How to make a screen replacement affect | Blender 4.2

This video shows how to make a screen replacement effect using Blender 4.2. You will learn how to make a screen replacement effect using footage in Blender. The final render was done in Blender.

Tracking

I will be using a video I downloaded from Pexels

I open the motion tracking workspace under the VFX menu

I open my footage and under the render properties, under color management, I change the film look to standard

I also set my scene frames to match my video

I select prefetch to load my video first so it will run faster and smoother when I do the tracking

For the match, I will use keyframe and I activate normalize

Under the tracking settings, I change the correlation to 0.9

On frame 1, I hold down the CTRL key and draw a rectangle over the four corners of the laptop screen

I use the A-key to select all four corners and track the markers forward

I scrub through the footage to make sure the track is good

I select all the trackers on the laptop screen and open the solve panel

I twirl open plane track and create a plane track

I then move the corners of the plane track to the four corners of the laptop screen

Compositing

I open the compositing workspace and activate use nodes

I can delete the render layers node

*I will also be using the node wrangler add-on

I import the movie clip using a movie clip node

I add an image node and open the image I will be using as a screen replacement

I add a mix color node and set the blending mode to screen

I connect the movie clip to the top image input and the image to the bottom image input

Using SHIFT + CTRL and clicking the mix node to see the footage and also add an output node

I add a plane track deform node to bring in the tracking information

I place this between the image and the mix node

I open the movie clip, camera, and the plane track

I also activate the motion blur

Render

I connect the mix color node to the composite node

Under the output tab, I choose where I want the footage to be rendered

I change the file format to FFmpeg and the encoding to Quick Time

Under the render menu, I render the animation
