What animation is and how it works
Animation is the process of creating the illusion of movement by displaying a series of still images in rapid sequence. Each image is slightly different from the one before it, and when played back at speed — typically 24 frames per second for film or 60 frames per second for video games — your eye perceives continuous motion instead of individual pictures.
The core principle is the same whether you are making a two-second animated GIF, a short video clip, or a feature film. You create multiple drawings or images, arrange them in order, and play them back fast enough that the changes blend together. The more frames you create and the smaller the changes between them, the smoother the motion appears.
Animation divides into two main approaches: frame-by-frame animation, where you draw or create each image individually, and motion graphics or tweening, where you define a start state and an end state and software calculates the frames in between. Most modern animation uses a combination of both.
Key Takeaways
- Animation requires either drawing each frame by hand or defining start and end positions and letting software fill in the motion between them.
- The most common software for beginners includes Blender (free, 3D), Aseprite (paid, pixel art), Adobe Animate (subscription, vector), and Pencil2D (free, hand-drawn).
- Frame rate — how many images play per second — affects how smooth motion looks; 24 fps is standard for film and 60 fps for interactive media.
- You do not need expensive tools to start; free software like Blender and Pencil2D can produce professional results once you learn the workflow.
- Most animators spend more time planning (storyboards, rough sketches) than actually creating frames, so preparation saves hours of rework.
Choosing between 2D and 3D animation
The first decision is whether to work in two dimensions (flat images) or three dimensions (objects in virtual space). Each path uses different tools and requires different skills.
2D animation means drawing or painting frames, either by hand or digitally. You create artwork on a flat canvas, and each frame is a separate image file. This is the approach used in traditional cartoons, motion graphics, and animated GIFs. It requires drawing ability or a willingness to develop it, but the software is often simpler and faster to learn.
3D animation means building digital models (like clay sculptures in a computer), positioning them in a virtual space, and moving them frame by frame. A camera in that virtual space records what it sees. This is how Pixar films, video game characters, and product visualizations are made. It requires understanding spatial relationships and how lighting works, but once a model is built, you can rotate it, light it, and film it from any angle without redrawing.
Start with 2D if you want to see results quickly or if you already draw. Start with 3D if you prefer working with objects and don't mind a steeper learning curve upfront.
Free and paid software for different animation types
The tool you choose depends on what kind of animation you want to make and how much you want to spend. Here are the most common options:
| Software | Cost | Best for | Learning curve |
|---|---|---|---|
| Blender | Free | 3D animation, character rigging, visual effects | Steep — plan 40+ hours before you make something finished |
| Pencil2D | Free | Hand-drawn 2D animation, frame-by-frame work | Gentle — similar to drawing on paper |
| Aseprite | $20 one-time purchase | Pixel art animation, sprites for games | Moderate — straightforward if you know pixel art |
| Adobe Animate | $23/month subscription | Vector animation, web animation, interactive content | Moderate — familiar if you know Adobe software |
| Krita | Free (or $10 suggested donation) | Digital painting and 2D animation combined | Moderate — designed for artists |
| Toon Boom Harmony | $20–50/month subscription | Professional TV and film animation | Very steep — industry standard, requires training |
If you have never animated before, start with Pencil2D (if you want to draw) or Blender (if you want to work in 3D). Both are free, and both have large communities posting tutorials. Avoid subscription software until you know whether animation is something you want to continue.
The basic workflow: planning, rough animation, and cleanup
Most animators follow the same sequence, whether they are working in 2D or 3D. Skipping steps usually means redoing work later.
Start with a storyboard — a series of rough sketches showing what happens in each shot. This takes 30 minutes to an hour but saves you from animating scenes you will later cut. Next, create key frames — the important poses or positions that define the motion. If a character is jumping, the key frames are: standing, crouched, at the peak of the jump, and landing. These are usually spaced far apart.
Then fill in the in-between frames — the images between the key frames that make the motion smooth. In 2D, you draw these by hand. In 3D, you often use the software's tweening feature to calculate them automatically, then adjust them if they look wrong. Finally, add cleanup — fixing lines, adding color, adjusting timing, and polishing details.
