updated: 9/7/2022: Hi folks,
I apologize it doesn't quite work as I intended. When I ran the batch script below, I tested on 14 DVD ISOs, from a (the same) series, in the same folder and it worked perfectly. I ran a quick test on ISOs in folders - it seemed to work. Later, I found that it didn't really work in ISOs in different folders as I had intended. Further testing this morning of different DVD series/movies ISOs in the same folder didn't reliably export to mkv all the time either. Some it failed, had to run twice, some it didn't do at all for various reasons (like "No additional sense information" errors). I wanted to delete the below post, but then, maybe if someone saw it, it might help you to get to that next level where I failed. I won't have time to work on it for a while, but if I do, will update when/if I succeed. Thanks and good luck.
First, it failed if there are spaces in the iso folder or file name. So you have to use single quoting in the 'for' variable - I played with it last night and at least got that working (code not updated below for that), but even when I was able to capture and quote the full path/filename with spaces/special characters, makemkvcon64.exe didn't always read the ISO and skipped it.
Second problem... If it does happen to work on your ISO and your are exporting to the same folder, what happens if you have a same generic title filename export to the same folder where a previous one already exists - it will ask you if you want to overwrite it. You could use 'echo "y" | [commands-set]' but then it would overwrite older titles you already wrote. I was working on 2 ideas. 1) get folder path of iso and take the last folder in the file/folderpath (i.e. E:\videos\iso\abc and 123\abc123.iso) take "abc and 123" and make that the folder export - so using the code below, mkdir E:\videos\abc and 123\ and then export the mkv to E:\videos\abc and 123\abc123.mkv - basically creating a folder for each mkv iso export so you don't run into the overwrite issue. 2) the other idea I had was appending date/time to the mkv export - for example, abc123.iso would become abc123_202209072207.mkv or something like that, but I could not find a way to dictate export filename to makemkvcon64. After the makemkvcon64 mkv command, I could probably do some kind of do/while loop, looking for mkv files without the date append in my export folder, append date/time to filename, then continue on the with the next title/next ISO.
Hopefully others will have better luck than I did.
sorry again.
==----------------------------
So was reading through this and here's what I needed:
I needed to take a bunch of ISO images with multiple titles in each DVD, export them to MKV (which I will mess with later to compress them, move to mp4, etc)... I got the makemkv, installed it (too lazy to create a path for it, so I copied the installation files in C:\Program Files (x86)\MakeMKV\ to the folder where I was working (in this case, H:)...
I then created this batch file:
Code: Select all
@echo off
for /f "tokens=*" %%A in ('dir /B /S *.iso') DO (
makemkvcon64.exe info %%A > title.txt
FOR /F "tokens=2 USEBACKQ" %%F IN (`findstr /C:"Title " title.txt`) DO (
REM echo %%F
makemkvcon64.exe mkv %%A %%F E:\Video
)
)
SO WHAT???
So, what this does is:
1) find each iso file from the folder I run the batch file in - look in subfolders too (dir /B /S *.iso) and assign each path/file to %%A.
2) use makemkvcon64 to get info from each file %%A, and output that info output to a file called "title.txt"
info will output a bunch of stuff, but two items interested me - first, "Title #xx" where xx=number of title, but these title references are useless for me for what I need to do as they also include titles that makemkv will ignore. Next, the info outputs info like this:
"Title 1
Title 2
Title 3"
...etc
That's the one I need - those are the real titles that are eligible for export.
3) Take the second word (or number in this case, tokens=2) from searching Title.txt for "Title " <-- this is important, must have double space after Title to avoid pulling the titles from Title #xx that aren't necessarily usable.
REM echo %%F is for debugging - checking the value through each loop to see that it's actually getting "xx" where xx is the correct and exportable to mkv title number.
4) use makemkvcon64 mkv [filepath\filename] [title # as a integer] E:\Video <-- E:\video is my output folder.
Done. Hope this helps someone be able to batch process MKVs from iso files.
