Can’t remove grain (After Effects CS3)
okay, I have a scene in quicktime (.mov) format and its raw digitized footage from a dv camcorder. I opened the file in After Effects CS3 and applied a Magic Bullet preset filter on it, and removed grain successfully. I was just doing this to see if I could do it alright.
But after I edited the video in Final Cut Pro I exported as a quicktime file and tried to import the final scene into After Effects to do the same thing, to remove the grain. But when I use the remove grain effect it does nothing.. I adjust all the settings and nothing changes. I was wondering if anyone knows why? Would love to know soon as possible :S
cheers

Hi Chris,
I had the same problem today and this is why and how I fixed. I hope this is not too late for you.
By default, the Remove Grain effect take noise samples from the first frame of the sequence; so if this first frame has no noise, the Remove Grain plugin seems to has no effect. In my case, the first clip of the secuence had a fade in from black, so my first frame was completely black, with no noise of course, and the Remove Grain did no adjusment.
To fix this, you need to change the “Source Frame” from the “Sampling” setting of the plugin, from “0” to any other frame that has a representative amount of noise in your sequence and that`s it. It is a simple thing but it took me a couple of hours to figure it out. I hope my experience can save some of you time, fellows, as many other threads had saved mine. -
you are a genius

Hi Ernesto,
I’ve had the same problem (Remove Grain just doesn’t seem to work) and was glad to find your advice. However, this doesn’t do it for me. I’ve been setting the source frame to every other frame of the clip and the plugin still doesn’t remove any noise.
Funnily enough it does work on a few other clips in my timeline, but there are no differences (e.g. opacity, file format, or additional effects) between these clips and the ones the Remove Grain doesn’t work on.
Have you got an idea?
Best, Phil
