HEY,
In my new movie I need MY head to be chopped off ( lightsaber).
I have a idea how to do it.
Take a green screen shot of the actor, then have him put a green bag over his head. then take green clothes put them on the actor. then take the bag off his head, and have him fall with with the green clothes on.
put all together on the computer and youre done.
I liked when the cyborg got chopped in half in shougun showdown, cool
how did you do it mechaforce?

U might wanna put some makeup around the bottom of the neck, so it dosnt look like you just painted his head out, but it was actually chopped off.

You just gave me a great idea, ggbros biggrin For my recent decapitation fx test, I covered the actor's head with green cloth, which is essentially what you suggested as step one.

My step two was somewhat different, however. I used Photoshop to extract the actor's head from a still image and composited it onto the footage captured in step one. As expected, the outcome wasn't too realistic 'cos the actor's body was jigglin' and shakin' whereas the head remained rock steady and expressionless...

What completely slipped my mind was that I could've filmed the actor falling over without the cloth covering her head, and then painted (e.g. using the vector paint tool in After Effects) her body green. By compositing both shots, I would've gotten a much more realistic outcome.

Thanks for the tip! biggrin

thanks I know my post was a bit messed up!
But this is what I meant.

1. Film your actor against a green screen. Then stop.
2. Get your actor to put on a suit that is pure green. then film your actor fall.
3. Put a skin tight green bag over your actors head, then film your actor fall.
4. Take it onto your pc/mac. Ffirst take your actors full body green screen shot and key it onto your normal footage ( a lightsaber slash, a sword slash).
5. Just as the lightsaber slices through your actor cut the full body shot.
6. take the head green screen shot and the body and put them together. over your normal footage where the full body used to be.
7. make the head footage fall to the ground just before the body.

Id really wonderhow that looks like... I think the handmask method works better and is faster... But you may prove me wrong... :)

Frame by Frame work as explained in our tutorials... If you work exactly you´ll be faster than with greenscreen.
Besides I think to light a HEAD correctly (meaning that the green or blue is even) should be almost impossible for an amateur without a studio and professional software.

But as I said, you can always proove me wrong... :)

Here's how I did a shot like this in AE.

Film your actore in front of a greenscreen. Marking a line on the actor with make-up for the wound.

Shoot your background plate.

Compositing the immages together, you do three layers. the background plate, and two copies of the keyed-out actor plate. On the first actor plate, matte out the head, along the line you drew. On the second plate, matte out the body. Change the center axis point of the layer to the center of the head.

This way, you can set a motion path for the head to fall off and spin a bit, but still be live video- not a still.

My best results for this were done on a shot showing the decapitation from behind the victim. My background plate actually had my hero swinging his sword at a bag of blood hanging in the air. I then added my villian, shot on greenscreen, to the frame. I had him jerk his head to the side at the right moemnt, and with the spraying blood, and just a touch of spin, tt all came together rather well.

No that was a handmask! an 8-point garbage mask, to be exact!

With some painted lightning!

I like that very much! biggrin

I see your point of the static head but you've got the movement of the head as it flies off very nicely!

Did you have a very bendy sword by the way? razz

I've done a headless shot (without the decap action) in Mug Wars - http://www.cjproductions.co.uk/html/videofx.html

I'd like to try and do some more decaps now that i've been enthused!

Ah, very astute, Craig biggrin It actually isn't a very bendy sword; in fact, it's quite the opposite. The sword I used is the Marto Templars Sword, which is built very sturdily.

But the 'blade' that you see in the movie clip is actually a 'fanning blade' plug-in that I made specifically for this fx test. The actual blade disappeared into the ether after I keyed out the greenscreen lol

P/s: I didn't submit the 'fanning blade' plug-in because I felt it looked a little too rough, or as you pointed out, too bendy biggrin

Glad you liked it! Here's to more decaps in the near future!

Perhaps if you start the left side of the blade as the cutting edge and have the 'fan' trailing it as opposed to the blade being in the centre of the 'fan' as it currently is may make it look less wobbly/bendy and more like a fast motion blade.

Also I notice that the 'fan' actually bends outwards at the edges unlike the standard 'fanning lightsword' plugin whos edges are straight out. I've not analysed any sword 'fans' to draw a conclusion - but I know how ILM do Lightsabres! razz

Just a suggestion.

Look forward to many more decaps!

Upon reflection, the 'bendy' effect is actually an optical illusion. My plug-in was created from a photo of my sword's blade (taken head-on, so it's pretty straight), which I duplicated four times (ending up with a total of five blades). I then arranged them like outstretched fingers, and finished the image off with the application of radial blur.

I think you're right though: I should have emphasized the blade at one end, whilst blurring the others into a mist-like state biggrin

Sorry if I'm incoherent: it's 6.47am and I haven't had any sleep... I think I'm babbling...

The link's on the previous page. I couldn't post it in the AlamDV2 cinema because I don't think iTools supports direct linking to movie files, which is a requirement smile

In Quickening I had the decapitation take place just off the top of the screen. I thought it would be more dramatic. When the headless body fell, I removed the head by erasing it frame by frame in a multi-layered Photoshop file (I could have used a Filmstrip as well). Pretty time consuming, but I liked the results.

I originally planned on having the head fall to the ground a moment or two after the body. I opted to leave it out, but I did shoot the necessary footage.

In short, I sat down in front of the camera in the same lighting conditions as the headless body. I filmed myself as I slowly tilted my head back as if it were spinning end over end. After masking just the head in Photoshop and removing some of the frames (to speed up the rotation), I was going apply a motion blur to each frame and create an alpha channel for each frame. In Premiere 6, I was going to import the modified frames and animate the head moving from the top of the frame to the bottom of the frame as if falling. Of course, I can only guess if it would have worked...! unsure

Get the unfortunate actor, film all of their scenes save the head removal for last. Lay down a big plastic sheet and get a big blade. Say "action" as normal at the start of the take, say "Cut" half way through. Whoosh splat. After the take say "cut" again. Throw them in a ravine somewhere and there you go. Although if you have to do a retake, or reshoot any scenes. you're buggered. Actually that's not very helpful really. I'd use some kind of cunning prosthetic head, film from a long shot. Or you don't have to even see it happen at all The less you see is more you get. It's the same principal as the blood splatting on window shot as used in every film involving someone getting shot in a car. Just the shot of the head removal device, swinging forward, a brief long shot. Some blood splatting somewhere. And somehow have the person falling on the floor. So you can't see it clearly but you know he's missing one vital body part. Just remember to bring a mop.
