Using Handbrake to Convert AVI Files to MP4 1. Download and install Handbrake on your computer from http://www.handbrake.fr/downloads.php/ 2. Open your video file in Handbrake. Under “Output settings” click the drop-down menu next to “Format” and choose “MP4 file.” Click the drop-down menu next to video codec and choose “H.264.” 3. Click “Picture Settings” in the toolbar. When the picture settings window opens click the drop-down menu next to "anamorphic" and choose “Loose.” Next to the “Width” option, click the down arrow until the width value is at 480. This will match the Android’s default resolution. 4. Click the “Target size” option next to the “Quality” section of the Handbrake window. Set this to the desired file size. This value will most likely be determined by the amount of storage that your Android device has. 5. Click “Start” in the toolbar and wait as Handbrake converts your video. 480 x 320 is the default resolution of most, but not all, Android devices. Keep this in mind when converting. If your device has a higher resolution, set the width value to the width of your device's resolution.
