Gemini Video Understanding API Background

Video understanding is an advanced capability in the AI field, requiring models to simultaneously process visual, temporal, semantic, and other multi-dimensional information. Traditional video analysis solutions often require frame-by-frame extraction, manual annotation, or complex preprocessing workflows, resulting in high development costs and low efficiency.

Gemini 2.5 Pro, as Google's latest multimodal large model, natively supports video content analysis. It can:

  • Directly understand video content: No preprocessing needed, directly input video files for analysis
  • Capture temporal sequence information: Understand dynamic changes and event development in videos
  • Extract key scenes: Identify important frames, characters, objects, and actions
  • Generate structured descriptions: Output video summaries, scene classifications, content tags, etc.

This capability is extremely rare in the market, as most AI models only support static image analysis. Mastering Gemini video understanding API will bring significant competitive advantages to your applications.
