I get asked a lot about the correct way to slate.
If it’s not a professional production and you’re just wanting to make sure the sound syncs then you can keep it simple with a clap.
You can move up a notch with things like slate apps for your iPhone (they’re fun to play with at home but drain your battery like crazy).
But, ultimately, I believe it’s always a good initiative to learn like the pros and make that your practice. Then you’ll look like you know your stuff when you get on that first big set.
And luckily for you there is a video (by RocketJump Film School) that can show you!
TIP: Stay watching to the end because the what-not-to-do section is pretty entertaining…
