Bulk Rename Utility

Hello
i have been reading the manuel but not sure to understand it or not sure it is possible at all.
what i would like to do:
When taking picture with one of my cameras the file name is allways more or less silly
as example what i have
iiNIKON D300-DSC_4478.jpg
and what i want
iiD300_04478.jpg
i do imagine to have a batchfile *.cmd file which i do copy in the new directory.
The script will sort RAW and Movie file into other folder (so far this works fine)
then BRC should do the rename of the file!

any help how and where to start?
and it is possible to add some IPTC Information into the file like the copyright of the fotographe?

thanks for your feedback
have a nice day
vincent

Going by your one example, the below batchline works:
brc32 /pattern:*NIKON*.jpg /regexp:"(.+?)NIKON (.+?)-DSC(_)(.*):\1\2\30\4 /execute"
Currently, brc32 doesnt handle IPTC data
