Supports: MKV
MKV (Matroska, 2002) is the flexible open-source container the modern ripping and Plex / Jellyfin world standardized on — it carries any codec (H.264, H.265, AV1, VP9), unlimited audio tracks, soft subtitles, chapters, and metadata. MPEG-2 (ISO/IEC 13818-2, 1996) is the older codec baked into the DVD-Video spec and most broadcast workflows. Converting MKV to MPEG-2 is what you do when you need to take a modern rip back to a hardware-decodable format for DVD authoring, broadcast playout, or a legacy player that refuses anything newer.
| Property | MKV (Matroska) | MPEG-2 (.mpeg2 /.m2v /.mpg) |
|---|---|---|
| Standardized | Matroska, 2002 (open spec) | ISO/IEC 13818-2, 1996 |
| Container or codec | Container (codec-agnostic) | Video codec (carried in MPG/M2V/TS/VOB) |
| Typical video inside | H.264, H.265, AV1, VP9, MPEG-2, MPEG-4 | MPEG-2 only |
| Typical audio inside | AAC, AC-3, DTS, FLAC, Opus, Vorbis, TrueHD | MP2, AC-3, LPCM |
| Subtitles | Soft (SRT, SSA, PGS) — switchable | Not standard in elementary stream |
| Multiple audio tracks | Yes — unlimited, switchable | Typically one |
| Chapters / metadata | Native | None |
| DVD-authoring tool support | Limited — usually requires re-encoding | Native input |
| Browser playback | None natively | None natively |
| Hardware decoder coverage | Modern devices (depends on internal codec) | Every DVD player, STB, broadcast deck since 1996 |
| Typical bitrate (SD) | 1-3 Mbps (H.264) | 4-9 Mbps |
| Compression efficiency | 2-5× MPEG-2 (H.264 / H.265) | Baseline 1995 design |
| Output video codec | File size vs MKV source | Best for |
|---|---|---|
| MPEG-2 (default) | 2-3× the MKV size at matching quality | DVD authoring, broadcast, legacy hardware |
| MPEG-1 | Larger than MPEG-2 at matching quality | VCD-era players, embedded systems |
| MPEG-4 / DivX / Xvid | ~1.5× the MKV size | Older DivX / Xvid hardware boxes |
| H.264 | Same or smaller than MKV | If your target accepts H.264 in this container |
| H.265 / HEVC | ~50% of source | Modern decoders, smaller archives |
| Output audio codec | Notes |
|---|---|
| MP2 (default) | Standard MPEG audio — accepted by every DVD-authoring tool and broadcast deck |
| AC-3 (Dolby Digital) | Preserves 5.1 surround if the MKV has it; widely supported by authoring tools |
| AAC | Higher efficiency but not part of the DVD-Video spec — pick only if your downstream player accepts it |
| MP3 | Common for general playback; not DVD-Video-spec |
Yes. MPEG-2 is a different codec generation from H.265, so a re-encode is unavoidable — there's no remux path. The output will be 3-5× larger than the H.265 source at matching visual quality (a 1 GB H.265 MKV typically becomes a 3-4 GB MPEG-2 file at default settings). Pick the "Highest" quality preset or CRF 18 for an archival-quality re-encode, or accept the default ~4 Mbps CBR for a DVD-budget bitrate.
MPEG-2 elementary and program streams typically carry one video and one audio track — they don't have first-class slots for multiple audio languages or soft subtitles the way MKV does. The default conversion writes the first audio track and drops the others; soft subtitles (SRT, SSA, PGS) are dropped. If multi-track preservation matters, target a different container — see MKV to MP4 for an MP4 that keeps multiple audio tracks, or MKV to MOV for QuickTime workflows.
MPEG-2 if you're authoring a DVD-Video disc, feeding broadcast playout, or targeting any device that explicitly requires MPEG-2 — it's the only codec the DVD-Video spec accepts for video. MPEG-4 / Xvid / DivX produces ~30-50% smaller files at comparable quality and is the right pick for older DivX-certified DVD players, embedded car STBs, or generic playback on legacy hardware that lists DivX support. If unsure and the goal is DVD authoring, stay on the MPEG-2 default.
NTSC DVDs are 720×480 (USA, Canada, Japan), PAL DVDs are 720×576 (Europe, Australia, most of Asia). Picking either as a custom width × height matches the DVD-Video spec exactly. Resizing a 1080p or 4K MKV down to 720×480 is required for DVD playback — leave at 1080p / 2160p only if you're not authoring a disc and your downstream tool accepts higher MPEG-2 resolutions. Upscaling beyond the MKV's native dimensions doesn't recover detail and just inflates the bitrate.
Yes — pick AC-3 as the audio codec. AC-3 (Dolby Digital) is one of the audio formats the DVD-Video spec officially carries, and choosing it passes the MKV's AC-3 5.1 track through bit-for-bit. If the MKV has DTS, FLAC, TrueHD, or Atmos audio, those re-encode to AC-3 (loses Atmos object metadata but preserves channel count). MP2 (the default) is stereo-only.
There's no fixed cap — Conversion runs on our servers, so the limit is upload size and connection speed and upload patience. Multi-GB MKV rips (10-30 GB blu-ray or DVD rips, full-season packs) work fine — they're uploaded and processed on our servers, so your device isn't the limit. There's no quantity limit on batch jobs either, unlike the 100 MB free cap on Convertio and similar online competitors.
Use the Trim option once per episode. Set a start time and duration in HH:MM:SS.sss format (e.g., start 00:00:00, duration 00:24:30 for a 24-and-a-half-minute first episode, then 00:24:30 / 00:24:30 for the second), and run the conversion once per range. Each output is a clean MPEG-2 file that DVD-authoring tools accept as its own title or chapter. Merge later if needed with Merge Video.
Yes — see MPEG-2 to MKV for the reverse, useful if you're pulling DVD rips into a Plex / Jellyfin library. For modern targets, also see MKV to MP4 (universal playback) and MPEG-2 to MP4 (DVD-rip modernization).
