How to Convert Rofl to MP4 to Replay Outside the League of Legends Client

Many players run into a frustrating issue with League of Legends replays: they don’t always work when you need them. That’s why many start searching for ways to convert ROFL to MP4 so they can revisit their best moments anytime. ROFL files are tied to the game version they were recorded in. So once League of Legends updates, there’s a good chance your old replays just won’t open anymore.

Even when they do work, you can only watch them inside the game client. They can’t be uploaded to platforms like YouTube or Discord, opened in a normal video player, or used in editing software. For this reason, many players convert ROFL to MP4, turning those locked replay files into real videos that can be shared, edited, and watched anywhere.

What Is a Rofl File

A ROFL file is a replay file created by League of Legends. It uses the .rofl extension and is typically stored in the game’s “Replays” folder after a match is played.

Unlike standard video formats such as MP4, a ROFL file does not contain actual video footage. Instead, it stores a set of instructions, match data, and player actions that the game engine uses to recreate the match in real time. This is why ROFL files are usually small in size compared to recorded videos.

However, this also means ROFL files depend entirely on the game client to function. You can’t open them with media players, edit them in video software, or upload them directly to platforms like YouTube. They are also version-dependent, so replays recorded on older patches may no longer work after updates. To make them usable outside the client, you’ll need to convert or record them into a standard video format like MP4.

How to Convert Rofl to MP4 to Watch Anywhere

Since ROFL files don’t contain actual video data, converting them to MP4 requires replaying them in the League of Legends client and recording the gameplay. Using a dedicated game recorder helps you capture all the action at high quality. VideoProc Converter AI is a solid choice for this task. It records gameplay at the original frame rate for smooth motion and supports UHD 4K resolution with hardware-accelerated encoding. You can also enable constant frame rate (CFR) to produce MP4 files that are stable and editing-friendly in software like Premiere Pro, Final Cut Pro, or iMovie.

Thanks to its support for UHD 4K recording, your LoL highlights can be preserved in full UHD 4K quality, including system sounds, smooth motion, and full editing flexibility. The resulting MP4 videos can be shared, uploaded, or edited on any platform, making your old replays fully accessible outside the game client.

Follow these steps to convert rofl to mp4:

Step 1. Find ROFL Files

By default, it is stored in the Documents > League of Legends > Replays folder. You can find it from: C:\Users\[Your Windows User Name]\Documents\League of Legends\Replays.

Step 2. Replay the Rofl in League of Legends

You can create a shortcut for League of Legends on your desktop and then drag and drop a ROFL file onto it to start playing.

Usually, a LoL shortcut is automatically added to the desktop during installation. If you don’t have one, navigate to where you installed the game: open the Riot Games > League of Legends > Game folder. Right-click the League of Legends icon, choose Send to > Desktop (create shortcut), and the shortcut will appear on your desktop.

Note:

Make sure that the LoL game shortcut and the replay files are in the same path. For instance, both on the desktop, or in the same desktop folder. Also, note that you are using the game shortcut, instead of the client shortcut, and the replay is from the same patch.
