There are many video hosting sites beside YouTube and, collectively, they hold a massive corpus of content. The Videos data source collects content from many of the lesser-known video hosting sites. You can use this data source in conjunction with the YouTube and DailyMotion sources for maximum coverage.
For more information, take a look at Understanding the Output Data in our documentation suite.
Example Use Case:
You're collecting statistics on the number of times your new product is used in videos. Activate all three video data sources in DataSift (YouTube, DailyMotion, and Video) and run a filter for all videos that mention the product in the title or category elements.
