makemkvcon mkv -- title IDs confused with internal index IDs

[jvanns]

Hi. It seems that when I specify a title id, makemkvcon either considers it it's own internal index or it re-writes title ids depending on it's selection criteria (e.g. titles < 5mins are dropped and the title ids change).

Could someone confirm this independently? My example is a disc with 8 titles on and if I specify titles 3-8 inclusive, makemkvcon actually copies (or tries to) the titles with an *index* of 3-7 as output by the 'makemkvcon info' command - despite that same command also identifying the correct title IDs.

A simpler example is actually where I specify title 2 which makemkvcon info recognises as having a length of 3 hours yet when I supply 2 as the title ID to copy ala 'mkv' sub-command it actually rips index 2 which has a length of 30 minutes.

This happens with more than 1 disc from different, independent TV show box sets from different broadcast companies.

.... or am I going bat-shit crazy!?

I can confirm that <title id> does not correspond to the listed Title #number. It appears that the <title id> is related to titles added that meet the minimum length specified,
such as --minlength=1600 in this example. So from the example below Title #5 becomes <title id> 0 and Title #12 becomes <title id> 1

Title #3 has length of 26 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #4 has length of 14 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #5 was added (12 cell(s), 0:32:45)
Title #6 has length of 694 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #7 has length of 319 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #8 has length of 267 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #9 has length of 324 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #10 has length of 359 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #12 was added (22 cell(s), 1:36:01)
Title #14 has length of 779 seconds which is less than minimum title length of 1600 seconds and was therefore skipped
Title #15 has length of 179 seconds which is less than minimum title length of 1600 seconds and was therefore skipped

This pretty much makes using a <title id> worthless. You can never predict which title will be selected. Very frustrating.
If anyone can offer commands to make it possible to select the correct Title # I would like to see it.

I supply 2 as the title ID to copy ala 'mkv' sub-command it actually rips index 2

Do you mean it's an off-by-1 error? If instead of '2' you use '3' do you get the correct result?

You can never predict which title will be selected.

Is there no way to parse for the string "added" before hand? If not, you could start the process then send SIGINT. Clearly that's dirty, but should work. Could you equally rip based on playlist.mpls?

Just to elaborate what I am doing. I'm on Windows working with a DOS Batch file. I want to find the Main Title and rip it. I don't know how to do that with makemkvcon64. So I use Handbrake cli and scan the ISO to a file. I parse the scanned file to find the Main Title index number. I tried using the index number with makemkvcon64 but the result is not what I expected. After much trial and error with title length I realized that makemkvcon64 only considers the titles added and counts them starting from 0. I tried setting a title length of 0 hoping all titles would be added. Then my desired index number minus 1 would match makemkvcon64 id number. That failed because any title that has 0 length is not added and creates an error.
Since my last post I decided to work with the Main Title length, parse the Handbrake scan for the Main Title length and use it with makemkvcon64. That seems to work but I am finding that the title lengths between the handbrake scan and makemkvcon64 differ. So I am subtracting 20 seconds from Handbrake's Main Title length. Now the Main Title gets added first by makemkvcon64 and I use title id 0 to rip the desired title.
This is a lot of gymnastics. There may be a more straight forward way but I have not found any complete documentation for makemkvcon. If there is a document site or Wiki for makemkvcon please let me know.

Can you post this scanned file here in a codebox?

I am new to this forum. How do I post a file in a codebox?

Highlight to text you wish to appear in a "codebox" & then select the '</>' (5th from left) icon above the editor window.

You post the code inside a pair of [code][/code] tags, as in:

Below is the output from a Handbrake ISO scan using a " --min-duration 1800" (30 minutes).
Using makemkvcon64 "--minlength=1800" Title #5 becomes <title id> 0 and Title #12 becomes <title id> 1.
If I use makemkvcon64 "--minlength=5,751" (20 seconds less than Feature length 1:36:11) Title #12 becomes <title id> 0.
Parsing the scanned file tells me the Main Feature is Title index 12 with a 5771 second duration.

To rip the Main Feature of this ISO I use this command:
makemkvcon64 --minlength=5,751 mkv iso:"Z:\Movie ISOs\THE_BOXTROLLS.ISO" 0 "G:\MakeMkv\THE_BOXTROLLS"

HandBrake has exited.

First, is there not a file/playlist that marks the main title? Do you really have to comb for the longest timestamp?

Anyways, to verify match the handbrake output of...

Code: Select all

  + Main Feature
  + index 12

... to the output of makemkvcon's.

Code: Select all

Title #12 was added (22 cell(s), 1:36:01)

Since you have it working, I'm now kind of confused on what you want to do :-/. I will say though that makemkvcon has inconsistencies. Here is the usage: https://www.makemkv.com/developers/usage.txt
Also read this thread as well, in particular the last post: viewtopic.php?f=17&t=31557&p=139088&hil ... on#p139088
Also, the "info" option prints more information with the -r switch, which isn't documented. It seems makemkvcon is explicitly programmed to output for the GUI's usage and not for independent usage.

Anyways, I'm guessing because I don't rip to mkv, but this should work...

Code: Select all

./makemkvcon mkv disc:0 $title_num $HOME/output/

... where $title_num is the problematic number :-/ (12? 0? 1?...?). I don't own a plain DVD anymore but I'll pick one up at thrift store and join in your pain for a little bit.

I tried your suggestion with this:

Code: Select all

"C:\Program Files (x86)\MakeMKV\makemkvcon64.exe" mkv disc:0 1 "G:\MakeMkv"

And I got this with no movie ripped:

Code: Select all

MakeMKV v1.17.5 win(x64-release) started
Using direct disc access mode
Title #1 was added (15 cell(s), 1:12:49)
Operation successfully completed

However this worked:

Code: Select all

"C:\Program Files (x86)\MakeMKV\makemkvcon64.exe" mkv disc:0 0 "G:\MakeMkv"

So using the Title #1 fails and you have to figure out the number of titles added and start counting from 0
