About This Tool

Converts a plain text transcript into a standards-compliant SubRip (SRT) file ready for video captions.
It segments the input into subtitle blocks, applies a strict index sequence, wraps lines to fit the target character limit, and formats timestamps as 00:00:00,000 --> 00:00:xx,xxx. The tool supports UTF-8 text and preserves non-Latin characters, punctuation, and line breaks where appropriate.
Two timing modes are available: auto timing distributes time across blocks using a per-block duration you specify, while manual timing accepts user-provided hints for start/end times. This makes it suitable for quick transcripts and for more precise captioning when syncing to existing video edits.
Who benefits: video editors, podcasters, e-learning teams, and content creators seeking consistent, publication-ready captions without manual SRT crafting. Unique value includes strict adherence to the SRT format, robust handling of wrapping, language-aware processing, and straightforward export flow. It reduces manual editing time, improves accessibility, and streamlines publishing pipelines.
Core features include block segmentation by blank lines or sentence boundaries, configurable max_chars_per_line, UTF-8 support, error checks for empty input, and optional export to VTT if needed. The tool operates entirely on text input and does not access media files, ensuring privacy and fast turnaround.

Frequently Asked Questions

Find Quick Answers

What formats are produced by the tool?
The default output is a standard SRT file encoded in UTF-8. An optional WebVTT export can be enabled to support web video players; SRT remains the primary, broadly supported format.
How does auto timing work?
In auto timing, each subtitle block is assigned a duration from per_block_duration_sec. Times are sequential and non overlapping. If the last block would exceed a maximum, timings clamp to a reasonable end. Users can switch to manual timing for precise synchronization.
How is text encoding handled?
All text is treated as UTF-8. Non-Latin characters are preserved exactly as input. No font or styling is embedded; the output relies on the video player to render appropriate fonts.
Can I customize line length?
Yes. The max_chars_per_line parameter controls wrapping. If a line exceeds this limit, the text is wrapped across additional lines and may create additional subtitle blocks to maintain readability.
