Blu-ray & AVCHD Authoring

Create fully compliant Blu-ray Disc (BDMV) and AVCHD folder structures. Perfect for playing remuxed movies directly on hardware media players, PlayStation, or burning to disc.

Dolby Vision Profile 7 & HDR

Advanced support for dual-layer Dolby Vision (Base Layer + Enhancement Layer). Handle HDR10, HDR10+, and dynamic metadata seamlessly across TS, M2TS, and Matroska outputs.

Passthrough Lossless Audio

Full support for high-bitrate surround audio including Dolby TrueHD (with AC3 core), Dolby Atmos, DTS-HD Master Audio, and DTS:X IMAX without downmixing or compression.

PGS Subtitle & Track Controls

Convert text SRT subtitles directly into Blu-ray PGS graphic streams. Shift audio and subtitle timing for perfect lip-syncing and set language flags manually.

Splitting, Cutting & Joining

Split output files by specific time durations or file size limits (e.g., 4.7GB for DVD-R or 25GB for BD-R). Easily join multiple video segments seamlessly.

Frequently Asked Questions

Got questions about tsMuxeR? Find quick answers regarding remuxing, quality preservation, and formats.

Does tsMuxeR reduce video or audio quality during remuxing? +

No, absolutely not. tsMuxeR operates strictly as a stream multiplexer (Remux tool). It extracts and recombines raw video and audio bitstreams without performing any re-encoding or compression. Your media retains 100% of its original picture and sound quality.

How does tsMuxeR handle 4K UHD Dolby Vision Profile 7? +

tsMuxeR is one of the very few remuxing tools that natively preserves dual-layer Dolby Vision Profile 7 (Base Layer + Enhancement Layer / RPU metadata). When outputting to M2TS or TS containers, it ensures high-end hardware media players receive the full dual-layer signal for optimal HDR playback.

Can I convert text subtitles (SRT) into Blu-ray PGS graphic subtitles? +

Yes. tsMuxeR includes a built-in subtitle renderer that automatically parses text SRT files and generates native Blu-ray Presentation Graphic Stream (PGS) subtitles. You can customize font family, text size, color, border width, and vertical positioning.

What is the difference between tsMuxeR and MKVToolNix? +

While MKVToolNix focuses exclusively on the Matroska (.mkv) container format, tsMuxeR specializes in Transport Streams (.ts / .m2ts) and full Blu-ray / AVCHD disc authoring (BDMV structure). tsMuxeR is ideal for hardware players and optical media, while MKVToolNix is suited for general software media centers.

Is tsMuxeR free and safe to use? +

Yes, tsMuxeR is 100% free, open-source software licensed under Apache-2.0. It contains no spyware, adware, or background telemetry, and runs as a standalone portable application without requiring complex system installation.
