It supports video codecs H.264, VC-1, MPEG2 and audio codecs AAC, AC3 / E-AC3(DD+), DTS/ DTS-HD. With it, you can set muxing fps manually or automatically, change level for H.264 streams, shift a sound tracks, extract DTS core from DTS-HD, and join files.

When authoring mkv to a Blu-ray Disc or AVCHD, the video and audio remain untouched, so the quality is not impacted and the process is very fast.

1. Load the mkv file to tsMuxeR and soft subs, if you’d like to mux the subtitle. You can see the detailed information of the media file:codec, fps, tracks, etc.
2. Check blu-ray disk option. Set audio language if needed. Select Output type, here we will create blu-ray disk. Choose a folder to save the output file.
   
3. Enable the General tab, set the bit rate.
   
   Constant Bit Rate (CBR) encoding means that you encode a file at a fixed rate, such as 128 Kpbs. For many people this is a common method of encoding MP3s.
   Variable Bit Rate (VBR) encoding is a method that ensures high audio quality bit-allocation decisions during encoding. The encoder allocates an appropriate amount of data per second, depending on the complexity of the audio file.
   Here I use tsMuxeR’s default mux VBR.
4. On the Blu-ray tab, create chapters manually or automatically.
   
5. To hardcode the subtitle, you need to adjust the position of subtitles on the screen.
6. In addition, you can split the file or cut off the part you want to get rid of. Click Start Muxing to create the blu-ray structure.
