M2V to W64 Converter
Processing entirely on your device — large files may take a moment.
Convert W64 recordings to WAV or FLAC for standard editors. If your files are still in M2V format, this page is the shortcut: M2V is a raw MPEG-2 video elementary stream — DVD and broadcast video stripped of its container, the export format of choice of many editors.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the M2V format
M2V is the MPEG-2 video elementary stream — the video layer of DVDs and digital broadcast, exported bare by editors who want to mux it with audio separately. It is the professional half of a DVD's guts.
Muxing M2V with its audio into MP4 or MKV restores a playable file; the video often stream-copies without re-encoding since MPEG-2 data is already valid in modern containers.
+ Strengths
- ✓Broadcast/DVD grade MPEG-2 quality
- ✓Often stream-copyable without re-encode
- ✓Standard editor export format
! Limitations
- −No audio inside — pair it before muxing
- −Large for HD (MPEG-2 efficiency)
- −Interlaced flags need care
About the W64 format
W64 is Sony's Wave64 — what happens when WAV's 32-bit size fields run out of road. A RIFF variant with 64-bit offsets, it shrugs off the 4 GB ceiling that makes plain WAV choke, which is why long field-recording sessions and Sony Vegas projects land in W64.
Inside, it is the same uncompressed PCM as WAV — ffmpeg hands W64 to WAV, FLAC or MP3 without touching a single sample, so conversion is purely about container compatibility.
+ Strengths
- ✓No 4 GB size ceiling — hours-long recordings
- ✓Bit-exact PCM, same as WAV inside
- ✓Standard in Sony Vegas workflows
! Limitations
- −Almost nothing outside Sony tools opens it
- −Uncompressed — very large files
- −Legacy niche — new tools prefer RF64
Why convert M2V to W64?
There is a concrete reason this conversion exists: No audio inside — pair it before muxing W64 sidesteps that — No 4 GB size ceiling — hours-long recordings If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this M2V to W64 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for M2V to W64?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does converting M2V to W64 re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of W64, staying in sync with the video. If your M2V file has multiple audio tracks, the first one is used.
