles or less?

[nji899jus]

To all the guys who reply thank you:

The blockbuster video is as you say a DVD5 agree. There are 4 VOB files SIZE 3=1048404 1=515590.

I joined these 4 files into one using VideReDo (total size doesn't change).

I use MyDVD and make a video with this file. MyDVD produces 6 "HQ" files and I can see the picture is better. 5=1048404, 1=380648.

Using IfoEdit open VTS_O1_0.IFO click on Get VtS sectors, it does some fixing and then manually I adjust the time.

When I play it back "the menu, root menu" all these are there and I can navigate as it I was using the original, but the player (any player) plays only has the movie.

P.S These movie has 12 chapters. If I play chapter by chapter all play well.

I hope this information can aid so you can still tell me no it can't be done or do the following!!!!!!!!!!!!!!!!!!

[filmboss80]

Read and re-read the posts from jagabo and others. You will not get any better quality than the unmolested video from the source. MyDVD will re-encode. It is likely your imagination if you think the picture is better.

All the steps you took, and all those tools you used, were absolutely unnecessary.

I did not know that Hollywood Video and Blockbuster were one and the same. I never saw either store release a movie that was shrunk and put on a DVD-R.

Interesting...

[hech54]

TI use MyDVD and make a video with this file. MyDVD produces 6 "HQ" files and I can see the picture is better. 5=1048404, 1=380648.

You are as dumb as a box of rocks.

..............I did not know that Hollywood Video and Blockbuster were one and the same. .............

A 15 minute trip thru Google land says that the two companies are independant of each other. Will continue later when I have time.

[manono]

Oh, so my 'guess' about this was correct after all (pretty much). First, get rid of this MyDVD. Any program that only provides a quality indicator and doesn't allow you to set the bitrate and other encoder settings isn't worth the hard drive space it takes up. Second, no matter what you think, the MyDVD result is not better than the source. Third, if it makes DVDs, then didn't it also give you back IFO files and BUP files along with the VOB files?

If so, open the original retail DVD in VobBlanker, highlight the movie so it appears in the lower screen. Highlight it in the lower screen and hit the 'Replace' button to the right. Point to your new DVD. Give it an output folder and process. That way you not only replace the original DVD properly, but you also get back the menus and anything else that might have been in the original retail DVD.

If it didn't give you IFOs and BUPs, that's just another reason not to use this MyDVD. It didn't give you a DVD. A bunch of VOBs does not a DVD make.

[nji899jus]

Guys whoever came with insults should not bother to reply. You either reply with an intelligible answer or ignore me.
I know Blockbuster and Hollywood Video and BestBuy, etc, etc are different companies. They do sell DVD's than have been previously watched (except for BestBuy) and the total size of the movie fits in a DVD-R or DVD+R making a DVD5 as someone said.

My eyes don't fool me and the quality is better, who ever said so, you need glasses.

There is one person (manono[thanks]) who has really giving an answer but saying I can use VobBlanker which I will try.

MyDVD creates the usual *.ifo files but they were no use to me since I wanted to preserve the layout of the original movie e.g clickable menus, like PLAY, CHAPTERS, ETC.

The following has not much to do with my query but if I use my DVD recorder and then record a movie from TV in LP that produces 4 VOB files then using MyDVD PLUS and make a new "movie so to speak" makes 10 files in HQ.
Opening the first VOB file for both original and the new one and playing them side by side the picture is much better. And this goes for every movie.

[guns1inger]

Not trying to insult you, but what you say simply cannot be. You cannot take the content of a DVD, re-encode it to the same size using a tool like MyDVD, and get better quality.

If the original DVD was particularly bad (old VHS footage, for example) and you were skilled at avisynth or virtualdub then you might be able to improve the image quality and therefore get a better result.

But simple taking a lossy compressed studio movie and re-encoding it using a lossy compression can at best give you the same quality, and in most cases, reduce the quality. This is a simple fact.

[nji899jus]

We disagree in the quality of what you call re-encode but if the original file was recorded in SP or LP and then I use MyDVD which it is not a very great program but when I use this file and make a a new movie (in HQ) certainly I can see the difference.

