Yes, just take the audio track from the VHS capture, and remux it into the 1080p one you have as another selectable audio track. What software you use to assemble the mkv will depend.. Handbrake is one you could consider using.

Also tried this and full of dropped frames making movie unwatchable.Software decoding also gives me dropped frames because cpu is old.I am forced to use D3D11 and things there are going smooth except the sometimes crash with a 4k movie where I still don't know why it happens.I've also sent a report to AMD this time when it crashed.

That's weird, you shouldn't get noticeably worse performance since you can use HW-decoding for both DXVA2 and D3D11. D3D11 also produced crashes for me, usually releated to long video pauses and resuming later - this was before MPC-HC introduced the feature to fully stop and re-start video after long pauses.

Dxva native plays just fine but as I read it's not recommended quality wise.Copy back yes,makes video unplayable.Maybe a driver problem?I don't remember having this problem in the past years with same settings.I am watching more 4k movies now though.

Yep,crash again.Madvr gives ''getting display mode failed'' message as I see.Googled a bit about that and one guy used DDU to fix it and the other one updated his drivers.I've done both and no success.

It seems like it was a driver problem and by installing an older adrenalin driver stopped the crashes.Thank you very much guys for trying to help.

NGU AA med with 4K movie was too taxing on this old 4GB RX 470.It crashes with latest drivers while with older driver from 2022 it doesn't.I've got a 50 inch TV set at ~1.53 meters.If I set chroma to jinc is the quality loss noticeable in my occasion?

try super xbr.
polaris can't handle ngu.
and something is very wrong when your device crashes and that's not madVR.

NGU AA med for chroma and NGU sharp med for luma was what I was using for years with this polaris card.After updating to a most recent 2023 adrenalin driver crashes begun with this message:

"AMD crash Defender has detected an issue with your display driver. To prevent a system crash or hang, the display driver is now operating in safe mode with reduced functionality. It is recommended that you save all work and close any open applications. A system restart is required to restore your graphics hardware acceleration."

Before that I was stable for years and the only thing I changed was to update gpu driver.

Here is my usage with NGU AA med for chroma.It's a 16:9 4K remux.Do you see something worrying?

So just do what the other guy did a few posts back and roll back your driver?

@Damien147 Don't go crazy with chroma upscaling. It only needs to be "good enough" in terms of colour, saturation, etc. Luma is where you will primarily notice differences between the algos.

If your memory is fine, maybe it's your power supply? Voltage rail issue?

Yes,that's what I thought too and rolled back yesterday.The driver optimisation for this 2016 GPU finished years ago I suppose.It's not like I am missing something.I am gonna check again when another driver comes out to see what happens but I am not in a hurry.

Yes,I've read in the past here guys mentioning that luma matters more than chroma but I didn't know exactly at what extend.I have my TV set for 40 degrees viewing angle.Is chroma observable in my case or not?I didn't know that.In normal viewing conditions I mean as I sit on my sofa and not by sticking your face to the screen to see a difference.

On an earlier post I said that I ran windows memory diagnostics for memory and for power supply I did this.Both results told me that things are working properly.I don't experience any other instability on my system beyond this crash that happens with newer adrenalin driver and 4k source.With newer driver if I lower chroma crash seems to stop but I try to avoid lowering settings if I don't have dropped frames.

NGU AA places the chroma slightly wrong and is slow just use super xbr.

even through reconstruct is looking good here it can go totally of the rails in other scene. super XBR is cheap and pretty much never fails.

My fave chroma is mitchell-netravali on my hardware (igp).. it's not demanding on resources, and the nice thing about it, in terms of luster, body and colour it seems to have a good balance.. some other chroma algos tend to look "flat" or emphasize certain colours too much, etc. Super-xbr is a good choice too if you have a dedicated graphics card.

Luma is more complicated.. there's such a thing as too sharp. Very much personal taste there.

Really?I thought NGU AA was the best thing if you could handle it.What sharpness you suggest with super xbr?Anti ringing filter ticked or not?
My aim is to have natural picture with best possible upscaling.

anti ringing on.
100 to 150.
150 is good for 1080p sources where another scaling is happening and at native resolution 100 is plenty.

I want to put a set and forget setting for everything.Does 150 have a negative impact at native resolution?
In general most of the movies I watch are full hd but when I have a choice I also watch 4k.
With what you are saying I am thinkin' anti ringing on and sharpness at 150 for everything but I don't know if 150 affects 4k in a negative way.Am I fine like that?


edit:I googled how to create a profile for chroma and found an article.Just copied some settings and succesfully created it with the settings you suggest.


huhn you've always been so helpful through the years and I really appreciate it.Thank you very much.



At last after 3 weeks a positive outcome was created.I guess I can use latest driver without a crash now that I lowered chroma.




Thank you all!!!

This conversation has made me think again what would really be the best setup for a soft (but not blurry) image, which I'm after as I very much dislike any amount of graininess. I've been using NGU AA with reduce ringing artifacts (and reduce dark halos), reduce compression artifacts at 7 medium (with chroma also) and soften edges at 3. Would it be better to use Jinc, as it only upscales without doubling? Or does it give overall worse image quality (and if NGU AA is problematic, then compare it to NGU Soft)? It has less sharpness, but also slightly more aliasing and ringing, and no amount of hide source artifacts. Then again, it wins clearly on "other artifacts", whatever they are. Are there also other things to consider (naturally my monitor is at zero sharpness and I'm also using Philips' noise reduction at maximum)?
