UPDATE - PureVideo MPEG-2 Benchmark

[otispunkmeyer]

this film seems speeded up for some reason...infact win dvd appeared to be speeding up all my dvd's (ie like 1.5 speed or something) so i picked PAL truSpeed and its fine, but this still plays like its being slightly fast forwarded

and yes.....if they ever get encoding out the door....and hopefull by that i mean Mpeg4/divx/xvid ill be well happy

Unfortunately, I have little to no hope for encoding support on any of the current cards.

Maybe they'll promise that the G70 can do it, and then never speak of it again after launch...same as last year. :roll:

I can't play the video at all... what codec is needed? I have WMP10 but no nVidia decoder... my trial expired.

*EDIT* Nevermind... using WinDVD.

jeff does it appear to play in something slighty faster than real time on Win DVD?

HA! To prove a point, laptops generally suck... ATI Mobility 9600 w/ 1.6 Pentium M... I get about 10 frames, then loss about 5, then 5, then loss about 5, then 10...

I wonder if your laptop HD is holding you back more than the low clock speed of the P-M? Especially if you have a 4200rpm drive....

It is also WinDVD4, by default, on the playback. The drive does not go to a sustained light, but it does spike. I could put a Perfmon disk performance monitor on it, but that requires a reboot IIRC and can interfer with the performance. The spikes on the drive light do not seem to correspond with the stops. I thought we had spec'ed these mobiles with the 5400 and tried to go to 7200. That was over a year ago and a different position, so I just don't remember.

Nope... looks fine. Fraps shows 60 fps exactly at all times.

that's probably irrelevant. normal (real-time) play:

Frames displayed: 1,2,3,4,5,etc...

Sped up:
Frames displayed: 1,3,5,7,9,etc...

Yet it's still running at 60 FPS. Chances are it's just his PC though.

I've also got to think there is something seriously wrong on the WMV HD acceleration front. I wish someone would come clean with the real answers because users are being treated like stooges, and Nvidia isn't the only player on the hook as far as I'm concerned. It smells like a conspiracy to me, but what utter nonsense to the whole video enthusiast community.

It's my understanding that DXVA support is implemented via the WM ASF Reader filter (when correct connections are initiated). ATI/NVIDIA has yet to add the support to their GPU's DXVA, or "PureVideo".

Aaagh, yellow fever! Run! Several decoders exhibit that so mayhaps it is an encoder fault.

Radeon with Cyberlink decoder
sans HWA: 27% CPU
avec HWA: 12% CPU

Which why I don't understand why each is waiting for Microsoft to update WMP10 when it appears to me from reading MSDN that they would only have to build their own player software and licence DRM from Microsoft to provide WMV acceleration and DRM support for commercial WMV (HD) playback. WMV acceleration has been available since DX9 was released what 2 years ago (IIRC)? something smells.......

Not to be too skeptical, but GPUs have had MPEG2 decoding assist for quite some time, so I'm not sure how this proves the PVP's worth. Does that checkbox enable/disable the PVP specifically, or simply GPU decode assist in general? Actually, does the GF6 even have the previous gen's MPEG2 decode assist h/w in addition to PVP, or did PVP take over all de-/encoding? (Most importantly, why don't I know this for sure a year after the GF6's launch?)

Do you have a link of a clip of that NASA vid? I was wondering if someone could try it with another card, be it an FX, a (my?) 9800P, or an X800.

I'm not sure if it disables the regular DXVA or not. What I think is that it does, and the regular DXVA shows some decrease in CPU usage also. I'm guessing the Elecard filter was using DXVA and gave me CPU usage inbetween that of the completely unaccelerated and PureVideo-accelerated NVIDIA fliter. So, PureVideo is like twice of the plain old DXVA that's been on cards forever. This is all just speculation though.

Yeah, here's the link: <a target=_blank class=ftalternatingbarlinklarge href="ftp://ftp.cmf.nrl.navy.mil/pub/iHDTV/andrews_18.mpg"><a target=_blank class=ftalternatingbarlinklarge href="ftp://ftp.cmf.nrl.navy.mil/pub/iHDTV/andrews_18.mpg">ftp://ftp.cmf.nrl.navy.mil/pub/iHDTV/andrews_18.mpg</a></a> Beware, it's 569 MB.

Anyone else have a reaction to this, or just don't care about PureVideo?

Purevideo acceleration is pretty nice. That andrews footage was quite possibly the nicest video I've seen on any hardware that I actually own. Looking forward to high def DVD playback. Unfortunately most (all) DVDs I own aren't encoded in 1080 format, but the digital cleanup purevideo provides still makes for a bit better picture. So now the question is at what point will my 7800 GTX become obsolete where I can justify moving it to a dedicated HTPC. Probably about the time I can actually convince the wife that we "need" a bigscreen HDTV.

ddogg, that is the most USELESS comment I have ever seen.
