I would like to create a single colour background with Alpha channel, with wavy contours. I found a similar background in Techsmith assets. Is it possible to create such a background in Camtasia 2020? The related asset link is below.
Thanks in advance for the support.

What version of Camtasia are you using?

Aside from the link you pointed at, do you have any other examples?

Sorry, but the description is confusing as all get out. You want a single color? And that implies just a solid colored background.

But you then go on to say it should have alpha channel? So are you saying that you want this single colored background to be partially transparent? If it's the background, what would be revealed if it actually were partially transparent? Whatever the video appears in front of? 

Lastly, you mention something about "wavy contours". If your background is a single color, I'm not sure how it might provide wavy contours. Because that seems to suggest you need multiple colors involved. Otherwise, how would you distinguish the wavy contours? Unless, somehow you mean that you want many shades of that single color.

Is this what your shooting for?

If you can find a wavy video without a white or black wavy band. You can change all bands to the same color tone.

Given time to mull it over.
I turned down the brightness of the lower track a bit. That allowed me to colorize the white band.
How good it looks???
But clearly, experimentation will offer different results.

Dear Joe,
thank you very much for the detailed explanation of your solution.
This is not what I was looking for, but it gave me insight and I can use this method in other videos.
The example I shared below explains my question much better I guess. From your explanation above , it seems to me that it is not possible to create such an object
in Camtasia.

Well, thats quite different from the video you referenced indeed.
You could probably animate/morph shapes in Camtasia to create a simular effect.
It might not be as fluid, but I think its doable.

I thought converting the wave video to one color + alpha was a odd request.

I've see oddities turned into impressive graphics.

There was a you tube channel where someone did mystery FX work.
You had no Idea what was being created before you're eyes.
The video was played back in high speed.
As the video came to a close. You could be blown away by the end result.

Glad the video inspired you.

You just need the right piece of footage. I created some ripple edge half screen backdrops yesterday, then turned them into a Library Assets with a Quick Property that allows you to quickly change the color of the half screen. The other half is transparent and will reveal whatever is below it. Enjoy!
