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

By Cecilia Hwung | Last Update:

Summary: The replay files of Leagues of Legends (LoL) are stored as Rofl, with an extension .rofl under the replays folder. For the convenience of sharing and preserving old gameplays from different patch versions, the best way is to convert rofl to mp4. In this post, you will learn how to use VideoProc Converter AI for the rofl to mp4 conversion.

Many players love to replay Leagues of Legends (LoL) to enjoy a highlight moment and learn from others. Although you can directly replay the game within the client, sometimes you might prefer to replay LoL outside the client, share the gameplay video to friends, Discord or video-sharing platforms.

Benefits of Converting Rofl to MP4
  • Converting to mp4 can preserve LoL gameplay forever. Old rofl files will be expired and throw you a replay error since they are created from old patches. You can only replay rofl files created on the current patch.
  • The old replays folder can be a large storage hog (10GB more) with rofl files that are no longer playable.
  • Converting rofl to mp4 allows you to preserve the best resolution, frame rate, system sounds and share to any device and platform.

What Is a Rofl File?

Rofl files are created by Leagues of Legends (LoL) as replay files with an extension .rofl stored under the replays folder. In fact, it is not a video format, and it doesn't contain actual video stream data inside the file. Rofl merely contains instructions for the game engine to properly replay what happened during that session.

The rofl file does not record the games sessions itself, but don't worry, with the following method, you will learn how to replay rofl to record the actual gameplay into mp4 files.
