thin lines horizontally?
 
hey kwag i tried your 352x480 templates, and the pictures came out pretty good, but for one thing. i see a bunch of thin horizontal lines on the pc screen. do you know what im talkin about? would these lines show up on a tv?

Hi bizzy:

Can you try another source, and see if the result is the same?
Or maybe you encoded an interlaced source, and you're seeing a "combing" effect. That could be the cause.

kwag well i only notice the lines if i encode at 325x480,, when its at standard 352x340 no lines. the files is a dvdrip of supertroopers at 480x480 svcd.

while your on the subject of horizontal lines, I ripped a couple of deleted scenes of scary movie dvd :oops: and found that the vob files had horizontal lines is there a way to get rid of them??

I think the same issue applies here. You're probably seeing the interlaced lines. Try to de-interlace it while encoding it with TMPEG. Some scenes, specially extras and things like that, are 29.97 interlaced. They were not shot at 24fps. So if you want to put them on a VCD, you'll have to de-interlace them, because VCD's don't support interlaced mpegs.

cheers kwag will go and see if it removes them.

bizzy 07-20-2002 09:22 PM

did it remove them andy?

I done a little fiddling about with this, and found using the even field method of deinterlacing worked.

bizzy 07-21-2002 02:31 PM

so if its 29fps then that makes it interlaced? also does your template de-interlace the files?

You have to de-interlace either with TMPEG or with an AviSynth script.
