About OpenOlder

OpenOlder is a small independent project made by Jiayi, an independent developer based in Canada. It exists because editors and producers often receive project files saved in a newer version of their software than the one they have, and updating isn't always possible: a studio may be locked to one version, or a client's machine may not support the new release.

How it works

A Premiere Pro project (.prproj) is compressed XML. OpenOlder opens it in your browser, adds back the fields older versions expect, sets the version number and gives you a new copy. Ableton Live sets (.als) are handled the same way. Everything runs on your own computer: your files are never uploaded, there is no account, and the original file is not changed.

What it can and can't do

• Premiere Pro: converts projects and Productions from 2026 back to older versions. Features that only exist in the newer release may show as missing.
• Ableton Live: converts Live 12 sets for Live 11 (beta). Devices that only exist in Live 12 can't be recreated.
• It doesn't convert media, render files or plug-ins, only the project file.

Always keep the original and check the converted project before relying on it.

Credits and independence

The Premiere conversion is based on prem-down by Luis Gómez Gutiérrez (MIT) and the Ableton conversion on live_set by Michael Slinn (noncommercial license). Details are on the licenses page. OpenOlder is not affiliated with or endorsed by Adobe or Ableton.
