Syntax for -api option

[Eric Haas]

Hi,

I have been using ExifTool for years to geotag photos.  Thanks.

I can do this on the MacOS (latest version) command line:

exiftool -v2 -geotag '/Volumes/Data\ RAID/5D/_GPS/*.gpx' -geosync=+8.5 '-geotime<${DateTimeOriginal}-06:00' /Volumes/Data\ RAID/5D/_Picstotag/

I would like to limit interpolation and extrapolation to 30 seconds.  I can do this via the .ExifTool_config file.  I understand there is also a way to do this via the -api option at the command line.  I can't figure out the syntax to do that.  Is this possible?  It would be ideal to have all my inputs as a single command.

Thanks,
Eric

See GeoMaxIntSecs and GeoMaxExtSecs just below it.

The -api option is used by listing the api you want to invoke and setting any value you need to set.

I believe the options you want to use would be
-api GeoMaxIntSecs=30 -api GeoMaxExtSecs=30

[Eric Haas]

exiftool -v2 -geotag -api GeoMaxIntSecs=30 -api GeoMaxExtSecs=30  '/Volumes/Data\ RAID/5D/_GPS/*.gpx' -geosync=+8.5 '-geotime<${DateTimeOriginal}-06:00' /Volumes/Data\ RAID/5D/_Picstotag/

Produces this output:

It appears that program is interpreting the -api option as a file name.  I'm not sure if I need to put the -api option in a different part of the overall input.

I have re-read FAQ #3 but it doesn't give me any other ideas to try.

I am tagging Canon .CR2 files.

The -geotag option requires that the next argument must be the name of the geotrack file.  Because you put -api as the next argument, it is interpreting that as the filename.

You can't split options that require a second argument. Put your -api options after the gps track name.

Okay, I understand now.  And yes, that works!  Thanks!
