A clean run timer you can add after recording
This page loads a speedrun-style timer that counts up with two millisecond digits (0:00.00) in Roboto Mono, a monospace font, on a transparent background. Speedrunners, gaming YouTubers and anyone editing “fastest time” attempts use it to add a clean timer to a run after recording: when no live splits were captured, when the in-game timer is hard to read, or when the run is cut into a highlight video.
Monospace digits and fixed-width drawing keep every character in the same place, so the hundredths don’t shimmer or push the seconds sideways. Real transparency matters for gameplay too. Game footage is full of greens and bright effects that a chroma key would cut holes into, and the soft shadow under the digits would turn into a green fringe. A transparent WebM or PNG sequence sits on top of the game exactly as it looks in the preview.
Milliseconds change on every frame, so each frame is encoded. A five-minute run takes about a minute or two to export on a typical computer.

The page checks your browser and marks any download that won't work. Videos are made much faster than real time: a 10-minute timer usually takes a few seconds, and it keeps going if you switch to another tab on a computer. On iPhone, keep the page open until it finishes.
Questions about the speedrun timer
Can it show three millisecond digits?
Yes. Set Milliseconds to 3 digits. The video runs at 30 fps, or 60 if you choose it, so the last digit moves once per frame, like most timers on video.
How do I match the timer to my run?
Set the length to your final time, including milliseconds, and export. Line 0:00.00 up with the start of the run; “Hold at end” keeps the final time on screen.
Can the final time turn gold for a personal best?
Yes. Tick Finish colour and pick gold, and the time changes colour when the timer stops. Tick flash to make it blink.
