# Keyframe Screenshot Analysis

> In BibiGPT Visual summary, Screenshot analysis reads PPT key frames—charts, code, and slides—not only the captions.

## Overview

Open Visual summary on the right of a video page and switch to Screenshot analysis. It reuses PPT key frames and reads each still with the vision model you pick. Use it for charts, code screenshots, and slide decks.

## Pain Point

I want AI to see the picture, not only hear the audio. Charts and code in a tutorial never show up in a text-only summary.

## Key Features

* Reuses extracted PPT key frames—no extra manual screenshots
* Choose among vision models such as Gemini 3.0 Flash, Qwen3.5 Omni Plus / Flash, Seed 2.0 Pro, GLM-4.6V, and GLM-5V Turbo
* Auto-picks key frames (for example 10, limited by the model); tap Start keyframe analysis
* Results offer PPT mode and Re-extract
* Complements Video understanding: details on stills vs. the whole clip

## Highlights

Charts, board work, and code that never made the captions can be read frame by frame.

## Use Cases

* Coding or design tutorials where the step is on screen
* Talks packed with slides and data charts
* Explaining one still instead of summarizing the whole video

## Tips

* Run PPT keyframe extraction first so Screenshot analysis has better stills
* Stay on a normal summary when captions are enough; turn this on when the picture matters
