Workflow overview
Why this workflow matters
Potentially useful as a reusable automation building block.
Generate Animated Human Videos from Images & Audio with Bytedance Omni Human Built with AlekSystem + Replicate This workflow takes an image + audio, sends them to Bytedance’s omni-human model, waits for processing, and returns a generated video. ⚡ Section 1: Start & Authenticate ▶️ On clicking ‘execute’** → Manual trigger to start the workflow. 🔑 Set API Key** → Stores your Replicate API key so future requests are authorized. Benefit: Secures your API credentials in one place for easy re-use. 🛠️ Section 2: Send Video Generation Request 📡 Create Prediction** → Makes a POST request to Replicate with: image: input image URL audio: input audio URL Model version: 7ec44f5140c7338b3496cbf99ee8ea391a4bc18ff5d1677a146dfc936a91f65b Benefit: Combines visual and audio inputs to start AI-powered video generation. 🔍 Section 3: Track the Prediction 📦 Extract Prediction ID** → Saves predictionId, status, and predictionUrl for polling. ⏳ Wait** → Pauses 2 seconds between status checks (to avoid spamming the API). 🔁 Check Prediction Status** → Queries Replicate using the stored prediction URL. ✅ Check If Complete** → Branches: If status = succeeded → move forward. Else → loop back to Wait until completion. Benefit: Ensures workflow patiently waits for the video instead of timing out. 📽️ Section 4: Process & Return Results 📦 Process Result** → Cleans the API response, returning: status video_url (generated video) metrics created_at & completed_at model: bytedance/omni-human Benefit: Gives you a neat, structured output with the generated video link ready to use. 📊 Workflow Overview | Section | Purpose | Key Nodes | Benefit | | ------------------- | --------------------------- | --------------------------------------------- | -------------------------------- | | ⚡ Start & Auth | Initialize & secure API key | Manual Trigger, Set API Key | Keeps credentials safe | | 🛠️ Send Request | Start video generation | Create Prediction | Submits image+audio to Replicate | | 🔍 Track Prediction | Poll status until done | Extract Prediction ID, Wait, Check Status, If | Reliable async handling | | 📽️ Process Result | Format output | Process Result | Easy access to final video link | ✅ Final Benefits 🎬 Turns static image + audio into full AI-generated video. 🔑 API key stored securely in workflow. 🔄 Handles async generation with auto-polling. 📤 Outputs clean JSON with direct video link. 🧩 Modular — you can connect results to Slack, Gmail, or Google Drive for auto-sharing.
