Frequently Asked Questions

Everything you need to know about this conversion tool.

MKV (Matroska Video) is an open container format that can hold virtually any video codec, audio codec, and subtitle format. It's popular because it's flexible, well-supported by media players, and not controlled by any corporation.

No. MKV is a container format (the "box"), while H.264 and H.265 are video codecs (the "content inside the box"). An MKV file can contain video encoded with H.264, H.265, AV1, or many other codecs.

Yes. If your input file uses a codec already compatible with MKV (H.264, H.265, AAC, etc.), you can select "stream copy" to remux the video without re-encoding — resulting in instant conversion with no quality loss.

Some smart TVs have limited codec support within MKV containers. If your TV supports H.264 MP4 but not H.265 MKV, convert the video to H.264 inside the MKV container, or use our MP4 Converter instead.

If your source file contains embedded subtitle tracks (e.g., from an MP4 with subtitle streams), they can be preserved in the MKV output. External SRT files cannot be added through this tool — use a dedicated muxing tool like MKVToolNix for that.

AVI is a 1990s format with limited codec support and no subtitle/chapter capabilities. MP4 is widely compatible but less flexible. MKV supports the widest range of codecs, multiple streams, and advanced features — making it ideal for archiving and home theatre.

MKV Matroska Container: The Home Theatre Standard Explained

MKV (Matroska Video) is the format of choice for serious home theatre enthusiasts, media server operators, and digital archivists. Its open design, unlimited flexibility, and broad player support make it the premier container for any video that deserves more than the basics.

What Makes MKV Different from MP4?

While MP4 and MKV can both hold H.264 and H.265 video, they differ significantly in capability:

Audio tracks: MP4 supports limited multi-track audio; MKV supports unlimited tracks including DTS-HD, Dolby Atmos, and TrueHD.
Subtitles: MP4 supports limited subtitle formats; MKV supports SRT, ASS, PGS, and many more simultaneously.
Error recovery: MKV has superior error recovery — partial files can often still be played.
Chapters: Both support chapters, but MKV's implementation is richer and more commonly used.

Plex, Kodi, and Jellyfin: Why MKV Is the Media Server Format

Plex and Kodi both natively support MKV with H.264 and H.265 for direct play — meaning the file streams to your TV or client without any server-side transcoding. Transcoding burns CPU, introduces lag, and downgrades quality. Keeping your library in MKV format avoids this entirely.

Plex recommends MKV with H.264 or H.265 and AAC or AC3 audio for the broadest client compatibility across Smart TVs, Rokus, and Fire Sticks.

MP4 to MKV: When to Use Remux vs Re-encode

If your MP4 already uses H.264 or H.265 video, converting to MKV can be done as a remux — the video data is moved to the MKV container without touching a single frame. This is lossless, instant, and the correct choice in nearly all cases.

Re-encoding is only needed when you want to change the codec (e.g., H.264 → H.265) or when the source audio uses a format incompatible with MKV (rare).

Embedding Subtitles in MKV

One of MKV's most valued features is soft-subtitle embedding — storing subtitle text inside the container so media players can toggle them on/off at will. SRT, ASS, and VTT subtitle tracks can all coexist inside a single MKV file.

This is a major advantage over MP4, which has limited support for embedded subtitles. For workflows requiring subtitle embedding alongside video conversion, MKV is the professional choice.

MKV for 4K HDR: The Technical Advantage

4K HDR video requires a container that can carry HDR metadata (HDR10, HDR10+, Dolby Vision) alongside the video stream. MKV fully supports all HDR formats, making it the standard container for 4K Blu-ray rips and HDR home theatre files.

For HDR content, always use MKV with H.265/HEVC — it's the only combination that preserves the full HDR colour grading and dynamic range intended by the filmmakers.
