Clear all tags and other metadata

Help
1

When adding a new video to MKVToolNix, is it possible to automatically remove (clear) all metadata, such as language tags, file titles, chapters, track names, etc.?

Welcome!

No, there’s no functionality for doing this automatically.

OK, thx for the answer.

How does one do it manually? In one fell swoop?

Right now I have to go to each field and right-mouse click and then highlight swipe to delete each field separately. It’s tedious doing it that way.

Try this .

#!/bin/bash
FILE=${@}
echo "FILE: ${FILE}"
# Batch avi, mp4, m4v files.

if [[ $FILE =~ \.(avi|mp4|m4v)$ ]]; then
echo ${FILE}
ffmpeg -i ${FILE} -map_metadata -c:v copy -c:a copy ${FILE}"-out".m4v
#mkvpropedit "${FILE}" -d title
else
# Batch mkv files.

find -name '*.mkv' | while read FILE; do
echo $FILE
mkvpropedit "$FILE" -d title

#Optional batch rename to m4v, (Jellyfin) uncomment below.
# find -name '*.mkv' | mv $FILE ${FILE%.mkv}.mkv
done
fi

if you want to rename mp4, mkv. m4v or avi.. try this.

#!/bin/bash

#Dependences; mkvpropedit and exiftool
#removed; ffmpeg -i ${FILE} -map_metadata -c:v copy -c:a copy ${FILE}.m4v

# Function to strip metadata from MP4/AVI/M4V files
strip_metadata() {
    local file="$1"
    echo "Stripping metadata from: $file"
    
    # Create temporary file
    local temp="${file}.temp"
    
    # Process the file
    if exiftool -overwrite_original -All= "$file"; then
        #mv new_name="${file%.mp4}.m4v"
        # Replace original with the processed file
        echo "✓ Successfully processed: $file"
    else
        echo "✗ Failed to process: $file"
    fi
}

# Function to process MKV files
process_mkv() {
    local file="$1"
    echo "Processing MKV: $file"
    
    # Remove title metadata
    if mkvpropedit "$file" -d title; then
        # Create new filename
        local new_name="${file%.mkv}.m4v"
        # Rename file
        mv "$file" "$new_name"
        echo "✓ Renamed to: $new_name"
    else
        echo "✗ Failed to process: $file"
    fi
}

            echo "File not found: $file"
            continue
        fi
        
        # Get lowercase extension
        ext="${file##*.}"
        ext=$(echo "$ext" | tr '[:upper:]' '[:lower:]')
        
        case "$ext" in
            mp4|avi|m4v)
                strip_metadata "$file"

                process_mkv "$file"
                ;;
            *)
                echo "Unsupported file type: $file"
                ;;
        esac
    done
else
    echo "No files specified, processing all video files in current directory..."
