Zen Films has a quick tutorial on using the DSLR noise reduction program Neat Image to remove grain and artifacting from video clips.

“…first output a clip from After Effects as a sequence of TIF images. Then, in Neat Image (NI) I load in a test frame…and practice getting a good output image using various noise filter settings…Once I’m satisfied, I save the noise profile and filter setting. Now the batch processing can begin…”

Great use of a non-video tool!
