What Are Frames in Animation?

In animation, a frame is a single still image. When many frames are played in sequence at a fast rate (typically 24 to 30 frames per second), they create the illusion of motion.

In 3D animation, frames are used to define key points in an object’s motion, known as keyframes.

Why Frames Matter in 3D Animation?

• Defines timing and speed of movement

• Helps create smooth motion

• Allows animators to control how a body moves over time

• Enables complex character movements like walking, running, jumping

How to Set Frames for Animating a Body in 3D

Let’s say you’re using software like Blender, Maya, or 3ds Max:

---

Step-by-Step: Set Up Frames for Body Animation

Step 1: Set FPS (Frames Per Second)

Choose the desired playback speed:
24 FPS – film standard
30 FPS – for games
60 FPS – high-end smooth animation

---

Step 2: Select the Body or Object to Animate

• Import or create your 3D character model (humanoid, creature, etc.)

• Make sure it’s rigged (has a skeleton/bones)

---

Step 3: Set Keyframes on the Timeline

For example, animating a walk cycle:

Set keyframes for each pose by selecting the bone/joint and pressing the “Insert Keyframe” button (or I in Blender).

---

Step 4: Use Interpolation

The software will automatically generate the movement between keyframes using interpolation.

You can customize the motion with:

• Linear interpolation (constant speed)

• Bezier/Ease-in Ease-out (natural acceleration)

---

Step 5: Refine Using Graph Editor or Dope Sheet

Tweak the:

• Speed of movement

• Curves of rotation or translation

• Overlap and follow-through for realism

---

Step 6: Preview and Render

• Use the Play button on the timeline to preview

• Adjust frames as needed

• Once smooth, render the final animation

---

Example: Body Jump Animation

Add keyframes at each of these, and let interpolation create smooth motion in between.

---

Pro Tips:

• Use reference videos to understand timing

• Animate the core body mass first (hips/spine)

• Keep frames spaced evenly for smoother results

• Use onion skinning or motion trails to visualize path
