Benefit: Combines visual and audio inputs to start AI-powered video generation.
🔍 Section 3: Track the Prediction
-
📦 Extract Prediction ID → Saves
predictionId,status, andpredictionUrlfor 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:
