If your League of Legends match is still in Match History, try Riot’s replay system and record moments with its built-in Highlights tool. If the replay has expired—or the match is already gone—there is no documented way to recreate it as video afterward. To save matches you play from now on, set up OBS before the game and capture the client and gameplay.

First, check whether the match replay is still available

Open Match History in the League client and check the match. Riot says replays can be downloaded from Match History or the end-of-game screen, but they are temporary: “Replays last for the length of a patch cycle, meaning they’ll expire once you patch up.” Riot Support’s Replays FAQ & Pro-Tips explains replay availability and playback.

A replay is not the same as a permanent video file. If the replay is unavailable after a client patch update, the sources do not document a way to recover footage of that past match. Logs are not a substitute: Riot describes match and network logs as diagnostic files, not gameplay recordings. See Riot’s troubleshooting guidance.

Save a clip from an available replay with Riot Highlights

If you can open the replay, watch it in the client and use its recording control to start and stop a clip around the moment you want. Riot calls the resulting clips Highlights; they are saved as WEBM video. The path Riot gives is C:UsersDocumentsLeagueofLegendsHighlights, a Windows-style path.

Record future matches with OBS

OBS captures the running client and game rather than depending on a replay remaining available. Riot’s replay system and OBS therefore serve different purposes: use the client for an available past match, and configure OBS ahead of time for matches you have not played yet.

Advanced option: Riot’s local Replay API

Riot’s Developer Portal documents a local Replay API for playback state, camera and render properties, sequences, and recording control. It is disabled by default and requires configuration in game.cfg. This is an advanced developer-oriented route, not a necessary setup for ordinary clip recording. See Riot’s Replay API documentation.
