I enjoy playing games and often use replay files generated by the game engine to review my performance. These files allow me to rewatch matches from different perspectives, helping me analyze mistakes and improve my strategies. Many competitive and strategy games support replay files, such as League of Legends, Fortnite, and Rocket League.
However, I soon realized a limitation that replay files can only be opened within the original game. This makes them inconvenient to use, especially when I want to share my highlights or achievements with friends. Since replay files are not actual video files but data records, they cannot be played on common media players or easily shared across different platforms.
Because of this, I started looking for a way to convert replay files into a more accessible format like MP4. After trying different methods, I found that replay files cannot be directly converted to MP4 because they are not video files but data records of in-game actions. Therefore, I decided to convert a replay to MP4 by recording the gameplay.
