Create Separate SRT Files for Multiple Video Clips

The problem after the cut

The edit is finished; the captions are not. The master SRT is timed against the full-length source, so a clip that starts 3:42 into the recording expects its first caption at 00:00, not at 3:42. Doing this by hand means finding every caption inside the range, copying it into a new file, subtracting the clip start from both timestamps, renumbering the cues and naming the file — repeated for every clip, and again after every revision.

The workflow

1. Export one SRT for the whole source. Keep it untouched — it stays the single source of truth for every clip.
2. List the clips in a CSV. Three columns: name,start,end. Copy the in/out points straight from your timeline.
3. Run the batch splitter. Every row is validated with its row number; captions that cross a boundary are trimmed or excluded per clip.
4. Deliver the ZIP. One SRT and TXT per clip under srt/ and txt/, plus a manifest that records range, caption count and policy.

Try it with the example master SRT and example clip CSV on the batch SRT splitter — no sign-up needed to load and review them.

Clip-relative time, in one line

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

Clip-relative time = source cue time − clip start time, computed in whole milliseconds. Because the same master SRT is reused for every clip, two clips can never disagree with each other.

Who this is for

• Freelance editors delivering interview or podcast cuts with 10–50 clips per project.
• Short-form studios shipping daily clip batches for several clients who need consistent filenames.
• Podcast teams repurposing one episode transcript into Shorts, Reels and TikToks.
• Course producers splitting a long recording into lessons that each start at 00:00.
• Content marketing teams where the person cutting the video is not the person who made the captions.

Revisions are the real cost

The first export is rarely the last: a clip moves 4 seconds, a client asks for a different opening, one range turns out to be silent. When the timeline lives in a CSV, a revision is a one-row edit and a re-run — not twenty files reopened by hand. The master SRT guide walks through that loop end to end.
