[quote]i'm looking for a way to get my mp4 files renamed:
20150705_113713000_iOS.mp4
to
2015-07-05 11.37.13.mp4 format[/quote]
That part can be done using the Rename (Advanced) dialog in Regular Expressions mode.
Old name: (20\d\d)(\d\d)(\d\d)_(\d\d)(\d\d)(\d\d)\d*_iOS(\.[^.]*)
New name: \1-\2-\3 \4.\5.\6\7
For setting the modified timestamp based on the date/time in the filename, file name to modified date/time? has a script which does that. It will need a slight change for the different date format.
The line with:
re.Pattern = "^(\d\d\d\d-\d\d-\d\d)_(\d\d)(\d\d)(\d\d)(\.[^.]+)$"
Needs the _ changing to a space and the .'s adding between the time part:
re.Pattern = "^(\d\d\d\d-\d\d-\d\d) (\d\d)\.(\d\d)\.(\d\d)(\.[^.]+)$"
It would then work with filenames like 2015-07-05 11.37.13.mp4 (slight changes would be needed for other formats).
