Blender How to insert keyframe with shortcut for setting 3D animation

This video tutorial explains how to add keyframes in Blender for animation using the default scene. It guides through selecting an object, such as the default cube, opening the timeline, and adjusting the time frame to insert keyframes using either the insert keyframe panel or the shortcut 'I'. The demonstrator chooses to use location, rotation, and scale options for setting keyframes and explains that the orange dot on the timeline indicates where a keyframe has been added. They show how to move to the next frame and adjust values, using tools like move, rotate, and scale, to set another keyframe, which creates an animation when previewed. The tutorial also covers adding keyframes for modifiers. By going to the modifier properties and adding a bevel modifier, viewers are shown how to set keyframes for it to animate changes in the edge over time. The process of adjusting and replacing keyframes is also demonstrated, ensuring changes are updated and creating a seamless animation. The tutorial ends by illustrating how to copy and paste keyframes to the last frame to complete the animation.
