OK folks this is for all you grain lovers. This is for After Effects but I'm sure it can be done in other programs too.
I came up with this because I really wanted lovely grain after looking at 1080p stills from BluRay releases. I just couldn't get good looking grain using plugins.
This is what I do:
1. Download the PNG grain file which was created by Petteri Sulonen for use in his helpful tutorial on black and white photography on his site:

Note: The actual link to the grain file is beneath the thumbnail on the bottom of the page.
EDIT: or buy one of a selection of grain files here:

2. You need 1080p crops of this large image to use as animated grain. I use the wiggler in After Effects
3. Import your lovely new grain PNG and place it at the top of the composition.
4. Go to Position and insert a keyframe on the first frame, and another one on the last frame.
5. Open the Wiggler palette
6. Click on Position in order to select the first and last keyframes
7. In the Wiggler>Dimensions>X
8. Frequency = [enter composition frame rate]
9. Magnitude = [(grain document width minus composition width) divided by 2] and click Apply
10. In the Wiggler>Dimensions>Y
11. Frequency = [enter composition frame rate]
12. Magnitude = [(grain document height minus composition height) divided by 2] and click Apply
13. You now have a different Position keyframe on every frame, spanning the area of the image at random.
14. Change the grain layer blending mode to Soft Light - beautiful grain!
15. If you want some flicker, just Wiggle the gamma of the grain layer - Levels (Individual Controls) effect > RGB > Gamma...... I recommend a frequency of half your frame rate and a magnitude of 0.1........if you need a more subtle flicker then do it on an Adjustment Layer and then reduce opacity.
This will give you the sexiest grain of all time. Just compare AE's Add Grain effect and you will see how dreadful it looks in comparison to genuine scanned grain.
One caveat: A lot of this loveliness is lost in compression to your export format, so do bear that in mind.
I've tried it outputting to DVD and even though the grain almost disappears there is a subliminal influence there, without a doubt, that adds to a film look.
I could upload an uncompressed 5 second clip of the grain but the file size will be around 800MB.
Let me know your thoughts on this folks!
PS: If you don't have AE, or a Wiggler type control, just set keyframes manually for each frame, moving the grain image each time, then loop a short sequence of it.
