Film grain
#51
I assume it's meant to be used on Log colourspaces?

Anything you want, works with davinci, fcpx, Adobe, everything.

Film Convert Pro really is amazing. I mentioned this in another thread as well, but thought I'd post it here too so that more eyes might see it. I work in vfx and we use it a ton. As Stamper already mentioned there are a lot of different options and it applies grain to the plate in the same way real grain would manifest on film.

Can't recommend it enough. I've used it in both After Effects and Nuke, but believe it also works in Resolve too. Could be wrong on that though.

Thinking of adding grain to the 35th Ann AAWIL using filmconvert in Premiere, does anyone know what the best settings would be for this film. Can't seem to find much info on filmstock etc outside of technicolor and what cameras were used to film it.

So since the blue channel has the most grain, how would one go about utilizing noise reduction on only the blue channel in avisynth? And if the source video is YUV, is there a way to do it without converting to RGB (since it will eventually be encoded with 4:2:0 YUV, so I'd like to avoid excessive color space conversions if possible).

You could just use normal noise reduction and then combine the blue channel from the result with the other channels from a milder denoise. But no, it won't be possible without a conversion to RGB and back, for obvious reasons. But you could use AviSynth+ and do the whole thing in 16 bit, to minimize loss.

I apologize for the bump, but I have a graining method that could be useful if anyone wants to try it. It involves using the conversion functionthrough VLC (i'm on 2.-something, but any newer version should work) and applying the grain filter (with settings being Variance: 10, Minimal period: 7, and Maximum: 64) to convert the file to an MP4 in 1080p and original frame rate 2 times, then downscaling to high bitrate 720p in VidCoder (otherwise you will get severe macroblocking from Sony Vegas no matter what settings you render with) and some finessing to 1080p in Vegas. This can works well for SR upconverted SD content that's been denoised as well as DNR heavy BD masters all depending on the source that is.

Here's some screengrabs for SD upscaled distributor logos done with this method:

I know this one may sound silly being the UHD of Predator resolves everything wrong with the Ultimate Hunter Edition, but I decided upon a regrain of it's Fox logo just to demonstrate how this method could work well on DNR'd HD sources.

Oddly enough, now it looks more like the 2008 BD despite the compression, and yet I heard the 2008 BD and UHE BD were a 4k IP scan but with degraining on the latter.

How do you apply the grain filter and make a conversion with it?

Depends on the grain filter you have I suppose. Although the general consensus usually with grain filters, or at least the ones I've seen, is that you simply overlay the grain on-top in whatever program you use.
