Add -overwrite_original option to suppress the creation of backup files. If you need to set the time to something different than what the filename is, then you would use this, adding the time zone if needed:Įxiftool '-CreateDate=2018:12:23 00:05:42' 20181223_000542.mp4 With the -api QuickTimeUTC option, exiftool will automatically adjust the time to UTC.

Mac Finder will also correctly adjust from UTC. This is because the CreateDate tag for MP4 files is supposed to be UTC and Windows properties will read it as such. If not, you will have to add the time zone like this:Įxiftool -api QuickTimeUTC '-CreateDate<$-04:00' 20181223_000542.mp4 This will work correctly as long as the video was taken in the same time zone as the computer you are currently using. In that case you can simply use this command (see exiftool FAQ #5)Įxiftool -api QuickTimeUTC '-CreateDate<$Filename' 20181223_000542.mp4 In the case of your example filename, the filename appears to have been named for the time it was taken i.e YearMonthDay_HourMinutesSeconds. Then you will want to use one of these commands. For those that use Chocolatey, the Chocolatey exiftool package will add exiftool to the PATH and is a well maintained package There is also Oliver Betz's Alternative Exiftool build for Windows which includes an installer and is a bit more security friendly. First you will probably want to rename the exiftool(-k).exe to just exiftool.exe and place it someplace in your PATH (see install exiftool-Windows).
