# Generate cinematic videos with OpenAI Sora and uploadtourl hosting
|
||||
|
||||
# 1. Workflow Overview
|
||||
|
||||
This workflow automates the creation of high-quality cinematic videos using the OpenAI Sora API and handles the subsequent hosting of the generated files. It serves as a middle-layer service that transforms simple text or image inputs into professional video assets for two specific use cases: E-commerce product reveals and Social Media "Remixes."
|
||||
|
||||
The workflow operates asynchronously to accommodate Sora's rendering time. It manages the full lifecycle of a video job: receiving the request, crafting optimized prompts, submitting the job, polling for completion, downloading the binary file, and uploading it to a CDN/Storage service.
|
||||
|
||||
**Logical Blocks:**
|
||||
* **1.1 Entry & Routing:** Receives incoming Webhook data and directs the flow based on the `jobType`.
|
||||
* **1.2 Cinematic E-commerce Pipeline:** Logic specialized for 4K product showcases and 360° rotations.
|
||||
* **1.3 Dynamic Social Media Remix Pipeline:** Logic specialized for vertical (9:16) or square (1:1) content with specific stylistic transformations.
|
||||
* **1.4 Async Polling Loop:** A recurring logic gate that checks Sora's API until the video generation is successful.
|
||||
* **1.5 Storage & Delivery:** Downloads the generated MP4 and pushes it to a remote URL via a PUT request.
|

# 2. Block-by-Step Analysis
|
||||
|
||||
### 2.1 Entry & Routing
|
||||
This block acts as the API gateway for the workflow.
|
||||
|
||||
* **Webhook – Receive Video Job**
|
||||
* **Type:** Webhook
|
||||
* **Role:** Entry point for POST requests at `/sora-video-job`.
|
||||
* **Input/Output:** Receives JSON body (product info, styles); outputs data to the Switch.
|
||||
* **Route by Job Type**
|
||||
* **Type:** Switch
|
||||
* **Configuration:** Evaluates `{{ $json.body.jobType.toLowerCase() }}`.
|
||||
* **Outputs:** Routes to "E-commerce" branch, "Remix" branch, or an Error branch if the type is unknown.
|
||||
* **Respond – Error**
|
||||
* **Type:** Respond to Webhook
|
||||
* **Role:** Returns a 400-level error response if the job type is invalid.
|
||||
|
||||
### 2.2 Cinematic E-commerce Pipeline
|
||||
Handles high-end product video generation.
|
||||
|
||||
* **Build E-commerce Prompt**
|
||||
* **Type:** Code
|
||||
* **Role:** Uses JavaScript to construct a detailed Sora prompt emphasizing studio lighting and 360° rotation.
|
||||
* **Variables:** `productName`, `duration`, `style`.
|
||||
* **Sora – Submit E-commerce Job**
|
||||
* **Type:** HTTP Request
|
||||
* **Role:** `POST` to `https://api.openai.com/v1/video/generations`.
|
||||
* **Auth:** Generic Header Auth (`Authorization: Bearer YOUR_KEY`).
|
||||
* **Store E-commerce Job ID**
|
||||
* **Type:** Code
|
||||
* **Role:** Normalizes the `generation_id` from the API response to ensure it can be used in the polling loop.
|
||||
|
||||
### 2.3 Dynamic Social Media Remix Pipeline
|
||||
Handles vertical short-form content generation.
|
||||
|
||||
* **Build Remix Prompt**
|
||||
* **Type:** Code
|
||||
* **Role:** Logic to determine aspect ratios (9:16 for Reels/TikTok, 1:1 for Feed) and applies stylistic "remix" effects.
|
||||
* **Sora – Submit Remix Job**
|
||||
* **Type:** HTTP Request
|
||||
* **Role:** Similar to the E-commerce submit node, but sends remix-specific parameters.
|
||||
* **Store Remix Job ID**
|
||||
* **Type:** Code
|
||||
* **Role:** Extracts the ID for the Remix loop.
|
||||
|
||||
### 2.4 Async Polling & Binary Handling
|
||||
Since Sora is asynchronous, this block loops until the file is ready.
|
||||
|
||||
* **Wait 20s (E-commerce/Remix)**
|
||||
* **Type:** Wait
|
||||
* **Role:** Pauses the workflow for 20 seconds to prevent API rate-limiting and allow rendering time.
|
||||
* **Sora – Poll Status (E-commerce/Remix)**
|
||||
* **Type:** HTTP Request
|
||||
* **Role:** `GET` request to `.../v1/video/generations/{generationId}`.
|
||||
* **Check Done (IF Nodes)**
|
||||
* **Type:** IF
|
||||
* **Condition:** Checks if `status` equals `succeeded`. If false, it loops back to the Wait node.
|
||||
* **Fetch Video (E-commerce/Remix)**
|
||||
* **Type:** HTTP Request
|
||||
* **Role:** Downloads the actual MP4 binary from the `video_url` provided in the successful Sora response.
|
||||
|
||||
### 2.5 Storage & Delivery
|
||||
* **Upload to URL (1 & 2)**
|
||||
* **Type:** `n8n-nodes-uploadtourl.uploadToUrl`
|
||||
* **Role:** Takes the binary MP4 and performs a `PUT` or `POST` to a pre-defined CDN or storage URL.
|
||||
* **Build Response (E-commerce/Remix)**
|
||||
* **Type:** Code
|
||||
* **Role:** Constructs the final JSON payload containing the `publicUrl` and metadata.
|
||||
* **Respond to Webhook**
|
||||
* **Type:** Respond to Webhook
|
||||
* **Role:** Sends the final successful JSON back to the original caller.

# 4. Reproducing the Workflow from Scratch
|
||||
|
||||
1. **Entry Point:** Create a **Webhook** node set to `POST` with the path `sora-video-job`. Set Response Mode to "When Last Node Finishes" (or via Respond to Webhook nodes).
|
||||
2. **Routing:** Add a **Switch** node. Create two rules using String comparison:
|
||||
* If `jobType` equals `ecommerce` -> Output 0.
|
||||
* If `jobType` equals `remix` -> Output 1.
|
||||
3. **Prompt Engineering (Branch 1):** Add a **Code** node. Use JS to take the webhook body and return a template string formatted for high-end product videos.
|
||||
4. **Sora Integration:** Add an **HTTP Request** node.
|
||||
* Method: `POST`.
|
||||
* URL: `https://api.openai.com/v1/video/generations`.
|
||||
* Authentication: Header Auth (`Authorization: Bearer [KEY]`).
|
||||
* Body: Pass the prompt from the Code node.
|
||||
5. **The Polling Loop:**
|
||||
* Add a **Wait** node set to 20 seconds.
|
||||
* Add an **HTTP Request** node (`GET`) calling the Sora status endpoint using the `id` from the previous step.
|
||||
* Add an **IF** node to check if `status` is `succeeded`.
|
||||
* Connect the **False** output of the IF node back to the **Wait** node.
|
||||
6. **Binary Handling:** Connect the **True** output of the IF node to a new **HTTP Request** node. Use the `video_url` from the IF node's data. Set the response type to "File" (Binary).
|
||||
7. **Cloud Storage:** Add the **Upload to URL** node. Configure your credentials for your CDN/storage provider. This node will automatically pick up the binary file from the previous node.
|
||||
8. **Final Response:** Add a **Code** node to format the final JSON output (including the new public URL) and connect it to a **Respond to Webhook** node.
|
||||
9. **Branch 2:** Repeat steps 3–8 for the "Remix" branch, adjusting the prompt logic and aspect ratios in the Code node.
