Generate AD Video

Pick one of the two simple flows below to generate audio description video.

Already uploaded media or using the signed upload flow? Generate with media_id. See Large Local File Upload or API Reference.

1. Using a Video from public URL

Upload from a public URL and generate in one step.

curl -X POST https://api.viddyscribe.com/enterprise/api/generate_ad_video \
  -H "X-API-Key: vsk_your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "input": {
      "type": "url",
      "url": "https://example.com/video.mp4"
    },
    "generation_config": {
      "language": "en-US",
      "voice": "Achernar",
      "ad_type": "extended_ad",
      "format": "vtt",
      "custom_instructions": "Keep descriptions concise and focus on on-screen text."
    }
  }'

Response:

{
  "job_id": "task_abc123xyz",
  "status": "queued",
  "media_id": "550e8400-e29b-41d4-a716-446655440000"
}

Use the job_id to poll get_results for completion.

2. Using a Video from local file

Upload a local file and generate in one step.

Direct multipart upload supports local files up to 32 MB. For larger local files, see Large Local File Upload.

curl -X POST https://api.viddyscribe.com/enterprise/api/generate_ad_video \
  -H "X-API-Key: vsk_your_api_key_here" \
  -F 'input={"type": "file"}' \
  -F "file=@video.mp4" \
  -F 'generation_config={"language": "en-US", "voice": "Achernar", "ad_type": "extended_ad", "format": "vtt", "custom_instructions": "Keep descriptions concise and focus on on-screen text."}'

Response:

{
  "job_id": "task_abc123xyz",
  "status": "queued",
  "media_id": "660f9511-f30c-52e5-b827-557766551111"
}

Use the job_id to poll get_results for completion. On success, video_signed_url contains the link to the generated video.

Tips

The default output format is vtt.
Choose standard_ad or extended_ad based on your timing and detail needs. See Standard AD vs Extended AD.
Use custom_instructions to guide the AI’s description style (e.g. tone, focus, or length).
Set read_all_onscreen_text: true for educational, government, or news content to force the AI to read slides, lower thirds, and on-screen labels verbatim (only applies when ad_type is extended_ad).

Retrieve Results

Use the job_id from the previous step to fetch results:

curl -X GET "https://api.viddyscribe.com/enterprise/api/get_results?job_id=TASK_ID" \
  -H "X-API-Key: vsk_your_api_key_here"

Example successful response for video jobs (with format: "vtt"):

{
  "job_id": "task_abc123xyz",
  "status": "done",
  "media_id": "550e8400-e29b-41d4-a716-446655440000",
  "video_signed_url": "https://storage.googleapis.com/bucket/path/to/video.mp4?X-Goog-Signature=...",
  "output": {
    "format": "vtt",
    "content": "WEBVTT\n\n1\n00:00:00.500 --> 00:00:03.100\nA woman in a yellow top sits at a desk with a laptop.\n\n2\n00:00:03.200 --> 00:00:05.900\nShe looks at the camera and smiles.\n"
