How to make a mashup of two YouTube videos
Quick answer: To make a mashup of two YouTube videos, paste two YouTube links, set a cue on each deck, get the tempos, match the speed, sync start and mix and share it.
- Paste two YouTube links. Each one loads in its own deck with YouTube's normal player. Watch, youtu.be, Shorts and YouTube Music links all work.
- Set a cue on each deck. Play to the bit you want (the drop, the chorus) and press Cue in here. Add Cue out here if you want that part to loop.
- Get the tempos. Type the BPM if you know it, or press Tap tempo along with the beat about eight times.
- Match the speed. On deck B, press Match to deck A. It picks the closest speed YouTube offers for that video.
- Sync start and mix. Press Sync start: both decks jump to their cue and play together. Slide the crossfader, or press Fade to B for a smooth handover.
- Share it. Copy share link saves every deck, cue, speed and the fader position in the link. Whoever opens it hears the same mix, played from YouTube.
How is this different from Rave.dj-style mashups?
Sites like Rave.dj download the songs, remix the audio on their servers and play you their own file. That file isn't a YouTube view, so the artist gets nothing, and downloading YouTube audio breaks YouTube's terms. Here, the original videos play in YouTube's own embedded players and this page only moves the controls YouTube gives every site: volume, speed and position. The upside: views and ad money go to the creators. The downside: no stem separation, and the speed steps are the ones YouTube offers.
Tips for a mashup that actually sounds good
Pick songs within about 5–8% of each other's tempo, or one at roughly double the other (70 and 140 BPM line up fine). Start the beat-heavy song on deck A, since it leads the sync, and bring the vocal in on deck B. Loop a 4- or 8-bar section with cue in/out so the instrumental keeps going under the vocal. If the beats slowly drift, the tempos aren't close enough at the speeds YouTube allows for that video; try another upload of the song or another pair.
Frequently asked questions
Do creators still get views and ad revenue?
Yes. Every song plays in YouTube's official embedded player, exactly like a video embedded on a blog. YouTube counts the view and shows its ads as usual. This page never downloads or re-streams the audio.
Can I download my mashup?
No, and that's on purpose. The music stays on YouTube, so there's nothing to download. You can save the mix as a share link and play it again any time.
Why does a video say it can't be played here?
Some owners turn off playing their videos on other sites, and some videos are blocked in some countries. Search YouTube for another upload of the same song, such as the lyric video or the artist's "Topic" channel, and paste that link instead.
Does it work on my phone?
Partly. Most phones, iPhones especially, only let one video play at a time, so you'll hear one deck. A laptop or desktop browser works best.
How does tempo matching work without the audio?
You give each deck its BPM (typed in or tapped), and the tool sets deck B's YouTube playback speed so its beat matches deck A. Many videos allow fine speed steps; on videos that only offer 0.25× steps the match is rough and the tool tells you.
Is anything uploaded or stored?
Nothing is uploaded. Your mix lives in the page address (the share link) and, if you like, in a recent list in your own browser. YouTube's player works under YouTube's own privacy policy, using its privacy-enhanced mode.
Can I post the mashup on social media?
Not as a recording: capturing and reposting the songs needs the rights holders' permission. Sharing the link is fine, because it just plays the original videos from YouTube.
