🎬 Experimenting with AI Frame Interpolation on Flip Books

The video script introduces an experiment where the creator plans to use AI frame interpolation software to increase the frame rate of a flip book from 12 frames per second (fps) to 60 fps. The creator expresses skepticism about the quality of motion smoothing, especially on TVs, but is curious to see how a flip book would look with the increased frame rate. The process involves using a software called Rife to interpolate frames, and the creator discusses the challenges of achieving a clean video without blur frames. The experiment reveals that while the AI can create a smoother animation, it also introduces some unnatural elements, and the original crispness of the animation is somewhat lost in the process.


πŸ“Ή Stop-Motion Testing and AI Smoothing Results

The second paragraph discusses the creator's process of filming stop-motion versions of their flip books to test the AI frame interpolation. They then run these through the software to observe the results at an AI-generated 60 fps. The creator also shares their final test with a larger flip book, 'return of grumpy Cloud'. Upon review, they notice some oddities in the AI-generated frames, but also find it intriguing that 80% of the animation is artificially created. The creator, identifying as a purist, prefers the original animation and feels that motion smoothing lacks the intended impact and timing of the original work. They conclude that while the technology is fascinating, they remain unconvinced about the appeal of motion smoothing and invite viewers to share their opinions in the comments.




A flipbook is a simple animation device that consists of a series of images, usually drawings, printed on the pages of a small book. When the pages are turned rapidly, the images create an illusion of motion. In the video, the creator uses flipbooks as a base to experiment with AI frame interpolation, aiming to increase the frame rate from 12 to 60 frames per second.

πŸ’‘AI Frame Interpolation

AI frame interpolation is a process where artificial intelligence algorithms are used to generate intermediate frames between existing frames of a video or animation. This technique can increase the smoothness of motion by effectively raising the frame rate. In the context of the video, the creator applies AI frame interpolation to flipbooks to explore the effects on the animation's quality.

πŸ’‘Frames Per Second (FPS)

Frames per second (FPS) is a measurement of how many images (frames) are displayed in one second of a video or animation. Higher FPS generally results in smoother motion. The video discusses the conversion of a 12 FPS flipbook to a 60 FPS animation using AI, which is a significant increase in the smoothness of the animation.

πŸ’‘Artificial Motion Smoothing

Artificial motion smoothing is a technology used to enhance the motion in videos by creating additional frames that did not exist in the original footage. The creator of the video expresses a personal dislike for this technology on TVs, as it can make the motion appear fake. In the experiment, the creator examines the effects of artificial motion smoothing on the flipbook animations.


Rife is a term mentioned in the video that refers to a specific frame interpolation software used by the creator to increase the frame rate of the flipbook animations. The software is used to generate additional frames between the existing ones to achieve a higher frame rate.

πŸ’‘Stop Motion

Stop motion is an animation technique that involves physically manipulating 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 AI frame interpolation process.

πŸ’‘High Shutter Speed

High shutter speed refers to a camera setting that allows for a brief exposure time, which can freeze motion and eliminate blur in images. The creator uses a high shutter speed while re-filming the flipbook to ensure that each frame is crisp and clear, without the blur caused by the movement of the pages.

πŸ’‘Final Cut Pro

Final Cut Pro is a professional video editing software application used by the creator to edit the video of the flipbook. It is mentioned in the context of chopping up the video into individual frames and removing any blurred or duplicate images to prepare a clean 12 FPS video for the AI frame interpolation.

πŸ’‘Blur Frames

Blur frames are frames in a video or animation that contain motion blur, which is a visual effect resulting from rapid movement. The creator aims to remove these from the flipbook video to create a clean starting point for the AI frame interpolation process, as they can interfere with the interpolation of new frames.

πŸ’‘Snap and Impact

Snap and impact refer to the sharpness and forcefulness of movement in an animation. The creator argues that the AI-generated, overly smoothed versions of the flipbook animations lose their original snap and impact, which are crucial for conveying the intended feeling and timing of the movements.

πŸ’‘Wobbly Jello

The term 'wobbly Jello' is used metaphorically by the creator to describe the undesirable effect of over-smoothed animations. It implies that the motion appears unstable and lacks the crisp, defined movements that are characteristic of the original, non-interpolated flipbook animations.


The experiment aims to increase the frame rate of a 12fps flipbook to 60fps using AI frame interpolation software.

AI motion smoothing can artificially increase frame rates, but it may not always look better.

The creator is not a fan of artificial motion smoothing on TVs, as it can look fake and terrible.

Interpolating from 12fps to 60fps involves creating four artificial frames for every real frame, resulting in 80% of the final animation being fake.

The pencil flipbook is the first subject of the AI frame interpolation process.

The software used for frame interpolation is called Rife, which has many confusing settings.

The video of the flipbook at 24fps has redundant frames and blur, which complicates the interpolation process.

A clean video of the flipbook at 12fps with no blur frames is needed for better results.

Re-filming the flipbook with a high shutter speed helps to achieve crisp frames for the AI process.

After removing blur or duplicate frames, a clean video at 12fps is obtained for AI processing.

The AI frame interpolation process is very slow without a decent video card.

The final AI-processed animation shows some weirdness and loss of crispness compared to the original.

The creator prefers the original animation and believes that fake motion smoothing lacks the original animator's intention.

Motion smoothing can disrupt the timing and impact of the original animation, making it feel like 'wobbly Jello'.

The balloon flipbook is the most successful in the AI frame interpolation, appearing clean and less affected by the process.

Despite the weirdness, it's interesting to consider that 80% of the AI-generated animation didn't originally exist.

The creator encourages viewers to share their opinions on motion smoothing in the comments.

The video concludes by emphasizing the importance of staying creative and looking forward to the next video.
