Rotoscope masking issue
by Andries Dillen on May 23, 2009 at 11:42:25 pm

Hi all,

Im gonna start with showing what I've achieved succesfully so far and then I'll explain my problem.

As you can see I've made a rotoshape that covers the DJ and I've put scrolling text in it.

This I have done the following way. http://users.telenet.be/sickbrain/Afbeelding%202.png

Voorbereiding2_57 is the footage, groep 2 the rotoshape and SFileIn1 a psd with the text that makes a left to right move.

So far so good.

However, the next shot I have 2 DJ's at the same time. I've rotoshaped them both and put the 2 shapes in 2 different groups. I now want to put some yellow on blue text in one DJ and some blue on yellow text in the other DJ. They both are in the same shot and at some point they overlap so at some moment there is a forgroundDJ and a backgroundDJ.
I've uploaded a screenshot of how I've laid it out for now

Anyone who could provide me with some insight as I'm quite new to Shake. If you need more info just ask and I'll try to explain it a bit better.

Tnx in advance,

Andries

Use an Over node with video on BG, your colored txt on FG, and connect your rotoshape to the txt mask input. Repeat for the 2nd mask, or use multilayer node.

There are many other ways to do this, as it's real baby compositing.
You may find useful to read the Shake manual entirely, as it's really full of valuable stuff, and quite funny to read ;)
