SBV uses periods where SRT uses commas—one character breaks everything
YouTube's SBV format and the standard SRT subtitle format appear nearly identical at first glance. Both contain timestamps and captions. But a single character is the difference between working subtitles and silence: the millisecond separator. SBV timestamps use a period: 0:00:01.000. SRT demands a comma: 00:00:01,000. Most video players reject the wrong separator and fail to display captions.
Hours drop their leading zero in SBV; SRT always pads them
SBV omits the leading zero from hours to save space. A caption at one hour appears as 1:00:00.000 in SBV but must become 01:00:00,000 in SRT. The converter re-pads every timestamp and fixes the millisecond separator in one transformation.
A complete cue: before and after conversion
SBV input: 0:00:01.000,0:00:04.000 followed by the line Welcome to the show.
SRT output: First the cue number 1, then the time range 00:00:01,000 --> 00:00:04,000, then the text Welcome to the show.
Notice the transformation: cue numbering added (SRT requires sequential numbers), hours zero-padded (0→00), decimal point becomes comma, and the comma between timestamps becomes an arrow with spaces.
What does not survive conversion
This tool transforms timestamps and text only. Any HTML markup, CSS styling, positioning metadata, or cue identifiers in your SBV are stripped—SRT has no standard to represent them. Input is assumed UTF-8. Malformed timestamps cause errors rather than silent skipping. WebVTT can express positioning and styling that SRT cannot, though nothing in an SBV source will populate it — see SBV to VTT. To convert SRT back to SBV, use SRT to SBV.

Frequently asked questions
Common questions about the SBV to SRT Converter.
Why won't my downloaded YouTube SBV file play in my video player?
Most video players expect SRT or VTT format, not SBV. YouTube exports captions in SBV by default, but VLC, Windows Media Player, browsers, and most software don't understand it. Convert your SBV to SRT using this tool and the same captions will work everywhere.
What's the difference between SBV and SRT timestamps?
SBV timestamps use a period for milliseconds (0:00:01.000) and don't pad single-digit hours. SRT uses a comma (00:00:01,000) and always zero-pads hours to two digits. That single character—period versus comma—is why SRT players fail on SBV files. The time separator also changes to an arrow.
Does the converter preserve all my captions and timing?
Yes—every word and every timestamp from your SBV file is preserved exactly. The converter only changes the formatting: timestamps are re-formatted, hours are zero-padded, and cue numbers are added. Any styling metadata is dropped, but the captions themselves survive unchanged.
Can I convert YouTube captions to use in video editors like DaVinci Resolve?
Yes. Export your captions from YouTube as SBV, convert them to SRT here, then import the SRT file into your video editor. Most professional editing software supports SRT format natively. The timing and text stay exactly the same.
