Recreating Sky

On a recent grade I was faced with sizeable number of clips who had blown out sky and that needed to be made look good. If the sky is just peaking through in a few places, bringing down exposure and adding some color may be enough. But if the sky is prominent in the shot the lack of any texture will be glaring.

For one clip in I went down a more complicated path and it was worth it because it was one clip the client upon review called out as being beautiful.

This is the final clip, nicely highlighting the parrot in full color:

This is what the original footage looked like:

 

This type of work is beyond what can be easily done with Resolve and effects. So I used Fusion Connect to bring this clip into VFX software where it's easier to layer different parts together. The first step was to put a luma keyer on it to isolate the blown out sky:

 

Then I used the DaySky tool which can create a natural looking sky by date and latitutde/longtitude. But it's a blue sky with horizon color distortions. For a bit more realism I threw in some fast noise to create moving clouds, do some color tweaking and merge it with the keyed clip:

 

A little color and exposure matching in Resolve, a tracked vignette on the main bird, and things look a lot better...
