+# The StoryFrames Dataset
+StoryFrames is a human-annotated dataset created to enhance a model's capability of understanding and reasoning over sequences of images.
+It is specifically designed for tasks like generating a description for the next scene in a story based on previous visual and textual information.
+The dataset repurposes the [StoryBench dataset](https://arxiv.org/abs/2308.11606), a video dataset originally designed to predict future frames of a video.
+StoryFrames subsamples frames from those videos and pairs them with annotations for the task of _next-description prediction_.
+Each "story" is a sample of the dataset and can vary in length and complexity.
+
+The dataset contains 8,881 samples, divided into train and validation splits.

+
+## What Is a Story in StoryFrames?
+* **A story is a sequence of scenes:**
+Each story is composed of multiple scenes, where each scene is a part of the overall narrative.
+
+* **Scenes consist of two main components:**
+  * **Images**: Each scene is made up of several frames (images) that have been subsampled from the original video.
+  * **Scene Description**: There is a single textual description for each scene (i.e., one or more images) that captures the plot of the scene.
+
+## How Is the Data Organized?
+* **Temporal Markers:**
+  * `start_times` and `end_times`: These fields provide the time markers indicating when each scene begins and ends in the video. They define the boundaries of each scene.
+
+* **Frame Subsampling:**
+  * `subsampled_frames_per_scene`: For each scene, a list of frame timestamps is provided. Each timestamp is formatted to show the second and millisecond (for example, `frame_sec.millisec` would be `frame_1.448629`). These timestamps indicate which frames were selected from the scene.
+
+* **Image Data:**
+  * `scenes`: In a structure that mirrors the subsampled timestamps, this field contains the actual images that were extracted. The images are organized as a list of lists: each inner list corresponds to one scene and contains the images in the order they were sampled.
+
+* **Narrative Descriptions:**
+  * `sentence_parts`: This field contains a list of strings. Each string provides a description for one scene in the story. Even though a scene is made up of multiple images, the corresponding description captures the plot progression over all images of that scene.
