Hello,
Figured this out today and I didn't see if posted in the tutorials or forums so I figured I would bring it up.

In many things recently I have seen video where all the footage was black and white except for one color (generally red). I figured out a fairly simple way to do this in chromanator.

1. Render out 2 copies of your footage in your main editor. One of them being black and white and the other being full color (if your colors are a bit dull you will want to tweak the brightness/contract and color balance until you get it a bit more vibrant.

2. In chromanator import both files to blank tracks with the color footage on top.

3. Use either the color differance key or the hue key to key out your desired color.

4. Turn on the invert matte option and tweak the black and white pointd and range if needed.

I have included example pictures below.

I also noticed if I used the box blur you could cause the color to kinda fade and wash out. (this is done slighlty on the example picture below)



thanks,
Vesicant

To save on disk space, you don't need to render out two copies of the same clip. Just load the original in, place it twice on the timeline and apply a desaturate filter to one of them.

Didn't even realize chromanator had one smile (only about halfway through the manual so far)

thanks

Nice. But you wouldnt be able to do that with say, Yellow? Unless you felt like masking... but thats another story.

Some of the new upcoming filters should hopefully make this technique even easier.
