Create an ISO of an UHD Bluray on Linux

[hhmkv]

Hello everyone,

I'm a newbie in the field of ripping Blurays and UHD Blurays but I'm on master level in ripping computer games.

However, I just would like to know, what is the best method for ripping Blurays and especially UHDs to an ISO image on Linux?

I bought the MakeMKV license and also a UHD friendly drive recently, but I'm not sure how to successfully create an ISO image of the disk?

I did it with dd after opening the disk with MakeMKV:

Code: Select all

sudo dd if=/dev/sr0 of=bluray.iso bs=4M status=progress

In one case with a UHD it worked well, but unfortunately not in the other case with a normal Bluray. I was able to use the UHD disk ISO in different ways (playing the film when mounted or ripping it with MakeMKV to an MKV file), but the bluray disk did not work very well.

I got a message from MakeMKV that opening the disk failed, and so ripping took endless time. It seems the disk was dumped including the copy protection or something else.

MakeMKV is not made for creating ISO images. The only thing I found out is the backup function in MakeMKV, which puts all files in a folder including a folder named MAKEMKV. So I would have to create an ISO from these?

So the question is how to to it the best way?

Thank you very much for your help

Hi.

I don't make .iso files of my ripped Blurays (I only have standard Blurays). I've only tried once, but I used imgbrun with Wine, and it worked fine.

Then extract the entire unencrypted disk to a folder, then use imgburn. Read more here: viewtopic.php?f=8&t=38708&p=178977&hili ... rn#p178977

Create a folder backup with MakeMKV first. You can then create an image (.iso) file from the folder structure. Unfortunately, "Nero 4 for Linux" seems to be the only Linux program that supports creating UDF 2.50 filesystems, which is required for Blu-ray discs. It's an old program from 2009 but still works. I have used both Nero and ImgBurn with Wine successfully, but I prefer Nero because it's a native program, it's made by a trusted German company and it includes a GUI and a CLI program.

Nero 4 is freeware since 2012. Download links can be found on this German website: https://alexhaack.de/20435902/nero-linux-4.html.

Run the GUI program "nero" first and enter the Serial number:

Code: Select all

9M1K-0098-P3HL-PK6P-T6UA-1E5X-E557-8X41

Afterwards, you can use the GUI or the CLI program "nerocmd". If you use the GUI, you need to chose the following settings to create a UDF 2.50 image:

You can also use the following CLI command:

Code: Select all

nerocmd --write --drive=-1,0 --bd --udf --udf-revision=2.50 --udf-partition-type=physical --data "backup_folder/*"

"nerocmd" skips all empty folder, though (I haven't found a way to change this). For example, it will not include an empty "CERTIFICATE" folder. I don't know if this could be a problem for some Blu-ray players. Use the GUI if you want to include empty folders in your image.

Thank you very much for your replies.

I'm using the iso method, because it's easier for me to handle the files instead of many small files in a folder.

However when I use makemkv the backup function is greyed out. Is this function not working for all disks or setups.

This should be the right command for the command line

makemkvcon backup --decrypt disc:0 /path/to/destination --progress

Oh yes, I remember this tool nero, I also had a licence for this years ago. And the linux version was published in 2005, as far as I remember, so 20 years ago.
I installed it from the source and it works perfectly, also detects my bluray burner drive.

But it seems it was created not with large bluray discs in mind. So even when I use image writer it says the filesize of my files is too large to burn. I'm only able to change between BD25 and BD50. Not BDXL or custom size possible. My backup size would be 60,5 GiB (64.991.335.218), settings are Bluray with custom udf version 2.50.

Do I need the command line in those cases?

Thank you very much for your help

Hello,
I make a lot of BluRay discs from various documents I own because of the size of them. This is what I use :

Code: Select all

 mkisofs -udf -iso-level "3" -input-charset "utf-8" -V <Name of Disc>  -allow-limited-size -o  <Name Of ISO File>.iso   <Directory containing the data to put into the bluray>
 

Hope this helps.

The backup button is only available if the disc isn't opened. Run makemkv and then click the backup button without opening the disc.

Unfortunately, I don't have experience with such large images. Perhaps Nero doesn't work with them. I can create 50 GB images with Nero's image recorder, regardless of whether "BD" or "BD DL" is selected. If your version is from 2005, I would try the latest version from the download link above.

Do I need the command line in those cases?

Try it with "nerocmd" and please report back if it worked.

This won't create an image compliant with Blu-ray specifications, so it won't be possible to burn it back to a Blu-ray disc and play it on a hardware Blu-ray player. I guess it will work with software players like VLC, though.
