Footage from damaged Blu-ray

[koberulz]

From the look of the disc, the dye is completely gone from a small portion. Looks like a fingerprint at first glance. It's right on the edge, and MakeMKV got 95% of the way through, or thereabouts. But on hitting the bad spot, just quit out and deleted the MKV file.

Is there any way I can get the good part of the file off the disc?

try ISOBuster - https://www.videohelp.com/software/ISOBuster

$60 is a lot for something that might not even work...

Then you better do some research of your own ...

Then feel free to go ahead and spend nothing for something that doesn't work.

[johns0]

If it's precious files then $60 isn't a bad price,if it's something easy to replace then do that.

sorry but if the disc is transparent in that area of damage, the dye and all information written there is permanently gone. nothing can read what isn't there any longer.

If you re-read post #1, you'll find that the OP completely understands this. What he wants to do is recover the rest of the material on the disc. The problem he is trying to solve is that his software quits when it hits the bad spot, and then erases everything it read up until then. That's why ISOBuster was recommended: that is exactly what it was designed to do.

[aedipuss]

ok. there are free bit for bit copiers that offer the option to not delete broken files when they encounter them. i've used an old one called supercopier but don't know if it runs on anything newer than win7. there's an updated version call ultracopier, but i haven't tried it.

supercopier options

Unstoppable Copier or Imgburn can copy Discs that are damaged/incomplete.

[koberulz]

Yeah, it's a TV broadcast of a basketball game. Given how far MakeMKV gets before crashing I'm hoping the game itself is intact and it's just the post-game wrap-up that's affected.

As far as ISOBuster's price goes, it seems silly for trialware to not actually do the thing I need to trial. All it seems to be able to do is tell me there's a disc in the drive, and what folders that disc contains, which is information I can glean from Windows Explorer. Any time I try to extract anything it demands money.

I'm actually running Windows 7, so I'll look into supercopier.

ImgBurn failed with this disc as well.

I didn't have a damaged DVD or Blu-ray disc to try but I was able to use the latest version of ISOBuster's trial software to create an ISO disc image from a "good" recorded DVD. (I right-clicked on Track 01 in the left pane and selected Extract Track 01 followed by Extract User Data (*.ISO). Windows 10 could mount the ISO and display the files. (If you have Windows 7, there is free software available which will allow you to mount images.) It is possible to copy the files from a mounted image.

In the past, I was able to use the trial version of ISOBuster to output another type of disc image file, TAO. I was able to use TAO files to recover video from damaged or unfinalized DVDs recorded by my DVD recorders although it requires some effort. I couldn't find an option to extract the image as a TAO file in the latest trial version.

Did you try Roadkil Unstoppable Copier ? Or the other softwares mentioned in the articles linked in post #4 ?

[koberulz]

So I finally managed to rip it with ISOBuster, using dummy data where necessary, but the resulting ISO still won't rip with MakeMKV.

Can you mount the ISO and see any m2ts files in the BDMV folder's STREAM folder?

[koberulz]

Yes.

[usually_quiet]

Yes.

Some of those m2ts files might have game video. Can you copy the m2ts files to a different folder and play any of them?

[koberulz]

I can, and it mostly works. Not sure why MakeMKV is throwing an error. Is there another way to remux it as MKV and keep the chapter points etc?

MKVToolNixGUI (part of MKVToolNix) might be able to do this. (There is a portable version for 64-bit Windows, which I downloaded and unzipped.) However, I don't know what it will do when it encounters the bad parts of the video.

I ripped one of my commercial Blu-ray movies to files and folders and used it to test MKVToolNixGUI. I right-clicked MKVToolNixGUI's Source Files section and opened one of the many playlists from BDMV/Playlist. (You may only have one playlist because your disk is not a commercial movie.) MKVToolNixGUI asked to scan for more playlists, and after I agreed, added all of them to the Source Files Area.

I selected one playlist that looked like it was not a fake. Information created from the playlist appeared in MKVToolNixGUI's Tracks, Chapter, and Tags section. Next, I entered the destination file name and location for the MKV and clicked "Start Multiplexing". When the program completed the multiplex, I had a playable MKV with all the chapters, video, audio, and subtitle tracks.

If ISOBuster replaced the damaged portions with dummy data there shouldn't be any "bad" video for MKVToolNixGUI to trip on, should there?

If the dummy data can cause problems for MakeMKV, it can cause problems for other programs as well. Maybe it can cause MKVToolNixGUI's multiplexer to crash too. It has been a long time, but as I recall, when I tried playing a video file containing dummy data, the player crashed when it reached the dummy data.

[Edit]You'll need to try it to find out what happens.

[abolibibelot]

Perhaps remuxing the damaged m2ts files with TSMuxer would do the trick...

[koberulz]

Remuxing with Toolnix did the trick. As I hoped, the whole game is intact, the missing data isn't until the last minute or so of the broadcast, well into the post-game coverage.

Given abolibibelot's advice, I have to ask: Did you need to re-multiplex the m2ts file with TSMuxer or did MKVToolNixGUI do the job all by itself?

[koberulz]

Just toolnix.
