About

Frame Timer Extension is an addon that allows you to quickly and accurately calculate the time between 2 frames in a YouTube video. This tool is made for retiming speedruns.

This extension works the exact same way as the original yt-frame-timer (https://slashinfty.github.io/yt-frame-timer/), but with a few improvements such as:
- Buttons to automatically set the start time, end time and frame rate.
- Always with you and no extra tabs needed.
- Easily jump a specific number of frames forward or backward with a button click.
- YouTube keyboard controls (such as arrow keys) are supported.
- Easily set the playback speed of the video

You can find the source code and documentation for this tool on GitHub: https://github.com/PottuGD/frame-timer-extension
