Frequently Asked Questions
Embedded subtitle tracks are not carried over in this conversion. Extract subtitles separately if needed.
The conversion outputs a single audio track. If your MKV has multiple audio streams, the first one is used.
The tool uses CRF 23, which produces visually transparent quality. Any difference from the original is imperceptible for most content.
