ezRetime

A speedrun video retimer for Twitch, YouTube, and more! Click the extension icon on a page to run it.

Use the comma ( , ) and period ( . ) keys on your keyboard to go forward or backward one frame in the run. Press ctrl+comma to set the start time of the run. Likewise, ctrl+period sets the end of the run. Once these are both set, the time difference will be shown in the menu and you can copy the mod message to your clipboard. You can also press the S key to toggle Turbo Mode, which increases the video speed to 5x. With the latest update, it is now possible to add multiple splits and an extra offset for more flexible retiming.
