Videos in a directory can be renamed using a standard format of choice. We might begin the filename with a four digit year, two digit month, two digit day, an underscore and then hour, minutes and seconds, another underscore, and then either a sequential count starting at 00 or some text describing the contents, similar yo a standard naming for photos in Section 67.6.
An egrep regular expression for this is
A directory of videos that contain meta data can be easily renamed
using the exiftool command. Our example here first
-testname to report on the renaming but will not do it.
Once the renaming plan is confirmed, replace
exiftool -d %Y%m%d_%H%M%S_%%.2c.%%le "-testname<CreateDate" -ext mp4 *.mp4
If the proposed changes are correct then do the actual renaming by
adding a verbose option
-v and changing
exiftool -v -d %Y%m%d_%H%M%S_%%.2c.%%le "-filename<CreateDate" -ext mp4 *.mp4
