Lots of thin, horizontal lines ???

[Cappy]

Question......It seems that no matter how I encode the video ripped from a DVD, the output MPEG has tons of thin, horizontal lines during any kind of movement in the video (if it's still, it's perfect)....especially when the person or object moves fast and leaves a motion blur....that motion blur is FULL of thin lines. But it's not limited to just that...but with any kind of movement....I'm stumped. When I've created SVCD's from high quality DivX or Xvid's.....no problem. The VOB's ripped from the DVD are clean, without this problem when viewed in DVD2AVI or the like. I don't know if it's an encoder issue (TMPGEnc) or DVD2AVI.....which is what I used to create the MPEG2 out of the multiple VOB's. I've used various settings in the encoder....but its always the same. Also the MPG looks this way even when just viewing it on the computer before making the SVCD or VCD. It is NTSC and according to DVD2AVI's info, the DVD is recorded in progressive mode.

Any ideas or suggestions would be greatly welcome.


Thanks,

Cappy

I have not experienced it myself but...

If you do a search under "horizontal lines" you will find some references.

Some users are suggesting that you need to deinterlace.

I don't know if that's the solution or not but try the search and see for yourself.

yeah it sounds like you need to deinterlace. Sometimes dvd2avi says a video is progressive if the intro video stuff like the fbi stuff and rating for the movie is progressive, but the rest of the movie is interlaced, usually if you preview the movie, it will show you that the actual film is interlaced. Try deinterlacing, that would be my primary guess.

The divx and xvid files are fine because they have already been deinterlaced to be able to run fine in their native cpu format which is progressive.

Try converting the DVD with DVD2SVCD. It might be able to detect the prober de-interlace or IVTC settings for you.

Its the easiest way (and still a very good way) to do DVD to SVCD conversions.

What program are you using to rip the video?

[Cappy]

Laddydaddy......I used SmartRipper.


Mordant.....Guess I'm going to have to read one of the guides for DVD2SVCD....not too familiar how to use it

Thanks for all your help.....I wasn't sure if those were actually interlace lines or not......I'm fairly new to this svcd/vcd thing

I'm not sure if this will help but make sure the demacrovision box in smart ripper is checked. And in TMPG got to settings and then look at the advanced tab. Make sure the video source says non interlace. If all else fails frame serve from virtual dub and use the deinterlace filter. Use the blend mode (the default setting) and see if that works.

Download a program from the tools section called Eazy Vcd it will do the lot for you, nothing fancy, just gets the job done.

Cappy, you might not even need a guide for DVD2SVCD. It's a very simple to use program.

Install DVD2SVCD, start it up, point it to your copy of TMPGenc or CCE in the encoder tab, put the DVD in your drive,pick your source, hit "go" and you are set...after you've tried it once with the default settings you can look into playing around a bit with bitrate/resolution/audio ect...

do you see the lines when you actaully author the disc and play it on a set top?

Sometimes certain s/w and players show the interlace, which goes away when watching it on TV from the disc. (the tv knows what to do with the interlace)

this problem haunted me until somebody said "burn the disc and then see." sure enough...
