Part 2:) one example of using said footage to live action:

WARNING!! Gory, not for kids. And it may not be exactly what you’re looking for in your shot but it might give you a jumping off point.

That’s a great link. Thanks. I need the actor’s face to get smeared with blood, he’s getting hit, CU, about 5 times in a row, and his head snaps with each blow- no cuts on this- with each turn of his head- as he brings his face back to camera, that’s where I need the blood applied- blood from his nose, mouth etc. So it’s not really exploding- it’s smearing and dripping. And of course, his face is moving constantly in the fame. Any thoughts?
Thanks again!!

eee… I’ll have to defer to someone else on this. I mean, you could always motion track the person’s eyes or some other feature of the face and position the blood (offset to the nose or mouth) to match the movement of the head. But the smearing, dripping part is tough… at least in a way so as to not make it look so fake as to be distracting. Certainly there are ways to do a smearing and/or dripping effect such as:

But getting it to appear on a moving face and have it be convincing with the same lighting, etc. is tough.

If it works for the feel of the movie, you could also change the color of the footage as the character is getting hit to an oversaturated red and/or sharply wiggle the position of the movie in sync with each hit to somewhat hide the lack of blood but still have the violent feel. Not sure if this is clear. And of course, not sure if it’s in keeping with the feel of the movie. Just something that came to me.

Perhaps someone else has a better idea. Best of luck!

Eeeee indeed. I don’t think the guy in the movie can shoot again-so I’m in a tough spot. Thanks for the great help- and I’ll keep plugging away- please feel free to send me more ideas- I can use the help!
thanks again!

I just shot a film and I wanted to touch up the blood work via green screen. I’m using a hose attached to an air compressor and shooting it against a 9 x 15 green screen. I have several questions regarding the process. If there is an online tutorial regarding the very nature of this, please link me up instead of answering the following questions (except for the last one). If not, my questions are these:

How far should the camera be away from the green screen?
How far should the blood work be away from the green screen?
Is it okay to get the hose in frame?
Should the hose be the same color as the green screen?
How accurate should the framing of the special effects footage be to the framing of the original footage? What do you sacrifice if the scale of the blood work is adjusted in post?
To achieve a blood spray alla one created by a sword, what is the best way to cut holes in the hose. (how long? how wide? multiple in succession?)

Thank you so much for your help.
