Viewing videos is a processor intensive and hard drive demanding process. Large video files require higher end machines. To view videos we suggest the following minimum requirements:

Abbreviation Resolution Size Download Time (DSL) CPU RAM Hard Drive Speed
1X 200x150 < 50 KB  < 1 seconds   200 MHz 128 MB 10 msec
2X 400x300 100 KB 1-2 seconds >200 MHz 256 MB 10 msec
3X 600x450 150 KB 2-3 seconds >200 MHz 512 MB 10 msec
4X 800x600 200 KB 3-4 seconds >500 MHz 1 GB 10 msec
5X 1000x750 400 KB 6 seconds
 1GHz 2 GB  8 msec
6X
1200x800
 800 KB
9 seconds
 2GHz  4 GB
 7 msec
  5X and 6X are planned when Echo goes to HD quality.

I can't see the videos once they are downloaded.

        In order to see the videos you must have the correct plugin and the correct codec installed. The videos in this web site are QuickTime videos. Go to www.apple.com and download the latest QuickTime player. The correct codec should be installed along with the QuickTime player. If not, you can download the correct codec from www.sorenson.com. The codec we use is Sorensen3. If you have installed (and reinstalled) the above files then make sure your screen resolution is at least 800x600 and your color depth is 16 bits (thousands of color) or better. Slow machines (< 500 MHz) machines may not play the larger videos correctly due to the videos large size. The large videos require a fast hard drive, lots of RAM, and a fast CPU. Try the videos on another machine to see if you need to upgrade your machine.

 

I can see lower resolution videos but I can't see the higher resolution videos.

How are the videos named? (Video Naming Convention)

   The video list uses a naming convention to allow you to search for the type of video or animation you wish to find very quickly. The naming convention uses a format developed by the ASE and SCA. The file name uses the standard ASE/SCA format so be sure to save the files in their own separate directory or you will overwrite the files of the same name. Each directory contains the abnormality-severity text.

  probe location - probe view - echo mode

  An underscore _ is used between each parameter. For example, if the probe located in the mid esophagus (ME) and the probe view was a 3 chamber view (3CV) and the echo mode was pulse wave doppler (PWD) the file description would be:

          ME_3CV_PWD

The following table shows the naming convention abbreviations and their meaning:

Why do the videos appear darker on a LCD monitor or a portable computer?
 
LCD monitors on home desktop systems or portable computers have decreased contrast when compared to CRT (big, old) monitors.  Because of this decreased contrast the videos will appear dark.  Try decreasing the ambient lighting (view them in a dark room) and turn the contrast and brightness on your monitor to maximum.
 

Why are the videos on my Apple/Macintosh machine darker than a Windows machine?

 
Because of the method Apple/Macintosh's display images and videos, the images and videos will be darker than on a Windows machine.  Try decreasing the ambient lighting (view them in a dark room) and turn the contrast and brightness on your monitor to maximum.
 

Why are the popup videos not popping up or not playing?

 
The popup videos (when you click the 1X,2X,3X,4X links) may not popup correctly if you have anti-popup windows software installed.  While the anti-popup or anti-ad software works on popup ads, it also prevents our web site from popping up windows.  Most of the anti-popup software will have an exception setting which allows popup windows to occur from a "trusted" web site.  Please enable this setting by adding our web site www.e-echocardiography.com to the "trusted" section.
