How to replace a sky in video without a rotoscope graph

Sky Replace is a dedicated local workbench for dull or blown-out skies. Preview the horizon on a pan before you export.

The short answer

Sky Replace swaps the lid on outdoor plates. It is not a global grade. Preview the horizon on a pan, then export locally. Download for free 1s/3s/5s previews with no account; pricing unlocks export.

When a sky module beats a LUT

  • The sky is clipped white or a flat grey lid
  • Travel, landscape, and aerial clips with a readable horizon
  • You still want to grade later — swap first, then AI Color Enhance

When to skip it

  • Night interiors and studio sets — there is no sky to swap
  • Trees or wires crossing the horizon on a fast pan — preview first
  • You only need contrast — that is a grade, not a plate swap

How to swap the lid

  1. Import an outdoor clip with a visible sky
  2. Run Sky Replace and preview 1s/3s/5s on the worst pan
  3. Export locally if the horizon still reads as the same location

Frequently asked questions

Can this recover clouds that were never recorded?

No. It can replace the lid with a new plate, but it cannot invent texture that was clipped to white at capture. Preview the brightest section.

Is this the same as SDR to HDR?

No. SDR-to-HDR grades the whole frame. Sky replace is a dedicated horizon swap.
