Bas Jan Ader Endimione Posted April 15, 2020 Share Posted April 15, 2020 Hi guys, I'm grading some anamorphic footage shot on BMPCC4K on 2.8K anamorphic mode (sensor cropped to 4:3). I was wondering, adding film grain in post, which aspect ratio should I apply to the grain... Link to comment Share on other sites More sharing options...

AJ Young Posted April 15, 2020 Share Posted April 15, 2020 (edited) Honestly, it's personal preference. I shot this on the Alexa Mini with Atlas lenses and added the grain after desqueezing: In theory, if you shot on film, then the grain would be stretched. But, does it have to be? Edited April 15, 2020 by AJ Young Hmm, it seems that the jpg compression is hiding the grain. I can send a .png to you via email if you'd like.

Premium Member David Mullen ASC Posted April 15, 2020 Premium Member Share Posted April 15, 2020 There's no law on the books requiring that the grain be squeezed if that's what you mean by "does it have to be". At the near subliminal level that most grain exists at, I think it's hard to tell whether it is squeezed or not. But if you're afraid that your post-added grain looks like post-added grain, then I suppose taking the extra step of squeezing it to match the optics isn't a bad idea.
