You can use the Movie Maker feature of Google Earth to record 3D viewer imagery and save
the recording as a movie file. You can either set the recorder to record your
interactions with the 3D viewer in real-time, or you can set up a tour and record the
entire tour without interruption.
Once you finish recording and have saved your file, you can make the file available on a
web site, use it in a presentation, or send it via email. For instance, you might want to
create a movie of your property to present to clients or at trade shows where visitors
can see satellite views of your property without having to use Google Earth.
The Movie Maker feature supports different movie file
formats:
-
Windows Media Video (WMV) - (Windows and Linux only) This output file
format is compressed and optimized for presentations. These WMV files can be further
configured for the best type of delivery, such as via a T1 web connection or over a 56K
modem connection.
-
Audio Video Interleave (AVI) - (Windows and Linux only) Movies created
in AVI format are uncompressed and as a result, generate extremely large files, making
it almost impossible for a standard movie player to play back the recording. This is
useful only if you want to edit the movie clips using a movie editing software.
-
Image Stream (JPG) - Movies can be captured as images in variable or
fixed length. This format is useful if you want to control the speed artificially and
edit each screenshot (frame by frame).
-
QuickTime - (Mac only) Movies can be captured in Apple QuickTime .mov
format.
Movie Quality Levels
The Movie Maker feature also supports two types of movie quality levels:
-
Standard quality movie (real-time) - Use this option when you want to
adjust the visibility of icons and overlays while the movie is recording. For example,
use this option to display an overlay of a site plan or additional layers of
information as you record. Keep in mind that with this option, the frame rate is
limited to the performance of your graphics card, which is generally slowed by making
movies.
-
High-quality movie (tour-mode only) - In general, high quality
recordings work best when you want to display the movie on a large screen. Use this
option to achieve the best possible movie recording. With this option, each frame is
completely downloaded to the Google Earth client before it is recorded, maximizing
image quality. For this reason, recording time is comparatively slow. Unlike the
standard quality movie, you do not need to monitor the actual recording of the movie.
Note - Keep in mind that high quality movies can only play back tour
points. You cannot manually interact with the 3D viewer when using the high quality
option.
Tips for Recording Movies
This section covers a number of tips to help you create quality movies. We recommend you
familiarize yourself with these tips before beginning your recording in order to produce
the best possible movie for your needs.
Note: The time slider is not
available when you record movies.
Update Your Movie Player
Having the latest version of Windows Media Player or Apple QuickTime installed is
absolutely essential to making good quality movies, especially if you are having issues
with the graphics quality of your movie. We highly recommend that you download Windows
Media Player 9 or above:
http://www.microsoft.com/windows/windowsmedia/player/9series/default.aspx
Or for the Mac:
http://www.microsoft.com/windows/windowsmedia/player/mac/default.aspx
You can find the latest version of Apple QuickTime here:
http://www.apple.com/quicktime/
Update Your Graphics Card Driver
Although graphics card drivers have no impact on the actual recording of your
movie, a faulty graphics card driver can produce anomalies in your 3D viewer that then
transfer into the movie itself. Therefore, it's always good practice to update your
driver to avoid any possible rendering issues. We recommend that you use a graphics card
with at least 64 MB of video RAM or above.
Increase Your Memory Cache
By increasing your memory cache size, your movie recording experience will go faster
(although it will have no impact on the final quality of your movie). To increase your
memory cache, see Memory and Disk Cache
Preferences.
Increase the Detail Area of the 3D Viewer
Increasing the area of detail for your 3D viewer helps to capture all the pixels in more
detail. As a result, the resolution of your movie is improved. See Viewing Preferences for instructions.
Note - Set Detail Area to Large if you have 64 MB of
graphics card memory or more. If you have less than 64 MB of graphics card memory, set
Detail Area to Medium.
Adjust the Touring Speed
When recording, it is best to use a relatively slow tour speed. However, feel free to
experiment with different speeds and then play the movie back to evaluate whether the
speed is appropriate. See Touring Places for details.
Note - The tour speed you choose will be consistent throughout the
movie. If you want to set different tour speeds for different Placemarks in the same
movie, you will need to create separate movie files for each tour and then edit them in a
movie making software.
