Title: ExifTool on Mac
Post by: suninmoon on April 13, 2023, 02:43:16 PM

Hey all

A while back I posted this question about changing the date of a video file and you helped me immensely

https://exiftool.org/forum/index.php?topic=13937.0

I'm using a Mac now and need to do the same thing. I'm not as familiar with the terminal in Mac as I am with command prompt in Windows so I'm a bit lost. Will this command you originally game me work in macOS terminal?

exiftool -api QuickTimeUTC=1 -QuickTime:CreateDate='2022:01:01 12:00:00' movie.mp4

I did try in terminal but got back a cryptic

Code Select

joshua@Joshuas-Mac-mini Desktop % exiftool -api QuickTimeUTC=1 -QuickTime:CreateDate='2013:01:02 18:04:2'6 test.mp4

The file was on the desktop where I thought I was running the command. Can someone tell me what I did wrong?

Thanks
Josh

Generally the difference is single and double quotes are switched but it looks like you have a typo in the date/time with the quote before the 6

prompt in Terminal is a sure-fire sign you have a misplaced single quote in your original command. Typing ctrl+c will get you out of it.

I should have caught that, my apologies. Yes the command worked perfect after I corrected that typo.

I got advice on here about adding GPS as well so I'm assuming that it's only the single quotes that should be different from Windows. I'll give that a shot and let you know.

Thanks!

Double or single quotes should work on the Mac except when there is a dollar sign in the command. That requires single quotes around it.

But IMO, it's a good habit to just use single quotes on Mac/Linux.

Thank you. Single quotes worked ok on the GPS command.I just wish I could find a way use text expansion in the terminal app. Using cut and paste gets tedious :)

You can put your ExifTool options in a text file and use the -@ option to read this file rather than entering everything on the command line.
