How We Use a Projector to Replace the Background in 4K

Today at Butler, we're showing you how we use a 4K Short Throw Projector to replace the background for our video shoots. Using a projector allows us to create interesting and dynamic backgrounds for our videos, without having to purchase expensive backdrops or build sets. We can project any image or video onto a wall or screen, giving our videos a professional look.

Thanks for sharing, I have a hack that you might be able to use to make this better. I have a projector I use at home, and I wanted to check out how it would look on a larger wall, So I went to Home depot and bought the largest painters drop cloth I could, 12 X 15 feet for 40 bucks and some command strip hooks to hang it up.
What I learned is that the painters drop cloth is transparent for the image being displayed so, if I do not have my shades down you can see the image very clearly on the reverse side of the painters drop cloth.
So if you found a cloth that works well and has the right amount of transparency you can project on the back instead of on the front, this might help with some of your lighting issues as the projector would be on the other side of whatever you want to film in front of the back drop. But this would also make it more flexible for you as well, because the projector would be completely out of your way, so you could mess more with your subjects position relative to the backdrop.
I found your video because I thought this might be how movies are going to start making movies, instead of having a green screen where you have nothing to react to, you can project anything you want on a transparent canvas which would be visible for the actors to respond to. But they are probably gonna keep doing primary filming before all the VFX probably.

It would work with a video? That was a really cool way to dinamize the background!

[@ButlerBranding]

Yep! We bought it specifically for video.

What is the white screen you used ?

[@ButlerBranding]

We used a pretty cheap one and it works great amzn.to/40ZSngW

The still look a bit washed out to be honest also in the first shot you could see some pixels, you could have project the images on darker cloth I think
