​
Overview

The Video Transcription API generates accurate transcriptions and subtitles for your video or audio files. It supports over 20 languages and can automatically detect speech, convert it to text, and provide timing information for subtitle creation. You can also provide your own transcript or request AI-generated highlights from the transcription. This endpoint processes files asynchronously and returns a job ID that you can use to track the transcription status. Once complete, you will receive the full transcript with precise timing information in formats suitable for SRT, VTT, or JSON subtitle files.

​

Response

​
Success Response

When the transcription request is successfully submitted, a job is created and a job ID is returned:
​
success
boolean
Indicates whether the request was successful
​
data
object
Contains the transcription job information
​
jobId
string
Unique identifier for the transcription job. Use this to track the job status and retrieve results via the Get Transcription Job by ID endpoint.
{
    "data": {
        "jobId": "cbbc5305-3c1c-46f0-bdde-468e5ecd763f"

Common Use Cases

​
1. Basic Video Transcription

Generate a transcript for a video file in English: 
import requests

url = "https://api.pictory.ai/pictoryapis/v2/transcription"
headers = {
    "Authorization": "YOUR_API_KEY",
    "Content-Type": "application/json"

response = requests.post(url, json=payload, headers=headers)
data = response.json()

if data.get("success"):
    print(f"Job ID: {data['data']['jobId']}")
    print("You will receive the transcript at your webhook URL when processing is complete")

​
2. Multi-Language Transcription

Transcribe content in different languages: 
import requests

def transcribe_video(video_url, language_code, webhook_url):
    url = "https://api.pictory.ai/pictoryapis/v2/transcription"
    headers = {
        "Authorization": "YOUR_API_KEY",
        "Content-Type": "application/json"
    }

    payload = {
        "fileUrl": video_url,
        "mediaType": "video",
        "language": language_code,
        "webhook": webhook_url
    }

    response = requests.post(url, json=payload, headers=headers)
    return response.json()

# Transcribe videos in different languages

    ("https://example.com/english-video.mp4", "en-US"),
    ("https://example.com/spanish-video.mp4", "es-ES"),
    ("https://example.com/japanese-video.mp4", "ja-JP")
]

for video_url, language in videos:
    result = transcribe_video(video_url, language, "https://your-domain.com/webhooks/transcription")
    if result.get("success"):
        print(f"Started transcription for {language}: {result['data']['jobId']}")

​
3. Audio File Transcription

5. Batch Processing Multiple Videos

Process multiple videos and track their job IDs: 
import requests
import time

def start_transcription(file_url, language):
    url = "https://api.pictory.ai/pictoryapis/v2/transcription"
    headers = {
        "Authorization": "YOUR_API_KEY",
        "Content-Type": "application/json"
    }

    payload = {
        "fileUrl": file_url,
        "mediaType": "video",
        "language": language,
        "webhook": "https://your-domain.com/webhooks/transcription"
    }

    response = requests.post(url, json=payload, headers=headers)
    return response.json()

# List of videos to transcribe
videos_to_process = [
    {"url": "https://example.com/video1.mp4", "language": "en-US", "title": "Introduction"},
    {"url": "https://example.com/video2.mp4", "language": "en-US", "title": "Tutorial Part 1"},
    {"url": "https://example.com/video3.mp4", "language": "es-ES", "title": "Spanish Version"}
]

job_tracker = []

for video in videos_to_process:
    result = start_transcription(video["url"], video["language"])

    if result.get("success"):
        job_info = {
            "title": video["title"],
            "jobId": result["data"]["jobId"],
            "language": video["language"]
        }
        job_tracker.append(job_info)
        print(f"Started: {video['title']} - Job ID: {result['data']['jobId']}")
        time.sleep(1)  # Rate limiting
    else:
        print(f"Failed to start: {video['title']}")

# Save job IDs for tracking
print(f"\nTotal jobs started: {len(job_tracker)}")
for job in job_tracker:
    print(f"  {job['title']}: {job['jobId']}")

​
Best Practices

  1. Webhook Configuration: Ensure your webhook endpoint is configured to handle POST requests and can process the transcript payload. The webhook should return a 200 status code to acknowledge receipt.
  2. File Accessibility: Make sure your video/audio files are publicly accessible via HTTPS. The transcription service must be able to download the file from the provided URL.
  3. Language Selection: Choose the correct language code for best transcription accuracy. Using the wrong language will result in poor quality transcripts.
  4. File Format: Use common formats like MP4, MP3, or WAV for best results. Ensure audio quality is clear for accurate transcription.
  5. Processing Time: Transcription is an asynchronous process. Processing time varies based on file length and complexity. Use the webhook to receive results rather than polling.
  6. Custom Transcripts: When providing custom transcripts, ensure timing information is accurate with start and end times in seconds. This enables proper synchronization.
  7. Rate Limiting: Implement appropriate delays between batch requests to avoid rate limiting. Process videos sequentially with small delays between API calls.
  8. Error Handling: Implement proper error handling for failed transcriptions. Check the webhook payload for error messages and retry if necessary.
