Pulling a hi-con matte from live action?

[BruceM]

I have a 4 second live action clip of ripple reflections on water that I'm considering rotoscoping, but would love another solution.
Is there a way to take this live action clip into TVPaint and pull difference mattes of the frames, so that I end up with a hi-con matte of the ripples?

Can TVPaint do this sort of thing?

Play around with colour adjustment and see what you get.

FX>Color>Curves set Mode to HSLO...

Adust the Saturation Curve to 0.
Adjust the Luminosity Curve as desired.

Thanks Svengali and Slowtiger!
I'll give these a try.

Svengali, the process you laid out worked like a charm.
Thank you!

Oh, yes, that works well. This is what I came up with following Svengali's instructions -



(added highlight "glints" on the water surface by duplicating the high-con water ripple layer and the applying Toon Shading FX set to "shading only/no border" with color white , then added a bit of Gaussian blur)

That looks great D.T.!
I've been looking for footage of water ripples and came up with something that doesn't look as good as yours.
Could I possibly use yours? Or could you steer me to where I can find it?

I used this:

Amazing! It looks like a totally different chunk of footage.

Thanks for this D.T.!
