Help with green screen and stock motion video

  • Updated 5 months ago
I am using the following iPhone motion graphic clip from the Asset library (https://library.techsmith.com/assets/asset/v/3557372). 

How can you use Camtasia to add a video to the green area of the motion image? Removing a color just shows the background.

Any help would be appreciated as I would like to add a video to the stock video.

You need to put a video on a track and then put the asset on a track above the video.

Color remove the asset green.
your video should be showing behind the asset.

Lock the asset track so you can
scale your video track to fit in the asset view.

You would need the video to twist and turn mapped to the I-phone.

Technically, you wouldn't actually need the green screen at all.A standard I-phone and the "Corner pin effect".
Animated through key frames is what you want.
You see as the phone twists aspect ratio/and or the perspective of the video changes. So all 4 corners of the video have to be adjusted independently of each other.
It's a painstaking process to do manually. But very difficult to with a tracker because phones most in stock footage like that don't have good tracking points.
Heres what a manually tracked I-phone looks like in Premier Pro.It twists in sideways. The long blue tracks represent the path of the phone.One frame at a time.


Camtasia cannot do this. It doesn't have corner pinning or anything even close to it. If you want to use a free program that has it.

It's called Quad Warp.

You could cut out the twisting part in the beginning. And place a video behind the phone with the green removed through remove a color.That would be much simpler.
But if you want the full animation with a twisting phone, you'll have to put in the work.

Joe, thank you for the detail. It is sad that Camtasia would put these type of stock assets in their site with the term "Easy to customize" when the truth is you can not use them in Camtasia nor is it "Easy"

Sean, your dig on Camtasia is inappropriate. As you learn more about video manipulation and editing you will discover that entire suites of software tools are necessary to do what might seem easy to you now. Blaming TechSmith because a third-party video clip does not match one of their video clips is like blaming Tesla when your car can't drive from California to Hawaii. As you practice and learn, you may discover easier ways to accomplish what you are after. 

Here are some other assets that might help accomplish what you want more easily, using the instructions in previous answers.
