LAV Filters - DirectShow Media Splitter and Decoders

[sneaker_ger]

It's probably a different output format than your other videos (10 bit 4:2:2?) and your renderer/GPU driver/OS messes up. Try madvr. (Or set LAV to only output RGB/4:4:4. I assume it has a better conversion.) It's a common artifact of low quality chroma upsampling.

[nevcairiel]

That certainly sounds like a possibility. 4:2:2 -> RGB upsampling appears to be of weird quality on some GPUs, so using madVR or LAVs upsampling (which might not be very fast on high resolutions, though, maybe I should make an AVX variant of it) could help.

Yes, prores is (8 bit) 4:2:2 and avchd is 8 bit 4:2:0
I'm using Win10 GTX960 EVR-CR

LAVs upsampling = set LAV to only output RGB/4:4:4 ?

[sneaker_ger]

Correct.

Thanks.

Or at least disable 4:2:2 modes, that'll force 4:2:2 to 4:4:4/RGB but keep 4:2:0 as-is.

Yea, I actually did that and now it's much better

I'll test with Intel HD4600 too, not sure what to blame

Running a decades-old OS which has stopped getting security updates long ago, and therefore constitutes a significant threat for yourself and others, is not a "matter of course". If anything, nev would be making the world a better place by disabling XP support, as it would encourage people like you to move to a more secure OS.

A more secure OS like Win10 for example?
That's a good joke...
(You do not read any security news, do you? "Security" and "Microsoft", these two terms are mutually exclusive.)

[e-t172]

Okay, I'll bite. You do realize that both OSes we are talking about were developed by the same company, right?

In addition, can you point me to at least one article from a serious website that claims that Windows XP is even comparable to Windows 10 in terms of security?

Let me suggest an experiment you could try: gather a list of the most reputed security specialists in the field (people like Bruce Schneider, Tavis Ormandy, Troy Hunt, and others) and tell them with a straight face that it's a "joke" that Win10 is more secure than WinXP. I would be curious to see how many facepalms you get.

I could go on and list all the security features that Win10 has that are not present in WinXP (UAC, Secure Boot, ASLR, BitLocker, TPM support, full DEP, service hardening, driver signing, etc.), but I have better things to do with my time. Come back when you have actual data proving that Win10 has more security vulnerabilities than WinXP (or even the same order of magnitude), then we'll talk. I would also be curious to see you explain how an OS that is not getting security updates anymore could possibly be more secure than one that is being actively patched today, because that just defies basic logic to me.

My 2 cents regarding XP and LAV: I upgraded my HTPC (Core 2 Duo/2 GB RAM, so not a high end setup) directly from XP to Windows 10, and it is massively faster and smoother at absolutely everything, all while only consuming a few hundreds more MBs of RAM.
On my newer desktop PC, it's snappier than Windows 7 too.
Modern OSes give you all kinds of advantages when it comes to media playback, there just isn't any incentive for developers to keep supporting XP, it's a waste of time for everybody, sorry VictorLS.

That's offtop here but WinXP (namely embedded version) must be supported until 2020. Updates for WinXP Embedded are good for ordinary WinXP. There are good offline updatepacks for WinXP - I have limited mobile internet only and WinXP not download any byte I don't want, Win7x64 downloads few kilobytes, but Win10 seems can't leave without Internet and when I connect it begins neverending download and upload despite of turned off Windows Updates and others. There is even AntiWannaCry in KB4012598 (ms17-010) for WinXP because necessary for many old programs Windows 2003 Server is almost WinXP )
Besides, as in Win98 time when all virus writers had been written viruses for WinXP I used Win98 until 2006 and hadn't any virus. I came from Win98 to WinXP exlusively due to DirectX (DXVA). Now history repeats with H265, but thanks nVIDIA for CUVID (and LAV Video Decoder for support) - I don't need DXVA (not supported in any drivers for any videocard for H265 in WinXP) anymore.

Not for - I wrote my experiments with Win10 in this thread before and that's true - Win10x64 is fast on my PC too but boot from second time (after Power on my PC first boot hangs up) and check my HDDs for a long time after and not working my radioremote and Internet consumption and HDD using (head positioning all time) in any Windows after WindowsXP and many other small things )

Windows 7 is far better than XP. I may use XP on old atom netbooks...

Since the conversation headed this way... I found 8/8.1 to be the best compromise, for now. It doesn't have all the crap of 10 (with sh*tty older hardware support), and is more efficient than 7.

But there's a problem, de-interlacing doesn't work in RGB32 mode at all

[huhn]

you could output 4:2:0 this can still be deinterlanced if the source was 4:2:2 but it is generally not a good idea to subsample even more. on the other side 99% of all sources are 4:2:0 anyway.

can EVR-CP/madVR not handle this?

Prores videos are mostly 4:2:2. How to output 4:2:2 as 4:2:0?
EVR-CP or plain EVR, same issue Haven't tried madVR yet.

Well, I tested Intel HD4600 and it has no issue at all, blaming Nvidia for outputting 4:2:2 badly xD

http://screenshotcomparison.com/comparison/214147

Interesting that Intel can de-interlace in RGB32 mode but Nvidia
I can upload a short sample if you're interested in

Now another topic about Inverse Telecine/IVTC pulldown, Nvidia GTX960 vs Intel HD4600



http://screenshotcomparison.com/comparison/214157
http://screenshotcomparison.com/comparison/214159

Intel has very bad IVTC, sometimes works and sometimes not at all

[huhn]

it is technically not possible to deinterlance a 4:2:0 source that is transformed to RGB the image is scaled vertical so it can't be deinterlanced anymore. (well there is a very a technically way to do that but... complicated and unnecessary)

so RGB deinterlancing support is just bad.

if EVR-CP can handle 4:2:2 correct you should report this to MPC-HC/BE.
EVR normal has nothing to do with that.

you can force 4:2:0 by disabling everything that is not 4:2:0
