This would be one of the title sequences in the series of Steven Universe crossover episodes of the Disney/BBC version of Doctor Who.
Seen in "Lars and the Hostile Daleks" starring the Eighth Doctor, Paul McGann.
I'd credit the creator of the visuals, but the video and its creator are no longer on YouTube.
I added the Disney and BBC logos, the names of Paul McGann and Selena Gomez (and the characters they play in the episode), the episode title and names of the writers (once again in the style of the 2005-2010 title sequences).
