Simply select any video file from your device. Our tool supports common video formats and automatically loads your content for analysis.
Our sophisticated system combines multiple analysis techniques to evaluate every frame. Computer vision algorithms assess brightness, contrast, color balance, and visual complexity, while AI object detection identifies interesting subjects and elements within each frame. The scene recognition component analyzes composition and visual appeal, working alongside quality assessment tools that measure sharpness, lighting conditions, and overall image clarity.
The tool extracts frames throughout your video and scores each one using comprehensive criteria. Visual clarity and sharpness are evaluated alongside optimal lighting conditions and engaging composition. The system also considers color vibrancy and contrast levels, object detection confidence scores, and overall scene complexity to determine which frames will be most appealing to viewers.
