Om konvertering från MTS till MKV

MKV (Matroska Video) is the most flexible open container format available, supporting virtually unlimited audio, subtitle, and chapter tracks with any codec combination. MTS/AVCHD files use the MPEG-2 Transport Stream container which, while functional, lacks support for embedded subtitles, multiple audio tracks, and chapter navigation. Converting MTS to MKV preserves or enhances the video while unlocking modern container capabilities.

Varför konvertera MTS till MKV?

Media server software (Plex, Jellyfin, Kodi, Emby) works best with MKV because it can extract and present multiple audio tracks, subtitle streams, and chapter markers to the viewer. AVCHD's MTS container supports none of these features. Converting camcorder footage to MKV enables adding subtitle tracks (for multilingual distribution), embedding chapter markers (for navigating long events), and carrying multiple audio mixes (original, commentary, music-only).

MKV also supports modern codecs that outperform AVCHD's H.264 encoding. Transcoding to H.265 or AV1 within MKV can reduce file sizes by 40-60% while maintaining or improving visual quality. For media library management, MKV's rich metadata and flexible structure make it the container of choice.

Vanliga användningsområden

Building Plex/Jellyfin libraries from AVCHD camcorder footage with proper metadata
Adding subtitles and chapter markers to camcorder event recordings
Transcoding AVCHD to H.265 in MKV for efficient storage of large video archives
Combining multiple AVCHD audio tracks (different microphones) into a single MKV file
Archiving camcorder footage in a future-proof container that supports any codec

Så fungerar det

For a fast remux preserving the H.264 stream: `-c:v copy -c:a copy -f matroska`. Note that deinterlacing requires re-encoding: `-vf yadif -c:v libx264 -crf 20 -c:a aac -b:a 192k`. For H.265: `-vf yadif -c:v libx265 -crf 24 -c:a aac -b:a 192k`. MKV supports adding external subtitles: `-i subs.srt -c:s srt`. Use MKVToolNix post-conversion to add, remove, or reorder tracks.

Kvalitet & prestanda

Remuxing (stream copy) preserves exact AVCHD quality with zero loss. Re-encoding to H.264 CRF 20 is visually lossless. H.265 at CRF 24 matches H.264 CRF 20 quality at 30-40% smaller file sizes. The main quality improvement comes from deinterlacing, which eliminates combing artifacts on progressive displays.

Tips för bästa resultat

1Use remux (stream copy) for speed when you do not need deinterlacing or compression — it takes seconds
2Add chapter markers at clip boundaries when merging multiple MTS files into one MKV
3Include both AC3 (original surround) and AAC (compatible stereo) audio tracks for maximum playback flexibility
4Use MKVToolNix after conversion to fine-tune track order, default tracks, and metadata without re-encoding
5For Plex/Jellyfin, name files as 'Title (Year).mkv' for automatic metadata matching and artwork fetching

MTS to MKV conversion upgrades AVCHD camcorder recordings into the most versatile container format, enabling rich metadata, multiple tracks, and modern codec options for media library management and long-term archival.

Vanliga fragor

Yes. The H.264 stream copies directly into MKV at full speed with zero quality loss. However, the video remains interlaced — add deinterlacing only if you also re-encode.

Most modern smart TVs (Samsung, LG, Sony, 2015+) play MKV with H.264 and AAC. Some older models may not recognize MKV despite supporting the codecs inside. MP4 has broader TV compatibility.

Yes. FFmpeg's concat filter or MKVToolNix's chapter-based merging can combine multiple MTS clips into a single MKV file with chapter markers at each clip boundary.

MKV supports AC3 audio natively. You can copy the AC3 stream directly or transcode to AAC for broader device compatibility. You can even include both tracks in the same MKV.

H.265/HEVC in MKV plays on Plex, VLC, Kodi, mpv, and most 2018+ smart TVs. Some older devices may struggle. For maximum compatibility, H.264 in MKV is safer.

Yes. MKV supports subtitle track flags including 'forced' and 'default'. Media players respect these flags, showing forced subtitles automatically and default subtitles when the user enables them.
