New Nvdvd decoders WOW!

[Jeraden]

Mine are probably pretty old, I'd have to check when I get home. I remember updating them last when Doom3 first came out to fix some issue in it.

[dagar]

Yeah, I'm running latest. Could be the problem (big shock!), too bad I don't have time to work on it now.

[stanger89]

For those of you who haven't made the jump yet

nVDVD 1.00.58 (4.00.58 decoders)
Geforce 6800 (fanless) 65.90 Quadro FX 4000 drivers (inf swap)
VMR9
1776x1000i (46")

Enjoy

[SHS]

Say Stanger89 where did you say you live at I want come over and get you GF 6800 from you that look pettey good

[stanger89]

I think it would be cheaper for you (gas money) to just buy one yourself, what with it being a 16 hour round-trip drive and all.

Oh, and for all those doubters out there, all I did was:
Install the video card drivers
Set them to High Quality, 2xQ AA, 16x Anisotropic filtering
Install the decoder pack
Set it to Hardware accelleration, Smart deinterlace control, and Pixel-Adaptive
Play

I know I'm trying very hard to save up for one thoses bad boy

Stranger89,
how is the 6800 noise-wise?

[stanger89]

The one I picked makes none (note the fanless comments)

I'm running the 4.00.29 version from Aopen and I was wondering if there is a way to disable deinterlacing? I output via S-video to a 480i display so there is no need for deinterlacing on my setup.

I'm also having severe tearing problems with horizontal motion and I'm wondering if it's caused by the deinterlacing. The only decoders I've found so far that pretty much eliminate it are the cyberlink decoders that come with PowerDVD. From what I've read I should be able to get better picture quality from the NVDVD 4.0 decoders but so far that's not been the case.

I'd like to purchase the full version of NVDVD, but I see no point unless I can resolve the tearing durng horizontal motion.

Any help would be appreciated.

Thanks,
Rob

set deinterlacing mode to weave in SageTV
and that will disable deinterlacing

I see combing when I do it

and that does look really nice Stanger

running NvVPP with VMR9 and looks really good
a little more grainy though than your picture as I can tell that NvVPP is sharpening the picture

Even when set to 480 lines, most video cards don't scanline match between the lines on the desktop display and the interlaced TV-out, so the video displays on the desktop as progressive (requiring some deinterlacing) and then the desktop display lines will be smeared across the TV display lines in the 2 interlaced fields, What you are probably seeing is the interlacing artifacts from 'weave' deinterlacing... (try 'bob')

Thanks for the info. You see combing whwhen you do what? Turn on deinterlacing??

I don't really think it's artifacts. It's most noticable in scrolling text such as on the bottom of CNN or another news channel. With the Cyberlink decoders the text is crystal clear, but with NVDVD decoders it is very blurry and almost unreadable. Also, when an object moves horizontally across the screen there is very bad combing and the object will leave a 'trail' behind it.......

yep those are definatel interlacing artifacts (see www.100fps.com for more examples)

Cyberlink decoders in the default auto select mode use bob for interlaced MPEGs and Weave for non-interlaced MPEGs (in my experience with PDVD-XP v4.0, YMMV!) Bob displays each half-frame field scaled up to the full frame, so that you do not get the 2 half-frames shot at different time intervals overlapping each other which you would do in Weave
eg a box moving across the screen will be shown as follows in Weave:

+------------+
     |#########|
|#########|
     |#########|
|#########|
     +------------+

Which is why scrolling text and horizontal panning looks so bad!

Did you notice a big improvement over your prior video card? What was your prior card and did you try the same decoder/settings with it? I've been debating going the 6800 route or waiting for an XCard interface. If I go with the 6800, there's no way I could justify the XCard later. Thanks.

Thanks so much for the help! So what would be the correct method of setting the deinterlacing properly? Do I set it in the properties for the NVDVD decoder or from the 'detailed setup' in Sage? In the NVDVD properties the only deinterlacing options I see are 'best available', 'display fields separatley' or 'combine fields'. In Sage I see the options for Bob, Weave, etc.

Thanks again,
Rob

My prior card was a Radeon 9500 non-pro. I'm not going to say it was a huge improvement, pretty much all the recent cards (DX9 class) are pretty good. However it was an improvement, but it would be hard to quantify. The one HUGE difference is that I can run VMR9 now.

I guess I could try to be specific (FWIW, I could be imagining things):
Things seem clearer now.
Red seems less orange.
No VMR9 tearing
Things seem somehow smoother, almost like Trimention DNM but not hokey.

I suppose the the best way to sum it up would be to state that I find myself smiling when watching it now, where with the 9500 I found myself being frustrated most of the time (VMR9 tearing, Overlay colors out of whack, this, that, the other thing).

I'd say if an HDTV is in your possesion or your future, then the 6800 (or 6600, 6700) is a good choice. I briefly hooked up the S-Video (when I had some connections backward and couldn't get the RGB output working) and it looked clear and "vivid" but I never played any video on it.

There's two things you can do probably (all of these are in the nVidia decoder properties unless specified):
1) Set Deinterlace control to Video and Deinterlace method to combine fields, that should replicate what you get with Cyberlink.
2) (this is what I'd do)
2a) If you have a Geforce 5 or 6 series - Set Hardware accelleration to on, set deinterlace control to smart, and deinterlace method to Pixel adaptive (VMR9)
2b) If not - Set Hardware accelleration to off, deinterlace control to smart and in Sage select nVidia Video Post Processor.

I'd try 2, it should give you pretty to really good deinterlacing so you aren't piling interlacing artifacts (from the S-Video output) on top of deinterlacing artifacts.

Thanks, I'll definately try both ways and see what gives the best results. I'm actually running an Nforce2 motherboard with on board Geforce4 MX graphics so option 2a probably won't work.


Also, will choosing Overlay, VMR7 or VMR9 have any noticable efffect on the video quality?

-Rob

[stanger89]

Yeah, your MX doesn't have the advanced deinterlacing stuff the 5 and 6 series have. As for VMR7/9/Overlay, yes it will make a difference, Overlay or VMR9 will probably give you the best picture, which one of those is better will probably depend on your hardware and preferences.
