G: TL;DR: You can't open .prproj files natively on Fedora. Your options are:

1. Use Adobe Premiere via Windows or macOS

• Safest and most compatible option.
• Try opening the project in the oldest available version of Premiere Pro (ideally CS6 or CC 2013) to avoid compatibility issues.

How:

• Use a real Windows machine or:
  • Install Windows in a VM (e.g. via VirtualBox, QEMU/KVM)
  • Use dual boot if you have the space

2. Try Wine or PlayOnLinux (limited success)

• Premiere doesn't work reliably under Wine.
• CS6 is your best bet if you want to try anyway.
• You'll likely run into crashes, missing codecs, or project corruption.

3. Use third-party tools to extract or convert

No tool fully reads .prproj, but you can try:

• pproj2afdr: Converts Premiere XML to DaVinci Resolve AAF/XML (outdated, limited support).
• Manual extraction: Since .prproj is an XML file, open it with a text editor and manually extract media paths or sequences for rebuilding.

4. Alternative: Rebuild manually in a Linux NLE

If you just want the timeline back:

• Open .prproj in a text editor.
• Look for clip names, paths, and timeline structure.
• Rebuild in Kdenlive, DaVinci Resolve (free), or Olive.

---

Best path forward: Open in Premiere CS6/CC 2013 on Windows (even in a VM), export to XML or AAF, and import into Resolve or Kdenlive.

Let me know if you'd like help setting up a VM or finding an old version of Premiere.
