Free Online SBV to SRT Converter
Our SBV to SRT converter rewrites SubViewer subtitle entries into SubRip format, the de facto standard accepted by virtually every media player, smart TV, and video editor. The tool splits each SBV single-line timestamp pair (start,end) into the two-line SRT arrow notation (start --> end), pads the hour field from one digit to two, changes the millisecond separator from a period to a comma, and prepends a sequence number to every cue. All subtitle text and timing values are preserved exactly. The entire conversion runs locally in your browser.
Input Format
SBVSubViewer (SBV) is a lightweight subtitle format popularized by subtitle repositories like SubDl and OpenSubtures. Each entry places both timestamps on a single line using the pattern 0:00:01.234,0:00:04.567 (start and end separated by a comma, hours not zero-padded, milliseconds preceded by a period). There are no sequence numbers and no file header. The subtitle text follows immediately below. SBV sometimes uses bracket-style tags such as [br] for line breaks and [i] for italics, but the format has no standardized styling system.
Output Format
SRTSRT (SubRip) is the most widely supported subtitle format in existence. Each entry consists of a sequential index number, a timestamp line in HH:MM:SS,mmm --> HH:MM:SS,mmm format (note the comma before milliseconds and the dash-arrow separating start and end), and one or more lines of subtitle text. SRT files are plain text with .srt extension and are recognized by every desktop player (VLC, MPC-HC, MPV), every smart TV brand, mobile video apps, and professional editing software.

Why Convert?
Format Differences
Common Use Cases
Smart TV Playback
Convert SBV subtitles downloaded from SubDl or OpenSubtitles so they display on Samsung, LG, Roku, Fire TV, and Apple TV, all of which only read SRT.
Video Editing Import
Load SubViewer files into Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro, which accept SRT on the timeline but do not parse SBV.
Media Server Library
Add subtitles to your Plex, Emby, or Jellyfin library. These servers auto-detect .srt files alongside video but ignore .sbv.
Mobile Video
Ensure subtitles work in iOS and Android video apps like Infuse, nPlayer, and MX Player by converting SBV to the universally supported SRT.
Encoding Pipelines
Feed subtitles into FFmpeg, HandBrake, or MKVToolNix workflows that hardcode or mux subtitles, all of which expect SRT input.
Subtitle Standardization
Normalize a mixed library of SBV, VTT, and SRT files into a single consistent SRT collection for easier management.
Related Formats
SBV (SubViewer)
The input format: comma-separated timestamps on one line, no sequence numbers, popular on subtitle download sites.
VTT (WebVTT)
The web video alternative: adds a WEBVTT header and uses period-separated milliseconds. Choose VTT if your target is HTML5 video or YouTube.
ASS (Advanced SubStation Alpha)
The styled alternative: supports fonts, colors, and positioning. Choose ASS if you need to add visual styling to SubViewer text.
Frequently Asked Questions
SBV uses a single line with both timestamps comma-separated (0:00:01.234,0:00:04.567). The converter splits this into the SRT arrow notation (00:00:01,234 --> 00:00:04,567), pads the hour to two digits, and replaces the millisecond period with a comma.
These tags are removed during conversion because SRT has no standardized bracket-tag system. The line breaks they represented are preserved as actual newlines in the subtitle text, and italic intent is lost (SRT does not support inline italics natively).
SBV files are most commonly downloaded from subtitle repositories like SubDl, OpenSubtitles, and some regional subtitle portals. They are less common than SRT or VTT, which is why converting to SRT ensures compatibility.
Yes. SRT requires every entry to begin with a sequential integer (1, 2, 3, ...). SBV does not use sequence numbers, so the converter generates them automatically and in order.
SubViewer places both timestamps on a single line separated by a comma, which is compact but non-standard. SRT puts them on separate lines joined by the --> arrow, which is the format every parser expects. The converter handles this structural difference automatically.
