exiftool to manage DJI media files

DJI Drones don’t seem to remember the image count between formats of a media card. This creates a problem for me when I’m trying to backup and maintain my images and video.

Because the dates are all correct in the media files, retrieved from GPS data, organizing the files by naming them based on the date works for me.

Using ExifTool by Phil Harvey is a great solution for pulling the metadata from the files and renaming the files.

The command line that I was initially using is:

exiftool "-FileName<${CreateDate}.$filetype" -d %Y%m%d-%H%M%S%%-c -ext mp4 -ext dng -ext jpg dji*

It’s problem is that it orphans the SRT subtitle files from my videos that I’d like to keep matching the video files.

I’ve tried this variation to do it in one step but it doesn’t work, because the SRT files get renamed as MP4 files.

exiftool -verbose "-FileName<${CreateDate}" -d %Y%m%d-%H%M%S%%-c.%%le -ext mp4 -ext dng -ext jpg dji* -srcfile %f.srt

If anyone has a suggestion for how to rename all the media files in one directory I’d appreciate it. Even running two commands in sequence would be fine.

Update:

I’ve figured out that running these two commands in sequence will get me the results I am looking for:

exiftool "-FileName<${CreateDate}" -d %Y%m%d-%H%M%S%%-c.srt -ext mp4 -srcfile %f.srt dji*
exiftool "-FileName<${CreateDate}" -d %Y%m%d-%H%M%S%%-c.%%le -ext mp4 -ext dng -ext jpg dji*

I’m still looking for a way of doing it in a single command that may leave less room for error, but this is working for now.
