.m2v elementary stream. There is no audio track in the output (M2V is video-only); pair it with an external AC-3 or LPCM audio file in your authoring tool.Xvid is an MPEG-4 Part 2 (Advanced Simple Profile) codec, typically wrapped in an AVI container with an MP3 or AC-3 audio track. M2V is something fundamentally different: a raw MPEG-2 video elementary stream — video data only, no container, no audio, no metadata. The conversion is almost always one step inside a DVD-Video authoring pipeline, where video, audio, and subtitles are kept as separate elementary streams and multiplexed into VOB files at burn time.
.m2v + .wav (or .ac3) files. Exporting to M2V at the right bitrate avoids re-encoding inside Encore, preserving picture quality.| Property | Xvid (in AVI) | M2V |
|---|---|---|
| Codec standard | MPEG-4 Part 2 ASP (ISO/IEC 14496-2) | MPEG-2 Video (ISO/IEC 13818-2) |
| Container | AVI (typical) | None — raw elementary stream |
| Audio | Inside AVI (MP3, AC-3) | Video only — no audio carried |
| Released / standardized | Codec released 2001; US patents expired Nov 2023 | MPEG-2 standardized 1995–1996 |
| Typical bitrate | ~700 kbps–2 Mbps for SD | 4–9.8 Mbps for DVD-Video |
| Primary use | PC playback, AVI rips | DVD authoring, broadcast handoff |
| GOP / structure | I/P/B frames, ASP features | Strict GOP rules — max 18 frames NTSC, 15 PAL |
| Direct DVD-Video compliance | No | Yes — when at NTSC/PAL DVD specs |
| Scenario | Resolution | Bitrate (CBR) | Notes |
|---|---|---|---|
| Short DVD (≤60 min) | 720×480 / 720×576 | 8,000 kbps | High quality; full DVD picture peak |
| Standard DVD (60–120 min) | 720×480 / 720×576 | 5,000–6,000 kbps | Common for single-layer DVD-5 |
| Long DVD (120–180 min) | 720×480 / 720×576 | 3,500–4,500 kbps | Trades quality for runtime |
| Half-D1 / re-encode safe | 352×480 / 352×576 | 2,000–3,000 kbps | Lower-res DVD-compliant subprofile |
| Broadcast / HDV intermediate | 1920×1080 (interlaced) | up to 25 Mbps | Beyond DVD-Video peak; for HDV workflows |
DVD-Video peaks at 9.8 Mbit/s for video and 10.08 Mbit/s for video+audio combined. Going above those caps produces an M2V that won't play on hardware DVD players.
That's by design. M2V is the MPEG-2 video elementary stream — it stores compressed picture data only. Audio is stored separately in .ac3, .mp2, .wav (LPCM), or .dts and the two are multiplexed into a single VOB file by the DVD authoring tool. If you want a single audio+video file, target MPEG-2 Program Stream (.mpeg) or MP4 instead.
For a 60–120-minute DVD-5 disc, 5,000–6,000 kbps Constant Bitrate is a common sweet spot. Short discs can use 8,000 kbps; long-runtime discs drop to 3,500–4,500 kbps. The DVD-Video spec caps video at 9.8 Mbit/s and combined video+audio at 10.08 Mbit/s — exceed it and hardware players reject the disc.
NTSC: 720×480, 704×480, 352×480, or 352×240. PAL: 720×576, 702×576, 352×576, or 352×288. The Resolution Preset dropdown surfaces 480P and 576P as one-click options. Keep the same field rate as the source — interlaced NTSC at 29.97 fps or PAL at 25 fps — and let your authoring tool flag the display aspect (4:3 or 16:9).
Yes — Encore's preferred DVD asset is a .m2v video file paired with a .wav or .ac3 audio file. Adobe's Premiere Pro "MPEG-2 DVD" export preset produces exactly that pair. Importing pre-encoded DVD-compliant M2V skips Encore's transcode step, which preserves the original picture quality.
DVDStyler accepts MPEG-2 elementary streams and program streams. If the M2V matches DVD-Video specs (720×480/576, ≤9.8 Mbps, correct field rate), DVDStyler muxes without re-encoding. Pair the M2V with an AC-3 audio file in DVDStyler's track inspector and the export is direct to VOB.
Convert the original AVI's audio track separately. The original Xvid AVI usually carries MP3 or AC-3 — extract it with FFmpeg (ffmpeg -i input.avi -vn -acodec copy audio.ac3 if it's already AC-3) or transcode to AC-3 / LPCM. Add that audio file alongside the M2V in your DVD authoring tool. xconvert can also convert the AVI to AC-3 separately.
VLC handles raw .m2v streams natively and shows picture without audio. QuickTime, Windows Media Player, and Media Player Classic will also open M2V on systems with an MPEG-2 decoder installed. For everyday playback of a finished video, convert to M2V back to MP4 instead — M2V is an authoring intermediate, not a playback format.
Xvid is GPL-licensed and free to redistribute. The relevant US MPEG-4 Part 2 patents (which Xvid implements) expired in November 2023, so the codec itself is now patent-free in the US. The output M2V is MPEG-2; many MPEG-2 patents have also expired but the situation varies by jurisdiction — check current status if you're producing commercial discs.
.mpeg (or .mpg) is usually an MPEG-2 Program Stream that interleaves video, audio, and timing into one file ready for playback. .m2v is the MPEG-2 video elementary stream alone — no audio, no PES packetization. Authoring tools want elementary streams; players want program or transport streams. Use Xvid to MPEG for a playable single file, or this page for the authoring-ready M2V.
