HEVC, AVC, and MPEG multiplexer and splitter

Optimize your file based workflow with this easy to use broadcast compliant multiplexing and splitting application.

Expert-Mux is a software tool that can multiplex one or two HEVC (H.265), AVC (H.264), or MPEG video streams with one or two MPEG, AC3, DTS, or AAC compressed audio streams or up to 8 PCM uncompressed audio streams (SMPTE-302m) into a Transport or Program stream. The tool can also split Transport, MXF, or Program streams into their elementary components.

Expert-Mux includes a rich set of user parameters that optimize multiplexing overhead to create the highest quality compressed video streams for use in broadcast, video on demand, or desktop systems.

Expert-Mux can automatically multiplex a large group of files via the Windows command line or via an easy to use Batch Control Dialog. Using the Windows command line, Expert-Mux is launched from a batch file and reads a parameter file that contains custom multiplex settings for each job. The batch mode provides a convenient way to work with other PixelTools products to encode video and audio clips and multiplex them with specific multiplexing parameters — automatically without operator intervention.

Check out this video to see how easy Expert-Mux is to use.

The Batch Control can accept elementary files via Drag and Drop, the file browser, or from a simple text file. Depressing the Run button causes all jobs in the batch window to be executed with any errors recorded in a log file.
