FPS Traditional vs CGI

Animation FPS: Traditional vs CGI

Frames per second (FPS) is how many distinct images you see each second. Animation pipelines pick their rate based on platform and style, and the math is straightforward: total_frames = duration_seconds × fps. Cinema settled on 24 fps. Broadcast TV runs 24/25/30 fps, web platforms handle anywhere from 24–60 fps, and high-frame-rate (HFR) showcases push 60–120 fps.

Traditional 2D feature animation (Disney, Studio Ghibli) is drawn at 24 fps, though almost never with a fresh drawing on every frame. The "limited animation" technique, invented by UPA and later popularized by Hanna-Barbera and Japanese anime, leans on drawings on twos (12 unique drawings/sec) or on threes (8/sec) to keep production costs down. Anime usually averages 8–12 unique drawings/sec, holding key poses and animating just the mouths or small accents. Modern CGI renders at 24–30 fps for a cinematic look, and Pixar deliberately stays at 24 fps to keep that filmic motion blur. Games, on the other hand, target 60 fps so input stays responsive, while HFR cinema reaches for 48–120 fps to keep fast action crisp.

Applications

Animators reach for it when budgeting a project, since the frame count is what drives the drawing labor. Video editors use it to match footage frame rates, game developers to lock in a target FPS, and motion graphics designers to plan work in After Effects. Indie filmmakers weigh the 24 fps cinematic look against 60 fps smooth motion. It also helps estimate render times for CGI projects and storyboard timing for traditional shots.

FAQ

Why does 24 fps still dominate cinema? After a century of viewing habits, audiences read 24 fps as "cinematic". Crank the frame rate higher and it can start to feel like a soap opera or a live broadcast — the so-called "soap opera effect".

Why do games need 60 fps if movies use 24? Games have to respond to input in real time, and a lower FPS means more input lag. Movies are pre-rendered with motion blur baked in, which smooths out how your eye reads the motion.

Is "on twos" lazy animation? Not at all. It's a stylistic choice. Hand-drawn animation on twos at 24 fps reads as more "drawn" and intentional, whereas on ones (24 unique drawings/sec) can come across as overly smooth and lose some of its line quality.
