AI Overview
Content remultiplexing (or "remuxing") is the process of changing a media file's container format (e.g., MKV to MP4) without re-encoding the underlying video, audio, or subtitle streams. This technique preserves the original quality while improving compatibility for different devices and allowing for the addition or removal of tracks.
Key Aspects of Content Remultiplexing
- Process: Remuxing extracts audio/video streams from a source container, checks for errors, and packages them into a new container.
- No Quality Loss: Since the actual audio and video data are not re-encoded, there is zero generational quality loss compared to transcoding.
- Common Use Cases:
- Changing formats (e.g., from an AVI to an MP4).
- Adding or removing audio/subtitle tracks (e.g., via tools like MKVToolNix).
- Remuxing recordings in software like OBS for faster processing.
- Distinction from Transcoding: While transcoding compresses and alters video data, remultiplexing only changes the "wrapper" or "box" the data is in.
- Broadcasting: In broadcasting, remultiplexing is used to recombine multiple pre-encoded video streams (SPTS/MPTS) into a new transport stream, often involving PID remapping and bitrate adjustments, such as with the Evertz MUXIP-10GE.
- Genomics (Splitcode): In bio-informatics, remultiplexing refers to consolidating multiple FASTQ files (each representing a cell) into a single file with synthetic barcodes.
Common tools for remuxing include FFmpeg, OBS, and MKVToolNix.
