Google Nano Banana 2 Reference to Image

Nano Banana 2 Reference to Image (Gemini 3.1 Flash Image) is Google's advanced AI-powered video-to-image generation model, designed to generate high-quality static images from video clips combined with text instructions. Built on the same cutting-edge model as Nano Banana 2 Edit, it adds the ability to use video content as a rich reference source — extracting visual context, themes, and key frames to synthesize new images with precision and semantic awareness.

This model is ideal for creating thumbnails, posters, promotional artwork, and scene summaries by leveraging the visual richness of existing video content alongside natural language guidance.

Why Choose This?

  • Video as reference — Provide a video clip (HTTP URL or YouTube URL) and let the model extract its visual context to guide image generation.

  • Multi-image reference — Optionally upload up to 10 additional reference images to complement the video input for complex compositions.

  • Natural language control — Describe exactly what you want with a text prompt; the model understands context, themes, and relationships from both the video and text.

  • Thinking levels — Choose how much internal reasoning the model applies — higher thinking levels improve quality on complex tasks.

  • Media resolution control — Balance detail and token usage for input video frames with LOW, MEDIUM, or HIGH media resolution modes.

  • Web & image search grounding — Optionally enable real-time web or image search to enrich generation with current information.

  • Multi-resolution output — Generate at 1K, 2K, or 4K resolution.

  • Flexible aspect ratios — Multiple options including 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, and 21:9.

  • Format choice — Export in PNG or JPEG format.

How It Works

The model analyzes your video clip by sampling frames at the specified FPS rate, then interprets the visual content within its multimodal context window. Combined with your text prompt and any additional reference images, it synthesizes a new image grounded in the video's themes, style, and key visual elements. This makes it especially powerful for creating content that is visually consistent with existing video assets.

Parameters

Core Inputs

ParameterRequiredDescription
promptYesText description of the desired output image
video_clipsYesSource video clip(s) for reference generation (max: 1, see below)
imagesNoAdditional reference images (max: 10, click "+ Add Item" to add more)

Video Clip Fields

FieldRequiredDescription
urlYesURL of the source video clip. Supports HTTP URL or YouTube video URL. HTTP video is limited to 15MB.
startYesStart time in seconds for trimming the video clip (min: 0)
endsYesEnd time in seconds for trimming the video clip. Set 0 to use the whole video.
fpsYesFrame sampling rate (FPS) of the video clip. Range: 0–24. Lower values reduce token usage.

Output Options

ParameterRequiredDescription
aspect_ratioNoAspect ratio: 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9
resolutionNoOutput resolution: 1k (default), 2k, 4k
output_formatNoOutput format: png (default), jpeg

Advanced Options

ParameterRequiredDescription
thinking_levelNoReasoning depth: default, high, minimal. Higher levels improve quality on complex tasks but increase latency.
media_resolutionNoHow input media frames are processed: default, low, medium, high. LOW reduces tokens per frame, allowing longer videos.
enable_web_searchNoIf enabled, grounds generation with real-time web information.
enable_image_searchNoIf enabled, grounds generation with real-time image search results.

How to Use

  1. Provide a video clip — enter the video URL (HTTP or YouTube) and set start/end times and FPS sampling rate.
  2. Write your prompt — describe the output image clearly (e.g., "Create a cinematic poster based on the key scenes in this video").
  3. Add reference images (optional) — upload additional images to guide composition or style.
  4. Choose aspect ratio (optional) — select a preset or leave empty for default.
  5. Select resolution — choose 1K, 2K, or 4K based on your quality needs.
  6. Choose output format — PNG for transparency support, JPEG for smaller file size.
  7. Adjust advanced settings (optional) — set thinking level, media resolution, or enable search grounding.
  8. Run — submit and download your generated image.

Pricing

The total cost is determined by the output image resolution multiplied by the number of output images, plus optional per-request fees for video clip input, web search, and image search grounding.

SKU Prices

The video clip fee (0.07),websearchfee(0.07), web search fee (0.014), and image search fee ($0.014) are each charged once per request when the respective feature is enabled, regardless of content volume.

Best Use Cases

  • Video Thumbnail Generation — Automatically create compelling thumbnails that reflect the video's content and mood.
  • Promotional Posters — Generate movie-style or campaign posters grounded in actual video footage.
  • Scene Summarization Art — Create visual summaries or highlight artwork from long-form video content.
  • Brand Content Creation — Produce consistent image assets from brand video campaigns.
  • Educational Infographics — Transform instructional videos into static visual materials.
  • Social Media Assets — Generate platform-optimized images (vertical, square, landscape) from video content.

Pro Tips

  • Use low FPS (0.5–1) for long videos to keep token usage within limits while still capturing key frames.
  • Set precise start/end times to focus the model on the most relevant segment of your video.
  • Combine specific text prompts with the video input — vague prompts may produce generic results.
  • Add reference images alongside the video to guide composition style more precisely.
  • Use thinking_level: high for complex scene interpretations or when visual fidelity matters most.
  • Set media_resolution: low when analyzing long videos to allow more frames within the context window.
  • 2K offers excellent quality at a reasonable price — only $0.04 more than 1K per image.
  • YouTube URLs are supported directly — no need to download and re-upload public videos.

Notes

  • Both prompt and video_clips are required fields.
  • Maximum video clips: 1 per request.
  • HTTP video URLs are limited to 15MB; use YouTube URLs for larger videos.
  • Maximum additional reference images: 10.
  • FPS range: 0–24. Higher FPS captures more frames but consumes more tokens.
  • The video clip fee ($0.07) is a flat per-request charge, not per frame or per second.
  • If aspect_ratio is not selected, the model uses a default ratio.
  • 4K resolution costs 2× the standard 1K rate.
  • Ensure your content and prompts comply with Google's Safety Guidelines.
