Replay

A Replay is a feature in modern original Street Fighter games and remakes of older Street Fighter games that didn't originally support the feature.

Description
Most modern SF games save online battles in the form of a log. The amount of games saved varies from game to game. Most games that do this allow the player to store replay data in their hard drive to be kept even after long times. Some titles even allow players to save replays of offline matches.

Individual games even have their own feature within replays, such as Street Fighter X Tekken's Replay Analyzer that shows the highest amounts of actions in a match, or Street Fighter V that allows frame by frame analysis of replays, potentially allowing for better Frame Data analysis than simply attacks.

It should be noted that replay files are not video files, they are simply a saved sequence of inputs and data in a very small form that the game is programmed to read to be able to play back, if it was a true video form they would take significantly more hard drive space even with modern compression methods. Some games have Upload to Youtube features that require the replay to be played in full so the platfrom records the action before sending the encoded video to said website in a format more acceptable.
