Keyframing is a fundamental concept in animation that involves setting specific values for an object's properties at certain points in time. Blender then interpolates the values between these keyframes to create smooth transitions. This module will cover the basics of keyframing, including how to set keyframes, understand interpolation, and manage keyframes using Blender's tools.

1. Keyframe: A marker that defines the value of a property at a specific point in time.
2. Interpolation: The process of calculating intermediate values between keyframes to create smooth transitions.
3. Timeline: A visual representation of time in your animation, where keyframes are placed.
4. Dope Sheet: A tool for managing keyframes and adjusting timing.

1. Select the Object: Click on the object you want to animate.
2. Choose the Property: Decide which property you want to animate (e.g., location, rotation, scale).
3. Set the Initial Keyframe:
   • Move to the desired frame on the timeline.
   • Press I to bring up the Insert Keyframe Menu.
   • Choose the property you want to keyframe (e.g., Location, Rotation, Scale).
4. Move to the Next Frame: Advance the timeline to the next point where you want to set a keyframe.
5. Change the Property Value: Adjust the property value (e.g., move the object to a new location).
6. Set the Next Keyframe: Press I again and choose the same property to set the new keyframe.

Blender uses different interpolation methods to calculate the values between keyframes. The default method is Bezier, which creates smooth, curved transitions. Other methods include Linear (straight-line transitions) and Constant (no transition, sudden change).

1. Select Keyframes: In the Timeline or Dope Sheet, select the keyframes you want to change.
2. Right-Click: Right-click on the selected keyframes.
3. Choose Interpolation Mode: Select the desired interpolation mode from the context menu (e.g., Linear, Bezier, Constant).

• Add Keyframes: Press I to insert keyframes.
• Delete Keyframes: Select the keyframe and press X or Delete.
• Move Keyframes: Select and drag keyframes to a new position on the timeline.

The Dope Sheet provides a more detailed view of your keyframes and allows for more precise control.

• Select Keyframes: Click and drag to select multiple keyframes.
• Move Keyframes: Press G to grab and move selected keyframes.
• Scale Keyframes: Press S to scale the timing of selected keyframes.

Animate a cube to move from one corner of the scene to another over 100 frames.

1. Open Blender and create a new project.
2. Select the Cube: Click on the default cube.
3. Set the Initial Keyframe:
   • Move to frame 1 on the timeline.
   • Press I and select Location.
4. Move to Frame 100: Advance the timeline to frame 100.
5. Move the Cube: Drag the cube to a new location.
6. Set the Final Keyframe: Press I and select Location.

• Forgetting to Set Keyframes: Always remember to press I to set a keyframe after changing a property.
• Incorrect Frame Selection: Ensure you are on the correct frame before setting a keyframe.
• Interpolation Issues: If the animation doesn't look smooth, check the interpolation mode and adjust as needed.

Keyframing is an essential skill for animating objects in Blender. By understanding how to set keyframes, manage them, and control interpolation, you can create smooth and dynamic animations. Practice these techniques to become proficient in keyframing and prepare for more advanced animation topics.
