Why would you assume that BOB is higher quality to begin with?
The API calls it adaptive, so i call it adaptive. :d

I'm a noob in deinterlacing, but that's what I found when googling: http://www.anandtech.com/show/1573/4

And indeed, I believe it looks better than what YADIF can do...I don't get a single artifact, yay! DVD's aren't so bad after all |

@leeperry: that articel dates 7 years back. The speech is about the "no motion --> weave fields" principle (pixel/area adaptive). Old & basic stuff, you see.

That said, there are DVDs with truly interlaced video, and even hybrid movies with some scenes interlaced and others telecined. Nvidia's post-processing tries to detect the cadence and pick proper filtering. It might work ok, but I guess neither output framerate nor the display refresh rate gets changed according to the content, so there's judder in 24p sequences.

There is indeed the 3:2 judder when deinterlacing IVTC material (which is far more likely on DVDs), but at least it'll be artifact free, even on mixed material (even mixed inside the same frame).

LAV CUVID Decoder 0.12
Code:
0.12 - 2011/08/19 - Improved response time on channel changes in DVB Viewer - Support decoding AVC1 with NALU sizes of 3 bytes The change about DVBViewer made it about instant for me (maybe a second of corrupted image until everything is fine), so i sure hope it works for you too. Not much more to tell, so have fun!

for the new build!

I am indeed talking about truly interlaced 29.97 NTSC video material running at deinterlaced 59.94fps in 59.94Hz(w/ Reclock), not telecined whatsoever. I can't stand judder and man does 59.94fps deinterlaced stuff rocks I don't bother w/ telecined stuff, especially considering that I'm from Europe and that PAL DVD's have a higher vertical resolution than NTSC....so in the rare cases where I watch DVD films, I just go 25fps@24fps in 48/96Hz w/ Reclock and there you go Last edited by leeperry; 19th August 2011 at 18:13. |

Which clocks are used is completely managed by the driver, if it decides to go into performance mode, then thats that.
You could try turning deinterlacing off, or toggling some of the other settings, to see if the driver allows it to go down then.

My Satellite card shows 100% quality on all these channels so it's not a quality problem. My satellite driver only shows 100% when any errors are fully recoverable, it only shows the true quality for example 72%, when there are uncorrectable errors in the stream. The latest build 0.12 still doesn't work for me so it could be my system that is to blame. It is getting old and due a re-install because a few things don't work correctly. It's like an old shoe, almost exactly how I like it, except for the few things not working. Spending hours re-installing is time I could better spend. However, it's unavoidable and has to be done in the next few days I do have other windows installs available on my main PC but most of those are older. Quote:
After doing so, I could not use any form of hardware decoding, either CUDA or DXVA. If I tried my system, which is also XP SP3, would either instantly hard lock or BSOD. It turns out that nVidia drivers, especially on XP, don't like updates because they don't remove the previous driver remnants. I had to uninstall them and then do use a driver cleaner to remove everything before re-installing. I now mostly works. CUDA appz work fine, DXVA works fine in MPC HC but doesn't work in LAV CUID because the video playback is partly corrupt. However there are not any BSOD's or system lockups Screenshot showing corruption Therefore I recommend that you uninstall and use a driver cleaner before re-installing. |

It is offtopic, but, I'll leave you with this thought. It's all well and good to say you'll stick with "tried and trusted XP." But, more and more things will not work on it going forward because they'll be written with W7, and soon W8, in mind. Just because some people choose to cling to ancient OS' doesn't mean the rest of the world does. Sure it "works" but when you do encounter problems, are you going to expect developers to work on fixing them? Right now that's not such a crazy idea, but, going forward, it's really going to be a waste of developer's time to try and keep supporting a 10 year old OS. Just something to think about. I'm certainly not trying to start a debate or flame war or anything like that. If you're happy with your OS, that's all good as far as I'm concerned. But, you're likely to see less and less support going forward. It's to be expected as tech evolves.

It's not an ideal solution, but Nvidia Inspector's Multi Display Power Saver tool (right-click the "show overclocking" button to access it) allows you to force the GPU into the lower clocked P8 (Video) power state rather than going into the P0 (Full 3D) power state with CUVID. It's a less-than-ideal tool to be using, but works for now, cutting my power consumption by 7W compared to CPU decoding. Hopefully Nevcariel can figure out why CUVID is kicking the GPU into the Full 3D P0 power state rather than the Video P8 power state. EDIT: Actually, this tool is awesome! Rather than adding mpc-hc.exe to the P8 Applications list, I have set it to activate the P8 state by VPU usage, and set that to 40%. (may need to experiment with this) With the HD videos I have tried so far, the lowest VPU usage for decoding has been around 45%, so this ensures it is not switching states in use. (that causes severe video stuttering) However, it lets the GPU run in the extra-low-power 2D mode (P12) with less demanding videos (e.g. MP4 off the web) which has dropped my power consumption with them to 92W compared to 103W in P8. For reference, my system idles at 90W. Last edited by 6233638; 19th August 2011 at 23:36. |

I was getting BSOD's and lockups when using any form of accelerated decoding on any player or application so it was nothing to do with LAV CUVID, it was only the nVidia drivers at fault. The FAQ only mentions corruption for XP which is what I experience when using it. It doesn't cause BSOD's! If you fix your drivers it won't happen. It is recommended that you reboot into safe mode to do the cleaning. |

I have just checked DGIndexNV and it's the same with that. With nothing else using the GPU, the clocks are all low, however by just opening DGIndexNV the clocks all jump to maximum, even with no video opened. Therefore it must be something to do with accessing CUDA that bumps the clocks to maximum. Not even doing any actual decoding affects them. |

It activates the P8 (Video) power state with HD videos, but for SD videos, it keeps it in the P12 (2D) state, which is just enough with my GTX 570 to let madVR perform the scaling I like (90% GPU load) dropping my power consumption a further 8W below DXVA. 92W with forced P12, MadVR/CUVID & SD video. 100W with EVR-CP/DXVA (P8) & SD/HD video. 103W with forced P8, MadVR/CUVID & HD video. 147W with standard P0 and MadVR/CUVID & SD/HD video. Before I also started throttling my CPU, my system's power consumption was almost 180W today, so I have almost halved my power consumption in some situations. (CPU was also going to full clockspeed on playback previously) |
