Most effects can be added by just draging the Effect video to a layer over your background footage and add transparency using the Screen opacity mode trick on the effect controls panel. This works well with all Black screen video effects, which only need the black parts of the video to turn transparent.

Some effects will come with a green screen (or other colors) background, which require you to use a chroma key effect, usually "Keylight", where you simple need to select the color you want to remove and it will add transparency over the area removed.

Some people believe you need an advanced knowledge of After Effects to do visual effects on your video projects, but the truth is that with Good stock footage of pre-rendered effects, like the ones i share with you, there's a lot that can be done inside Premiere Pro.

Background info:

WandaVision is an American television miniseries for the streaming service Disney+, based on Marvel Comics featuring the characters Wanda Maximoff / Scarlet Witch and Vision.

The Scarlet Witch (Wanda Maximoff) is a fictional character appearing in American comic books published by Marvel Comics. The character was created by writer Stan Lee and artist Jack Kirby. Her first appearance was in The X-Men #4 (March 1964) in the Silver Age of Comic Books. Originally said to have the ability to alter probability, the Scarlet Witch has been depicted as a powerful sorceress since the 1980s and was later said to be powerful enough to alter reality. For most of her comic book history, she is portrayed as a mutant, a member of a fictional subspecies of humans born with an "X-gene" that grants superhuman abilities and traits. This was revised via a 2015 storyline establishing that her superhuman traits are a result of experimentation done by High Evolutionary when she was a child.

When the Scarlet Witch was first created by Lee and Kirby, her main ability was a vaguely defined "hex power" that could cause random and unlikely things to affect her enemies or other targets, often in the form of "bad luck." These effects could be unpredictable, however, and thus not always helpful to Wanda. The vague and unpredictable nature of her power meant Wanda could use her ability in a variety of ways that helped the plot but also meant she couldn't easily solve all her problems.

Despite the character's name, the Scarlet Witch's powers stemmed not from witchcraft or magic but from being a mutant who could affect probability. Later stories gave her increased control, allowing her to release targeted "hex-bolts" that could cause enemy weapons to backfire, their abilities to fail, or the area around them to suffer sudden damage and instability. Eventually, she also became adept at casting energy blasts that could directly stun opponents. She later realized her hex-bolts were the most basic use of chaos magic.^[76]

Writer Steve Englehart decided the character could become more powerful and formidable by living up to her name. His stories revealed Wanda had a strong talent for magic, possibly caused by the demon Chthon giving her latent magical talent as a child. Under Englehart, Wanda studies spell casting and the manipulation of magical forces under the tutelage of Agatha Harkness. Along with increasing her control over the effects of her hexes, this allows her to counter, deflect, and block a variety of magical attacks.
