Deinterlacing really bad (1 Viewer)

[Glajda]

Hi.

I'm having trouble deinterlacing TV programs. It doesn't matter what codec or method I choose in Mediaportal, it looks awful.

On the other hand, VLC doesn't have that problem, so I'm wondering what I have to do to correct this.

My system is Athlon 64 3500+, 1GB RAM, Geforce 6600GT, so no hardware acceleration is possible.

Try a few different codecs, if you have Cyberlink's powerdvd codec try that as it de-interlaces well without hardware acceleration. FFDShow can also give good results but you might need to tweak the settings.

So if I understand correctly it's not enough just to set the interlacing method in Mediaportal, but I have to set it in the codec itself? If so, what do I set in Mediaportal and does it even have an effect?

 

[miroslav22]

I'm not 100% sure but I think most modern codecs handle the de-interlacing internally and output a progressive picture to the renderer. So if this is the case the MP option shouldn't have any effect. One of the devs might know more.

This is driving me crazy.

Nothing I set seems to work. As if all deinterlacing settings are ignored. I've tried setting it in ffdshow and MP, but the picture is not deinterlaced.

On the other hand, any method I set in VLC looks O.K.

u are saying u want hardware acceleration without having hardware acceleration

does not compute

VLC uses its own propietry codecs not accessable by directshow and MP..thats why it looks different

i use the lowest card that supports hardware acceleration ..the nvidia 8600 gt ..it has a passive heatsink for no noise and it does anything MP asks of it

if u want to buy a new card ..id recommend an nvidia 220 gt ..there are silent ones of that card with a low profile

also look at my codecs in my sig

I never said I wanted hardware acceleration.

I'm saying in Mediaportal deinterlacing doesn't work at all. I can't test it with another program but VLC, as it's a TV stream.

What I would like to know is what do I have to set to get deinterlacing working.

im so sorry..

hardware decoding = deinterlacing

im not sure what format your tv comes in as..here in australia its mpeg2 ...so the microsoft DTV video decoder (which comes with Windows 7) is perfect
if ur using h264 format for tv ..then id recommend CoreAVC 2.0 (its costs $10 but its in my option the best h264 decoder out there)

 

[Glajda]

The TV is in mpeg4, which doesn't have extra settings in MP (could this be the problem?).

What codec is used for mpeg4 decoding?

I've tried ffdshow, Microsoft and MPC codecs, but can't get deinterlacing to work.

 

[SiLenTYL]

mpeg4 isnt a video codec

if you can get ur hands on coreavc 2.0 its well worth it for h264..which is probably what your tv is if its not mpeg2

from the nvidia wiki page (i see ur using the 6600 gt)

Starting with the release of the GeForce 6600, PureVideo added hardware acceleration for VC-1 and H.264 video, though the level of acceleration is limited when benchmarked side by side with MPEG-2 video. VPE (and PureVideo) offloads the entire MPEG-2 pipeline (except the initial run length decoding, variable length decoding, and inverse transform),[2] whereas first-generation PureVideo offered limited VC-1 assistance (motion-compensation).

The first generation PureVideo HD is sometimes called "PureVideo HD 1" or VP1, although this is not an official NVIDIA designation.
