Rewind

Ever tried opening a Premiere Pro project in an older version?

Yeah. Premiere isn't a fan of that.

I used to fix this manually using a method Google taught me years ago.

It goes something like this.

Step 1: Make a backup of your project.

Easy.

Step 2: Extract the .prproj file using 7-Zip or WinRAR.

Okay, done.

Step 3: Open the extracted file in a text editor.

Notepad. Sure.

Step 4: Find the project version number and change it.

Wait. Which version? There are multiple version numbers here.

Fine. Changed it.

Step 5: Save everything and compress it back into a .prproj file.

Done.

Step 6: It doesn't work.

Oh, apparently you have to use GZIP compression.

WHY DIDN'T YOU TELL ME THAT BEFORE?

The things we do just to open a project file.

And imagine doing this every time someone sends you a project from a newer version. Especially when you're already running late.

No thanks.

There are already websites that do this.

I tried a few. And here's what I found.

• Free conversions, until they're not.
• File size limits. Bigger file? Pay up.
• No proper privacy policy on some sites.
• And most importantly, you have to upload your project file to their servers.

I'm sure some of them are perfectly fine.

But uploading my working project to some random server just to change a version number?

At least not for me. Sorry.

Started researching things I probably never needed to know as a motion designer.

First, I came across WebAssembly (WASM).

Apparently, you can use it to process files directly in the browser without sending them to a server.

Cool. That's what I need.

But then I found fflate, a JavaScript library that handles compression and decompression right in the browser.

Wait. So I don't even need WASM for this?

Nice.

A little JavaScript, a lot of Googling, and Claude doing most of the coding. (Thanks, Claude.)

And that's how Rewind was born.

Rewind. A little tool for a very annoying problem.

A tiny tool that lets you convert Premiere Pro projects for older versions.

No uploads. No accounts. No paywalls.

Your files stay on your computer. Everything happens inside your browser.

Rewind doesn't magically make newer Premiere features work in older versions.

It changes the project version information to give older versions a chance to open the file. Compatibility isn't guaranteed.

But if it saves you from rebuilding an entire edit?

I'll take that.

Anyway, that's Rewind.

Made it because I needed it. Thought someone else might too.
