Set Up

For the best result, here are some things you can do when recording a movie in Google Earth

1. Close all other programs - Reduce strain on the computers processing power by closing Photoshop, Final Cut, Adobe Premiere or After Effects

2. Restart Google Earth - To clear the caches and improve recording speed, especially if the program has been running for a while

3. Clear the caches - Go to 'Options/Preferences' and then 'Cache'. Clear both memory and Disk caches

4. Disable any unused Layers - Uncheck any layers not necessary, such as Roads, Ocean or 3D Buildings

5. Be sure the tour controls are 'off' - Click the small 'X' in the top right to close. With the tour controls on, you will be unable to open Movie Maker

6. Set anisotropic filtering to 'High' - In the Preferences, 3D View. This will help recording performance.

7. Codecs - here are the results of a test with the Codecs available by default in Google Earth Pro. All movies were recorded in 1920x1080 resolution and 30 frames per second:

Animation provides the largest, most crisp file and leaves you with lots to work with in post. 

These settings should remain after you restart Google Earth. It is a good idea to check after you restart to be sure everything is set up properly.
