What Is Video Remuxing?
Understand the difference between remuxing and transcoding, why remuxing can be fast, and when it cannot replace a real conversion.
What matters
Remuxing changes the container while copying compatible elementary streams.
Because the compressed video and audio are not decoded and re-encoded, there is no new generation of codec loss.
Step-by-step
- Step 1Remuxing only works when the destination container supports the existing streams and metadata needed for the workflow.
- Step 2If codecs or stream characteristics are incompatible, transcode instead.
Keep the workflow local
FastConvert is positioned as a local Windows media converter. The conversion itself is performed through FFmpeg on the machine rather than sending the media to a browser upload service.