I could send you this program so you can try except for the fact that I am not in the business of sharing commercial programs.

[johns0]

I gotta say you are alone in the universe when you say the quality is better when you re-encode,if you sharpen the picture when you encode maybe that tricks your eyes into seeing a miracle.

I'm just saying this so other newcomers wont be fooled into unneeded re-encoding.

[nji899jus]

I do not readjust the color or the tint or the contrast or the brightness and I have done this for many years.

Will leave it at that so that new people can have their own experiences.

I hope that VobBlamker does what I want to do and I will not argue if the quality will be the same or better as I said, as long as the end is accomplished.

thank you guys for your participation and help.

[jagabo]

I could send you this program so you can try except for the fact that I am not in the business of sharing commercial programs.

Why don't you upload a few short before and after segments that show the difference. You can use a program like DgIndex to mark small sections and export them.

[hech54]

.... I will not argue if the quality will be the same or better

But we will....EVERYONE will argue that the quality is NOT better.
You alone can magically re-encode standard def footage to your own version
of high def footage? Nobody else can? Everyone else in the world is wrong except you?

You have now graduated to a soaking wet "Box of Rocks".


Garbage In, Garbage Out or sometimes called Crap In, Crap Out is a computer term describing the fact that the output data is only as good as the input data. It means basicly the same as a video term, the output video and audio quality can only be as good as the source video and audio quality.

[filmboss80]

I suspect the OP's monitor or TV probably oversharpens the image, and after re-encoding, the softer recompressed image is perceived to look better, despite the marked degrading of the image quality. A slight bit of blurring and softening...

The only other possible explanation would be complete self-deception -- a sort of visual placebo effect.

Manono's advice on VobBlanker is a good one. It does not re-encode the video.

And associated noise reduction.

[nji899jus]

This evening I will upload 2 files. So late me tell you I use Mplayer to open the 2 pieces side by side at almost exavtly same scene.
Many people will not notice the "enhance color that much but it is there."
I don't change any setting and both files are played at the same time in the same computer, same lightning conditions, etg. I think you get the picture.

P.S I you ever watched the KungFu series at one point the main character (Kwai Chang) can't hear the cricket on the grass. I don't remember exactly the script, but the point is that some people can hear very faint sounds but for other these sounds don't exist.
Ditto for color.

That's not a valid comparison, because only 1 media player can use the overlay renderer at a time.

Switch the order in which you open the videos (e.g. 2nd video first), and you will see that the color/luminance will change

[jagabo]

Exactly. Only one program at a time can use the graphics card's video overlay feature. The other ends up using the same GDI path as other programs running on the desktop. Video overlay has its own brightness, contrast, hue, and saturation settings. Unless both are calibrated to look the same they will look very different. Video overlay may also include other features like deblocking, noise reduction, IVTC, different scaling algorithms, etc.

I was going to stay out of this thread since the first OP before any replies because it seemed so ridiculous (boy did i call that one!) but this reminded me of something i watched on TV.

They were showing how ridiculous people are that push totally naturally grown food without pesticides & genetic manipulation, ect.

Everyone said how much better it was for you, how it looked better, tasted better, ect.

But when given a blind test most of the time people chose the non naturally grown food.

Then when the EXACT same food, such as a banana, was cut in half, they would actually choose one half over the other saying it looked & TASTED MUCH better!!
LMAO!!


EDIT:
I remember now, it was Penn & Teller's BS - Organic Food.

[nji899jus]

I didn't realized that what you see when you play 2 videos at the same time, things changed, as explained. And I think that ends the whole enchilada.


P.S I thought this forum had people who are experts in "video" issues not "jokers" or "whip(pers)".

Nevertheless thank you to all you guys who participated in this case.

[greymalkin]

there's one joker in this thread and he thinks he can take compressed video and improve it by recompressing it.

Cheap shot ..........

[nji899jus]

Does the joker care to elaborate? or we take it really as a"joke".

[hech54]

In other words....you were wrong.

[nji899jus]

hech54 for your and the rest of the guys yes I was wrong.
