MP4Splitter
MP4Splitter is a free, lightweight video utility that splits MP4 files into smaller segments without re-encoding. It operates as a graphical frontend to ffmpeg and mp4box, allowing users to divide videos by duration or file size with a few clicks. The tool is commonly used for splitting large video files to meet platform upload limits (such as social media size caps) or for organizing lengthy recordings into manageable chunks. MP4Splitter is part of the broader MP4Tools suite, which also includes MP4Joiner for combining multiple MP4 files.

1 suggestionMP4Splitter has not been updated since November 2019 — the latest release is version 3.8 from that date, nearly seven years old at this point. No native Apple Silicon build has been shipped, and there is no evidence of ongoing development. The Intel-only binary will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). While MP4Splitter is currently functional under Rosetta, you should begin planning an alternative now. For straightforward MP4 splitting without re-encoding, FFmpeg-based tools with native Apple Silicon support include Handbrake (which can cut/split video), or command-line alternatives like ffmpeg itself (installable via Homebrew and natively compiled for Apple Silicon). For a GUI-driven experience, consider MediaInfo, Shotcut, or VidCutter — all are actively maintained and run natively on M-series Macs. If you need a direct replacement with minimal learning curve, Shotcut offers a similar split-and-export workflow and is free and open-source.
