Interlacing artifacts when encoding with TMPGEnc

[get_thrashed]

I am encoding MPEG2 with TMPGEnc, and i am getting horrible interlacing artifacts. I am aware that these artifacts are to be expected when viewing it on a computer monitor, however these artifacts are also visible after i burned it onto a DVD and viewed it on my TV. The interlacing wasn't as pronounced, but it was there. Could this have something to do with the fact that I was watching it in 480p, and it couldn't deinterlace it? These are the pertinent settings for TMPGEnc I am about to use for my second attempt at encoding:

Video tab-
Frame Rate: 23.976 fps (internally 29.97 fps)
Encode mode: 3:2 pulldown when playback

Advanced tab-
Video Source type: Non-interlace(progressive)
Field order: Top Field First(field a)
3:2 pulldown-selected
Do not framerate conversion-selected

The source file is a 23.976 AVI, which i am fairly sure is progressive. Will these encode settings get rid of the interlacing? It still shows up in preview, but that is expected since it is a computer monitor(LCD, to be exact). Or is the problem because I was attempting to watch it on a progressive scan tv?
Thanks

I personally think it is related to resolution versus bit rate. try increasing the latter or lowering the former.

You've got your settings all wrong. Disable the 3:2 pulldown filter and the do not framerate conversion on the advanced tab.

Funny. I just came over to post about this very thing.

What I've noticed is that this seems to be an issue when the avi source file was encoded as interlaced, rather than de-interlaced.

I was wondering if anyone had a solution for this problem. I have tried encoding with 'de-interlace' checked in TMPGEnc and it doesn't help.

Should I re-encode the avi file to progressive and then convert to mpg? I hate to encode twice due to quality loss, but I haven't found any other way around it.

Any help out there?

Awesome, that seems to have done the trick, because I don't even see interlacing in the preview. Will the 3:2 pulldown flags still be set,though? I noticed that on my previous attempt, along with the interlacing the video seemed jerky, especially when the camera panned.

Sounds like you have the interlaced reversed. Interlaced video must be left interlaced for tv display, else you will be tossing out half the data and reducing quality significantly.

Thanks Lord Smurf. I'll try that and see how it looks.
