Noisy grain in my project - Solved!

Hey everybody! I am a Houdini user learning TD and I have a strange problem. I am getting some sort of a black grain in my TD project. I think I have traced it down to the Bloom image filter. I suspect that I need to be clamping either my color or luma someplace. Do you agree? video

Looks like I was driving the gama control on the Bloom way too high.
