Why Do I Need to Deinterlace?
If you’re going to be ripping any significant amount of your personal DVDs, you’re going to come across interlaced video at some point. Many DVDs, usually older DVDs and TV series on DVD have interlaced video content. I’ve noticed this to be the case frequently with animated TV shows. If you do not take steps to deinterlace the video, you can wind up with a video file that seems to have strange horizontal lines in it during motion and action sequences. Most modern Hollywood film DVDs aren’t interlaced anymore, but I’ve encountered this problem frequently all the same.
