view the videos and animations in this web site you need the Quicktime
plug-in for your web browser.
I'm using Microsoft Internet Explorer for Windows v5.5 (SP2) or v6.0 (or
above) and I can't see the movies, what's wrong?
These versions of Internet Explorer for Windows no longer support Netscape-style
plug-ins. We have added new HTML code to our Virtual Site pages with embedded
Quicktime movies that will prompt you to load something called ActiveX
Control for Quicktime from Apple. Once you have loaded this piece of software,
then the movies should work with your browser. Just visit one of the Virtual
Site pages first to automatically load this software.
this does not solve the problem, and you are getting the following error
message: "This page provides potentially unsafe information to an
ActiveX control. Your current security settings prohibit running controls
in this manner. As a result, this page may not display correctly",
then do the following to change your security settings within Internet
Explorer in order to see the movies:
Go to the "Tools" menu and select "Internet Options".
Next, choose the "Security" tab at the top of the window that
opens, then click on the "Custom level" button. Within that
window click on the "enable" radio buttons for all the settings
within the "ActiveX controls and plug-ins" group of options.
Then click OK several times and that should enable your browser to play
the Quicktime movies.
I'm not using Internet Explorer, but I don't see the fly-through movies
or the panoramas on the Virtual Site pages, what's wrong?
The Quicktime plug-in is not loaded properly on your computer. Go to the
web site and follow the installation instructions. If you have
done that and are still having problems, try rebooting your computer (to
reload the registry) or check with your system administrator (sometimes
loading new software on networked PC's requires administrator privilege).
The movie windows show up on the Virtual Site pages, but they seem to
take forever to load, what's wrong?
The NeMO Explorer web site has been designed for relatively fast internet
connections. The movie and panorama files on these pages are relatively
large (0.5-1.5 Mb) and the videos run at about 60Kb/sec, so if you have
a slow internet connection (slower than DSL) it may take a long time to
fully load the fly-through movie and panorama on the Virtual Site pages.
As an alternative, relatively fast internet connections are available
at many public libraries and schools. We may make versions of these pages
for slower connections in the future.
The panoramas don't seem to work properly, what's wrong?
If the panorama does not show up at all, make sure you have the Quicktime
plug-in loaded properly for your web browser. If you can see the
panorama scene, note that the panorama files must load completely before
they work properly. The files are large, so if you have a slow internet
connection it may take a while. The Virtual Site panorama files are 0.5
to 1.5 Mb each, and the panorama of Axial caldera is 3.2 Mb. The panoramas
give a 360° view of each site. Click
and drag your mouse inside the panorama window to look in different directions.
The buttons in the bottom left of the panorama window zoom the view in
or out and show embedded hotlinks to video clips. In the ASHES, CASM,
and Marker 33 Virtual Sites clicking on ROPOS will move you to a different
location within the scene.
The fly-through movie starts and then stops, or doesn't play at all, what's
Again, make sure you have the Quicktime
plug-in loaded for your web browser. Also, the fly-through movies
must load completely before they play properly. The files are large, so
if you have a slow internet connection it may take a while. The virtual
site fly-through movie files are 1.0 to 1.5 Mb each, and the fly-through
movie of the 1998 lava flow is 4.2 Mb.
