makelive 0.1.0

Add the necessary metadata to photo + video pair so Photos recognizes them as Live Photos when imported

MakeLive

Convert an photo + video pair into a Live Photo.

This is a simple command line tool that will apply the necessary metadata to a photo + video pair so that when they are imported into the Apple Photos, they will be treated as a Live Photo.

Usage

makelive photo.jpg video.mov

Requirements

• macOS (Tested on 13.5.1; should work on 10.15+)
• Python 3.9+

Installation

• pip install flit
• flit install

API

from makelive import make_live_photo

photo_path = "test.jpg"
video_path = "test.mov"
asset_id = make_live_photo(photo_path, video_path)
print(f"Wrote Asset ID: {asset_id} to {photo_path} and {video_path}")

Note: XMP metadata in the QuickTime movie file is not preserved by this function which may result in metadata loss.

Metadata including EXIF, IPTC, and XMP are preserved in the image file but will be rewritten and the Core Graphics API may change the order of the metadata and normalize the values. For example, the tag XMP:TagsList will be rewritten as XMP:Subject and the value will be normalized to a list of title case strings.

If you must preserve the original metadata completely, it is recommended to make a copy of the metadata using a tool like exiftool before calling this function and then restore the metadata after calling this function. (But take care not to delete the ContentIdentifier metadata.)

How it works

In order for Photos to treat a photo + video pair as a Live Photo, the video file must contain a Content Identifier metadata tag set to a UUID. The associated photo must contain a Content Identifier metadata tag set to the same UUID. Unfortunately, these tags cannot be written with the standard exiftool utility if they do not already exist in the file as the metadata is stored in Maker Notes which exiftool cannot create.

This tool uses the Core Graphics and AV Foundation frameworks to modify the metadata of the photo and video files.

Caution

This tool has not yet been extensively tested. It is recommended that you make a backup of your photo and video files before using this tool as it will overwrite the files.
