Unlocking the Secret of the “Twixtor Cartoon”: How Slow Motion Became a Viral Animation Style If you have spent any time on YouTube, TikTok, or Instagram Reels in the last few years, you have almost certainly seen it: a cartoon character—often from SpongeBob SquarePants , The Amazing World of Gumball , or Family Guy —suddenly gliding across the screen in impossibly smooth, fluid slow motion. The background blurs into a streaky mess, the character’s limbs stretch into liquid appendages, and the frame rate seems to jump from 12fps to an unnatural 1000fps. This effect is widely known as the "Twixtor cartoon." But what exactly is Twixtor? How does a plugin designed for Hollywood visual effects end up being the cornerstone of surreal memes and trippy animation edits? And most importantly, how can you create your own Twixtor cartoon effect? This article breaks down the history, the science, the software, and the step-by-step process to mastering this iconic internet aesthetic.
Part 1: What is Twixtor? (The Software Behind the Meme) Before we talk about cartoons, we have to talk about the plugin. Twixtor is a time-warping (slow-motion) plugin developed by RE:Vision Effects. It is available for major editing platforms like Adobe After Effects, Premiere Pro, Final Cut Pro, and DaVinci Resolve. Unlike standard slow-motion (which simply stretches existing frames, resulting in choppy playback), Twixtor uses a process called optical flow . It analyzes the pixels in Frame A and Frame B, calculates where each pixel moved , and then synthesizes brand new, fake frames in between. The result? A perfectly smooth slow-motion video that looks like it was shot at 1,000 frames per second. Why Twixtor is Dangerous (and Beautiful)
The Good: It turns 24fps footage into 960fps slow motion. The Bad: It hates motion blur, occlusion, and quick cuts. When it fails, you get the "melting" effect—warping, liquid distortions, and digital artifacts.
That "failure" is exactly what the internet fell in love with. twixtor cartoon
Part 2: The Birth of the "Twixtor Cartoon" Aesthetic Cartoons are traditionally animated "on twos" (12 unique frames per second) or "on ones" (24 frames per second). They rely on smear frames —exaggerated, blurred drawings that simulate fast motion. When you run a cartoon through Twixtor, the plugin tries to interpolate between these smear frames. But because the smear frames are not realistic motion (they are artistic exaggerations), Twixtor gets confused. It creates bizarre, inhuman, gorgeous artifacts. Arms turn into taffy. Faces melt off skulls. A simple punch becomes a liquid explosion of color. The Viral Origin The trend exploded around 2017-2018 on YouTube channels like CrispyToast and Pieguyrulz . Editors started taking scenes of violent animation (e.g., Tom and Jerry getting hit with a frying pan) and slowing them down to 1% speed using Twixtor. The combination of brutal cartoon violence and buttery-smooth, ethereal slow motion created a hypnotic, hilarious, and strangely beautiful effect. The hashtag #twixtor on TikTok now has millions of views, with "Twixtor cartoon" being a top related search.
Part 3: How to Make a Twixtor Cartoon (Step-by-Step Guide) Ready to make your own viral slow-motion cartoon edit? Here is the definitive guide. We will focus on Adobe After Effects , as it is the industry standard. Step 1: Source the Right Cartoon Clip You cannot just use any cartoon. Twixtor works best (or fails spectacularly) on clips with:
Fast, frantic motion (road runner running, characters fighting). High contrast (bright characters against dark backgrounds). Low background detail (simple, flat backgrounds like Fairly OddParents ). Avoid: Slow dialogue scenes or incredibly detailed anime (the algorithm chokes). Unlocking the Secret of the “Twixtor Cartoon”: How
Step 2: Import and Interpret Footage
Import your clip into After Effects. Right-click the footage in the Project Panel → Interpret Footage → Main . Set the frame rate to match the source (usually 23.976 or 24fps). Do not change this yet.
Step 3: Apply Twixtor
Drag your cartoon clip to a new composition. Go to Effects & Presets → Search for Twixtor (you must purchase/install it first). Drag Twixtor onto your clip.
Step 4: Set the Slow Motion This is the most critical part.
