Exiftool recipes
As discussed in #310 and #309, we'd like to add an Exiftool section to ffmprovisr, but we need recipes! Please share small scripts here!
exiftool -j input - json output
exiftool -X input rdf output
exiftool -v# input where # is a number between 0 and 5 levels of verbosity, 0 being simple, 5 being trace level.
Getting a specific value, such as ImageWidth:
$ exiftool -s3 -Imagewidth out.jpg
320
The -s3 gives you the value only, which i need sometimes. Using -s1 or -s2 gives element names as well.
using
$ exiftool -s out.jpg
Will display the element names that you can use with this option for a particular file.
These are really simple and obvious but they're the only ones I really use at work.

A good start. I think it's more about practical use and not knowing what is actually possible to do with a tool.
I know that you guys are into preservation, but I use it to scrub all metadata from my images when sharing:
exiftool -all= image.ext
To work on images in recursive subfolders:
exiftool -r -ext jpg -all= foldername
Rename files to datetime stored in exif tag:
exiftool '-FileName<DateTimeOriginal' -d "%Y-%m-%d_%H.%M.%S%%-c.%%e" .
The output filename will be appended with -x where x is a counter number if multiple files have the same timestamp, i.e. multi burst camera photos.
Staying with timestamps, set to specific one supplied for all files:
exiftool '-DateTimeOriginal=2018:03:28 12:00:00' .
When the date of my camera is wrong, I shift the timestamps of the images:
Add one hour exiftool "-AllDates+=0:0:0 1" .
Subtract one hour exiftool "-AllDates-=0:0:0 1" .
Format is Y:M:D h:m:s
Please note that everything is from memory and notes as I am not at work now, so please double check before publishing.
Just remembered, find files with missing exif timestamp in folders:
exiftool -filename -r -if '(not $datetimeoriginal)' folderpath/
You can probably tell that I have a thing about times!
@kieranjol Like I just did to Andrew... Could I possibly task you with writing a summary/introduction to sox and why people might find it useful? But I understand if you don't have the time! (Unlike @privatezero 😜)
Do you mean exiftool?I know nothing about sox!
