I decided to use Constance Wu’s face because of her role in the comedy Fresh Off The Boat, as well as the new movie Crazy Rich Asians.
Somehow I keep having difficulty making the screens appear. The numbers input does not run either.
You can see the black screens above. I’ve tried deleting the black screens and copy pasting new ones from working video boxes yet it still doesn’t work.
I turned on another computer to try. I decided to use back Brad Pitt’s face to do all testing first before carrying on,The screens all appear now (aka no black screens), however, the Brad Pitt image refuses to appear over my face under the bottom middle as well as the bottom right string of codes.
Frustrated, I airdropped everything onto a third computer to try. It didn’t work either. The face refuses to appear.
The second and third computers that I worked on.
I played around with the different modes of the alpha blend. I concluded that by changing it, it would not affect why my Brad Pitt face wasn’t plastering over mine in real time, rather it sort of changed the effects. I double checked that I’ve banged everything and still no luck. Also, the “s zzz” and “r zzz” does nothing, probably for printing purposes.
6.5 hours later, and hogging multiple computers, I conclude that I really don’t know why. I’ve consulted Mark, Margaret and Tisya who were kind enough to lend their time to try helping me solve the issue, despite that all was in vain.
2 days later, I’m trying it again. 
It works now!
So now I just had a little fun playing around with the jit.fastblur functions/values.
It kinda looks like a Chinese opera mask now, it seems to map the major similar facial areas of the image.
I doubled the ripple value from the previous image and it turns the image into this more intricate pixel areas of sorts.
Here I made the center value higher, it seems like the center makes the image more blur. I’m not too sure though.
