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.
