mpeg2 linear effect (picture included)

[4321]

This is present in pretty much all of my mpeg2 clips.

A linear blurrish thing when objects are moving. Is there any way to get rid of this effect?

I noticed in my player, mpc, it converts the viewing ratio to 4:3 (my goes with my monitor), and that effect is gone.

From that I'd assume I just have to convert the resolution to something that goes with 4:3 and I should be good to go?

I don't know how and why this works/happens.

Thanks.

search for "interlaced" or "interlacing" etc.

OK I looked up the interlacing thing. And I tried disabling and de-interlacing the clip in tmpgenc. It didn't work, I still get that effect.

I take it tmpgenc just isn't good enough and I'll need to use some other program? I've only got tmpgenc and virtualdub. Would it be possible to de-interlace it in xvid or something with virtualdub?

The clip, btw is in mpeg2. Is recording off the TV always interlaced? Seems everyone who uses mpeg2 has it interlaced. When I convert it to xvid, it's still interlaced.

before you try to destroy the interlacing, please consider what you want to do with this video...

if it's going on a DVD, please for the love of elvis don't deinterlace it. simply determine what field-order it is, and tell that to TMPGenc or whatever you end up encoding with (TMPGenc is good, but there's free and better stuff out there, like HC or QuEnc).

as for determining field-order, it's pretty easy:

- if it's DV, it's probably bottom-field first. DV is stupid this way and it's caused no end of problems for everyone.
- if it's anything else, it's probably top-field first

that means your clip (TV cap) is almost certainly top-field first - all digital broadcast equipment using SDI uses this (even DV recorders if they use the SDI interface), and hence all TV _should_ be top-field first, unless you recorded it off air with a DV device.

those assumptions work 99.9% of the time, and when it doesn't work you'll see it when you play on a TV - jittery motion. if you get this, just try again with the other field-order.

also note that when you play it in MPC, it's doing a deinterlace on it's own - the motion should be very smooth this way. what's happening is it's reading from your source file that the video is interlaced and that it should bob-deinterlace it during playback. xvid can also do this if you encode it as interlaced and set the correct field-order, though for low bitrates (sub 1000 kbps or so) it's probably best to deinterlace.

Hi!And I tried disabling and de-interlacing the clip in tmpgenc. It didn't work, I still get that effect.Which mode of deinterlacing did you set by:

TMPGEnc>>Setting>>Advanced>>Deinterlace

and did you put a checkmark in the box next to "Deinterlace"?

Yeah, I went to settings, checked that box. then I tried it again. Didn't work so I played around with the other options.

like the video source type, i set to non-interlace. and encode mode in the video settings to non-interlace as well.

none of them worked at all.
