About formats

M2V is a file format containing MPEG-2 video elementary streams without an encapsulating container or associated audio data. Standardized as part of ISO/IEC 13818-2 (also known as ITU-T H.262) by the Moving Picture Experts Group in 1995, M2V stores raw compressed video exactly as it would appear within an MPEG-2 program or transport stream, but stripped of all multiplexing overhead. This makes M2V files primarily useful in professional authoring workflows, particularly DVD production, where video and audio streams are prepared and encoded separately before being muxed together into the final container format. M2V streams support both interlaced and progressive scan modes at resolutions ranging from standard definition up to 1920x1080 HD, with bit rates typically ranging from 2 to 15 Mbps for consumer content and up to 80 Mbps in professional applications. The use of both intra-coded frames and predictive frames provides an effective balance between compression efficiency and random access capability. Because M2V contains only video with no audio or synchronization information, it requires pairing with a separate audio file for complete playback. DVD authoring software commonly expects M2V input alongside AC3 or LPCM audio files, making this format an essential intermediate step in professional disc mastering and broadcast preparation workflows.
Initial release: July 1995
HCOM is a Huffman-coded audio format from the early Macintosh era, designed to shrink digitized sound for distribution on floppy disks and bulletin board systems when storage was precious and modems were slow. The encoder takes 8-bit unsigned PCM input, computes a frequency table of sample-delta values, and builds an optimal Huffman tree that replaces common deltas with short bit sequences. Compression ratios of 2:1 or better were typical for speech recordings, a meaningful saving when a 3.5-inch floppy held only 800 KB. Files were distributed as Macintosh resource forks and played through utilities like SoundApp and the BinHex ecosystem that defined Mac software exchange in the late 1980s. The format supported sample rates up to 22.255 kHz, matching the output capabilities of original Macintosh sound hardware. Tools such as SoX retain HCOM decoding support, ensuring that archived recordings remain accessible decades later. HCOM holds three practical advantages for preservation work: lossless compression that recovers the original samples exactly, a self-contained Huffman table embedded in each file for dependency-free decoding, and historical prevalence across thousands of vintage Mac sound archives.

Frequently Asked Questions

Why convert M2V to HCOM?

Converting M2V to HCOM extracts whatever audio data accompanies the video stream, producing a standalone audio file for any player.

How do I open an HCOM file?

Macintosh sound tools and legacy audio converters support HCOM compressed audio.

What happens to my uploaded files?

Uploaded M2V files are deleted from our servers immediately after processing. Converted HCOM files are auto-removed within 24 hours.

Can I convert several files at once?

Yes. Upload multiple M2V files and extract HCOM audio from each one in a single batch operation — fast and convenient.

Do I need to install anything?

Not at all. The converter runs in your web browser — no downloads, plugins, or desktop applications are required for the conversion.
