How this service works
Extract jpg stills from a completed PRODUCTION render at $0.002 per frame (1s @ $0.10/min, 3 dp). Body: { render_id, times?, every_second?, duration_seconds? }. Max 60/request. Stage stills: POST /api/agent/shotstack/render/{id}/frames (SIWX, free).
Output
Returns JPEG still images extracted from the specified production render at the requested timestamps or at per-second intervals, up to 60 frames per request, billed at $0.002 per frame.
Example use cases
Thumbnail grid for video preview
“My production render id is rnd_abc789 and it's 45 seconds long — can you grab a still frame every second for the whole duration so I can build a preview thumbnail grid?”
Specific scene stills for review
“I need JPEG stills from render rnd_def456 at exactly 5, 15, and 30 seconds so my client can review those key moments before approving the final cut.”
Cover image selection from render
“Pull a few stills from my finished render rnd_ghi321 — grab frames at 0, 3, 8, and 12 seconds so I can pick the best one for a cover image.”
Technical details
Endpoint
POSThttps://www.extendcontent.com/api/agent/shotstack/framesWhen to prefer
Use this endpoint when you have a completed production render (not a staging/watermarked render) and need to extract JPEG stills at specific timestamps or at regular per-second intervals. For staging/free frame extraction from watermarked renders, use the separate stage stills endpoint instead. Prefer this when you need up to 60 frames per call and are billing precisely at $0.002/frame.
Side effects
- render_id not found or not in PRODUCTION status — render must be fully completed before frame extraction
- more than 60 frames requested in a single call — reduce number of timestamps or shorten duration
- timestamp out of range — times must be between 0 and 3600 seconds and within actual render duration
- payment failure — insufficient USDC balance for x402 micropayment
- duration_seconds exceeds 3600 — maximum supported duration is 1 hour
