HOW TO CONVERT MKV → TS
Provide the MKV clip
Upload through the browser; transfers are encrypted end-to-end and files are quarantined per session.
Convert to TS
The conversion keeps resolution, frame rate and bit depth identical to the source unless you explicitly override them.
Save to your device
Click download to pull the TS to local storage; share the short-lived URL with collaborators if needed.
Starting point: MKV is the Matroska container, flexible enough to carry nearly any codec plus chapters and subtitles. Natural next step, a TS. A MKV to TS conversion rescues a clip that refuses to play somewhere important — a phone, a smart TV, a web uploader. KaijuConverter uses FFmpeg under the hood, the same engine video professionals rely on, and prioritises stream-copy over re-encode so the output stays faithful to the source. Technical note: MKV is the Matroska container, flexible enough to carry nearly any codec plus chapters and subtitles. Compare that with TS is the MPEG transport stream, used in broadcast and HLS streaming segments.
Why convert MKV to TS
The usual reason to convert from MKV into TS is the same reason anyone transcodes video: the original container is not accepted where you are trying to send the file. Swapping to TS flips that rejection into a clean upload without altering the footage itself.

MKV vs TS — Strengths and limitations
What each format does best, and where it falls short.
MKV Strengths
- Carries virtually any codec — H.264, H.265, AV1, VP9, Opus, FLAC, AAC, you name it.
- Multiple audio and subtitle tracks, chapters, and menus in one file.
- Patent-free container — no licensing fees.
- Attached fonts and metadata ride along for self-contained playback.
- Streamable and seekable with built-in index/cue tables.
Limitations
- Not natively supported in Apple's QuickTime or Safari without third-party tools.
- Windows needed codec packs (or "Films & TV" app updates) to play it out of the box.
- Hardware decoders on older TVs and streamers often reject MKV.
TS Strengths
- Designed for noisy channels — packet-level error correction.
- Multi-program: one TS can carry several TV channels.
- Native format for all digital TV broadcasts and HLS streaming.
- Streaming-first: no need to download whole file to start playing.
- 30+ years of stable, deployed infrastructure.
Limitations
- Packet overhead (~3% vs Program Stream).
- Seek index is implicit — requires scanning for random access.
- Multiple audio/subtitle selection requires parsing PMT (Program Map Tables).
Quality & Compatibility
The conversion does not upscale or sharpen the video. A 1080p MKV produces a 1080p TS; a 4K source stays 4K unless you select a lower output resolution explicitly. Picking higher bitrates does not improve perceived quality beyond the source ceiling.
Tips for Best Results
- If your MKV has variable frame rate, force a constant frame rate in TS to avoid stuttering on some players and streaming platforms.
- For screen recordings at high resolution, quality 22 CRF H.264 keeps text perfectly readable at a fraction of the source size.
- Check the audio track after transcoding — some MKV containers carry unusual audio codecs that downgrade subtly when remapped to TS.
Frequently Asked Questions
Only when it has to. If the codecs inside MKV (usually H.264 or H.265 for video, AAC for audio) are accepted by TS, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
Matroska Video
Source formatMKV is a flexible, open-standard container format that can hold unlimited video, audio, subtitle, and metadata tracks. It is popular for high-definition video and supports virtually any codec.
MPEG Transport Stream
Target formatTS (Transport Stream) is used for broadcasting, streaming, and recording live TV.
Going the other way? Convert TS back to MKV with the same engine.
Common Use Cases
Share across platforms
Send TS files to anyone without worrying about whether they have the right software for MKV.
Embed in documents
Drop TS output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TS often produces smaller files than MKV for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
