Many home video cameras record a movie on to MiniDV tapes. MiniDV tapes are very popular digital video containers. They still have been used and many people keep storing their home videos archive on this MiniDV tapes.

Sometimes, when the time makes bad artifacts on this MiniDV tapes it is good for us to make another and more safeness archive on our videos. To do this we have to make capture of the video from MiniDV tapes and save in some video files on CD, DVD, Blue-ray or any other digital video containers. After the video from MiniDV tapes is fully captured, we will have large 13Gb video file for each hour of video. Next, when we play already captured raw video especially when we stop the video on pause, something in the paused frame make our eyes to be disturbed. Like in the sample picture showed bellow, we have seen jagged lines on the edges around moving people or objects. Is this artifacts a defects in our video?

No. This is just the Interlaced video.

Interlaced video means that all even fields are displayed in one frame and all odd fields will be displayed later in next frame. In NTSC - 30FPS (Frames Per Second) video system this mean that in each second we will see 30 fully frames, separated on 60 semi-frames - 1 frame for even fields on current frame and 1 frame for odd fileds on the next frame. In PAL video systems frame rate is 25FPS.

In modern video systems, like HDTV standards this problem is resolved with progressive video - all fields (even and odd) are saved in one frame.

In this tutorial I will show you How to Deinterlace Interalced Video.

To do this we will use free video processing program - VirtualDUB.

First, open the video in VirtualDUB. Next go to Video / Filters menu.

Next, click on Add... button and select Deinterlace filter from the list. Check for Deinterlace properties by clicking on Configure button. Best results can be obtained with Blend fields together for Deinterlace mode. Now click OK, OK.

Now, when you start the processing video from File / Save As AVI... menu, VirtualDUB will clean out this jagged lines from our video like shown on the picture below.

Now your video is Deinterlaced and you will know How to Deinterlace all your Interalced Videos.
