What is Clip Caption Kit?
Clip Caption Kit handles the subtitle delivery workflow when one long video becomes many clips. It reads the master SRT and clip ranges, resets each retained caption against its clip’s start time, and packages the resulting SRT and TXT files with a manifest. The video itself is not uploaded. Read the step-by-step workflow guide for the complete handoff.
What is a clip-relative subtitle file? A clip-relative subtitle file uses the start of a video clip as time zero. Each retained cue is re-timed relative to that point; the first cue may begin later than 00:00:00,000. You create one by subtracting the clip's start time from every caption timestamp in the master SRT. On this site, “clip-relative subtitle”, “re-timed subtitle”, “reset to 00:00” and “zero-based caption timing” all mean the same thing.
Example: 03:45.500 − 03:42.000 = 00:03.500.

How does the subtitle delivery workflow work?
Define clips in a CSV timeline
Upload a CSV with name, start and end for every clip — or download the example files below and try those first.
Review boundaries and export
Preview each clip and choose how captions crossing its boundaries are handled. Then export re-timed SRT and TXT files plus a manifest in one ZIP.
Want to try it without your own files?
Download the example master SRT and clip CSV, load them in the splitter above, and see the whole delivery package without using your own files.
Every clip leaves with the same files.
Each ZIP follows the same delivery structure: one clip-relative SRT and one plain-text TXT per clip, plus manifest.csv for ranges, caption counts, boundary policy and warnings. The clip start is time zero; the first retained cue may begin later.
Clip-relative SRT
Cues are re-timed so 00:00:00,000 is the first frame of the clip. The file drops into the edit with no manual offset.
Plain-text TXT
The same captions with timecodes removed, ready for scripts, social copy, QC sheets and translation handoffs.
manifest.csv
One row per clip with start, end, duration, caption count, boundary policy and warning count, so the package is auditable without opening a single file.
episode-042-shorts-deliverables.zip ├── srt/ one SRT per clip, re-timed from 00:00 ├── txt/ one plain-text transcript per clip └── manifest.csv range, duration, caption count, policy
Timecodes accept HH:MM:SS.mmm and HH:MM:SS,mmm in the timeline CSV. Captions that cross a clip boundary are either trimmed to the boundary or excluded, and the choice is written into manifest.csv so the handoff stays reproducible.
Built for the teams that cut one video into many.

Free SRT splitting tools.
One range or one split point — no CSV needed. When the job grows to a whole clip list, the batch splitter takes over.
Split SRT by TimestampUpload an SRT, enter a start and end time, and export that subtitle segment. Optionally reset timestamps to 00:00 and choose how boundary captions are handled.Split an SRT File OnlineSplit an SRT file at an exact timestamp. Keep master timing or reset the second part, choose how boundary captions are handled, and download both parts.
Manual subtitle delivery workflow vs Clip Caption Kit
