Keywords

💡Flipbook

A flipbook is a simple form of animation that consists of a series of images, usually drawings or photographs, arranged in order on the pages of a small book. When the pages are turned quickly, the images give the illusion of movement. In the video, the creator uses flipbooks as the base for his experiment to see how AI can interpolate frames to increase the frame rate.

💡A.I. frame interpolation

Artificial Intelligence (A.I.) frame interpolation is a technique that uses machine learning algorithms to generate additional frames between existing ones, effectively increasing the frame rate of a video. In this context, the creator is interested in using A.I. to boost the frame rate of his flipbooks from 12 frames per second (fps) to 60 fps.

💡Motion Smoothing

Motion smoothing, also known as the 'soap opera effect,' is a feature on some televisions that uses algorithms to add extra frames to video content, making it appear smoother. The creator expresses his personal dislike for this feature, finding it to look fake and detracting from the original intention of the content.

💡Frames per second (fps)

Frames per second (fps) is a measure of how many images (frames) are displayed in one second of video. Higher fps values generally result in smoother motion. The video discusses increasing the fps from the standard 12 to 60, which is a significant increase that would normally require a lot of additional animation work.

💡Interpolation

Interpolation is the process of estimating unknown values between known points. In the context of video, it refers to the creation of new frames between existing ones. The script mentions that 80% of the frames in the final animation would be generated through this process, which is a high percentage that can affect the authenticity of the animation.

💡Rife

Rife is a term mentioned in the script referring to a specific frame interpolation software the creator uses to experiment with increasing the frame rate of his flipbooks. It's part of the process to see the effects of A.I. on the motion of the flipbook animations.

💡Stop motion

Stop motion is a type of animation that physically manipulates objects to create the illusion of movement. The creator mentions shooting the flipbook pages one at a time as a stop motion to create a clean video without blur frames, which is then used for the A.I. frame interpolation process.

💡High shutter speed

High shutter speed is a camera setting that allows for quick exposure times, reducing motion blur in images. The creator uses a high shutter speed to film the flipbook slowly, ensuring each frame is crisp and clear without motion blur, which is essential for the frame interpolation process.

💡Final Cut Pro

Final Cut Pro is a professional video editing software used by the creator to edit the video of the flipbook. It's where he chops up the video into individual frames and removes any blurred or duplicate images to prepare a clean 12 fps video for the A.I. frame interpolation.

💡Purist

A purist is someone who prefers things to be true to their original form without artificial enhancements. The creator identifies as a purist, preferring the original 12 fps flipbook animations over the A.I. smoothed versions, which he feels lose the original intent and timing of the animations.

💡Snap and Impact

Snap and impact refer to the sharpness and forceful nature of the original animations. The creator feels that the A.I. smoothed versions of the flipbooks lose this quality, making the movements feel less impactful and more like 'wobbly Jello.'

💡Wobbly Jello

Wobbly Jello is a metaphor used by the creator to describe the undesired effect of the A.I. smoothed animations. It implies that the motion appears unstable and lacks the crisp, defined movements of the original flipbook.
