In pass-through mode, Yuhan Blu-ray Creator and Yuhan 4K UHD Creator can only support M2TS files with AC3+TrueHD (Dolby Atmos) composite streams, and you can use the tool TsMuxer (https://www.videohelp.com/software/tsMuxeR) to generate M2TS files.

 

1. Generate AC3 + TrueHD (Dolly Atmos) composite stream

You can use the eac3to widget to convert a TrueHD stream to AC3+TrueHD with the following command:

eac3to input.thd output.thd+ac3

Or use Yuhan Blu-ray Creator’s Transcode mode to preserve TrueHD to generate a composite stream of AC3+TrueHD.

 

2. Use TsMuxer to generate an M2TS file from the original video stream and the newly generated AC3+TrueHD composite stream.

 

 

3. Load new M2TS File, at this point, it will only show one TrueHD stream

 

4. Set Passthrough mode
