CSV format and example
Three columns are required. Every row becomes one output file pair, named after the clip.
name,start,end intro,00:00:15.000,00:00:45.000 clip-01,00:03:42.000,00:04:18.000 clip-02,00:08:14.000,00:09:02.000
Download the example clip CSV or the blank template, and the example master SRT to run a full export without your own files.
How batch SRT splitting works
- Upload the master subtitles exported for the full-length source video, podcast or webinar.
- Upload the clip timeline CSV. Every row is validated with its row number and original line shown for anything that needs fixing.
- Review each clip: caption count, boundary warnings, the safe filename actually used, and the first and last caption. Then export one ZIP.
| Manual workflow | Clip Caption Kit |
|---|---|
| Search the master SRT for every range | Read all ranges from one CSV |
| Copy captions into separate files | Generate all clip files together |
| Subtract each clip start time by hand | Re-time every caption automatically |
| Renumber and rename files manually | Consistent numbering and filenames |
| Repeat for every revision | Re-run the same project deterministically |
What files are included in the ZIP
Each clip leaves with the same pair of files, and the manifest makes the package auditable without opening a single one:
episode-042-shorts-deliverables.zip ├── srt/ │ ├── opening-highlight.srt │ ├── clean-excerpt.srt │ └── silent-b-roll.srt ├── txt/ │ ├── opening-highlight.txt │ ├── clean-excerpt.txt │ └── silent-b-roll.txt └── manifest.csv
How clip-relative timestamps are calculated
For every caption inside a clip, the clip start time is subtracted in integer milliseconds — never floating point — and the result is written back in standard SRT format:
Source cue: 00:03:45,500 --> 00:03:48,000 Clip starts: 00:03:42,000 Clip-relative cue: 00:00:03,500 --> 00:00:06,000
Captions are renumbered from 1 in every file, and no timestamp can be negative, so each file is valid on its own.
Boundary caption handling
A caption that crosses a clip start or end can be trimmed to the boundary (the default) or excluded entirely. The policy is chosen per clip in the review step and recorded in manifest.csv, so a revision months later reproduces the same result.
The full walkthrough — including the manual method and the timestamp formulas — is in How to Split One Master SRT for Multiple Video Clips, and the scenario page explains what editors and podcast teams use it for on the subtitles for video clips page.
