Hi,
Thanks to anyone who answers this... I would like to make scorch marks from a fire with Vision Lab and how would you make a Hole with rubble around it with Vision Lab. I Saw for Vision lab advertisment there is a ball of fire falling from the sky and hits the ground, leaves a hole there with fire coming out of it, so I'm looking to make these effects, how would I do this? Thanks Again!! Chad

If the video wasn't just for advertising of the fire-on-meteor effect, I think that the hole in the ground was done by a still Muzzle Flash effect.

For scorch marks, generally the best bet is just an image with an alpha channel, such as a png or tiff, which you can then composite onto the footage to add the scorch marks. You just need an image editor to paint up the original image, then drop it into your composite. If you paint the black scorch marks onto a white background, then the Multiply blend mode should composite them in nicely.

Go into an image creator/editor such as Gimp or paint. Create a dark object with some sort of feather, like I did with a white background, as Axeman suggested.

Next you should import this into Vlab. Open the image and place it on the timeline.

Place it on the timeline. Make it whatever length you want and change the composite mode to "multiply" once again as Axeman said.

I don't have VLab so I don't have the option to make it "multiply." However it should be found in the same place. Hope this helps! biggrin

What I tend to do for scorch marks is to create a mask in the area where the mask was going to be, feather the edges slightly till it looks right. Because there is no footage under your layer the black will show through, altering the opacity of the mask helps as well.

that works, but is there a way to set the duration of the mask? (i'm a noob) you know, so the scorch mark is only after the explosion?

There are two easy ways to handle that. First, if you slice the background clip on the frame where you want the mask to appear, you can apply it to only the second half, after the slice.

Second, you can position the mask on the first frame you want ti to appear, then step back one frame and drag it off the canvas, out of the shot. This will keyframe its position so it appears only at the point where you need it.
