MOV file not wiped of GPS data

[Songdog1]

I ran two MOV files through the command "exiftool -all= <filename> and the resulting files still contain the GPS data. JPGs run through the same command are scrubbed of GPS data.

I'm finding the GPS data using Quicktime Player inspector.

Exiftool cannot write most video tags, just read them.  I believe that the only thing it can write for MOV files is some XMP tags.

Thanks. I clearly had no idea.

Interestingly, after I edit the MOV file in FCP X and Export it to Compressor, if I take the resulting file and then run it through Exiftool, data gets scrubbed. It scrubs some data, namely authoring data. I'm not sure if the GPS data made it through FCP X to the final exported file and got scrubbed or if the GPS data never made it through the editing process. But it seems that Exiftool does write to MOV files. Or at least it is doing something...

The file support is all listed on the ExifTool home page.  As StarGeek says, ExifTool only has limited write support for MOV videos.  It only writes XMP plus a few native date/time tags.
