============================================================  
Addendum-1  
If someone does not need to split the 'camel cased' textual part and does not need to delimit the words by a space character, then the formatting action using the $regexp expression can be removed.  
The formatting action for tag-field 'P0' can be removed too.  
Also the upcasing can be taken into the formatting action.  
Also %P1% and %P4% can be replaced by %DUMMY%.  
So the reduced action group will look like the following ...

============================================================  
Addendum-2  
The reduced problem as described in Addendum-1 can also be solved by the converter "Filename - Filename".

 

**Convert** | **Filename - Filename** | **ALT+3**

 

_Select format string_

 

Old filename pattern:  
**%1\_%2\_%3\_%4\_%5**

 

New filename pattern:  
**$caps2(%5) - %2-%3**

============================================================  
Addendum-3  
The complete problem including 'camel case splitting' can also be solved by the converter "Filename - Filename".

 

**Convert** | **Filename - Filename** | **ALT+3**

 

_Select format string_

 

Old filename pattern:  
**%1\_%2\_%3\_%4\_%5**

 

New filename pattern:  
**$regexp($caps2(%5),'(?\<!^)(\u\l|(?\<=\l)[\u\d])',' $1') - %2-%3**

 

Preview  
**Learning Web - 01-01.mp3**

 

============================================================  
Note:  
Due to the converter "Filename - Filename" Mp3tag does not need to work physically on tag-fields within the files.  
This might drastically reduce the processing time to a minimum.  
Especially when processing large files such as MP4 files.
