Everything about adding M2V subtitles
Can Sonix add subtitles to M2V videos?
Yes! Upload your M2V video, and Sonix will transcribe it and let you add professional subtitles with customizable styling.
Can I burn subtitles into the video?
Yes! Sonix can permanently embed (burn-in) subtitles into your M2V video with your choice of fonts, colors, and positioning.
What subtitle styles are available?
Customize fonts, colors, background boxes, positioning (top, center, bottom), and more for your burned-in subtitles.
Can I download subtitle files separately?
Yes! Export subtitles as SRT, VTT, or other formats to use with YouTube, Vimeo, or your video editor.
Can I translate subtitles to other languages?
Absolutely! Sonix can translate your subtitles into 55+ languages for multilingual videos.
How do I split subtitles correctly?
Sonix offers auto-split options for max characters per line, lines per caption, and max duration. Fine-tune manually if needed.
Can I convert M2V files to text?
Usually not directly, because most M2V files are video-only and contain no audio track. Upload the matching audio file — often a WAV, AIFF, or M2A saved alongside the M2V — then transcribe, edit, and export the text.
Why doesn't my M2V file have any sound?
M2V is an MPEG-2 video elementary stream, so the audio is stored in a separate file until the two are multiplexed during DVD or broadcast authoring. Look for a companion audio file with the same name to find the sound.
How do I create subtitles for an M2V video?
Transcribe the separate audio track that accompanies the M2V: upload the audio, review the transcript in the editor, and export it as an SRT or VTT subtitle file to mux with the video.

Trusted by video creators
I need to produce very accurate transcripts and the initial transcripts Sonix produces are much better than competitors (I've used many others).
Impressed at how seamless Sonix makes editing transcripts. This is so much easier and more enjoyable than manually writing an entire transcript myself.
