Preparing the footage

There are not many restrictions on preparing the footage for this effect. However, depending on the results you're aiming for, you might need to consider a few things.

First, a wider view and some camera panning, or tilting will deliver a better result as it provides angle variations. This will later enhance the dynamic of the scene, making it feels even more uncanny.

Then, while you're at it, you need to also figure out the purpose of the video itself. If you want to upload it to certain platforms where vertical videos are more popular, you will want to work on that as well. When you're shooting your footage, make sure that you're taking it at the correct angle that would fit the ratio you're aiming for.

Last but not least, consider the length of the footage. If you're planning to make a bumper video, you might want a quick yet comprehensive shot of the objects you want to highlight. You can always trim and adjust the timing later, but it is better to also plan it early.

Editing the video

Enhancing the effect with rotation keyframes

If you're using stock videos or encountering limitations when making your footage, chances are your alternate reality is not looking as dynamic as you want it to be. Go all out by adding the rotation keyframes to the video footage so that the alternate reality looks more unreal.

Step 1: Double-click the video footage on the first video track to open the Animation Settings > Customize.

Step 2: Move the playhead to the beginning of the first video footage and add a keyframe by clicking on the Add button. Set the rotation of this keyframe at 0 and the scale at 100.

Step 3: Now move the playhead to the end of the video footage and add another keyframe. This time, set the rotation to 20 and adjust the scale number to 115.

Step 4: Do Steps 1 to 3 to the second video footage. Don't forget to preview the result to see if both footages are rotated properly.
