Step 5 — Export & Publish

All cells are filled from Step 4. Now you turn the vidsheet into a final MP4 and ship it.

The three sub-steps

1. Render          — composite all layers into one video
2. Poll            — wait for the render pipeline to finish
3. Download / Publish

Render the final video

curl -X POST "https://api.gen.pro/v1/autocontentengine/$ENGINE_ID/cells/$FINAL_VIDEO_CELL_ID/render?agent_id=$AGENT_ID" \
  -H "X-API-Key: $GEN_API_KEY"

Returns a generation_id pointing at the render job. Renders are async — poll:

curl "https://api.gen.pro/v1/generations/$GEN_ID" \
  -H "X-API-Key: $GEN_API_KEY"

Status flow:

pending → processing → completed | failed

On completed, output_resources[0].url is the CDN URL for the final MP4.

Download the MP4

curl -L -o final_video.mp4 "https://cdn.gen.pro/outputs/render_xyz.mp4"

CDN URLs are public — no auth required to download. See Download the Video for streaming / signed-URL patterns and handling.

Publish to social

Currently TikTok is fully supported (Instagram / YouTube coming):

curl -X POST "https://api.gen.pro/v1/user_jobs?agent_id=$AGENT_ID" \
  -H "X-API-Key: $GEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "user_job_type": "publish_content",
    "data": "{\"platform\":\"tiktok\",\"media_url\":\"https://cdn.gen.pro/outputs/render_xyz.mp4\",\"description\":\"The $2 taco at 2am #streetfood #tacotok\",\"schedule_type\":\"now\",\"media_type\":\"VIDEO\"}"
  }'

Returns a user_job_id. Poll GET /v1/user_jobs/:id until completed; result.post_id is the TikTok post ID.

Credits & billing

Renders charge credits — same pre-charge / reconcile pattern as every other generation. Publishing is free. See Credits & Billing for cost breakdowns and the pricing formula.

Tip

Renders are the single most expensive generation type in a typical workflow. Before kicking off a batch of 50+ renders, check org credit balance via GET /v1/organizations/:id. Partial batches are painful to clean up.

Sub-topics

Render the Final Video Trigger, poll, handle render failures.

You’ve completed the journey

You configured an agent, generated data-driven ideas, converted one into a vidsheet, edited and generated every cell, rendered the composite, and publish-ready.
