What changes when you convert MTS to Opus
This extracts the audio and discards the video entirely. The soundtrack inside a MTS file is typically AC-3, and it is re-encoded to Opus on the way out.
Expect a much smaller file. Video accounts for most of the bytes, so about 169 MB per minute becomes roughly 1 MB per minute of Opus.
When a video holds several audio tracks, the main one is extracted; alternate language tracks are not merged into the result.
About MTS to Opus Conversion
Extracting Opus audio from a MTS video pulls the soundtrack out of the AVCHD container and writes it as a standalone Ogg file. The video stream, which holds most of the data, is discarded.
Developed by Sony / Panasonic in 2006, MTS stores audio using H.264. That codec choice sets the upper bound on what any conversion can preserve.
Opus, from Xiph.Org / IETF and dating to 2012, uses Opus and plays natively on 2 of the six platform categories we track. That combination is usually why people convert into it.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
