Why convert ROFL to MKV?
A ROFL file (League of Legends Replay) is a proprietary binary stream of player inputs, unit positions, and game events. MKV (Matroska, introduced 2002) is an EBML-based multimedia container holding video frames, audio tracks, and subtitles. Because ROFL contains no rendered frames, there is nothing to repackage into .mkv.
How to convert ROFL to MKV
OBS Studio FREE
Play the .rofl file in the League of Legends client and record the game window with OBS Studio set to MKV output under Settings > Output.

- ROFL replays are tied to the patch they were recorded on; after a League update, old files stop opening and cannot be recorded.
- OBS Studio outputs MKV natively, making it the most direct path to an MKV recording of a replay.
- Any tool or site claiming a direct ROFL-to-MKV conversion does not work - no video data exists inside the file.
