Transcribe
Generate SRT subtitle files + readable text from audio/video using ElevenLabs Scribe v2.
Quick Start
cd .claude/skills/transcribe/scripts
# Basic transcription (generates both SRT + readable .md)
npx ts-node transcribe.ts -i /path/to/video.mp4 -o /path/to/output.srt
# Specify language
npx ts-node transcribe.ts -i /path/to/video.mp4 -o /path/to/output.srt -l he
# Only readable text (skip SRT)
npx ts-node transcribe.ts -i /path/to/meeting.m4a -o /path/to/output.srt --no-srt
# Shorter timestamp intervals (every 2 minutes)
npx ts-node transcribe.ts -i /path/to/video.mp4 -o /path/to/output.srt --timestamp-interval 120
# Disable speaker diarization
npx ts-node transcribe.ts -i /path/to/video.mp4 -o /path/to/output.srt --no-speakers
Output Files
The script always generates:
.srt- Standard subtitle file (for embedding).md- Readable text with speakers + timestamps every ~5 min
Optional:
3. _transcript.json - Raw word-level data (with --json)

Language Codes
en- Englishhe- Hebrewar- Arabices- Spanishfr- Frenchde- Germanru- Russianzh- Chineseja- Japanese- (or omit for auto-detection)
Readable Text Format
The .md file includes:
- Header with filename, date, duration
- Speaker labels (דובר 1, דובר 2...) when diarization detects speaker changes
- Timestamps every ~5 minutes (configurable)
- Paragraphs broken naturally at sentence boundaries
Example:
# תמלול: meeting.m4a
**תאריך:** 27.1.2026
**משך:** 45:32
---
**דובר 1:**
שלום לכולם, אני רוצה להתחיל את הפגישה...
**דובר 2:**
בסדר, בוא נדבר על הנושא הראשון...
**[5:00]**
**דובר 1:**
עכשיו נעבור לחלק השני...
Translation
If target language differs from audio language:
- Transcribe first (get original language SRT)
- Read the SRT, translate each entry preserving timestamps
- Write translated SRT file
No API needed - translate directly.
Post-Transcription Refinement (Claude's Job)
After generating the raw SRT, always refine it semantically. The transcription API chunks by time intervals, not meaning - this creates awkward splits like:
1
00:00:00,500 --> 00:00:01,922
anything a human being can
2
00:00:02,002 --> 00:00:03,320
do, your Claude bot can
The word "do" belongs with the previous sentence! Always regroup by semantic meaning:
Refinement Rules
- Complete sentences/clauses together - Never split subject from verb, verb from object
- Move orphaned words - If a line starts with a word that completes the previous thought, merge it
- Punctuation guides splits - Periods, question marks, exclamations are natural break points
- Preserve parallel structure - Keep matching phrases together (e.g., "if X can do it, Y can do it")
- Emphasis stays standalone - Repeated words for emphasis ("Anything. Anything!") get their own line
- Action chains can split - Lists of actions can be separate lines if they're complete thoughts
Refinement Process
- Read the raw SRT
- Concatenate all text to see full content
- Identify natural sentence/clause boundaries
- Redistribute words into semantic groups
- Adjust timestamps: line starts at first word's time, ends at last word's time + small buffer
- Write refined SRT
Example Before/After
Before (raw):
1
00:00:00,500 --> 00:00:01,922
anything a human being can
2
00:00:02,002 --> 00:00:03,320
do, your Claude bot can
3
00:00:03,341 --> 00:00:06,282
do. Anything. Anything!
After (refined):
1
00:00:00,500 --> 00:00:02,100
anything a human being can do,
2
00:00:02,100 --> 00:00:03,500
your Claude bot can do.
3
00:00:03,600 --> 00:00:06,100
Anything. Anything!
Always apply this refinement after transcription. The user expects semantically coherent subtitles.
