MP4Split is a lightweight and efficient shell script utility designed to split MP4 video files into smaller segments of a specified size, ensuring the integrity and synchronization of audio and video streams. Utilizing the power of FFmpeg, MP4Split automatically handles keyframe adjustments and segment numbering, providing a hassle-free solution for managing large video files.

The initial use case for developing MP4Split was to facilitate the storage of video files larger than 4GB on FAT32 storage systems, which impose a file size limit. The script is designed with a focus on maintaining perfect audio and video synchronization, addressing common challenges encountered when splitting and storing large video files.

• Segmentation: Splits MP4 video files into smaller chunks based on user-defined size.
• Synchronization: Maintains audio-video synchronization and integrity through automatic keyframe adjustments.
• Numbering: Generates sequentially numbered segments, with an option to start numbering from any value.
• Powered by FFmpeg: Offers high compatibility and performance.
