I just got into usenet and some of the files downloaded are ISOs. I’m trying to figure out the best way to convert them to mp4s so that I can play them through plex. I’m running on a headless arch server (Manjaro), and I’d prefer to keep the conversion there if possible.

Anyone have experience with this?

I was so confused because all my isos are of operating systems

[–] [email protected] 17 points 1 year ago (2 children)

I know you're joking, but actually most ISOs I have are actually operating systems or games. I've never seen a normal movie release as an ISO, except maybe 1:1 copies of retail disks.

Radarr seems to love finding blu-ray quality movies as ISOs

[–] [email protected] 5 points 1 year ago

Add ISO to the extension blacklist in SAB so that the download fails and Radarr tries a different one.

If they are backups, rather name them .img.

Handbrake reads and converts DVD movie and video ISOs. If they are encrypted, MakMKV and DVDDecrypter can be used to get them ready for Handbrake.

[–] [email protected] 2 points 1 year ago

I think this is the best response for OP!

[–] [email protected] 2 points 1 year ago (1 children)

I've tried HandBrakeCLI and for some reason it detects all tracks as 5 seconds and outputs a 2.4mb file from a 29gb ISO. Does this mean they're encrypted?

[–] [email protected] 3 points 1 year ago (1 children)

If it's a 29GB ISO it's definitely not a DVD but likely a BluRay. It may be encrypted/corrupted/not a video. Try MakeMKV next to see if it can decrypt and recognize the chapters.

[–] [email protected] 3 points 1 year ago (2 children)

Does MakeMKV have a command line tool for Linux? I’m trying to do this all through ssh

[–] [email protected] 4 points 1 year ago (2 children)

I believe they do. Their Linux installer link is buried in the forums: https://forum.makemkv.com/forum/viewtopic.php?f=3&t=224

They have batch ISO convert CLI for Windows: https://forum.makemkv.com/forum/viewtopic.php?f=10&t=15426

You may need to network share your headless seedbox or whatever you have the ISO on to do this off a linux or Windows machine.

[–] [email protected] 4 points 1 year ago (1 children)

Turns out makemkv is on AUR so I was able to yay -S makemkv and one of the options was the CLI! After this I was able to run makemkvcon mkv iso:<file> all <dir> and it seems to be working! Thank you so much for your help

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago) (1 children)

I'm glad I could help! Can you post the CLI command syntax that worked for you to run makemkv to decrypt your ISO? It will help others are trying to figure this out in the future. Or was it just the single makemkvcon command you posted?

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago) (1 children)

Oh, I did in my comment. It was just:

makemkvcon mkv iso:my_file_name.iso all outputDirectory

Note: outputDirectory must exist, it could even just be ./

makemkv will then scan the iso for its chapters, filter out the small ones, convert the large ones to mkv files and output them in your directory you provided. Then I just looked for the biggest one and deleted the smaller ones, the big one ended up being almost the same size as the ISO and was indeed the movie output I was looking for.

[–] [email protected] 1 points 1 year ago (1 children)

Thanks for following up! I'm surprised it just dumped out one mkv file without you having to command a specific chapter to decrypt. It's good to know that you can probably set up a batch file to decrypt everything in a whole directory!

[–] [email protected] 2 points 1 year ago

Well the all parameter had it convert all the ones big enough, I ended up with 3 then just paired it down to the one I cared about.

[–] [email protected] 2 points 1 year ago

Thank you kind sailor!

[–] [email protected] 3 points 1 year ago

Here are makemkvcon syntax parameters for you to try: https://bluray.beandog.org/makemkv/man/makemkvcon.html

Handbrake is able to "mount" ISOs, should be pretty straightforward from there.

Always mount unknown ISO files you download off music websites.

[–] [email protected] 7 points 1 year ago
[–] [email protected] 6 points 1 year ago

ISOs are disc images. You’d have to mount them with something like Daemon Tools. To be honest, it’s been awhile since I pirated anything but movies, so there’s probably a better way to do it now. ISOs are also what we use in emulation when the console in question used discs, so I have a bunch of ISOs of discs I backed up to use in emu.

[–] [email protected] 6 points 1 year ago (1 children)

Can you mount them? If so what does that look like?

[–] [email protected] 3 points 1 year ago (1 children)

If you are in windows, right click on the iso and the option to mount the image should come up. Once mounted it should look like a DVD or CD was inserted and should behave as such.

[–] [email protected] 3 points 1 year ago (1 children)
[–] [email protected] 1 points 1 year ago

Should be similar on most Linux distros.

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago) (1 children)

If there is no encryption involved, you should be able to unpack them with 7zip without any mounting and then convert with ffmpeg to a format of your liking. IIRC, DVDs usually consist of a bunch of VOB files. You can just cat them all together and then send directly to ffmpeg.

[–] [email protected] 1 points 1 year ago (2 children)

Cating them together does only work in some cases though.

My god yes. The download speeds are so fast and I have never had issues with quality while using it. No more waiting 3 weeks to download a movie with 1 seeder.

If you have any questions, I can answer to the best of my ability.

It seems pretty nice so far. I was in a few private trackers for movies and TV and they were fine but I stopped using them when my VPN apparently failed me and I got called out by my ISP, so I’m really digging not having to worry about seeding. Also, some private trackers have a weird amount of drama and it’s kind of off-putting.

I still use MAM though, it’s by far the best tracker around and I love the community and books it provides.

Any, part of the improvements I’m seeing I think is just because I’m finally using radarr and sonarr, I think you can technically use these with torrents too, so this quality of life improvement could probably have been achieved without Usenet. But not having to worry about seeding is very nice.

[–] [email protected] 4 points 1 year ago

I've always used Free ver. of PowerISO to "mount" the disc image to a virtual drive like others mentioned. Anyone who's emulated PlayStation 1/2 games would be very familiar with this format. Otherwise any old software released on CD format you'll probably find as an ISO.

[–] [email protected] 4 points 1 year ago

Use ffmpeg to convert them

[–] [email protected] 3 points 1 year ago

I would imagine if they are ISOs a DVD converter would probably work.

[–] [email protected] 2 points 8 months ago

I’d like to recommend you some freeware like handbrake and makemkv. But if you DVDs are copy protected, you’ll need to try some other free tools like Free DVD Decrypter and dvdfab hd decrypter.

[–] [email protected] 2 points 1 year ago (1 children)

Assuming the .iso file is a DVD/Bluray image: Open the file in MakeMKV. Select the tracks you want, and it will…make a MKV file out of it. That should be fine for Plex.

[–] [email protected] 1 points 1 year ago (2 children)

I'm doing this through a terminal, no GUI tools

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

eac3to to demux video and audio, mkvtoolnix or mkvmerge to remux to mkv. edit: You need to extract the dirs from the iso first though, you can use something like 7-zip for that though.

[–] [email protected] 2 points 1 year ago

@Cqrd i use wincdemu to mount and 7zip to unzip contents without mounting on windows boxes, same for Linux but wincdemu is cdemu, fuseiso, acetoneiso or brasero

Mount them and move stuff over.

[–] [email protected] 1 points 1 year ago (1 children)

Handbrake can convert DVD images into other formats if that's what you have. (7ish gigs each)

[–] [email protected] 1 points 1 year ago (1 children)

I've tried HandBrake and for some reason it detects all tracks as 5 seconds and outputs a 2.4mb file from a 29gb ISO

[–] [email protected] 2 points 1 year ago

Try messing around with feature selection, or try with "--main-feature".
