Help on capture quality,pls!!!

[dilco]

I am new to the forum and have read a lot of the posts and think that there are many experts here.

I am capturing from a DV sony cam using an integrated capture card that comes with the GEForce3. I have downloaded all the recomended software and currently using VirtualDub to capture.

When I am previewing in the monitor the quality is flawless. When I capture and look at the files there are strange lines that appear when there is fast motion. If the scene is not moving that much, the capture is excelent but as soon as there is a rapid movement of the camera, this lines appear on the edges of the persons or objects.

Is there a way to improve or get rid of this effect. My videos are really clean as they come from DV. I have tryied capturing at 59 fps, 720x480, compresion, no compresion, and every other setting. I dont have problems of HD space/speed or anything like that. I am not even loosing frames, just this effect.

Thanks from Mexico

I assume you see these "lines/edges" playing back on the PC. In that case, you are most likely seeing the results of displaying interlaced video. If the PC is your prefered viewing platform, then you need to de-interlace your video. If you intend to burn them to VCD or DVD to play in a set-top player, then you should leave it interlaced as it will look clean once displayed on your TV.

G-man, thks for your reply. You are right. I have been capturing and watching in the computer. What I want is to make some SVCD (no dvd writer) of my home videos. My DV has excelent quality and I want to get it exactly as it is onto the TV. I think that for that I need DVD burning.

Is it possible to really get the same qlty that the DV cam has ?

I tryied deinterlacing to view my video in the computer and I am still getting the edge lines. I am going to burn a sample video to see if it disapears in the TV. I am using virtual dub with hufy.

What would be the best settings to make an SVCD ?

Do you loose qlty when going from AVI to MPEG ? In my first trials, when watching in the tv there where small squares all over.

I really appreciate your help as I am as Newbie as someone can be and beeing from Mexico is more difficult to get help.

It's preferable NOT to di-interlace truly interlaced materal. If you do you will be loosing up to 50% of the video signal. Movement and fine horozontal detail will be the most affected.

The one big trick to doing interlaced materal is getting the feild order correct. Basicly if it's off movement will be jerky ( 2 steps forward one step back, 2 forward one back ... ).

No, since the DV uses a low compressio on 720x480 data. SVCD can probably match 70-95% of the original depending on how clean it is.
