mpc-hc, cleaning the video

[Bily]

Hi


How can I remove defects, various types of noise in excessive amounts, from a video in mpc-hc in real time to make it clean and crystal clear?



Thanks

Does anyone know if there are shaders or filters for this noise problem?

Thanks

Of course there are, but not a magic filter to solve all kind of noise and defects on the fly.

Put your sample.

How can I put my example image here?


Is there a website that has a lot of shader downloads?

Thanks

Upload sample video to google drive or similar and post link here.

Please share public


see if it worked now

remember I'm upscaling 1080p to 4K through MADvr

and no noise cancelling is connected

Broadly speaking, when you have a low quality source with artifacts, try a blurry scaler such as a soft bicubic. That's going to be the least destructive to the source, it works quite well on old SD content. For MPC-VR luma the softest one available is Mitchell-Netravali.

Any other post-processing you want to do has to be tuned to the source, ideally. In MPC-HC shaders you could use one of the Gaussian Blurs, maybe followed by one of the Sharpens.

In madVR you have more options. Pick soft scalers/doublers and work your way through the post-processing settings, comparing the effects as you go.

You're not going to make a bad video into 'clean and crystal clear' no matter what you do.

with old SD content

Do you suggest a set of mpc-hc shaders?

in pre or post?

even using madvr?

thanks

No need, you have very soft scalers available in madVR, moreso than the other stuff except for the actual gauss shaders, but they take a lot of detail away too so, no need.

Just use madVR, pick a SoftCubic for Luma, maybe try a LumaSharpen afterwards, 0.5 should give you something. SuperXBR on a soft setting like 50 or less could also work nicely if you want to do image doubling. In that case, you don't *also* have to have a very soft scaler, you can use something more neutral like Catmull or Mitchell.
