# Color Boost Video

## Overview

Extracts frames from a video, amplifies color intensity, and reassembles them into a modified video.

1. **Video Input** - A video is loaded.
2. **Frame Iteration** (`nodetool.video.ForEachFrame`) - Frames are extracted.
3. **Color Enhancement** - Each frame's exposure and saturation are amplified using `lib.image.color_grading.Exposure` and `lib.image.color_grading.SaturationVibrance`.
4. **Reassembly** (`nodetool.video.FrameToVideo`) - Enhanced frames are recompiled into a new video stream.
