TSM2UHD

TSM2UHD is a small utility created for users who want to modify the structure of tsMuxeR-generated Blu-Ray folders so they can be played on standalone Ultra HD Blu-Ray players without requiring additional applications. It is particularly useful for those working with tsMuxeR BD files that fail to meet the strict specifications of UHD-BD hardware.

The program analyzes the output created by tsMuxeR and performs the adjustments needed for playback compatibility. It modifies essential files such as INDEX.bdmv, .mpls, .clpi, and .m2ts, ensuring they align with UHD-BD requirements.

This process helps avoid player errors and delivers smoother playback on compatible devices.

Adjustments for UHD-BD compliance

In addition to structural fixes, the tool sets important HDR metadata flags, including BT.2020 and BD.709, so the video is recognized correctly by hardware players. It can also convert HEVC files into Blu-Ray disk structures.

However, HEVC files created after modification are not intended to be played directly on UHD-BD hardware, as they are formatted specifically for inclusion in a compliant Blu-Ray structure. This is by design, so users should be aware of it when preparing their projects.

Although the application is lightweight and portable, it performs file-level changes that would otherwise require advanced editing skills or professional authoring software.

By running TSM2UHD after multiplexing your HEVC and audio streams with tsMuxeR, you can prepare the final folder for burning or direct playback.

Use cases and limitations

This tool is best suited for users who need to perform small but critical structural modifications. Many hobbyists have reported success in producing UHD-BD discs that play correctly on standalone players.

However, any issues present in the original tsMuxeR output, such as audio sync problems or incorrect color encoding, will remain and must be addressed separately.

Pros

• Makes tsMuxeR output compatible with UHD-BD players
• Adds necessary HDR metadata flags for correct playback recognition
• Performs HEVC-to-Blu-Ray structure conversion
• Portable and easy to use with a focused purpose
• Reduces the need for additional complex authoring tools

Cons

• Not a full authoring tool and limited to modifying existing Blu-Ray structures
• HEVC files created after modification are not directly compatible with UHD-BD playback
• May not correct problems caused by issues in the original muxed files

FAQs

1. Can this tool create a UHD-BD structure from any video?
No. It modifies a Blu-Ray folder generated by tsMuxeR. Multiplexing must be done first.

2. Does it support HDR metadata?
Yes. It adds BT.2020 and BD.709 flags so video is recognized correctly on UHD-BD hardware.

3. Can the HEVC file produced after modification be played directly?
No. The HEVC file is formatted for Blu-Ray structure integration, not for direct playback.

Conclusion

TSM2UHD fills an important role for UHD Blu-Ray enthusiasts who want their tsMuxeR projects to be playable on standalone players. By performing targeted structural modifications, adding essential metadata, and converting HEVC files into compliant Blu-Ray structures, it bridges the gap between basic muxing and full professional authoring.

While it is not a replacement for full-featured authoring software, it remains a practical and effective solution for improving UHD-BD playback compatibility.
