If you have some video fi les that do not play directly on your Gmini
™
500, they will have to be converted fi rst.
Windows Media
®
Player 10 (Available only for Windows XP) will convert your video fi le automatically when you
sync the fi le that is on your PC to the Gmini
™
500. It will display a little message ‘converting’.
You can also use the software MPEG-4 Translator included on the Gmini
™
500 hard drive to re-
encode your video fi les into the proper MPEG-4 SP format that the Gmini
™
500 can play. See the chapter
Video – creating MPEG-4 video fi les with your computer for more details.

How to create an MPEG-4 video fi le
Video fi les that come from your digital camcorder, sent to you via e-mail, or which are freely available on the
Internet are encoded in many different ways. If not already in the proper MPEG-4 Simple Profi le or WMV9 Simple
Profi le format, a transformation operation must be done in order that these video fi les can be played by the
Gmini
™
500. This transformation process is called re-encoding.
There are basically two ways to do this: 1) Use the Synchronize button in Windows Media
®
Player 10 or 2) Use
the PC tools which are available on the Gmini
™
500’s hard drive. The fi rst method is very simple and merely
requires that you synchronize a video fi le in your Media Player library to your Gmini
™
500. You do not have much
control in this converting process though and Windows Media
®
Player determines which video types it will and will
not re-encode. The second method, though it requires some learning, will allow you to have much more control
over the fi nal quality of the re-encoded (converted) video fi le. It is described below. There are other tools available
on the Internet, some free and some for sale, that can also convert your video fi les into the appropriate MPEG-4
SP video fi le format for the Gmini
™
500. See the web site www.mpegmobile.com for a list of a few of them.
PC Tools
The Gmini
™
500 is delivered with two Windows
®
based programs that allow you to create MPEG-4 Simple
Profi le .AVI video fi les. They are the MPEG-4 Translator and Virtual Dub
™
. The MPEG-4 Translator will call the
Virtual Dub program and give it the correct parameters to encode your video from its original format, .avi or .mpg
(mpeg 1), and then encode it into an MPEG-4 SP .AVI fi le. The fi le will be scaled in order to be played back
properly.
