During vhs capture with several different capture programs, I experience horizontal tearing of the image on the preview screen. This appears to happen only when there is a high contrast vertical object in the video. In my case, it is happening during a video shot from inside an RV. When the video includes the RV's window (where there is a vertical center strut), the video will tear in horizontal around the strut. Actually, it appears as if horizontal synch is being lost (?). I've tried both avi and mpeg2 capture with same results. Other portions of the tape capture just fine. Could it be that this will not be a problem after burning a dvd and playing to a tv? I'm capturing directly to my graphics card using composite video input. The tearing also appears in playback of the avi or mpeg2 file on the pc. Haven't yet attempted to burn. Thanks for your help - great forum! Bill Asus A7N8X MB AMD XP2500 Asus V9180 capture card (latest drivers) 1GB RAM
What you are Talking about sounds Like Interlaceing, When you capture at Full resolution the Video is Captured is Fields of Horizontal Lines, there are 2 Fields per Frame and there are 240 Lines per Field and these 2 Fields Put together make up the Frame, What you are seeing is Most Likely the artifacts caused from the seperation of these Fields when Viewed on your Progressive Monitor.... You PC monitor is not made to display Interlaced Video Content and that is why you are seeing these Interlace artifacts, You should not see this effect when Viewed on a Normal TV set, and there are things you can Do to Minimize this effect..... Try captureing your Video to AVI in the Highest resolution(720+480) and quality Possible Like useing the HuffYUV codec which is a Lossless codec so there is no quality loss because of Compression but you will need a Lot of Disk Space, about 30gb per hour... After captureing your AVI file you will still notice the Lines but now you use a Mpeg encoder Like Tmpgenc to encode the File to Mpeg2 for DVD but go into the advanced settings and select the "De-Interlace" filter, and go through the Filters till you find the one that best Gets rip of the Lines, Tmpgenc has a Choice of about 16 different deinterlace filters, Usually the best filter is the "Even Field" or the "Odd Field" or the "Double Field (Blend)" setting, Once you have chosen the best looking filter encode the File to Mpeg2 for DVD and after encodeing watch the Mpeg2 file and you should notice that most if not all of the Lines have disappeared......Cheers
