How to film a slow-motion dance clip with perfect sync

How it works

If the video plays at half speed, the music you danced to needs to have been twice as fast.

Steps

1. Make a sped-up version of the section (many editors and DJ apps can).
2. Record in Slo-mo while dancing to the fast version.
3. In editing, put the normal-speed song under the slowed clip.
4. Line up the first beat.

Light

Slow motion needs plenty of light.
