Creating MPEG4 Video Files
Select Source & Destination Files
In the example above, a source file 24 hours of Lemans.avi has been selected as the
source video. You can see on the bottom of the window its original characteristics
(width 720, height 576, frame rate 30). Next, you must then tell the program where to
place (Set Destination file) the newly recoded version of the file (don’t worry, it will not
erase the original). You should give it a new descriptive name, such as shown above
Lemans AV300.avi. Make sure you add the .avi extension.
Change Settings
Next, you can change the parameters
(Change Settings) of the DivX™ encoder to
adjust the level of quality of the final 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.
Target & Priority
You should select the target as AV300. 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 file that is 800x600
in resolution and 30 frames per second, this
is beyond the maximum resolution that the AV300 can play. Thus, the MPG4 Translator
program will have to decrease the resolution, the frame rate, or both. If you prefer that
the resolution of the image is kept to the largest maximum, then click on the Priority
control Resolution. The best possible resolution will be kept and the frame rate will be
decreased in order to accommodate that resolution. On the other hand, if you want to
make sure you keep the highest possible frame rate, then click on the Priority control fps.
The highest possible frame rate will be kept and the image resolution will be decreased
to accommodate keeping the higher frame rate. You can also see what the size and
frame rate will be by looking at the Video Image Size: Destination parameters. The LCD
option should be chosen if you would like the video to be encoded for best playing on
the built-in LCD screen of the AV300. When choosing FPS or Resolution, it is understood
that the output will be optimized for a television, and not the built-in screen.
