Simple Slate

A simple JavaScirpt based slat “app” for your phone or tablet.

How to Use

The slate provides only a limited set of functionality, basically only what I’ve found I’ve needed so far.

To enter a production title, tap the production box and enter it with the onscreen keyboard.

To change the scene or take, swipe up to increment or down to decrements the value. Changing the scene value resets the take counter to 1.

To change the FPS, swipe right or left to step through the available options. Current frame rates are 23.98, 24, 25, 29.97, 50, and 59.94. Changing the FPS setting changes the frame counter range on the time display.

Note because this is a JavaScript app, the may be imperfect, however it should run at 60 FPS and therefore should display relatively accurately. Additionally iOS devices throttle requestAnimationFrame calls when the device is in low power mode to 30 FPS.

Note, drop frame time codes are not handled, even though 30 FPS and 60 FPS are given as NTSC drop code frame rates. I don’t think this should be a problem though, given the basic nature of this app.

Additionally the app saves state between uses, and can be reset/cleared and updated by holding the hold to reset box for half a second.

Support and Updates

I built this for me, and as quickly and simply as possible. If there’s interest in features, I may consider adding them, but this is not to be considered a point for point alternative to a real slate app.

Additionally, I only have an iOS devices to test this on, so I cannot guarantee functionality.

I’m open to considering new potential features, if there is interest, but I cannot make any guarantees that they will either be added or if they are added in a timely manner.
