I moved this discussion to this new thread to stop hijacking the original thread where i posted this:

I realise this will be OT, but as you seemed to address this "frame pulse" issue i'll post here if ok.


I currently have this frame pulsing doing my head in. Basically, it happens to me on any codec content, whether it be mpeg2 (with or without DXVA), DV, H.264... using overlay or vmr9... SD or HD...

I've done tests on both my 6200 and my 6600GT cards, with drivers from the 9X.XX and 8X.XX series, both beta and whql and nothing seems to prevent this from happening.

On recorded content and live .TS content from DVB-T and DVB-S.


What i basically realised is that image is displayed in a wrong sequence.

For instances, let's imagine the right sequence should be:


A B C D E F G H


images (frames?) are actually displayed


B A D C F E H G


I've realised this by watching a video in slow motion when the jerking occurs.


Any help appreciated as this thing is driving me nuts.


(oh yes, btw, my setup: E6600, 2GB ram, p5b-deluxe mobo, very fast raptor hard drive...)

Hopefully NVidia will improve their drivers in the future, in the meantime I'm enjoying both broadcast HD and HD-DVD without any problems on my ATI card.

Jeeezus! I was reading so many wonders about nvidia's acceleration and video enhancement features... so i have 3 of their video cards - a 7300 on my laptop, a 6200 which jerked so i thought i needed a better one so went for the 6600GT... all of them have the same problems! This makes me really mad...

Yeah right, i won't trust nvidia for coming up with any solution whatsoever, from what i've been reading here and there...

Could you give any more infos on that?

There is no frame pulsing bug, because there is no "hardware" decoding/deinterlaceing.


I've got DScaler IVTC mod from this thread http://www.avsforum.com/avs-vb/showthread.php?t=596942

Dscaler 5 from http://deinterlace.sourceforge.net/dscaler5.htm

I set it up to use with MPC in IVTC "Always enabled" mode.

The only problem I've got with OTA HD movies and DVD is garbage in the DVD menus and some portion in the titles in the beginning of the movie, but I don't really care about that. I don't watch "video" material so I don't care about non-IVTC deinterlacing.



I'm running it on E6600/8800GTS system with Windows XP

Thanks for that, I will try your tip later on.


But what i'd like to understand is: why do i have the same frame pulsing "bug" when i'm watching a DV captured footage from my camcorder?

AFAIK DV isn't accelerated either...

All the Nvidia's I've tried (5950 Ultra, 6600GT, 7800GT) tear for VMR9 - unless I'm missing a vsync setting somewhere.




I have another question - is anyone with a late model ATi card successfully running 1080i via DVI (or HDMI)? My Radeon 9500 won't do interlaced over DVI (only VGA) - there's a few posts about it, it's a bug.




I don't want to spend $$$$ on a Nvidia to have it tear, but I don't want to spend $$$$ on an ATI and not be able to do 1080i over DVI....

 

[darkjedi664]

This issue is fixed in the 8800 100.30 Vista drivers.

 

[skepticon]

I don't think the issue is "fixed".

I think those premature Vista drivers just aren't using any hardware acceleration features, thus the problem doesn't manifest itself.

Best to wait until some "real" drivers are released before getting one's hopes up.

 

[stanger89]

Lastest drivers (93.71 IIRC) work fine on my 6800 using hardware accelleration.

 

[darkjedi664]

Um it IS using hardware acceleration as CPU jumps up without it. It IS fixed as it doesn't happen on the 100.30's and it DID happen on the 97.92's on XP. My settings are EXACTLY the same as it is on XP, just using Vista and the 100.30 drivers.

This is good news! I am also affected by this problem, and I do hope they fix it in XP drivers - I am not planning to move to Vista soon.

 

[barth2k]

I don't know what people mean by "pusling" but when I use nvidia purevideo decoder to playback mpeg2 1080i TS it doesn't look right. Slightly jerky and more noticeable motion blur. I know it's in use b/c the icon shows in the tray and CPU utilization is lower (20% vs 40% on elephant's dream TS). But s/w decoders, even MPC's internal mpeg2 decoder, look better.

 

[kamaleon]

Hang on folks,


I'm getting this with NO hardware acceleration, i'm not using Vista or a 8800 gpu...

 

[jerrytdss]

8800 using 97.92 drivers certainly has frame pulse with windows XP.


Real waste of money for a high end card to have such problems.

Can you remind me, are you using PureVideo decoder?

 

[barth2k]

is frame pulsing when the screen seem to blink on and off during playback (esp. during horizontal pan) like an old film print?

 

[Jarretth]

I haven't noticed this. I have a 6600GT OC AGP. I'll go grab a DVD and try to play it back in slow mo if you say it appears in the wrong order.

 

[Jarretth]

Ok I did just that with a few scenes in 12 Monkeys and the intro where some of the credits scroll from right to left. Did it frame by frame. No frame seemed to jumped back and the credits text definitely did not jump back for a frame. It should be obvious if it's out of order right?
