Camera Shake & Film Grain - Razor Crest VFX Lecture 23

Adding a subtle camera shake and applying film grain to the make the shot look less clean.
These lectures were originally built for a college VFX class that I teach, taking students from beginner to intermediate level. Over the course of this 9-hour course, brush up on PBR surfacing with UDIMs, learn about lighting, AOVs, render layers, batch and sequence rendering, EXR compositing, and ACEScg with Maya, V-Ray, and After Effects.

I've never thought to add rotation to a wiggle expression for camera shake. Very interesting idea that

[@CGStirk]

Yep, and a little bit goes a long way.

this project is completly cg or combine video with 3d model?
as you mentioned, all cameras have grains, If we only render the 3D model in V-Ray during rendering (without video in the background), then in After Effects, with this "add grain effect", can we tell AE that the grain in the 3D model is exactly the same as the grain recorded in the video? if yes, could you please tell me how can i do that?
thanks alot.

It's completely cg. There is a Match Grain effect in After Effects, but it won't be exactly like the noise in the rendered frames. You should output clean frames from max, and then add noise in post. Use the denoiser to make rendering without noise more efficient.

thanks.
as you know in vray, we have Denoising render element And with that we can eliminate all the noise of the final rendering.
The point is that usually the videos that are taken with smartphone or cameras have alittle noise and grains, and our rendering is completely clean and without noise and grain.
Actually, I wanted to know if it is possible to add noise and grain to the clean render based on the video that has some noise and grain. can we do this with match grain tool in AE?
thanks alot.

The Match Grain effect just samples the source and tries to replicate it, but you'd have to test it to see if it does what you want. To get phone video compression quality directly within AE would require a plugin. Or, you could render out the final comp and reimport it to get that some poor compression quality from actual compression. Not an ideal solution, though.
