About

ActivityNet Captions contains 20K long-form videos (180s as average length) from YouTube and 100K captions. Most of the videos contain over 3 annotated events. We follow the existing works to concatenate multiple short temporal descriptions into long sentences and evaluate ‘paragraph-to-video’ retrieval on this benchmark.

We adopt the official split:

• Train: 10,009 videos, 10,009 captions (concatenate from 37,421 short captions)
• Test (Val1): 4,917 videos, 4,917 captions (concatenate from 17,505 short captions)
• Val2: 4,885 videos, 4,885 captions (concatenate from 17,031 short captions)
