I have 158 folders, each containing 5-15 video files that are each a few minutes long. I would like to merge all of the videos into one video per folder, and delete the rest.
The folders are named as dates in a certain year with gaps between them (01.11
, 01.12
, 01.13
, 01.14
, 01.18
... 01.28
, 02.01
, etc.), and the files in them are named as follows:
ds_AAAAA_BB_CCC_480.mp4
The first blank (AAAAA
) is a number that is the same for all files in that folder. For folder 01.11
, the number is 03075
, and it goes up by one for each folder after that.
The second blank (BB
) is the order of the files, from 01 to however many files are in that folder.
The third blank (CCC
) is a set of three letters that varies per file and can be ignored.
For a couple examples, the first file in the first folder (01.11
) is ds_03075_01_nws_480.mp4
. The last (7th) file in the fourth folder (01.14
) is ds_03078_07_zen_480.mp4
.
Ideally, I'd like the new files to be in a separate folder (just to make it easy to delete the old files), and named in a format like 01_11.mp4
, 01_12.mp4
, and so on, but any naming convention there would be fine.
Does anyone have any suggestions as to how to go about this?
