I'm a newbie in Jitter and I wonder how to realize something similar to the attached example: x_hand.mp4

Here we have 2 still images: the hand-layer, and the x-ray-layer that is invisible until a moving strip-gradient-layer passes throuh the frame, that because the strip-gradient-layer (see y_hand.mp4) is the luma_matte of the x-ray-layer.

I'd need to realize the same thing in Jitter. Could you kindly suggest me a tutorial or something similar to understand how to proceed?

easiest way is with a simple jit.gl.pix patcher:

search the reference browser for "Video and Graphics Tutorial 10: Composing the Screen" for more info.

Thansk you so much Rob for your precious reply!

Unfortunally I can't find that tutorial on my Max7's browser...

Anyway, your patch is exactly what I was searching for.
