Have I got an interlace Problem? Re

[scjr]

OK, I am trying to region 1 DVD to vcd

The problem is that the picture appears to get distorted with horizontal lines around the movement on the video. And also occasionally on changes of teh frame... Like a mixed between teh previous and teh next. For ecample, switching from one shot to another.

I am not sure if theses are teh interlace problems I have seen discussed.

I am using SmartRipper to rib teh VOBs
Then using DVD2AVI to setup a project file for TMPENC to encode.

I cannot see these distortions in DVD2AVI, but when I open the Project file in TMPENC they are there.

DVD2AVI says its NTSC and 29 fps.

Whats the best way to get rid of them? I am not really wnating to play with various enconding techniques cos TMPGENC takes about 10 hours a go!


Appreciate your help guys.

Thanks

I should say I normally do PAL (Reggion 2) with no problems.

Its just on NTSC / Region 1 DVDs

i have the same problems with some of my vcd's, in some frames every 2nd line in the picture shifts to one side and then shifts back, and when changing from one whole scene to another i get the 2scene's all blocky and smudged together, its only for a few seconds but it would be nice if i knew how to get rid of them.

1) i believe for pal, you should turn forced film off

2) as for your region 1 dvd rip, since it is NTSC, interlaced...turn force film OFF in dvd2avi and use the NTSC template (not NTSC FILM template)....if you don't wanna use the template the main differences between the 2 is that...

NTSC NTSC FILM

FPS 29.97 23.976
3:2 pulldown no yes
interlace yes no
source video interlaced non-interlaced (progressive)

also, since your output video will be interlaced, be very careful about field order (my best bet is to encode a small bit and burn on cd-rw and then test on a TV, only works on TV cuz it won't make a difference on computer monitors)

btw, u only use FORCED FILM + NTSC FILM template if the video source is mainly FILM, progressive

field-order is irrelevant for vcd creation(exception is ivtc). 4 options are open to you for dealing with interlacing(in ascending difficulty)
-do nothing(resize will blend fields together), result: light ghosting
-discard field, result: crisp image, more blocky, no ghosting
-interpolate field(deinterlace), result: blurry image, no ghosting
-inverse telecine(not applicable for pure 60hz video), result: crisp image, no ghosting
