Video Understanding & Analysis via Google's Gemini
Ask questions about video content, generate summaries, or extract structured information from clips inside a CNAPS Studio flow. Four Gemini tiers let you trade off speed, cost, and reasoning depth. Runs on Google's servers via API.
🔑 Requires a Google API key
What it does
This node connects your CNAPS Studio flows to Google's Gemini models for video analysis through the Gemini API. Feed it a video and a natural-language instruction — summarize, answer questions, transcribe, extract structured data — and the node returns a text response. Unlike the generation nodes, this node analyzes existing video rather than creating new content, and its outputs are text.
Problem it solves
- Video understanding inside a pipeline — Analyze clips as a flow step: e.g., generate a video with Sora/Veo, then run Gemini analysis for automated QA or captioning, all in one flow.
- Speed/cost/depth tiers — Match the model tier to the task: fast defaults for routine analysis, Pro for complex multi-step reasoning, Flash-Lite for high-volume batch transcription.
- Reproducibility across runs — The prior-gen
gemini-3-flashremains available when consistency with earlier analysis runs matters more than latest-gen quality
Configuring the Node
Basic Settings
Model name
Model | Best For |
gemini-3.5-flash | Default fast tier — latest-gen Flash, best speed/quality trade-off for most analyses |
gemini-3.1-pro | Highest-quality reasoning — complex multi-step analysis, nuanced summaries, long-context understanding |
gemini-3-flash | Prior-gen fast tier — cost-efficient legacy option, useful when reproducibility with earlier runs matters |
gemini-3.1-flash-lite | Ultra-lightweight — cheapest per call, great for high-volume batch processing or simple transcription |
System prompt or instruction for video analysis
- Your main instruction for what to analyze or extract — e.g., summarization, question answering, transcription, or structured output.
