Bob Ross intro recreation

[julppa]

Hi!

I have to recreate the Bob Ross Joy of Painting intro in my school project, and I have no idea how to tackle this problem.

How could I recreate the chroma key masking effect in the intro? I mean how the painting gets revealed under the titanium hwite canvas.

I get that it's been shot as a green screen and chroma keying has been applied to it. But after that it's a mystery.

If someone wiser could let me in on these secrets, I would greatly appreciate it.

Mask directly onto the video that is to appear sequentially, from each brush stroke. Use a separate mask for each stroke. During the shooting, place guides for the talent to stroke over - this is to ensure all parts within the 'appearance area' is covered.

Much easier/sompler solution is using the paint tool & then apply it as animated track matte

Thank you!

I'm doubtful you'll be able to animate the size of the brush as it's animated. IOW, you'll end up with a stroke which is fixed in width - this may not look sufficiently organic for this effect. Agreed that the Paint tool is more efficient but it's not going to look as effective as a mask.