Adjust the Elevation Exaggeration
If you want to enhance the appearance of terrain in your movie, you can adjust the
Elevation Exaggeration as described in Viewing Preferences.
Showing or Hiding Items in the 3D Viewer
To hide or show the compass, status bar, scale legend or grid, simply uncheck or check these items in the View
menu. Likewise, in this same menu, you can check or uncheck Atmosphere to hide the
atmosphere around the globe when viewed at full horizon or from space. See also:
Preview Your Tour Setup Before Recording
It's a good idea to set up and review the tour points you want to visit in your movie.
This involves two simple actions:
- In the Places panel, select either an entire folder to view all the
placemarks within it, or select individual items in the folder to view only selected
ones. See Touring Places for details.
- Click the Play button that appears below the Places panel to play
the tour. This tour is the same tour that will be followed if you use the High
Quality Movie option, so you can have a sense of what your movie will look like by
playing the tour. See Touring Places for details.
After previewing your movie, be sure to make any adjustments necessary before recording.
For example, if you want to change the view of a particular placemark on the tour, you
can always right-click (CTRL click on the Mac) on the placemark, then select Snapshot
View in the menu. This will overwrite your existing placemark view. See Editing Places and Folders for more details.
Set Up Your System for Maximum Efficiency
Making movies is a memory-intensive and graphics-intensive process. It's best not to have
multiple large applications running on your computer during recording. Disable both
screen savers and pop-up blockers.
Steps for Recording Movies
Follow these steps to record your movie:
- From the Tools menu, select Movie Maker. The Movie Maker dialog box appears.
-
From the Supported Compression Formats selector, choose the desired
compression format for your movie.
If you want to have a movie format other than WMV (Windows Media Video) or .mov
(QuickTime), check the Advanced checkbox and choose the format. If you choose
another movie format, only standard AVI compression is available. Note that AVI formats
are not compressed and therefore will result in large files.
-
Select High Quality or Standard Quality as the movie
quality. See Movie Quality Levels for details.
-
Choose the Frames Per Second (FPS) you desire for your movie. The
highest FPS setting, 60, offers the smoothest movie viewing experience, but at
the cost of a large file size. For instance, if you want to record a 800 x 600 movie at
60 FPS, you will not achieve the best results. In this case, choose a lower setting in
order to produce a smaller file. The lower the FPS setting, the more jerky the movie
will be. You'll want to find the best compromise between frame transition and file
size. Typically, a setting of 30 works fairly well for movies that you want to provide
over the Internet.
-
Choose the resolution for your movie. You'll want to choose a
resolution that is appropriate for your final movie display. For example, you might
have a computer screen projector that only supports a 800 x 600 format. You can specify
the following resolutions, which indicate the width and height of the movie in pixels:
- 320 x 240
- 640 x 480
- 800 x 600
- 720 x 480 (NTSC) - This setting works well with large screen displays.
- 720 x 576 (PAL)
- 1280x720 (HD)
- 1920x1080 (HD)
-
Specify a name for your movie. Click on the Browse button and
navigate to a location on your computer where you want to save the movie file when you
are finished recording. Type in a name for the file in the file dialog box and click on
the OK button.
Alternatively, you can select an existing movie file in the same format as the one you
are about to create, and that file will be overwritten with the contents of your new
recording.
Note - If you are recording your movie as an image stream, it's best to
choose a new filename or folder location rather than overwriting an existing image stream
selection.
-
Click the Record Tour button. The button is available only
after you enter a valid filename for your movie. When the movie begins recording, the
Movie Maker dialog box appears below so you can visualize the recording of the movie.
Note - Recording time in high quality movies occurs very slowly, since
each frame is fully processed before the next one is viewed.
When You Are Finished
When you are finished the steps of recording movies, to stop
recording, click the Stop Recording button in the Movie Maker dialog box. Once
you finish recording your movie, you can open the movie file in a media player that
supports the movie format you selected and play back the movie to view the results. If
you are satisfied with the results, you can post the file to a local server or use it in
a presentation.
