YouTube-8M is a large-scale labeled video dataset that consists of 8 million YouTube video IDs and
associated labels from a diverse vocabulary of 4800 visual entities. It also comes with precomputed
state-of-the-art vision features from billions of frames, which fit on a single hard disk. This
makes it possible to train video models from hundreds of thousands of video hours in less than a day
on 1 GPU!
Our goal is to accelerate research on large-scale video understanding, representation
learning, noisy data modeling, transfer learning, and domain adaptation approaches for video.
More details about the dataset and initial experiments can be found in our

Avg. Labels / Video
The (multiple) labels per video are Knowledge Graph
entities, organized into 24 top-level verticals.
Each entity represents a semantic topic that is visually recognizable in video, and the video labels reflect the main topics of each video.
You can download a CSV file
of our vocabulary.
The line number of the label corresponds to its index in the dataset files
with the first label corresponding to index 0. The CSV file contains the following columns:
NumTrainVideos, KnowledgeGraphID, LabelName, FirstVertical, SecondVertical, ThirdVertical
The entity frequencies are plotted below in log-log scale, which shows a Zipf-like distribution:
In addition, we show histograms with the number of entities and number of training videos in each top-level vertical:
