What happened to Two YouTube Videos and a Motherfucking Crossfader?
Nobody killed it: the parts it was built from were switched off, one by one. The remake works again, right here, on phones too.
The original (2009)
In the summer of 2009 a page appeared at TWOYOUTUBEVIDEOSANDAMOTHERFUCKINGCROSSFADER.COM (the domain was registered on 26 July 2009). It did exactly what it said: two YouTube videos side by side, a search box under each, and one crossfader in the middle. Type “terminator trance remix” on the left, “beverly hills cop trance remix” on the right, slide, and you were a DJ. A party button in the corner turned the purple starfield into a party.
It travelled through blogs and forums (The Next Web wrote about it in November 2009) and became one of those web toys people kept sending each other. It was made by Jake Elliott (dai5ychain.net).
Why it stopped working
- The players were Flash. The page used YouTube’s old Flash player. YouTube moved to HTML5 video by default in 2015, and Flash itself was switched off for good at the end of 2020.
- The search was Google’s AJAX Search API: a free video search that ran in your browser and needed no key. Google retired it in the early 2010s. Today a website can only search YouTube through the official API, with a daily limit.
The original page is still online at its old address, frozen in time, but its players and search boxes no longer load anything.
The remake (2026)
Two Videos and a Motherfucking Crossfader rebuilds it on today’s YouTube player: the same purple starfield, the glitter letters and the opening trance remixes, working in any modern browser and on your phone. The extras stay out of sight until you want them:
- sound effects: airhorn, siren, laser, shotgun click-clack-boom, crowd, 808 drop, scratch and rewind, plus a 2009 tab with the synthesised originals;
- more knobs: speed, nudge, tap tempo, tempo matching, crossfader curves, auto-fade, and themes (beach, space, christmas, love, frutiger aero);
- more from this channel under each deck, to find the next track;
- REC, which records your moves and turns them into a link that replays your mix for anyone.
Got an old mix link? The remake reads the same #leftvideo/rightvideo format: keep everything from
the # onwards and put twovideosandamotherfuckingcrossfader.com/ in front of it.
Why “Videos” and not “YouTube Videos”?
YouTube’s rules for sites that use its player and search don’t allow “YouTube” in a site’s name or web address. So the remake dropped one word and kept the rest, motherfucking included.
Did you search for one of these?
Two YouTubes and a Motherfucking Crossfader, two YouTube videos and a crossfader, twoyoutubesandamotherfuckingcrossfader, “that 2009 YouTube DJ site”: it’s this one. Go mix.
