File Types and Characteristics VIDEO
|
As you may know, there are quite a few different types of video file formats (.avi, .mpg, .mov, .ram...). Most all video files that you will use are compressed. To decompress these files, the computer must have the information necessary to know how to decompress (reassemble) the file so that it appears as intended. This information is in the CODEC. When playing many types of videos with the Windows Media Player, you will notice that it searches for the codec. Many times, it's unsuccessful. If this happens, you can often still play the file but you must manually install the codec. Before you can install it, you must find out what codec is needed. At this time, the G-Spot Codec Information Appliance seems to be the program of choice for determining the proper codec. The following image is a screen shot from this software.

On this computer, the proper codecs are installed. If the proper codes were not installed, it would tell you which ones you need. From there, you could use Google to find them on the net.
