Change Settings

Next, you can change the

parameters (Change Settings) of

the encoder to adjust the level

of quality of the fi nal image. Like

MP3 music, the higher the bit rate

setting is made, the higher the quality of the music, or video in this case,

that you will get. However, this will also take up more space on your hard

disk. A setting of 900 kbps will give you a nice looking image for viewing

on a television. For near DVD quality, you can set it up to 1200 kbps. If

you do not use the standard version, uncheck the bidirectional encoding

in your codec property page.

Target & Priority

You should select the target as

Gmini

402. You will see a Priority

box appear. This control is to

allow you to select which feature

of the video to be guarded. If for

example you are re-encoding a video fi le that is 800x600 in resolution

and 30 frames per second, this is beyond the maximum resolution that

the Gmini

402 can play. Thus, the MPG4 Translator program will have to

decrease the resolution. Choosing LCD optimizes the fi nal video format

for viewing on the built in LCD screen. Choosing the TV option will

optimize the movie to keep the highest possible frame rate. You can see

what the size and frame rate will be by looking at the Video Image Size:

Destination parameters. When choosing TV, it is understood that the

output will be optimized for a television, and not the built-in screen.

Start

Click on

Start and the program will call Virtual

Dub to start processing the video. Depending

on the power and speed of your computer, this

could take real time (a 60 minute long video

re-encoded in about 60 minutes) or much

longer. As shown to the left, you will see the

progress as it processes the video fi le. If the

Start button is grayed out, it would be for one

of two reasons. 1) The source fi le is not a true

AVI fi le. Even if the fi le name ends with .avi,

the internal fi le data determines if it is truly an AVI fi le. 2) The Virtual Dub

program was not located when MPG4 Translator was started up. Close the

program, restart it, and make sure you locate the Virtual Dub program.
