2. You may choose an existed profile from the "Profile" dropdown list to modify.
Resolution-----our program will auto-keep original aspect ratio of a DVD. If the original DVD is a
full-screen movie, it will use 320*240 to rip the DVD while 368*208 for wide-screen movie. If you need to
re-set the resolution, you should set the right aspect ratio. For example, you should set 4:3 like 640*480 for
full-screen movie and 16:9 (or 1.78:1) like 640*360 for wide-screen movie.
Video Bitrate/ Audio Bitrate-----They are key factors
to affect the quality of ripped file. Usually the higher the
value, the better the quality. But in MPEG-4 codec
specification, the highest value of Video Bitrate is 2500
while Audio Bitrate is 256. And in H.264 codec
specification, the highest value of Video Bitrate is 1500. So don't set a value over this
restriction, for it's no sense for improving quality.
Video Codec-----We support both MPEG-4 video codec and H.264 codec. The former will save much time
and quality is perfect. Usually this codec is appropriate. If you care much about the quality and don't care of
the time and file size, you may choose H.264 codec.
