Repairing damaged DVD files with hex language

[dvdmaster1]

Hi guys !

I have an old DVD movie from 2005 and the DVD is very badly damaged. I managed to get all the information recovered before the disk broke completely.
So, I must to ask is it possible to get the DVD files to work properly with hex editor?

Thank you

Theoretically, possible. Practically, impossible.

But how you you define 'all the information recovered' ? Can you play the vob files ? If you can then you can simply author and burn a new dvd.

I can play the VOB files but they don't play correctly, I mean that the picture is pixelated and ambiguous I can show a few screenshots of the DVD when I get home

Is this a backup, retail or homemade? did you decrypt it if it's a retail version?

This is a homemade DVD, it's recorded by using the DVD recorder

If your data are corrupted you can try to use different decoder (it may behave better in terms of the error concealment and resilience) - using hex editor imply from perfect understanding video compression codec (it's syntax) but as pointed by DB83 it is humanly impossible to fix manually 4GB of data (or even manually, thoroughly inspect in hex editor).
Such manual fixing will be even more exhaustive than fixing every frame in Photoshop or comparable tool.
In short: If you don't have backup then your movie is lost... (but with different decoder errors may be less visible).

Search for such phrase: "error resilience and concealment in video coding" - if you are unable to fully understand knowledge described in those papers then your movie is lost.

In synopsis you have a recording from 2005 (on DVD-RW?) you find is degrading, you copied the files to harddrive and now find pixillation when you play back the Vobs?

Try using https://www.videohelp.com/software/DVD-Decrypter to recover as much information as possible.
DVD-RW are inherently unstable, so what has been lost maybe lost forever.

Edit: you haven't detailed what 'damage' is. Is it scratches or just degradation?

And that file what i'm trying to repair manually, is in size "418 862 kt".

It was asked, maybe indirectly, how you 'recovered' the data ie removed from the disk to your HDD.

To elaborate, did you simply attempt to copy the files from the disk through Windows or use a decrypter. While copying for a self-made disk would work, a decrypter does it sector by sector and can often get the data of the surface with scratches. Dvd-decrypter is very good for that.

Lots of methods. Too many to count.

I have a scratch like that, and I can't make even sector-by-sector copy of that disk because Windows cannot recognize it anymore

[transporterfan]

That doesn't look like a scratch to me. Looks more like a crack. If it is, then the data is lost on every point of the sectors the crack bisects.
DVD-Decrypter will rescue what it can...that is all you're going to get. If it is a scratch it looks deep. Same applies.
Doubt it will polish out.

That looks scratch for me

My optical drive makes a weird sounds when it tries to read the disc...

[transporterfan]

DVD discs can rotate @ 32000 rpm. Hopefully it is a scratch. If its a crack the disc can shatter and take your drive with it.
Your drive makes weird sounds because it recognizes the error section and tries to continuously re-read the bad sector areas.
DVD-Decryptor will stop on those areas and try and try, and try to get the data until it gives up.
It might play better on a DVD player because it would probably just try skipping them.

Edit: that's a max limit speed, can't remember the exact speed they rotate at during play, 4500 something like that.
Still enough to wreck a drive.

Even my DVD-player can't recognize the disc

Polish out the scratch, use DVD-Decrypter, or give up and throw it away. There is nothing else can be done. I'm done here. Sorry.

I fight with this DVD because I can't throw it away because of nostalgic memories

[transporterfan]

I understand that and I'm sorry for your loss. There are companies which specialize in this type of recovery http://www.filesaversdatarecovery.com/removable-media/cd-dvd-recovery.html but is beyond the ability of VideoHelp.

What about the hex editing in this situation ? Or is it completely impossible ?

[transporterfan]

If you can't get the scratch out, I imagine nothing will even read it. Even for a hex editor it has to be readable and without error, otherwise you'll just be duplicating the error.
A hex editor works by just reading data sequentially. Even if you got all the data into a file you would be unable to directly write it back to a dvd in a playable order. For want of a better description, it just creates a huge text document. Again, there are people who can do this, but like everything else, it will cost. This is a specialist recovery technique.

After Effects can do it, it's called de-rezzing. There are tutorials are on youtube.
