QUICK ANSWER
Is it possible to convert ROFL to MP4?
No - not a direct conversion.

Play the replay in the League of Legends client and record the screen with OBS Studio, NVIDIA ShadowPlay, or Windows Game Bar to get an MP4. Any site or tool claiming a direct ROFL-to-MP4 conversion does not work as advertised.

Why convert ROFL to MP4?

A ROFL file (League of Legends Replay) begins with a 'RIOT' signature, followed by a JSON match-statistics block and a proprietary game-event stream - no frames are stored. MP4 (ISO Base Media File Format container, standardized 2003) holds compressed video and audio. Because ROFL contains no pixel data, there is nothing to transcode into .mp4.

How to convert ROFL to MP4

OBS Studio FREE

Play the .rofl file in the League of Legends client and record the game window with OBS Studio; OBS outputs MP4 directly.

NVIDIA ShadowPlay FREE

On systems with an NVIDIA GPU, use ShadowPlay (GeForce Experience) to record the replay window; output is MP4.

Windows Game Bar FREE

Press Win+G while the replay plays in the League client and click Record; clips are saved as MP4 to Videos > Captures.

Quality & what to watch

  • ROFL replays are version-locked to the patch they were recorded on; after a League update, old files stop working and cannot be recorded.
  • A 30-minute ROFL file is a few megabytes; the same match as a 1080p MP4 would be several gigabytes.
  • Sites claiming direct ROFL-to-MP4 conversion do not work and some bundle adware targeting players searching for replay tools.

Frequently asked questions

Is there any ROFL-to-MP4 converter?
No - the ROFL format holds game event data, not video; any tool advertised as a direct converter does not work as claimed.
Why is my ROFL replay not opening?
Replays are version-locked to the patch they were recorded on; after a League update, old ROFL files stop working because the game data they reference has changed.
Can I use Windows Game Bar instead of OBS?
Yes - press Win+G while the replay plays and click Record; the output goes to Videos > Captures, though quality and codec options are more limited than OBS.
