Mesmerize: Create Mind-Bending GIFs with After Effects and Photoshop

A narrow course that does its narrow job well

Mesmerize is not a general After Effects course, and it does not pretend to be. Its entire premise rests on one mathematical trick explained early on: if a shape has six points and you rotate it by exactly 60 degrees (360 divided by 6), the loop point becomes invisible to the eye. That single insight, delivered in the "Simply Seamless" lesson while animating a star-shaped flower, is the spine every later project hangs from. Once the principle lands, the course spends its remaining runtime showing variations on the same trick: opposing rotations, offset falling elements, randomized duplicates, and a five-layer rocking letterform in the closing bonus video.

The nine-part "Principles of Mesmerization" lesson is the closest thing to theory the course offers, and it earns its place. Repetition, position, state change, rotation, multiplicity, color, speed, and interest are laid out as a practical checklist rather than abstract design philosophy, and every subsequent project visibly applies two or three of them at once. That structure, principle then immediate demonstration, is the course's strongest organizational choice.

Where the projects deliver

The middle stretch, covering rolling flowers, falling flowers, and endless ripples, is the meat of the class. Rolling Flowers teaches layer duplication and offset positioning to fake infinite horizontal motion using only five duplicated layers instead of a genuinely long animation. Falling Flowers pushes further by sequencing duplicated precompositions with staggered start times and then cropping the work area to a narrow window, a clever way to generate a compound effect from one short base loop. These lessons teach transferable technique, not just a single result: once the pattern of duplicate-offset-sequence is understood, it applies far beyond flowers.

The Photoshop export lesson is unusually practical for a course this short. It walks through the actual platform requirements, Instagram wanting three-second minimum clips versus Dribbble wanting specific pixel dimensions, and shows how color count and canvas size trade off against GIF file size in the Save for Web dialog. That kind of production-pipeline detail is often skipped in animation courses that stop at the render queue.

Where it thins out

The bonus material is where the course strains against its beginner label. The final bonus lesson introduces JavaScript expressions for randomizing position, scale, rotation, and hue across dozens of duplicated layers, plus parenting chains and graph editor easing with specific velocity influence values. This is genuinely advanced After Effects work dropped into a course that opens by promising to go slow for newcomers. It is clearly marked optional, but a viewer who skips it misses the most sophisticated technique on offer, and one who attempts it may find the pace jarring compared to the earlier lessons.

The course also never explains After Effects fundamentals like the graph editor, expressions syntax, or the render queue in isolation. Everything is taught in service of the immediate project, which keeps momentum high but means a viewer who wants to understand the tool broadly, rather than just replicate five loop projects, will need supplementary material. As a focused technique course rather than a software foundation course, it succeeds; as a first-ever animation class, it asks more of the viewer than its billing suggests.
