How to Convert TS to MKV on Windows 10/11 and Mac with High Quality

TS, called Transport Stream, is a video container format that holds video data using standard MPEG-2 video compression. It is typically used for storing video on a DVD disc and saved as multiple files on a DVD like moviename1.ts, moviename2.ts, moviename3.ts, etc. In general, TS files can be played back by DVD player software.

However, TS files tend to be large due to its extra features and checks meant to overcome poor transmission medium. On the other hand, TS files rely on the old MPEG codec, which is not supported by Windows 10/11, let alone the newer mobile devices, unless you install additional codecs.

For better compatibility, many users tend to convert TS to MKV in such a way to maintain good quality and ensure proper playback on more media players and devices. In this guide, we will go over how to convert video from .ts to .mkv format and provide reliable TS to MKV converter tools for you.

Way 2. with Handbrake


What we like:

  • Open-source and cross-platform.
  • Support DVD conversion.

What we dislike:

  • Support limited output formats MP4, WebM and MKV.
  • Tinkering with video settings is time-intensive and complicated for novices.

Handbrake has long been recognized as the go-to video transcoder that can freely convert both DVD and video sources to modern and universal codecs. Over the past few years, Handbrake has been updated and evolves into a much sought-after tool that opens you up to batch processing multiple video TS files at the same time, and extends a ton of presets for high-quality matroska, web, device, etc you are after, without tinkering with a lot of options.

Handbrake is not very approachable looking and not designed for beginners, and you may have trouble converting .ts file to .mkv and get an error “No valid source or titles found”, but as a free, open source, cross-platform video converter, Handbrake is undeniably an enticing option that can handle almost any video you throw at it, including the TS file. Follow the steps below to convert TS to MKV for free with Handbrake.

How to Convert TS to MKV Freely with Handbrake?

  1. When you launch Handbrake, it will prompt you to locate and open a file. Just load up a TS video you want to convert into Handbrake.
  2. Once you have selected the file, choose from a series of presets. To encode TS to MKV, you can go to the Matroska presets, including HEVC MKV, H.264 MKV, VP9 MKV, and VP8 MKV with resolution ranging from 4k 2160p to 480p. For high-quality MKV file, choose HEVC MKV 2160p, this will give high-quality output, but lead to lengthier transcoding and bigger file size. If you want to get a smaller MKV file and better compatibility, you can choose H.264 MKV 720p.
  3. Go to the Summary section and choose MKV as the output format.
  4. Here in the Output Setting section, you can customize precise encoding settings, change codecs, crop overly large videos, apply effects, tweak frame rates, and much more.

Way 3. with Winxvideo AI


What we like:

  • GPU accelerated. TS to MKV conversion speed is really fast.
  • Also a TS video compressor and editor.

What we dislike:

  • Software installation is required.

At its core, Winxvideo AI is a video encoding tool boasting 200+ video inputs and 420+ outputs, including TS, MKV, MP4, HEVC, H.264, AV1, WMV, DIVX, WebM, 3GP, etc, but it offers video compressor and editor features, in a minimalistic tool. With it you can encode TS files to MKV in one fell swoop and take full control over the output by adjusting the video resolution, codec, bitrate, etc.

There's no getting away from the fact that WinX is faster than rivals in the market when it comes to convert video files like TS. It takes full advantages of hardware acceleration tech to decode and encode video with GPU, and this means the conversion speed is accelerated and CPU is unburdened for other tasks to some extent.

In addition, WinX’s presets are likely to satisfy most users. You can fine-tune settings to maximize quality and minimize file size. In our test, video quality of output MKV HEVC is nearly indistinguishable from the source TS file, and storage size is almost 90% smaller than original. You can take a try and extract mkv files from ts as below.

How to Convert TS to MKV with Winxvideo AI?

  1. Free download the media encoder, install and launch it. Click Video Converter, +Video button to load a TS file. You can add several TS videos at a time to convert.
  2. Choose output format MKV from the preset profiles list.
  3. Optional: go to the Setting option, where you can tweak the video resolution, codec, bitrate, frame rate, and more. You have to bear in mind that higher resolution, bitrate and frame rate give rise to better quality but bigger file size. For best balance between quality and size, leave the settings unchanged.
  4. Click browse button to locate a folder where you want to save the converted ts file, and press RUN button to begin converting TS file to MKV video.
