Flying People and Editing?

XTREEMMAK wrote on 1/7/2003, 2:06 PM
I dont have them done yet, but later I will be recording scenes of people and they'll be on wires. Problem is, I dont know how to set that up! I have a set stage were I want it to be seen, but I dont want the wire to be seen. How do I go about doing that? I know that the Chorma Keyer will not work, cause all I'll get is a big line through the picture. Any ideas?

Removing wires is usually done with chromakey and mattes, or with rotoscoping. If the cable is keyed, it usually works just fine. Keeping the cam locked down, you'll be able to insert matted background of what you have.

No,
but the scene has to be recorded in a live setting. I know Choroma Keyer wont work because there's nothing behind it. So what do I do? I understand the camera still part, but since it's live and live has an ever changing atmosphere, what do I do? Or am I apporching this the wrong way? Should I blue screen the wire screen and then add it to a live scene? Or is there another way to do it?

The easiest way is to shoot the flying against a chroma background with a locked camera shot. Rotoscope out the wire and then composite it with a locked background shot. That is the down and dirty way.

I have done many shots where wires and stuff had to be pulled out of a picture. You can do it against a live background with a moving camera, but you need folks with talent to do the clean up afterwards. Wires are generally small. Frame by frame you go back through it and lightly smudge the wire out. The key is that it has to be done very similar from frame to frame or it starts to look strange.

We have an artist down here, Amber Larkin, who is very good at that kind of stuff. On the last composite job she did for me (a nail being driven through a wrist with oozing blood) she added a slight camera shake after the fact to further camoflauge the effect. It was fabululous! She did a lot of wire removal and morphing work for Xena and a couple of other shows.

Have fun!

Are most movies shot with still camera's to edit out the wire action?

How difficult is it to do that smudge editing thing you told me about?

How would you do it in Vegas?

A movie camera is just a still camera that takes a lot of pictures in a row at a set speed. No, movies are shot with movie cameras and video cameras (except portions of the Matrix which was shot with 35mm still cameras).

It takes a lot of talent and is delicate work. I have done it on a 10 frame clip but nothing longer.

You can not do it within Vegas. It is done in a rotoscoping or a video paint program. You might be able to do it in Aura DV.
