Asking for a quick tip on this technique

[tomigoi]

Hi all. First time posting here.

I'm not sure what I'm trying to learn has a name. It has black background, and on the foreground there are a numbers of columns/pillars representing the window look.

Example : https://www.youtube.com/watch?v=i4gJvcwlT28

Usually the freedom of this is you can edit the content of the what's inside of the rectangle panels.

Here's one of the best example using this style.

Eventually I hope to find a tutorial showing how to do this. I'm a beginner.

Thanks a lot everyone.

It's called an "overlay". The foreground pillar layer is placed "on top" of the background. The slots are "transparent", so the bottom background layer (the "rectangular panels") show through . In that example, there is a 3rd layer on top of the pillars, because the black pillars are partially covered

Usually this is done in a video editor (there are many free ones like shotcut, kdenlive)

Because the pillar layer is static (it' s not animated) , you can use a still image such as a PNG with alpha channel. The alpha channel is required for the transparency. You can make this in an image edtior such as gimp, photoshop
