[Script] MKV to MP4 - All audio / Subtitles

[bisol]

Hello All,

I am a newbie with ripping / Hanbrake and now. I have a huge collection of Dvds (more 500) and I want to rip them all.

The goal is this :
- An input string to set if it is a movie or an episode (tv - anime) : OK
- Audio & subtitles : with french / english / japanese (lot of animes) : Only if the choice is episode : OK
- if audio 2.0 only : encode with coreaudio aac 2.0 : OK
- if audio 5.1 is available : encore without mixdown (I want true 5.1) : OK

Last modification :
- Added 2 passes with turbo mode
- Choix of movie or anime (high quality or normal)
- Added check foreign subtitles

Code

Code: Select all

Thanks by advance for your reply.

You can parse the output of a scan to see what audio / subtitle tracks exist, then run the encode with the appropriate numbers.

The syntax for multiple tracks is 1,2,3...

I have modified the script. I didn't choose the cleanest way to detect 5.1 but this is working for 5-10 movies so, I hope this is good.

Warning : The parameters are from the OSX version of Hanbrake (x264 advanced options & more). So, there is a difference with the normal preset found here (https://trac.handbrake.fr/wiki/BuiltInPresets) and the normal preset in the OSX version.

Edit : Added the AUDIO_TYPE_CH for the 1.0 channel

Script is now finished. I've added scan for foreing languages, params in variable, ...

You can also have a look at my script: viewtopic.php?f=10&t=26163

[bisol]

I have ! Your script is very good but if I've understand, there is a difference.

If the audio is not 5.1, I wan't to mixdown it (stereo / audio) to have small files.

But I repeat, you did a very very good job with your script. Mine is more adapted for my situation.

[AlBundy]

THe default setting is to copy the audio-stream, you can set --audio-mixdown to mixdown all tracks to Dolby Pro Logic II.
And of course you can define your own decoder settings.

Al

[bisol]

OK. Mixdown is not correct because I want Passtru if it's 5.1.
So, does it possible to do ?
- if 5.1 : passthru
- if not : mixdown mono / stereo (detect if 1.0 or 2.0 or 2.1...)

I know, thi sis not logical but I do not have so much space on my hdd to copy all audio...

[AlBundy]

the convert-settings in my script are global.

Are you sure, that you'll save much space with your settings?

Al

[bisol]

I have more than 1000 mkv so, if I can save 20mb for some files, I will be happy lol.

I've tried with a 45 min esisode with 2 languages audio and subtitles.

Copy audio : 480-490mo
Mixdown mono : 450mo

[AlBundy]

Ok, now I understand.
It seems that using your own script ist the best option for you.

Al

[AlBundy]

I've added an argument to my script to define own mixdown-mappings
here's an example:
hb.rb --input ~/test.mkv --output ~/test.m4v --audio-mixdown --audio-mixdown-mappings "5.1:copy,1.0:mono,2.0:stereo,Dolby Surround:copy"

[bisol]

Great news !

I make some tests...

[AlBundy]

I've uploaded a new archive.
The new syntax is
hb.rb --input /dev/rdisk1 --output "~/Desktop/Output_#pos#.m4v" --audio-mixdown "5.1:copy,1.0:mono,2.0:stereo,Dolby Surround:copy"

5.1, Dolby Surround etc. are regular expressions - if the description of an audio-track matches the regex the track will be mixed down.

The correct and maybe more common syntax would be something like this: --audio-mixdown ".*5[.]1.*:copy,.*1[.]0.*:mono,.*2[.]0.*:stereo"
but the example is more readabe and works well....

[bisol]

You did a very good job. I use your script now.

Thanks!
