How to burn 4K MKV to UHD ISO with multiple audio tracks and multiple subtitles?


    Creating a 4K UHD Blu-ray ISO with multiple audio tracks and subtitles allows you to enjoy a rich multimedia experience akin to commercial discs. This setup supports various languages, catering to a global audience. In this article, we will introduce two 4K UHD authoring software options that enable you to produce a 4K UHD Blu-ray ISO with multiple audio tracks and subtitles, emulating the capabilities of commercial discs.

4K MKV movies downloaded from the Internet typically include multiple audio tracks and subtitles, often extracted from 4K Blu-ray discs. These 4K MKV files offer excellent image quality, featuring technologies such as HDR10 and Dolby Vision, as well as high-quality audio formats like DTS HD Master, TrueHD (Dolby Atmos), and Blu-ray PCM. The inclusion of multiple audio tracks and subtitles allows viewers from different countries and language backgrounds to enjoy the content seamlessly.


Want to convert your 4K MKVs to UHD Blu-ray? Want to watch movies on a big-screen TV? Looking to create a 4K Blu-ray ISO with multiple audio tracks and subtitles? While professional 4K UHD authoring software can fulfill these needs, they are often prohibitively expensive, costing thousands or even tens of thousands of dollars. Conversely, cheaper 4K UHD authoring software usually comes with significant limitations, such as a lack of support for menus, multiple audio tracks, and subtitles.


Don't worry, we have a solution. Today, we recommend Yuhan 4K UHD Creator, an affordable and powerful 4K UHD authoring software that meets almost all your 4K UHD creation needs. Additionally, we introduce TsMuxer, a free 4K UHD authoring software that supports multiple audio tracks and subtitles, and outputs to Blu-ray folders and ISOs.

Step 1: Add MKV file

Open TsMuxer and click the "Add" button in the upper right corner to add your files.

After adding the files, you can choose the desired audio tracks and subtitles in the Tracks section.



Step 2: Blu-ray settings

Click on the Blu-ray tab to access various Blu-ray settings. Here, you can configure chapters, either by setting a chapter at regular intervals (e.g., every fixed number of minutes) or by customizing them down to the millisecond.

Step 3: Split & cut

Click the "Split & Cut" tab to either cut the video or split the generated Blu-ray M2TS file. There are two splitting methods available: split by time and split by file size.


Step 4: Start creating

After completing all the settings, check the "Blu-ray ISO" option in the Output bar. Set the disc label and the ISO file name. Once these settings are configured, click the "Start muxing" button below. TsMuxer will begin processing, and because it operates in Passthrough mode, it runs very quickly, often finishing within ten minutes.
