Motionless Blood Splatter

[Steve Roberts]

Tilts down! Tilts down! Pan is across, not down!

There.

Now. Make the blood spatter image by spraying red goop or whatever on a white wall. Shoot a still of that.

Then you need that image to stick to the wall. The right way would be to get a 3D tracker such as Syntheyes to track the room with the camera move, then export 3D camera data to AE so you can take the splatter, make it a 3D layer, and try to move it into the scene so it fits.

Now if you wanted it to spray at the wall and not just appear there … I might use Trapcode Particular to make a bunch of red dots shoot at the general wall area, while using a mask to reveal the shot blood on the wall. Or you could try using particular to make particles that stick to a 3D layer, standing in for the white wall.

No, AE’s tracker doesn’t do 3D. You might be able to use “corner pin” on a splatter image then just animate the position of the splatter so it goes up when the camera goes down.

Next time, tell the producer or DP to test the effect before shooting. You might find that doing it as a practical (on-set) effect is easier.

Anybody else?

Thanks for your advice…. Sorry, i should of said Tilt and not pan! gone 01.00 here in the uk!

For the Blood splatter i used Andrew Kramers Riot Gear splatter and inverted and coloured red. I have no problem splattering this effect against the wall, but i wish to hold it in one place as the camera Tilts?

Well, either you manually animate the spatter moving up in the frame, or you try to use (buy)Syntheyes to attempt to track the room features and create a 3D camera that moves the same way your camera did.

If you try to do it manually, as I wrote, you’ll need to Corner Pin so it distorts to fit the wall, then move it up in the frame.

how close is the shot to the actor? is it a close up or wide shot, because I just did a similar wide shot & simply used the tracker inside ae to keep the splat in place, which worked perfectly & only took 2 minutes.

If you can track a point on the wall close to where the splatter would be, yes, that would work. Otherwise you might get slipping due to parallax.
