I have to do presentation for my visual effects class. I was goin to do it on gatoraid and how they make there commericals. Does anyone know how they make the sweat the color of gatoraid. thanks alot 🙂
it’s all roto. 😀
I actually did one of those. Yes pulling,keying,rotoing mattes then CC the F/G to whatever color you desire.
Although I think it might be by powerade, the one with the athletes shattering might be more interesting than the coloured sweat. Where do you have a visual effects class? Anyway, I think DD still has the breakdown for the shattering one on their website.

like digital domainI’ve worked on a few of these…it’s mostly old fashioned roto and paint work. Often a combination of these in the same shot.
The strategy depends on the kind of shot…if there’s a lot of movement in the shot (i.e., sweat flying off someone being hit in the face), paint mattes are generally easier. But if there’s not a great deal of movement, then tracked mattes are easier to keyframe and not as “wobbly” as hand painted ones.
For close up drinking shots, where there is udulation of sweat over the skin as the person is drinking, i like to use a single frame matte that is warped to match the skin’s motion.
For the actual color, a simple color correction using a matte doesn’t always work. Often I’ve had to use multiple layers to get it to look vibrant enough, with different blending modes for each. But then again, sometimes simply using the tint brush in paint with the color you want works fine.
Like anything, the key is good production (which we unfortunately don’t have a lot of control over..hah!) …having good sharp sweat droplets that look good when they’re color corrected. When you don’t have good footage, then you end up tracking real drops on skin, using particles for sprays, etc.
These sweat fx have been done now for almost a decade…so they often raise the bar by adding other effects in addition to the sweat, like a spot we recently did where the sweat causes grass to grow, then you’re looking at a whole other ballgame.
Hope that helps!
