TV picture quality

[mc2wheels]

I am not seeing CPU usage dropping when using "smart" deinterlacing, and checking the "hardware acceleration" box, while using the nVidia VPP. Perhaps I need a newer nForce driver, but I am using the latest non-beta. I have heared that there are fixes for the VPU in the latest driver/nvdvd codec that has not yet been officially released.

Well, technically there is nothing from the FCC regarding HDTV broadcasts. The switch in signal type will be from the current analog signal to digital signals (DTV). DTV is a collection of I think 18 different standards for digital signals, three of which are actually considered HDTV. I think 2006 was just the target year that they were throwing around, but the actual target is when 85% of households have DTV capable TVs / Cable Boxes.

...could be a while...

I too have noticed this issue. If I select the VPP it says it's using software mode. Unfortuantely I cannot use the regular Nvidia Decoder. The brightness fluctuates from dark to light every 2 seconds. I don't know if it's the drivers (using the latest beta), the codec (waiting for the update to come out) or if I have a defective card.

Well this has got to be the dumb question of the day. I have the 5200 and the nvidia encoders but I cannot find these properties. I know the decoders are available because Sage can see the Nvidia decoder and the VPP and I can select the VPP although there is much stuttering.

They do not show up in the control panel (sounds and audio/video codecs) and all I seem to have on the desktop is the Nview desktop manager but I can't seem to find where allows me to set the properties of the video decoder.

In the past I've used the pvr-350 but I am trying to learn the ropes on my 5200 before I spring for a better video card for my new HDTV.

peace . . .

check the registry the is a key that can enable and disable the tray icon
it should beeasy to find
it will be the in the nvidia software section

think local machine

[mc2wheels]

If you choose nVidia codec (not the vpp) from within sage, it will not show up in the tray. Not sure why, but when I chose default codec in Sage, then I get the nVidia codec, and the tray app appears and can be modified.

It is less now that I went back to DirectX 9.0c, but it is still there. It is also less noticeable with Digital vibrance off or low. I am hoping that the latest dirvers for the card and the latest codec will fix this. I want to try the "pure video" functionality with my 6600GT anyway, and the only way to get it will be with the 70.3 beta driver and 1.00.67 codec.

It's actually the 67.03 released driver.

Now that there is an NVDVD trial, I have had a play around...
I still see much less contrast and color definition when using VMR9 or VMR7 ("default" on XP) renderers than using Overlay (but of course, I cannot screen-capture overlay).

Interlacing wise, I get best results when using the Nvidia Video Decoder (*not* the VPP), using Smart deinterlacing and. hardware acceleration enabled... The easiest way to test this is to find a channel with scrolling text, or a lot of horizontal movement.
The easiest way to *set* this up is to select the VPP, play something, use the tray app to change the settings, then go back to setup and select the Nvidia video decoder. Alternativly, use Graphedit (in the Filters section) insert the DirectShow filter, and right click it to get the properties page.

As soon as I select the VPP, scrolling text looks bad again (in this case, smeared)...

I have also seen the field order problem after seek in VMR9 (using Ms' Graphedit tool!) Again, this is obvious with scrolling text -- it is clear, but stutters across the page...

So, for me, Overlay is still way better than VMR9 -- semi-transparent text is just not worth the disadvantages!

Nielm- I lusted after the transparency of vmr9 but loved the quality of overlay until v2.2.2. Now with overlay I get the best of both worlds. Pretty slick.

agreed, I always use RTL5

Also in my case overlay gives a better (moving) picture on my monitor, but I cannot get overlay picture on my TV. Is that the same with you, niel? And if you do get overlay on TV can you tell me how you get it?

are you using an ATI video card if so thats the reason that NvVPP does not look good
but I also have seen the double text on scrolling text
I thought they were going to fix this
but I still get the best picture other than this issue with NvVPP
and overlay looks awesome with the NvVPP

[jan smit]

I have FX5200 and also get better (fast moving picture) with non-VPP

[kny3twalker]

have you enabled smart deinterlacing ?

[jan smit]

have you enabled smart deinterlacing ?

yes.

In case my previous question got lost:
How can I get a picture on both my monitor and on my SDTV (svhs TV-out), when using Overlay? My TV stays dark.

[kny3twalker]

you need to make the TV the primary monitor and you will probably not get video on both monitors and why would you want it ?

if you use VMR7 default or VMR9 you can get video on both TV and monitor
but I doubt either will playback smoothly on both at once

a FX 5200 is not going to cut it for more than a single display and certainly will not do VMR9 nicely on a computer monitor
but on the TV using svideo is should be ok

the 5200 is a base line video card and I would not expect to run dual monitors off it

[jan smit]

Thank you kny, that makes sense.
I'll see how it goes with TV as primary.
Also I'll have to look for a better AGP card. My local shop does not yet seel AGP 6600 but has for Xmas an attractive deal for 6800LE. Would it be wise to take that or is it much better to wait for a 6600 for slightly more money?

In the (near?) future I want to replace my SDTV for an LCD 32", but first I need to be sure that I can watch sports without interlace problems.

[kny3twalker]

well the 6600s have component output and WMV HD accleration
where as the 6800s are a little faster but are limited to mpeg acceleration

I would wait until the LCD TV is bought
they will hopefully have better cards then or these will be cheaper

the 5200 should do better with just the TV showing video
do not run a clone on the pc monitor
run dual monitors

have not watched any sports yet
but everything looks really good so far with pure video of the 6xxx series

[jan smit]

Well, I tried setting monitor and TV in Dualview with overlay and TV primary but that wasn't a succes: now I didn't get a desktop on my monitor (just a blue screen). Going back to Clone was not easy since my desktop on the TV is hardly readable and since TV and PC are in different rooms, my remote mouse could hardly make the distance.
However I am back at Clone again.
I think I take your advice and wait for the 6600. I suppose that a 6xxx card is prerequisite for Pure Video (?)

One (last?) question: I read on the forum things about setting AA and AF, etc in the driver (whatever that may do), how would I do that? Do I need FFDshow ore Zoomplayer for that?
