Supports: MKV
This tool re-encodes the video from an MKV file into a raw .m2v — an MPEG-2 video elementary stream. The single most important thing to know up front: the audio is dropped. An .m2v has no place to put a soundtrack, so the output is silent video-only by design — and MKV-only extras like subtitle tracks and chapter markers are dropped too. That bare elementary stream is exactly what DVD-authoring and MPEG-2 editing pipelines want, but if you just need a playable MKV replacement, you almost certainly want MKV to MPG (audio included) or MKV to MP4 instead.
The two formats are not competing containers — one is a full container, the other is a bare stream. That difference explains everything the conversion drops.
| Property | MKV (source) | M2V (output) |
|---|---|---|
| What it is | A container that wraps several streams together | A single video elementary stream, no container at all |
| Standard | Matroska, an open EBML-based format announced in December 2002 | ITU-T H.262 | ISO/IEC 13818-2, ratified in the mid-1990s |
| Video codec | Anything — commonly H.264, H.265, or AV1 | MPEG-2 only; the stream is the codec |
| Audio | Multiple tracks, any codec | None — nowhere to put it |
| Subtitles | Soft subtitle tracks plus embedded fonts | None |
| Chapters and tags | Yes | None |
| Seek index | Yes, built into the container | None; players scrub poorly or refuse the file |
| Plays in normal media players | Widely | Unreliably, and it will be silent |
| Built for | Playback, ripping, archiving | DVD authoring and MPEG-2 editing pipelines that mux audio separately |
M2V is the video half of an MPEG-2 stream, defined by ITU-T H.262 | ISO/IEC 13818-2 (ratified in the mid-1990s). That standard specifies a video codec and says nothing about audio. A file saved with a plain .m2v extension is an elementary stream: a single media type — a sequence of coded MPEG-2 frames — with no container wrapped around it to hold a parallel audio track or the subtitle and chapter data an MKV can carry. So there is nowhere for your MKV's audio to go, and the converter discards it.
In DVD authoring and broadcast workflows this is exactly what you want. The video is mastered as .m2v and the audio is mastered as a separate file — usually .ac3 (Dolby Digital) or LPCM .wav. Authoring tools such as DVDAuthor and TMPGEnc deliberately keep the two apart and only join ("mux") them later into a combined container like VOB. If you need the audio kept, extract it on its own with MKV to MP3 or, for the Dolby Digital track DVD tools expect, MKV to AC3.
.mkv onto the page, or click "+ Add Files" to choose it from your computer. You can queue several files to process with the same settings..m2v elementary stream can carry..m2v. No sign-up, no watermark.Because the M2V is destined for a DVD or an MPEG-2 timeline rather than direct playback, the settings that matter are the ones a DVD spec cares about — bitrate ceiling and frame size — not codec choice (it is always MPEG-2 here). Note that most MKV files store H.264 or H.265 video, so going to MPEG-2 is a backward re-encode: quality drops and the file usually grows, because MPEG-2 is far less efficient than the codec your MKV started with.
For reference, these are the constraints a DVD-Video authoring tool checks the .m2v against:
| Setting | NTSC target | PAL target |
|---|---|---|
| Full-D1 frame size | 720×480 | 720×576 |
| Frame rate | 29.97 fps (or 23.976 fps carrying pulldown flags) | 25 fps |
| Display aspect ratio | 4:3 or 16:9 | 4:3 or 16:9 |
| Video codec | MPEG-2, the only codec an .m2v carries |
MPEG-2 |
| Practical video bitrate | Around 6–8 Mbps | Around 6–8 Mbps |
| Spec ceiling | About 9.8 Mbps for video, roughly 10.08 Mbps for everything combined | Same |
| Audio | Separate file — usually AC-3 or LPCM, muxed later | Separate file — usually AC-3 or LPCM, muxed later |
DVD-Video also permits smaller half-D1 and SIF frame sizes, but the full-D1 values above are what authoring tools expect by default. Whatever you pick, remember the result is mute — pair it with the matching audio file at the muxing stage.
