Have you ever gotten such experience that when you watch a piece of video or a DVD movie, there are dense misaligned horizontal lines on the screen that dramatically decrease the output quality? This phenomenon comes from a technical word called "interlacing".
Interlacing is applied to some earlier videos and DVDs. To make the output look smoother and more successive and reduce transmission bandwidth, the videos are split up into two fields to scan every single frame in the image - the first field contains the odd numbered lines and the second field contains the even numbered lines. All frames will be scanned one by one in an alternating way in the sequence of the odd, the even, the odd and then the even... In this way, successive footages are created.
The even lines and the odd lines
Modern displays only work in deinterlacing mode. To deal with some interlaced videos and DVDs, some DVD players and TVs are embedded with the function to handle the interlacing problem. But if your digital players have no such function, here is another way to deinterlace DVD once-and-for-all.
As I have mentioned above, the technical relic of interlacing badly affects the output quality of DVD videos.DVDs are based on MPEG-2 encoding, which allows for either progressive or interlaced sequences. It means DVD can be encoded as either progressive or interlaced. However, nowadays most DVDs are made in the progressive DVD form in which frames get scanned line by line from top to bottom. But what if you still wanted to watch old DVD films to recall some memories of your past ages? Then, it is necessary to find an effective tool to deinterlace those old DVDs.
WonderFox DVD Ripper Pro is a multifunctional DVD ripping tool that features a DVD deinterlace mode designed to remove misaligned horizontal lines during DVD ripping process. It can convert deinterlaced DVD to progressive digital videos in simple clicks. It supports all DVDs and can even deal with Disney movies. It’s simple to use this software.
