This is a tricky one.

I take pictures and videos with both an iPhone and a Sony camera and import them into the Photos.app in the Mac. I do a little cleanup, delete unwanted photos and then export the original JPG files to a folder (no conversion). Pictures are automatically renamed and sorted into subfolders using Hazel and a Exiftool script.

The pictures for both devices register the correct GMT offset for date and time and Exiftool renames then perfectly.

Videos are a different story. The iPhone register the correct GMT offset and videos are correctly renamed. The Sony camera theoretically does it right too and when I import into the Photos.app the time is correct (in my case GMT -3) when I look at the info pane. The Problem: When I export the original videos the metadata does not recognize the GMT offset, so the time of the videos are always 3 hours more than it should. It resets to GMT +0.

When I export the videos I don’t know which device took it unless I look at the metadata.

Is the a script to identify just the videos taken with the Sony Camera and correct the GMT offset?

  • \$\begingroup\$ Can you post your exiftool commands, the make and model of the Sony camera, and if possible, link to a short video from the camera? The fix might just be as simple as a check for the camera model and adding -api quicktimeutc to the command. \$\endgroup\$

  • \$\begingroup\$ Here are the specs and script: Camera model: Sony RX100 Mark I (1st gen) Exiftool command for movies: exiftool -d %Y-%m-%d_%H%M%S '-filename<${CreationDate;}.%e' "$1" Exiftool info of a movie taken with the camera, after the export from Photos.app. Look for “Creation Date” in the end of the log. The video was taken 18:12:05 but the info states 21:12:05. exiftool -a /Volumes/BUFFALO3/Sync/2016-12-27_211205.mov Creation Date : 2016:12:27 21:12:05 \$\endgroup\$

  • \$\begingroup\$ I've looked around and I can't find an unaltered sample video in order figure out the proper tag to differentiate between Sony RX 100 videos and other videos. If you can figure out a tag that's unique to the Sony videos, you can try this command for videos: exiftool -if '$TAG eq "VALUE"' -api quicktimeutc -execute -if '$TAG ne "VALUE"' -common_args -ext mp4 -ext mov -d %Y-%m-%d_%H%M%S '-filename<${CreationDate;}.%e' . You would have to replaces TAG with the name of the tag that is unique to Sony videos and VALUE with the value of that tag. \$\endgroup\$

  • \$\begingroup\$ I found this unique tag for the Sony camera videos. Description : AVCHD: /Volumes/RPBG_SD32/PRIVATE/AVCHD/BDMV I tried your script like this: exiftool -if '$Description eq "AVCHD: /Volumes/RPBG_SD32/PRIVATE/AVCHD/BDMV"' -api quicktimeutc -execute -if '$Description ne "AVCHD: /Volumes/RPBG_SD32/PRIVATE/AVCHD/BDMV"' -common_args -ext mp4 -ext mov -d %Y-%m-%d_%H%M%S '-filename<${CreationDate;}.%e' “$1” The script returns an error but renames the file with the same GMT +0, no correction. \$\endgroup\$

  • \$\begingroup\$ Based on your idea, I tried another script using the globaltimeshift option and it worked OK. exiftool -if '$Description eq "AVCHD: /Volumes/RPBG_SD32/PRIVATE/AVCHD/BDMV"' -globalTimeShift "-0:0:0 3:0:0" -d %Y-%m-%d_%H%M%S '-filename<${CreationDate;}.%e' "$1" Thanks StarGeek. \$\endgroup\$
