@Landey was pretty close, below is how I would do it in Davinci Resolve:
- Get the lot plan and convert it to PNG, no other image format would work properly. You will need to convert it to a PNG with transparency. I would convert it in something like Paint.Net but getting high quality results would take a long time, ideally, they would submit it to you as a PNG already.
- Film the site with the drone but pay special attention to the clips where you plan to overlay the lot plan. For those clips keep the drone very slow and steady, no fancy movements.
- Edit the video like normal (titles, callouts, audio track, etc).
- Go back and for the clips that will have the overlay create a new Fusion composition by right click > Open in Fusion
- This will place the video clip to a background node and link it to the Output
- Create a new merge Node and link it between the output from the background to the output for the video
- Make sure the video clip is linked to the background input of the merge node then add a new Transform node do the foreground of the merge node
- Create a new tracker and track forward and backwards through the video clip
- Take the results of the tracker and feed them into the transform node
- Add the overlay to the input for the transform node and properly scale the overlay to the footage in the clip
- Play the whole thing forward and backwards to test it out.
You will now have the overlay properly tracked to the background drone clip. I have overly simplified a few of the steps you will probably need to also do some corner pinning and possibly will need to use a 3D tracker if you want Z axis movement, but those are the basics.
If you are not familiar with nodes in Fusion then this will be nearly impossible to complete without many hours of studying and practicing in Fusion using online tutorials. Also, the integrated Fusion performs very poorly performance wise so be prepared for a lot of frustration as it renders.
BTW if you want to know exactly how they did it in the sample video all they did was use overlays in the
Google Earth Desktop app, they placed the drone in very stationary points at certain locations onsite, then added the overlay to the video footage and did a crossfade transition from Google Earth to the video footage. All of the fancier motion was done in Google Earth which made the job much simpler than trying to corner pin, 3D track, etc.
The whole project probably started as a KML file and they used a
KML to PNG converter to import the file into their video editor.
