This is what I am thinking. Please correct any error i have in my logic.
I have two daggers. one is regular, the other has been clipped halfway through.
Its dull and rounded so no danger of stabbing.
I want to film myself stabbing myself with the clipped knife and then add the shaft of the blade to make it look as if I am stabbing myself.
I need 2 things.
1) the name of the program needed to buy to make those happen. (I think i have exceeded the limits of my VLS on this one)
2) a link to a tutorial that explains how to do it

If foxhole offers asn application that will allow me to do this even better!


Thank you all for all your help in advance.

You should be able to do this in VisionLab. But, really, as with all VFX shots, it depends on the specifics of the shot. The specific angle you're shooting this, how long the blade is on screen, the lighting setup...these kind of things could completely change the approach.

Personally I'd shoot with the bladeless knife, 'stabbing' yourself, then shoot a plate of the bladed knife on the same set and with the same lighting setup. You probably won't need to actually move the knife, as you'll animate it in the comp.

Then mask out the blade and comp it onto the bladeless knife. As you shot it in the same setup it should match up nicely. A bit of animation to match the movement of the bladeless handle and it ought to look pretty convincing.

As I mentioned, though, it all depends on how you're planning to shoot this.

Well, if this is a clone we're talking about, you could just film it as two seperate shots, then mask out the knife as it goes into the "clone's" body.

I'm not sure why this.JUST occured to me. Get a sideshot.of you (or whoevers being cloned) pretending to get stabbed,.then move that person to where the stabbed is, and.have them pretend to stab someone. Do this all on a greenscreen, then in editing, put the shot of the stabber on the bottom,.and the knife should.go right "into" the other person. I'm typing from my phone, so sorry for errors. The first time I said stabbed I meant stabber.

I know it's not very high tech, but I'd plan on a stabbing close up and wrap the shirt or whatever gets stabbed around a thick pillow and a water bottle filled with fake blood.
Then a cutaway back to a wide shot of the stabbing

But I like old school stuff. wink

So...I don't have to buy a separate application?
I can do it with Vision Lab?
can i take a picture of the blade on a black background, remove the black in photoshop, then upload the png without the background onto VLS and then correct the size?
How do i hide the blade as it punctures into the skin?
i would need to make it disappear.

Ok.

1: get a sideshot of your person pretending to get.stabbed on a greenscreen.

2: get a.sideshot of.the stabber pretending to stab someone on the greenscreen in the spot that they should be in (opposition the person getting stabbed)

3: now, in edit mode, key out the green, and place the "stabber" layer on the bottom.

4: move as.needed, (to the left or right) and the knife should.look like its going in the other person perfectly.


Hope this helps. If I was unclear, please let me know.

Glad I could help. Just a tip: your greenscreen can be any material. Or so people on my thread about that tell me...


Also, who is that in your picture thingy? I swear she looks just like Jessica Rabbit...
