Scrolling Is Evil · Tools

Film slate

A clapboard in the browser for a shoot where you do not have a slate. Scene, take, and roll are large enough to read on camera. Clap can flash the screen and play a short beep.

How it works

The clap button closes the top stick for 120 milliseconds. With Flash on, the board turns white for those 120 milliseconds. With Beep on, the browser plays a 1,000 Hz sine wave for 70 milliseconds through the Web Audio API, starting from the tap. A camera pointed at the screen can use the flash as a picture mark and the beep as a sound mark. If the device asks for less motion, Flash starts off. Next take adds one when the take is a whole number. Fill the screen hides this text. Scene, take, and roll stay in this browser only.
