They are jerky and I have yet to find a proper way of making this smooth.

I got it smooth

So first im using Aero on Win7 2nd im using Intel HD2000 currently so no Nvidia currently the setup that got me the smoothest motion result is

MPC-HC 64 3706

Lav splitter->Lav Audio->Lav Video->EVR (Normal) all MPC-HC Internal Sync functions disabled



I didn't achieved smooth hardware playback yet

You get 24.27 fps on a 29.97 movie, and you call that exact frame rate?

The file is really tricky though. It seems to have its interlacing or telecine completely screwed up, EVR doesnt manage to deinterlace it properly.

Hi nev,

If the file is improperly encoded it would be a shame though...
I mean, if you regard it as unsuitable for deinterlacing/panning tests?
Perhaps something happened in the process of me extracting this part for a small clip.
Is there a way for me to give you these details from the main file? It is 5,4 GB in size...

I can tell you that with CUVID I have absolutely zero combing with the 25/30 fps setting and just no/minor combing with 50/60 setting.

In any case... do you experience the "panning" issue too? The trees "lagging" (I am not sure which word to use) even if there are no frame drops and the rest of the contents are smooth (to the eye at least)?

edit: My setup is added to my signature now.

Apparently the signature doesn't get added after a post is made (some boards do this). Signature should be visible now.

Yes i know but the tree pan is smooth and it still seems sync (and it goes more towards 25 fps even might be indicating that it was actually recorded @ 25 fps from the start, nothing uncommon to use a 25 fps cam and later convert to 24 or then because of broadcasting to 29) i made a video of it but it's not as smooth as in reality on screen (recording overhead)

But im surprised that i dont get smooth results with the MS DTV-Decoder and DXVA CPU utilization is much lower @ arround 4% but the smoothness is more bad compared to the 10% Cpu Utilization LAV Video needs for this but absolute smooth on the 4 I-5 Cores and Power Consumption isn't that much higher i would have expected even higher latency because of the multithreading but Win7 seems to be very efficient here compared to XP also the Power Config (Balanced) doesn't interfere in anyway Performance wise

@nev
it seems the smoothnes on EVR (normal) compared to EVR Custom comes from the Interlace Flag sending in Lav Video turning it on on EVR causes problems for the tree scene turning it off results in that 24.xx smooth playback though on Evr custom you have to turn it on again and then it fails with smooth playback resulting in some 39.xx fps It's interesting on EVR you dont seem to need to send anything it will get correctly deinterlaced and telecined by the hardware regardless. EVR custom seems to lose that ability currently this could maybe also explain the behavior on my sample.ts (which is also telecined it seems)

Also my major guess is you see those 24.xx fps on EVR because Intels Hardware is doing some good adaptive work here

Hehe i found a way to get it smooth with Lav Video (Send Interlace Flags) also on EVR Custom being telecined correctly :P this is really funny but forcing DirectVobsub to be loaded makes this possible

Hi, nevcairiel

Regarding deinterlacing issue: I've uploaded a sample -> http://www.mediafire.com/?4cilzfa418ztey5
MediaInfo says it's progressive ("scan type") but it also has "scan order" property.

Though i guess for DXVA2 to get this working there would be no other way then to contact Nvidia and Intel and provide them such a sample so they can fix the behavior, i tried everything no go on HD2000 to get this smooth with DXVA2 with any Splitter->Decoder->Renderer combination. In Software Mode this issue fixes itself magically on the HD2000 either on EVR (normal) or as funny as it sounds with DirectVobsub on Evr Custom :P not sure though if that works also for Nvidia.

Hi!
After reading the first post its unclear to me, but does cuvid do all of the work on the GPU itself or does it use some separate decoder chip (which I remember dxva using.). Or some sort of combination?
Also does it have the sort of limitations that dxva does? Like that it wouldn't work at all with higher h264 ref frame numbers, or other video filters in the chain. (I see it works with all renderers so that's a plus)

Also what's the minimum recommended GPU? I'm thinking of replacing my 2600xt. I was thinking something like a gts450. (Not sure if its already the mentioned VP4 or hw or not)

Ok update i measured now the Power Consumption difference of Mpeg-2 Playback Intels Decoder (Hardware DXVA2) vs Lav Video (Software Multithreading) (on Core I5-2400)
and at least for Mpeg-2 i came to the conclusion that the Playback Problems that are mostly caused due to Hardware decoding aren't worth the hassle with @ best 1W save Sandy Bridge is very efficient here on the cpu part (nothing to cheer about obviously comparing to a real SOC neither the Intel Decoder result)

so 1080p with full 60 fps Deinterlacing takes approx 13W (idle 5W + decoding 8W (includes Parser,Aero, Audio (Lav Audio) and Renderer (EVR Custom) overhead)) on Sandy Bridge and Intels Decoder (tested via Microsoft-DTV-Decoder and Intels own Mpeg-2 Decoder both are mostly identical when it comes to DXVA2, still trying to find out how to get software mode working for both forcing renderer change is no good solution for constant measuring results) doesn't do much better with DXVA2 12W (7W) :/

It uses the same decoding unit as DXVA, but the GPU itself for deinterlacing IIRC.

It doesn't rely on a DXVA compatible renderer and it works fine with up to 16 ref frames. (But 16 ref frames also work fine on DXVA - at least on Vista/7, for pretty much every Nvidia Card and all ATI cards HD4xxx and newer)

Jep the difference is roughly 1 Watt and without Audio overhead and with default EVR (0.5W-1W still optimizing measuring) we are @ 5W (Intel Decoder) and 6W (Lav Video) (though if you calculate all the issues with DXVA2 into that with different renderer special adoption of Splitter ect i find this 1W very acceptable

MPEG-2 is a rather trivial format, compare H264 instead.

OK. Thanks for the enlightenment. I never thought that the ref frame limit might be video card specific...

Out of interest and given there is nothing in the tracker, is LAV CUVID "done", "stable" and feature complete (eg V1.0)?

Hi crunch. I made tests on 3840*1080 SBS file.

Here is my HW:

intel 540 on H55 (Clarkdale)
2*2GB RAM (1600 Mhz)
Geforce GTX 550 Ti

SW:

Seven 32 Pro, SP1 Build 7601
nVidia drivers 280.19

And here are my test results:

Splitters:

Haali,
Gabest,
LAV

Video decoders:

ffdshow video dxva,
lav CUVID

Renderer:

EVR Custom.

Avarage CPU usage is around 20%.




With same splitters and video decoders if i use MadVR as renderer, CPU usage climbs to 40% as expected since Madshi says:
