Speedrun Retime Extension от Yoshie2000

On pages that contain videos, you can open a toolbar that contains tools to time parts of the video to the frame. You can change the video speed, move through frames and set frames for the start / end of the speedrun itself, as well as loading sections. The IGT (in-game-time) / RTA (real-time-attack) times will be calculated based on the selected frames automatically.
