NVIDIA PureVideo Technology

Thread Starter 
Has anyone heard of this before? I just found out about it and thought I would let everyone know. This will enable hardware mpeg2 decoding on the NV 6 cards namely the 6800 and 6800 ultra cards. It no only helps with the CPU usage but also helps with video quality!!!
I haven't had much time to try it or anything but I thought it would be cool to hear about other peoples experiances with it.

I found a reivew of it here


and here is nvidia's offical page about it


Sorry about my Sig I haven't had time to make it smaller yet!!

i started a thread about this. For some reason, it wouldnt work for me. When i went into WPM, all i get is a black screen when i try to play the dvd. From wat i hear, its pretty nice.

To play DVDs you still need the nVidia DVD Decoder.

I think you need a 6xxx series GPU to use it's features.

PureVideo is on all of nVidia's 6 and 7 series cards, including mobile ones. There is no PureVideo software, it's activated by the latest drivers. The PureVideo decoder is actually nVidia's DVD Decoder, and if I recall correctly, it only works with PureVideo enabled cards. All PureVideo cards have SD accelerated decoding of MPEG-2. You just need a DVD decoder to view MPEG-2 video. The problem is that nVidia crippled MPEG-4/WMV9 hardware accelerated decode on some early 6 series cards. But that function is fixed in later 6 and 7 series cards.

i purchased the NVidia Purevideo Decoder Platinum a few weeks back and the quality of DVD movies is really quite impressive. The images are without doubt, crystal clear. CPU utilisation is lower becuase the graphics card offloads the some of the processing requirements. To tell whether your system is using the purevideo decoder, during dvd playback in WMP there should be a NVidia logo in the right side of the taskbar. if u double click it, u can customize the colour, the video setup and the audio setup.
I would highly recommend purchasing the decoder to anyone with a 6800/6800 ultra GPU. if u are still unsure, i believe NVidia offers a 30 day free trial. After the trial ends, u will not be able view DVDs in WMP and you will only see a black window. To view DVDs again, ull either have to purchase the decoder or uninstall the NVidia Purevideo Decoder.

this sounds a lot like XVmc which linux has had for a long time.

Just some further facts for everyone...
Purevideo IS Nvidia's DVD player. They no longer offer any other DVD applications/solutions. If you purchase the decoder, you can use Windows Media Player to view DVD's (and get the additional Purevideo quality benefits if you have a Geforce 6 or 7)...or Windows Media Center edition. I run Purevideo on both (WinXP and WinMCE)...and the results are outstanding (on a 6600GT and a 6800Go).
Purevideo WILL work with other cards as well (such as ATI)...but you will not get the benefits that Purevideo offers over the other decoders out there. PowerDVD or ATIDVD would be a better option for ATI users until ATI releases thier - just announced this past week - "Avivo" software, which is ATI's competition to Nvidia's Purevideo.

We need to differentiate between PureVideo technology and PureVideo Decoder. They are two different things that work together, but two different things nonetheless. PureVideo is much more than just a DVD decoder. It is circuitry built into the 6 and 7 series cards that offere hardware acceleration of the decoding of HD/SD MPEG-2, MPEG-4, and WMV videos as well as hardware acceleration of post-processing effects of the same. The PureVideo decoder aids one small, albeit most important part, of the PureVideo technology - MPEG-2 decoding.

and ya, the pure video logo comes up in the taskbar when i run it, just no movie, black window. Maybe it diddnt register correctly, as someone up there said after the trial ends you see a black window...

I'm waiting for my XPS-2 with a 6800 Ultra in it to be delivered.
As a non-expert about this item I would ask you to explain me what this thread is about an what could be the benefit.
I've understood somehow that is can play some video and that calculating by the CPU now can be done by the GPU, but that is all I did understand.
Do I've to purchase anything to make it work fine?

Note: I'm very much interested in DV-editing.

Isn't this a scam or somethin... Nvidia's tryin to make more money off something they should've given us for free as purchasers of their video card since PureVideo is part of the card but won't be enabled until u buytheir crap.

I install the Nvidia Pure Video Decoder the latest version but iono see the deocder option. I don't see it in start menu or 6800 ultra desktop property tab. I check the directory and all i see is this D:\NVIDIA Corporation\ForceWare\nStant Media. nstant Media? where's the decoding option ?

snazzy gen2 - When you watch a DVD through Windows media player...you will see a nvidia icon in your taskbar. Right click on that to adjust PureVideo properties.

Nvidia's Purevideo decoder is no longer a stand alone DVD player (like PowerDVD, WinDVD, etc)...it is just a decoder. You need to use WinMedia Player or WindowsMCE to adjust its properties.

Envinyatar - I second that! This thing should be free with the purchase of their cards!! ATI has been bundling thier DVD software with their cards for ages. Although, they too will probably start charging for thier new one when it is released. Ugh!

This may help for those feeling a little confused about what Purevideo is:

Ok.
That makes sense.
Only two question remain:
1. Can you use PureVideo with the latest NVIDIA Geforce Go 6800 Ultra videocard? I've read somewhere that the new ones are ready to use it although the AnandTech review sais it otherwise.
2. Is it any help to use PureVideo in DV-video-editing?

The 6800 Ultra the review mentions is different to the 6800go Ultra, Purevideo is broken in the 16 pipeline desktop 6800 Ultras but as far as I'm aware it does work for the mobile variant, someone may correct me on this though.

It won't help with video editing, Purevideo is to assist with the decoding of videos, not encoding.

Based on this thread, I aquired and installed NVidia Purevideo Decoder and I have to say, it's pretty nice.

I used to have a $20k overhead CRT projector, a 10'x6' Stewart Filmworks screen, and a Camelot Roundtable DVD player, so I've seen some pretty nice DVD performance. I can definitly see a difference in smoothness and image quality between NVidia Purevideo Decoder and PowerDVD 6, which is was I was using before. I can't speak for WinDVD.

BTW, remember to check out the nVidia icon in the systray (it's not in the task bar) to fine tune your settings.
