Here's an example how to render a picture layer perspective correct on a background picture.

Camera tracking

To get the perspective correct you need to know a lot of props:
-FIELD OF VIEW camera layer
-POSITION camera layer
-ROTATION camera layer
-POSITION picture layer
-ROTATION picture layer
-SIZE picture layer

Smart camera tracking algorithms can help with this, but when the background does not move you can do it the low-tech way by using the Picture\FreeTransform effect. This allows you to move the 4 corners of the picture until it matches the background.

Making the picture transparent in a paint app helps when the border is irregular or should overlap the screen.

Colour map layer

The picture in this example does not use a JPG or PNG file, but links to a colour map layer.

To use a JPG or PNG: select the picture layer (layer 4), choose MEDIA > CHANGE TEXTURE... and click on the SELECT TEXTURE button of the 1st texture slot.

To clear the colour map layer: select the colour map layer (layer 5) and choose LAYER > ATTACH LAYER > DELETE ALL ATTACHED LAYERS.

To load a show into the colour map layer: select the colour map layer (layer 5) and press <Ctrl> M.

AI

The background picture has been made by ChatGPT. Please do not ask for the prompt. I don't remember the prompt and in case I did, it has no value because AI gives you another result every time you use the same prompt. Simply keep generating pictures until you get something useful.

If you want, you can upload this example picture to ChatGPT and ask it to render it in another style.
