FFmpeg File Size Optimizer

A tool designed to help you send videos through communication apps with maximum quality while meeting specific file size constraints. Recently upgraded to allow custom codec selection and tolerance levels.

How It Works

The script performs initial calculations based on the video's bitrate. If the resulting file size doesn't fit within the specified tolerance, it iterates through further optimizations to ensure the highest quality while meeting your desired file size constraints.

Usage

Building the Tool

Clone the Repository and Enter the Directory

git clone https://github.com/Nexenek/ffmpegfilesizeoptimalizer.git
cd ffmpegfilesizeoptimalizer

Build It

cargo build --release

Or Download from Releases

Running the Script

The script requires ffmpeg and takes five required arguments:

• input_file - Path to the input file
• output_file - Path to the output file
• target_size_mb - Target file size in Megabytes (accepts floating-point numbers)
• tolerance - Maximum allowed difference between the output file size and the target file size (accepts floating-point numbers)
• codec - Define your own codec to optimize ffmpeg for your machine. Defaults to libx264
• hwaccel - Hardware acceleration to use. Defaults to auto

./ffmpegfilesizeoptimalizer input_file output_file target_size_mb tolerance codec hwaccel
