Video Commander

MP4 Inspector for macOS

Need to know what codec an MP4 uses, how its tracks are laid out, or why a player rejects it? The answers live inside the file's box structure — hard to read from a terminal dump.

Open any MP4 and check its codecs, tracks, and ISOBMFF box structure visually with Video Commander — built for engineers. Then convert, run VMAF, or package HLS/DASH in the same desktop app.

Frequently Asked Questions

How do I check what codec an MP4 uses on a Mac?: Open the file in Video Commander and the stream overview shows the video and audio codecs, resolution, frame rate, bitrate, and duration — no ffprobe command required. It is a free download for macOS.
Is there a free MP4 inspector for macOS?: Yes. Video Commander is a free download for macOS with no subscription. It inspects MP4/ISOBMFF files locally, showing codecs, tracks, box structure, and per-sample layout in a visual interface.
Can I view the MP4 box (atom) structure without the command line?: Yes. Instead of reading mp4dump or MP4Box output in the terminal, Video Commander presents the ISOBMFF box hierarchy as a navigable tree, down to individual sample tables.
Does Video Commander work on Apple Silicon?: Yes. Video Commander supports both Apple Silicon (M-series) and Intel Macs.
