Patches ExifTool has already been patched in. Then you can get the names you want to copy to and from and use the commands that Phil listed above. Impact Arbitrary code execution can occur when running exiftool against files with hostile metadata payloads. You can use the appropriate command below to install ExifTool with your system’s package manager. That will list all time metadata in the file. ExifTool is a command like program which can get and change video metadata. But today, we’re going to focus on ExifTool a cross-platform Perl library plus a command-line application for reading, writing, and editing meta information in various files ( various image formats, audio formats, video formats. FILE is one or more source file names, directory names, or '-' for the standard input. ExifTool There are a lot of web apps and browser addons that you can use to strip out metadata from photos. Since you're looking for just time stamp data, I'd suggest further refining the command from FAQ 2 to this: Description A command-line interface to Image::ExifTool, used for reading and writing meta information in image, audio and video files. I have all the outputs saved if you need more info: ExifTool ExifTool Version Number : 10. So in the last case, if the file has a video stream, an English audio stream, a German audio steam, an English subtitle steam, and a German subtitle stream, you have Track1 through Track5, each with the MediaModifyDate/ TrackModifyDate data. The date/time tags are as follows: 1) recent video where the CreateDate and Playmemories Date Taken are the same without and then with quicktimeutc and 2) an older converted video. That value could be taken from the OS system timestamp ( FileModifyDate), the XMP modify timestamp ( XMP:ModifyDate), the modify date in the Quicktime header ( Quicktime:ModifyDate), or from the MediaModifyDate or TrackModifyDate from one of the video/audio/other streams in the file, of which every track in the file has. To copy or move metadata, the -tagsFromFile feature. Just about every program interprets the metadata in slightly different ways and often gives it names different from what exiftool does. To write or delete metadata, tag values are assigned using the -TAGVALUE syntax, or the -geotag option. Additionally, we don't know where that program is grabbing the information from, as there can be multiple places it can read to get the data. ExifTool extracts standard meta information and a variety of audio, video and image parameters, as well as proprietary information written by many camera models. We don't know what program you're using to get the "date modified", "media created", and "date created" values. The QuickTime format is used for many different types of audio, video and image files (most notably, MOV/MP4 videos and HEIC/CR3 images). So my question is: how can I write GPS coordinate tags to video files in a way that Apple/Microsoft photos apps recognize the location.To expand a bit further. 2) When writing only pseudo System tags (eg. However, there are three cases where file write permission is also required: 1) When using the -overwriteoriginalinplace option. I am guessing that this is the underlying cause for the problem, and that a tag with the '1.1' ID is needed, but this is a bit beyond my knowledge. In general, ExifTool may be used to write metadata to read-only files provided that the user has write permission in the directory. or the audio/video data in WAV/AVI files to search for additional metadata. If I strip the tags first and then write the tag fresh, I get only the tag with the xyz ID. See Image::ExifTool::TagNames for documentation on available tag names. When I check the tag IDs, I find that the original Apple embedded tag has '1.1' as the ID, while the tag written by ExifTool has '(copyright symbol)xyz' as the tag ID. After some more digging, I noticed that writing coordinates to a video with existing coordinates results in two QuickTime:GPSCoordinates tags. After updating a file with new coordinates in this way, I found that both the Apple and Windows photos apps no longer recognize the GPS location of the video file. Another side effect is that the two tags (or metadata) for 'Media Data Size' and 'Media Data Offset' are moved toward the bottom of the metadata output from an 'exiftool' metadata. containing 51 deg 23' 51.08" N, 5 deg 59' 7.44" E, 29.756 m Above Sea LevelĪs a test case, I am using a file straight from my iPhone XR. The result is that a new tag is created that is just 'Track', and that has the newly assigned value of 'Mono (AAC)', and the original 'Track 3 Name' tag is unchanged. $exifTool->SetNewValue('QuickTime:GPSCoordinates', $GPSCoordinates) # With GPSCoordinates e.g. Code Select Expand my $exifTool = new Image::ExifTool
