# case.dev Transcription

Audio and video transcription with speaker diarization, ideal for depositions, hearings, and recorded proceedings. Supports MP3, WAV, M4A, FLAC, OGG, WEBM, and MP4 up to 5GB.

Requires the `casedev` CLI. See `setup` skill for installation and auth.

## Start a Transcription

The source file must be in a vault:

```bash
casedev transcribe run --vault VAULT_ID --object OBJECT_ID --json
```

Flags: `--speaker-labels` (diarization), `--speakers-expected N`, `--language`, `--format`, `--auto-highlights`.

## Check Status

```bash
casedev transcribe status TRANSCRIPTION_ID --json
```

Statuses: `queued` -> `processing` -> `completed` or `failed`.

## Get Result

```bash
casedev transcribe result TRANSCRIPTION_ID --json
```

Fetches transcript text. Fails if the job is not yet completed.

## Watch Until Complete

```bash
casedev transcribe watch TRANSCRIPTION_ID --json
```

Flags: `--interval` (default: 3s), `--timeout` (default: 900s).

## Common Workflow

```bash
# 1. Upload to vault
casedev vault object upload ./deposition-recording.mp3 --vault VAULT_ID --json

# 2. Start transcription with speaker labels
casedev transcribe run --vault VAULT_ID --object OBJECT_ID --speaker-labels --speakers-expected 4 --json

# 3. Watch until complete
casedev transcribe watch TRANSCRIPTION_ID --json
```

## Troubleshooting

**"Invalid file type for transcribe"**: Only audio/video MIME types accepted. Check with `casedev vault object list`.

**Transcription failed**: Check `casedev transcribe status TRANSCRIPTION_ID --json` for error details. Common causes: corrupted file, unsupported codec, file too large.

**Long audio (2+ hours)**: Increase timeout with `--timeout 3600`.
