Set Creation Date from EXIF

Script: set_creation_date_from_exif.sh

A script that extracts the CreateDate EXIF tag from video files (supports .m4v and .M4V formats) and sets the file's creation date accordingly. It can process individual files or all files in the current directory.

Usage

The set_creation_date_from_exif.sh script was created after I realized that movies downloaded from iCloud have incorrect creation dates, making it difficult to import them into tools like Lightroom.

To use the set_creation_date_from_exif.sh script, follow these instructions:

1. Clone the Repository:

   git clone [email protected]:cccr/scripts.git
   cd scripts

2. Make the Script Executable:

   chmod +x set_creation_date_from_exif.sh

3. Run the Script:

   • To process all .m4v and .mov files in the current directory:

   ./set_creation_date_from_exif.sh .

   • To process a specific file:

   ./set_creation_date_from_exif.sh <filename>.m4v

4. Verify Metadata: After running the script, you can verify the metadata with the following command:

exiftool -a -G1 -s -n -api QuickTimeUTC=1 -FileCreateDate -FileModifyDate -CreateDate -GPSCoordinates -DateTimeOriginal -CreationDate . 

List of Acceptable Extensions

The script is designed to handle video files with the following extensions:

# List of acceptable extensions (case insensitive)
ACCEPTABLE_EXTENSIONS=("m4v" "mov")

This means the script will accept both lowercase and uppercase variations of these extensions, allowing for flexibility when processing files.

Requirements

ExifTool: This script requires ExifTool to extract EXIF metadata. You can install it via Homebrew:

brew install exiftool
