How to make Tandem yours

  1. Open it in the studio

    “Use this template” opens Tandem in the editor with its sample words and pictures in place. Sign in if you are asked to.

  2. Bring in your brand

    Type your website address and the editor reads your logo and colours from it. Or upload a logo, and the colours are matched to it.

  3. Change what it says

    Rewrite the 20 lines under Content yourself, or ask the assistant for a change in plain words. Put your own screenshot or clip in its place under Media.

  4. Choose a format and render

    Pick 16:9, 9:16, 1:1 or 4:5, choose a length, record the voice-over and press “Render video”. The film comes back as an MP4.

Questions about Tandem

How long is Tandem?

24 seconds as designed. The editor has two longer cuts too: Extended (about 34s) and Full length (about 41s). A longer cut adds beats of its own. Nothing is shown twice. The pace can be slowed too: Steady (about 20% longer) or Relaxed (about 45% longer).

Can I make Tandem vertical?

Yes. It comes in 16:9 landscape, 9:16 portrait, 1:1 square and 4:5 social. Switch between them in the editor before you render.

Can I use my own screenshots and video?

Yes. It has one place for it under Media, “Finished screen: screenshot or video”. It takes PNG, JPG, WebP, SVG, MP4 or WebM files.

Does it have a voice-over and music?

It has a voice-over, read by one of 20 voices, and you can switch it off. The music is a choice of Original score, Quiet lift, Open horizon or Human warmth. Its sound effects can be switched off too.

Can I use my own logo and colours?

Yes. Upload a logo, or type your website address and the editor reads the logo and colours from it. Tandem has 5 colours to set: colour of what went well, colour of what was taken out, primary color, background and text color. The typeface is Inter, DM Sans or Space Grotesk.
