Everything about adding MXF subtitles
Can Sonix add subtitles to MXF videos?
Yes! Upload your MXF 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 MXF 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.
Why won't my MXF file play in a regular media player?
MXF is a professional container, and consumer media players often lack the codecs it wraps, such as XDCAM or AVC-Intra. VLC or a professional editing application like Premiere Pro or Avid Media Composer can usually open it.
Do I need to convert MXF to MP4 before transcribing?
Usually not. You can upload the MXF file directly for transcription; conversion to MP4 is only needed if a downstream tool in your workflow does not support the MXF container.
