How to rename my files - Advanced

[angels15]

Hi
I am using a trial version of Photo Mechanic 6 on a new iMac using OS 10.14.6 (Mojave)

I am reviewing Photoshop as a potential replacement for MediaPro. I already have a standard method for naming my new image files which uses the Capture Date (where available) plus some text and part of the original file name ie YYMMDD_hhmmXXX1234.
I understand how to use the date components to achieve the first part of this ie
{iptcyear2}{iptcmonth0}{iptcday}_XXX
but I am not clear how I can delete various characters within the original filename when I add {filenamebase}

Please explain the following:
1) how do I simply delete the first four characters in an image filename such as IMG_1234 ?
2) how do I do this at the end of a string - and how can I do a find and replace within the software ?

Can I also do the above within the Save As or Ingest dialogue ?
Thank you for your help

Instead of deleting, if all you want is the 1234, how about using the {frame4} variable instead?  (It will evaluate to '1234' in your example.)

2) how do I do this at the end of a string

While there exists a fancy variable substring extraction, I think this will suffice:

{iptcyear2}{iptcmonth0}{iptcday}_{frame4}

and how can I do a find and replace within the software ?

Sure.  You can choose a naming in both of those dialogs.

HTH,

Thanks for this - and clearly I meant Photo Mechanic not Photoshop above !
