Encoding is usually a major, time-consuming event that occupied a great deal of time. Generally speaking, ripping a 100minsí DVD to Transformer optimized 720p HD mp4 can take up 2-8 hours based on the computer you use. How to shorten the DVD ripping process? I tested with 3 different settings and found that using proper settings with Pavtube DVD Ripper the conversion speed can be 6x faster!
