There are a few ways that you can get a 3D look using 2D images. Ina ll cases, a parallax effect is the key. If you are using HitFilm, it has a great displacement effect that you can use to essentially “pop” 2D elements into 3D space. If you have used After Effects before, then HitFilm’s Displacement effect will feel similar, albeit easier to manage and faster.
If you want to take a look at what the process for using displacements for creating pseudo-3D objects and an easy parallax effect, Mike Miller from Triem Visuals walks us through it in HitFilm. In this demonstration, he is using HitFilm Express, which, if you didn’t know, is absolutely free and cross platform, and totally fun if you are just getting started or want to kick the tires.
