Correct words in a clip’s transcript — typically misspellings or names the speech-to-text got wrong (for example Kaz Schwarz → Cozz). Corrections flow into the clip’s subtitles. Read the transcript first to find what you want to change, then send a patch.

Transcript edits do not re-export the video. After patching, call POST /render to produce a clip with the corrected subtitles. The cached renderedUrl is cleared automatically on every patch.

Read the transcript

GET https://api.joinoverlap.com/clip-transcript?companyId={companyId}&clipId={clipId}

Returns the word-level transcript. Use it to locate the words to fix and to read their index and timestamps for precise targeting. Preserved transcripts also return wordId, sourceWordId, sentenceId, sourceSentenceId, sentenceStart, and sentenceEnd. Corrections publish a new working revision and preserve the original selection transcript. They do not request speech recognition again or infer new sentence edges from edited punctuation. Provider timing may include words whose start and end are identical. These records still carry word identity and sentence markers; keep them when editing the transcript rather than inventing a spoken duration or new sentence boundary.

Query Parameters

Parameter	Required	Description
`companyId`	Yes	Your Overlap company or organization identifier.
`clipId`	Yes	The clip id returned by `GET /workflow-results/{triggerId}`.

Also available at GET /companies/{companyId}/clips/{clipId}/transcript.

Response

{
  "clipId": "clip-id-from-results",
  "source": "wordTranscriptJSON",
  "wordCount": 312,
  "words": [
    { "index": 86, "word": "Kaz",     "start": 12.50, "end": 12.80, "speaker": 0, "isDeleted": false, "visible": true },
    { "index": 87, "word": "Schwarz", "start": 12.80, "end": 13.20, "speaker": 0, "isDeleted": false, "visible": true },
    { "index": 88, "word": "went",    "start": 13.45, "end": 13.70, "speaker": 0, "isDeleted": false, "visible": true }
  ]
}

Field	Type	Description
`index`	number	Stable position of the word in the transcript. Use it for `index` targeting.
`word`	string	The word text (includes punctuation).
`start` / `end`	number	Word timing in source-video seconds. Use these for time-range targeting.
`speaker`	number	Diarized speaker index (0-based), when available.
`isDeleted`	boolean	Whether the word has been removed from captions.
`visible`	boolean	Whether the word falls inside the clip’s currently visible region (see below).

Patch the transcript

PATCH https://api.joinoverlap.com/clip-transcript

Send one or more operations. Each operation targets a span of words and replaces it with the to phrase. There are three ways to target a span — pick whichever is most convenient:

Target by	Fields	Use when
Text	`from`, `to`	Fixing a known word/phrase everywhere it appears (best for spelling and names).
Time range	`start`, `end`, `to`	You know the seconds of the span (from the `GET` response).
Index	`index`, `to`	You want one specific word, by its `index` from the `GET` response.

{
  "companyId": "your-company-id",
  "clipId": "clip-id-from-results",
  "operations": [
    { "from": "Kaz Schwarz", "to": "Cozz" },
    { "start": 12.5, "end": 13.2, "to": "Cozz" },
    { "index": 86, "to": "Cozz" }
  ]
}

Operation fields

Field	Type	Notes
`to`	string	The replacement text. Required. (`replacement` is accepted as an alias.)
`from`	string	Text to match. Whole-word, case-insensitive by default. Replaces every occurrence. May be multiple words (e.g. `"Kaz Schwarz"`).
`matchCase`	boolean	Match `from` case-sensitively. Defaults to `false`.
`start` / `end`	number	Source-video seconds. Selects words overlapping the range. Use the timestamps from the `GET` response.
`index`	number	A single word’s `index` from the `GET` response.

A span is collapsed into the replacement: the first word in the span becomes the new text spanning the original span’s timing, and the rest of the span is removed from captions. Timing stays aligned to the audio, so the corrected text shows at the right moment.

Response

{
  "clipId": "clip-id-from-results",
  "status": "success",
  "applied": 3,
  "replaced": 4,
  "appliedToHiddenWords": 0,
  "warnings": [],
  "words": [ "...updated transcript..." ]
}

Field	Type	Description
`applied`	number	Operations processed.
`replaced`	number	Spans actually replaced (an operation that matched nothing counts as applied with 0 replacements).
`appliedToHiddenWords`	number	Replacements that landed on words outside the visible region (see below).
`warnings`	string[]	Non-fatal issues with individual operations.
`words`	object[]	The full updated transcript, in the same shape as the `GET` response.

Visible region vs extended region

A clip is transcribed from the full extended source, so the transcript can include words in the padding that aren’t shown in the current cut. The visible flag on each word tells you whether it currently renders:

Editing a visible word changes the subtitles as expected.
Editing a hidden word (outside the visible region) is saved, but it won’t appear unless the clip is extended in the studio to include that word. These show up as appliedToHiddenWords in the patch response.

For most spelling/name fixes you don’t need to think about this — text targeting (from/to) replaces every matching word regardless of region, and the timestamps returned by GET already account for it.

Errors

Code	Status	Meaning
`INVALID_OPERATIONS`	400	`operations` is missing/empty, or every operation was invalid.
`NO_TRANSCRIPT`	409	The clip has no transcript yet (it may still be generating).
`CLIP_NOT_FOUND`	404	No clip for that `companyId` / `clipId`.
`INVALID_API_KEY`	401	Missing or invalid API key.
