Reduce Noise does not Work?

Check to see if your project was 8bit or 16/32bit. Sometimes I had issues with Remove Grain in 16 or 32 bit projects.

I know this post is old but for others chasing their tail with this:

By default the Remove Grain filter works from frame 1 of the movie. So if you have black at the start from a timeline export, chances are it will have no grain in it and the effect won’t do anything. Simply advance the source frame parameter from the Sampling section in the effects controls tab to the frame you’re looking to reduce noise in, then the effect should work fine.
