A "good" light-painting mission will have many waypoints - perhaps 100
Once a suitable light-painting mission has been created, save it in
Litchi's Mission Hub. Export this mission as a CSV file named something
like "painting.csv". The exact GPS location of this mission may need to
be adjusted and re-exported later.
This mission will be used to view the progress of the light-painting
To create this mission, one might place a POI centered at the location
of the light-painting mission at a height of roughly one half that of
the light-painting mission. In the example provided, "Spiral Mission
Maker" was used to create a spiral around the location of the
A "good" viewing mission will also have many waypoints - perhaps 100 or
at least a number of curved turns.
Using Virtual Litchi Mission, export this mission to Google Earth Pro
and then right-click on the mission in Google Earth Pro and save it
(Save Place As...) as either a KML or KMZ file. Name it something like
"view.kmz" or "view.kml".
Navigate to the light-painting mission area, orient the view to be looking straight down, and zoom out.
Use the "Add Image Overlay" tool to import the black image created earlier.
Open "Add Image Overlay" tool.
Browse to find the black.png or black.jpg file created earlier.
Make sure the "Altitude" is "Clamped to ground".
Grab the corners of the image overlay and drag them way out to cover any nearby terrain.
Drag the KML file downloaded from the "Light Painting Simulator" into Google Earth Pro.
Google Earth Pro should orient the view to show a completely black display.
Turn off all layers except for "Terrain".
In the View menu uncheck "Atmosphere".
From the Tools menu select "Movie Maker".
Record from "A saved tour:" select the dropdown list and choose "Run Virtual Light Painting...".
Note the location of the "Save to" setting and change if necessary.
Set the "Picture size (pixels)" appropriately.
Set the "Frames per second" appropriately.
Select "Create Movie". It may take a few minutes to generate the light-painting movie.
If you notice the display of any terrain, return to the "Add Image Overlay" step, modify the overlay to cover more terrain.
In Davinci Resolve: (I use Davinci Resolve. If you use different editing software, it probably has similar functions.)
On the "Media" page, add both the actual viewing footage and the Google Earth Pro movie.
On the "Edit" page, drag both clips into the timeline. Place the Google Earth Pro movie on top of the actual footage.
Select the Google Earth Pro clip.
In the "Inspector" window, change the "Composite Mode" to "Add".
Adjust the starting points of the clips relative to each other as appropriate.
The remaining steps depend upon your workflow.

From the "View" menu, enable "Atmosphere".
In the "Layers" window pane, enable "Borders and Labels, Roads, 3D Buildings, as desired.
This utility can be used to augment reality by combining a simulated light
painting mission with the actual footage of a viewing mission creating an
interesting combination of real and synthetic drone footage. Two missions
The light-painting mission is one that is used to draw the shape of
a recognizable two or three-dimensional object in the sky.
This mission does not have to be flown. Instead, it will be simulated.
All that is required is the Litchi CSV file of the mission.
The viewing mission is one that will be used to view the progress of
the light-painting mission. This mission will need to be flown with
a drone to capture the actual footage.
Virtual Litchi Mission data will be combined with light-painting mission
data to create a simulation video that can be composited on top of
actual drone footage.
Perhaps the best way to understand what can be accomplished with this process
is to view the example video displayed to the right. The following tools will
