Everything about adding TS subtitles
Can Sonix add subtitles to TS videos?
Yes! Upload your TS 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 TS 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 TS file play on my computer?
Some default media players lack the demuxers or codecs used in broadcast transport streams. Free players such as VLC open most .ts files, or the file can be remuxed to MP4 without re-encoding.
Do I need to join multiple .ts segments before transcribing?
Streaming captures often arrive as many short .ts segments, and combining them into one file first keeps the transcript in a single continuous document. Segments from the same stream can usually be concatenated without re-encoding.
