Generate videos from images with Wan 2.2 I2V A14B AI model

Generate Videos from Images with Wan 2.2 I2V A14B AI Model 🌍 Overview This workflow connects n8n with Replicate’s Wan-Video model to generate video content from an image + prompt. It handles: 🔑 API authentication 📤 Sending a generation request ⏳ Polling until completion 📥 Returning a downloadable video link --- 🟢 Section 1: Start & Authentication 🔗 Nodes: 1️⃣ On clicking 'execute' (Manual Trigger) ▶️ Starts the workflow manually when you click Execute Workflow. 2️⃣ Set API Key 🔑 Stores your Replicate API Key securely inside n8n. Value: YOURREPLICATEAPIKEY 💡 Beginner Benefit: ✅ No need to hardcode API keys in every request ✅ Easy to swap keys for different accounts --- 🔵 Section 2: Send Video Generation Request 🔗 Nodes: 3️⃣ Create Prediction (HTTP Request) 📤 Sends a request to Replicate API → /v1/predictions Model: wan-video/wan-2.2-i2v-a14b Input Parameters: 📝 prompt → your text description 🖼️ image → input video/image URL 🎲 seed → reproducibility 🎞️ numframes → 81 frames ⏩ sampleshift → 5 ⚙️ samplesteps → 30 🎬 framespersecond → 16 4️⃣ Extract Prediction ID (Code) 🆔 Pulls out the prediction ID + status from Replicate’s response. This ID is needed for polling until the video finishes generating. 💡 Beginner Benefit: ✅ Automates the API call to generate video ✅ Extracts ID → avoids manual copy-paste --- 🟣 Section 3: Polling & Status Check 🔗 Nodes: 5️⃣ Wait (2 sec) ⏳ Adds a short delay before checking progress. Prevents API spam 6️⃣ Check Prediction Status (HTTP Request) 🔄 Calls Replicate API → /v1/predictions/{id} Checks whether the video is still processing or finished 7️⃣ Check If Complete (IF Node) ❓ Compares status → succeeded or not ✅ If complete → goes to Process Result ❌ If not → loops back to Wait and tries again 💡 Beginner Benefit: ✅ Automatic re-checking → you don’t need to refresh manually ✅ Works until result is ready --- 🟡 Section 4: Process Final Result 🔗 Nodes: 8️⃣ Process Result (Code) 📥 Once complete, extracts: ✅ Status 🎞️ Output video URL 📊 Generation metrics ⏱️ Timestamps (created\at, completed\at) 🧩 Model used Final output = direct video URL you can download/share 🎥 --- 📊 Final Overview | Section | What Happens | Why It’s Useful | | --------- | ------------------------------ | --------------------------------- | | 🟢 Auth | Manual Trigger + API Key | Secure, easy start | | 🔵 Send | Create Prediction + Extract ID | Kicks off video generation | | 🟣 Poll | Wait + Check Status + IF | Auto-checks progress until done | | 🟡 Result | Process Result | Gives final video link + metadata | --- 🚀 Why This Workflow Rocks 🎥 Video from Image + Prompt → AI-powered video generation in minutes 🔄 Fully automated → from request to final video, no manual checks 🔑 Secure → API keys handled safely ⚙️ Customizable → tweak frames, FPS, prompt, seed --- ✨ With this workflow, you’ve got a personal AI video generator inside n8n — all you need to do is provide a prompt + input image/video, and you’ll get a fresh AI video link back. ---
