Film grain

[spoRv]

Can I use a grain plate with a resolution of 2400x1350 (16:9) on a 1440x1080 (4:3) clip?

Of course, just crop out the unused parts.

Sorry for the insistence, Im not that great at making scripts, is this the correct way of cropping the unused parts?

Code:

GrainPlate(crop (0, 0, 1440, 1080), strength=0.15)

Yep, or just

Code:

GrainPlate(0.15).crop(0,0,1440,1080)

Remember, the grain is different on each layer of film, so it makes sense to apply grain on a per channel basis.

poita, please elaborate this, I'm ready to learn anything new about grain!

If I am not wrong (correct me if I am): On analog image procedure each color layer is produced with different chemicals... Also each of the base colors has its own layer. So each color layer ha it's own process, and thus it is common that the analog grain differs for each layer. I think that's why analog grain and simply digital added grain seem to be so different. Like in analog one dot of grain is only in the red color area, and thus has a different optical effect, because the other two layers have the normal colors in that area. While digital added grain on the complete image had an impact to all color channels...

Am I the only one who's not fond at all of grain added in post? The few examples I've seen so far have never been convincing but rather distracting.

It depends. Adding grain back to a film element which has been 'degrained' by noise reduction, filtering or heavy compression can be worthwhile if done appropriately. What I don't like is when grain is applied to digital video.
Colour me intrigued about per-channel grain, does the grain structure vary for the different emulsion layers?

Same here, i would love to know more about the applying grain on a per channel basis. Whats the best way of going about this?

I think it's safe to say that everyone has their own preferrence and that's okay. You are probably not alone in that camp, but among some of us here, you may indeed be part of the minority. I am also of the opinion that if it's going to be done it needs to be done with care. If it's done sloppily, it's damaging, and a waste. I believe most here that use or consider the use of grain plates, do their best to be very cautious, when doing so.

In the end, we ALL want a quality experience, one way or the other.