.m2v is video-only; there is no audio track to play. Extract the sound separately with MKV to MP3 or MKV to AC3..m2v is often larger. If you do not actually need MPEG-2, use MKV to MP4 for a much smaller, modern file.M2V is the right target only for DVD authoring and MPEG-2 editing pipelines that expect a demuxed elementary stream. If you are reaching for it because you want a smaller, more compatible, or playable video, it is the wrong tool — the result is silent, drops your subtitles and chapters, uses an old codec, and will not open cleanly in most players. For everyday use, convert your MKV to a real container instead: MKV to MPG gives you an MPEG program stream that carries the audio, and MKV to MP4 gives you a modern, widely playable file. Reach for .m2v only when an authoring tool specifically asks for an MPEG-2 video elementary stream.
Because .m2v is an MPEG-2 video elementary stream and holds picture only. The format, defined by ITU-T H.262 / ISO/IEC 13818-2, specifies a video codec with no provision for an audio track, and a bare elementary stream has no container to hold one. So the MKV's audio is dropped during conversion and the output is silent by design. If you need the sound, extract it separately with MKV to MP3 or MKV to AC3.
They are discarded, not stored on the side. M2V can only carry video, so the audio, subtitle tracks, and chapter markers your MKV held all live in the MKV container and have nowhere to go in an elementary stream. In a DVD-authoring workflow you would create the audio as its own file in a separate pass — typically .ac3 or .wav — and mux it with the .m2v later. To get that audio file, run a second conversion: MKV to AC3 for the Dolby Digital track DVD tools expect, or MKV to MP3 for a general-purpose copy.
Choose M2V only if an authoring or editing tool specifically asks for a raw MPEG-2 video elementary stream — it is silent and not meant for direct playback. For almost everything else, use MKV to MPG: an MPEG program stream wraps the video and audio together into one playable file, so you keep your soundtrack and the result opens in normal media players.
Most MKV files store H.264 or H.265 video, which are far more efficient than MPEG-2. Converting to .m2v re-encodes that video to the older MPEG-2 codec, so at a comparable quality the output is often bigger, not smaller. In our testing, a typical H.264 MKV grows noticeably when re-encoded to MPEG-2 at DVD-grade quality. That is the expected trade-off for MPEG-2 compatibility — if a smaller file is the goal, convert to MKV to MP4 instead.
DVD-Video accepts only 720×480 for NTSC or 720×576 for PAL, so set Video resolution to Width x Height and type those numbers before converting — the Preset Resolutions list is height-only and lets the width follow your source aspect, so it cannot land on a DVD-legal frame. The DVD video bitrate is capped around 9.8 Mbps (shared with the audio), and most guides keep the video at roughly 6–8 Mbps to leave room for the separate audio stream. An off-spec frame size is the most common reason a DVD-authoring tool rejects an imported .m2v.
You mux them, which is a separate step from converting. DVD-authoring software such as DVDAuthor and TMPGEnc is built around exactly this: you hand it the .m2v for picture and a matching .ac3 or .wav for sound, and it writes them into the VOB files that make up the disc. General-purpose muxing tools can also wrap the pair into a single container without re-encoding either stream. The important part is producing the audio at the same length and frame rate reference as the video, so run the audio extraction from the same source MKV rather than a differently trimmed copy.
Match the television standard the disc is for: 29.97 fps for NTSC or 25 fps for PAL. Film-sourced material is commonly encoded at 23.976 fps with pulldown flags so an NTSC player reconstructs 29.97 fps on playback, which is why some authoring tools accept that rate as well. Do not resample a 25 fps European source to 29.97 or vice versa unless the disc really is for the other standard — the conversion introduces judder that no later step removes.
Your MKV is uploaded over an encrypted connection, converted on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up and no watermark, and your files are never shared or made public.
