  • For batch converting ISOs to a specific resolution and format while preserving folder hierarchy on Linux, you can indeed use ffmpeg with a bash script. However, you might also consider using HandBrakeCLI, which is a command-line interface for HandBrake, a popular video transcoder.

    Here’s how you could use HandBrakeCLI to achieve your goal:

    1. Install HandBrakeCLI if you haven’t already:
    sudo apt-get install handbrake-cli
    
    1. Write a bash script to iterate through your directories, converting ISO files:
    #!/bin/bash
    
    # Set input and output directories
    input_dir="/path/to/your/input/directory"
    output_dir="/path/to/your/output/directory"
    
    # Convert ISOs to 720p h.265
    find "$input_dir" -name "*.iso" -type f | while read -r file; do
        output_file="${file%.iso}.mp4"
        handbrakecli --input "$file" --output "$output_dir/$output_file" --preset="Super HQ 720p30 Surround"
    done
    

    Adjust the preset according to your needs. You can check available presets with HandBrakeCLI --preset-list.

    1. Make the script executable:
    chmod +x convert_iso.sh
    
    1. Run the script:
    ./convert_iso.sh
    

    This script will convert all ISO files in the specified input directory to 720p h.265 MP4 files using HandBrakeCLI while preserving the folder hierarchy.
