Renaming chapters in an mp4 from a text file

[RandmTask]

Hi

I have an mp4 that is already in Chapters and I want to rename all the chapters from a text file (or by copying and pasting in)

The text file would only have the names in it (No times etc as the file already has chapters) ie :
The Raise
Probability
Testing
...

Is there any program that will let me rename the chapters by a text file? I tried Subler and MetaZ but they only seem to allow me to rename one at a time and Subler crashed when I tried to drag in a txt file. MKVtoolnix I couldnt work out if it supports it or not

Thanks

No. There are tools that let you rename chapters but no renaming by a random text file formatted in a random way.

Thanks for your dismissiveness.

It's hardly random.

The chapters already exist and I want to rename them with a text file. I don't need to construct new chapters hence no need to have timestamps etc.

No. There are tools that let you rename chapters but no renaming by a random text file formatted in a random way.

What tools (GUI or commandline) would you recommend to rename titles of chapters in mkv and mp4 ?

It's hardly random.

The randomness is not given from your point of view, but it is from the point of view from the application that should do the matching.
Usually tools only allow to import chapters from given files and not do automatic renaming of existing files.

-> No tool I know of has an option to load a file with new chapter names and automatically overwrite existing chapter names based on that.
Could such features be written: sure
Do I suspect that this will happen: no, because this is not a frequently requested option and probably not worth the effort to implement this for a single user.
So my guess is the easiest way to get to your goal would be to:
a. extract the chapter info from your source (most tools allow importing and exporting of chapter information)
b. adjust the chapter information based on your text file (this needs to be done manually or by a script; should be easy with php or python or other scripting languages and a bit more fiddling with bash scripting)
c. import the newly adjusted chapter file in the tool you use to replace the existing chapters
alternatively:
convince someone to adjust his tool that this is a feature worth implementing.

What tools (GUI or commandline) would you recommend to rename titles of chapters in mkv and mp4 ?

I'm biased there since I'm the author of Hybrid and thus would use Hybrid since I'm used to it.
In Hybrid I would:

• Start Hybrid
• Load the source
• Set "Base->Processing->Video" to "passthrough"
• Set "Base->Processing->Audio" to "passthrough (all)"
• Switch to the chapter tab, edit the names.
• Set a new output name, create a job and start the job processing.

But I would not recommend Hybrid since it's way to overpowered (and huge) for the task at hand.


For mkv files I would recommend https://www.videohelp.com/software/chapterEditor since it is more suited for the task.
For mp4 files I would recommend https://github.com/stevie910/drax or YAMB

It seems chapterEditor can import chapter names from a txt file but only for mkv (uses mkvtoolnix)

Simply editing chapter names in mkv can be done in mkvtoolnix GUI. Uses mkvpropedit to edit mkv in place (no remuxing required).