The ratio of time spent is roughly: 20% planning, 30% key frames, 40% in-betweens, 10% cleanup. If you skip planning, you will spend that 20% redoing key frames instead.
Frame rate and timing: how fast to play your animation
Frame rate is how many images play per second, measured in frames per second (fps). The frame rate you choose affects how much work you do and how the motion feels.
24 fps is the standard for film and most online video. It is the minimum speed at which motion looks smooth to the human eye. Animating at 24 fps means you create 24 images for every second of finished animation.
12 fps is sometimes used for stylized or limited animation (like some web cartoons or indie games). Motion looks slightly choppy, which can be intentional. You create half as many frames, so it is faster to produce.
60 fps is standard for video games and interactive media. Motion looks very smooth, but you create 2.5 times as many frames as 24 fps. Use this only if your software and hardware can handle it.
Start at 24 fps. Once you understand timing, you can experiment with lower rates for stylized work or higher rates for very fast motion.
Common mistakes beginners make
Most new animators repeat the same errors. Knowing them in advance saves frustration.
Animating without a plan. Jumping straight into drawing frames without a storyboard or key frame sketch means you will redraw scenes multiple times. Spend 15 minutes sketching the motion first.
Making changes too small. Beginners often move objects or characters only slightly between frames, which makes motion look stiff or slow. Exaggerate the movement — animation is not realistic, it is the illusion of realism. A character's arm should swing noticeably larger than it would in real life.
Ignoring spacing and timing. The distance between frames controls how fast something moves. If you space frames evenly, motion looks robotic. If you bunch frames close together at the start of a movement and spread them out at the end, motion looks natural. Study how real objects move before you animate them.
Working at the wrong resolution. Starting a project at 640×480 pixels and then trying to export it at 1920×1080 will look blurry. Set your canvas size and frame rate before you begin.
Resources for learning animation
Most animation software comes with built-in tutorials, and YouTube has thousands of free walkthroughs. The best approach is to pick one tool and follow a single tutorial series from start to finish, rather than jumping between many tutorials.
For Blender, the official Blender Studio has free courses on their website. For Pencil2D, the documentation includes step-by-step guides. For Aseprite, the creator has posted pixel art animation tutorials. Search for "[software name] beginner tutorial" and pick a series that shows you how to make something simple — a bouncing ball, a walking cycle, or a short scene — from start to finish.
After you complete one tutorial, make something of your own using the same techniques. This is where real learning happens. Copying a tutorial teaches you the buttons; making your own project teaches you how to solve problems.
Frequently Asked Questions
Do I need to be able to draw to make animation?
Not if you work in 3D — you build models instead of drawing them. If you want to make 2D animation, drawing skill helps but is not required. You can learn to draw while learning to animate. Start with simple shapes and characters, and improve over time.
How long does it take to animate one second of video?
At 24 fps, one second requires 24 frames. A beginner might spend 30 minutes to an hour per frame for detailed 2D work, so one second could take 12 to 24 hours. 3D animation is often faster once the model is built, because the software calculates motion between key frames. Professional animators work faster through practice and shortcuts.
Can I animate on a tablet or phone?
Yes, but it is slower than a computer. Apps like FlipaClip and Animation Desk run on tablets and phones, but they lack the power and precision of desktop software. If you own a tablet, try one of these apps to see if you like animation before investing in a computer setup.
What is the difference between animation and motion graphics?
Animation usually means creating characters or objects that move and act. Motion graphics means moving text, shapes, and visual effects to tell a story or explain an idea — think of title sequences or explainer videos. Motion graphics often uses tweening and effects rather than frame-by-frame drawing, and is usually faster to produce.
Do I need a powerful computer to animate?
For 2D animation, a basic laptop is fine. For 3D animation, a faster processor and more RAM help, especially when rendering (converting your animation into a video file). You do not need a gaming computer, but a machine with at least 8 GB of RAM and a modern processor will save you time waiting for software to respond.
