grungy, grainy video effect

I wanted to degrade a video to black and white and give it a grainy effect. Here's what I started with:


I then used the following settings to extract the color from the image:


The image then looked like this:


I then applied a histogram effect, tweaking the red/blue/green channels only allowing the higher frequencies:



To give the image a grainy look:


However, the grains looked too sharp, so I applied a blur using a pixel width of 8:


To this result:


Here's a test video (4.7MB):

Boy, does that blur effect take forever in Cinelerra. And my box isn't a slouch: P4, 3.2Ghz, 2GB of 400DDR. For this short, four second video, it took 4.5 minutes to apply the blur effect on the title at DVD resolution using YUV4MPEG & FFMPEG. Ridiculous. Here it is though:

Baby steps, I tell myself.
