How To Use A Green Screen

 Green Screen backgrounds:

Here is a 90-second video showing how I can change backgrounds!

This setup didn't cost much.

I purchased the green background from Amazon for $15 ~ shipping was free because I subscribe to Amazon Prime. (Amazon.com/gp/product/B07L8Y8LJ2)

I had previously built a frame from PVC pipe, but eventually I simply stapled the cloth to the wall behind me. I used a common paper stapler because it makes really thin/small holes in the wall, and I attached it high on the wall. Paint will easily cover the dozen or so pinholes.

I used Zoom to record the video because the background substitution is built in.

I used my webcam and external microphone. You can tell I didn't take the time to write a script...
