Re: nVidia NGX investigation
Hmm, I'm curious to know what materials you are working with that are gray-scale.
Re: nVidia NGX investigation
My materials are 4:2:0, but I only want to touch Y component. Colors are fine in 99% cases.
In general I want to undo cheap upscaling method on Y plane, re-upscale with better option, resize to 1080p and add colors back.

Gotcha, thanks.
Re: nVidia NGX investigation
It turns out that the ISR (Image Super Resolution) invocation is quite slow and will likely not be suitable for video at about 2-3 seconds per frame. So we have to fall back to the VSR (Video Super Resolution) functionality. I had been underwhelmed by it but that could be due to the subsequent X.264 encoding that is performed in the nVidia sample application. I will determine whether that is the case, and if so, then a filter could be a possibility.

Hi Rocky ![Smile :)](./images/smilies/icon_e_smile.gif)
Just wondering, did you ever find out what you mentioned regarding the quality of VSR? Is VSR inherently just not that great or was it due to the encoding?

Sorry, got sidetracked by bugs and stuff. Will try to come back to this. Putting it on my to-do list.
Hope you like your new avatar. Blame admin for that.

Can't remember offhand. I'll try to come back to this.

I wonder if they (nvivia) have done anything to make it better since back then ?
Or was it one of those "look at this" marketing features![Smile :)](./images/smilies/icon_e_smile.gif)

Thank you.
I wasn't altogether enamoured with it's stated description/limitations/performance so I guess I'll pass on the technology.

Have you tried it? Is it any good?
