A video that gets far more views than its channel usually does. We compare each video with the average of the channel's nearby videos in the same format (long form or Shorts) at the same age, so 10x means ten times the views that channel normally reaches by then.

By outlier score by default. You can also rank by views per hour (how fast a video is gaining views), views per subscriber (reach beyond the channel's audience) or total views, and filter by upload window, format, niche and a minimum view count.

Channels with 100,000 or more subscribers that TubeStats tracks. Scores are recalculated every day, and they cap at 100x+ because beyond that the figure says more about the baseline than about the video.

The share of a niche's channels that landed a 5x or better video in the chosen window, so a niche ranks high because its creators break out often, not just because it is large.
