Topaz AI stands out for its slow-motion videos, thanks to cutting-edge AI-powered frame interpolation technology, even from footage with low frame rates. Unlike traditional methods, it utilizes deep learning models to generate intermediate frames intelligently. This method enables the creation of extremely smooth, slow-motion effects with Topaz AI. With selectable AI models tailored for different content types—such as people, nature, or animation—it delivers unmatched quality in slow-motion rendering.
Pros
AI supplemental keyframes for smoother and more natural slow motion.
Fast motion or cluttered backgrounds also produce clear images without ghosting or artifacts.
AI ensures and even improves video quality.
Cons
AI algorithms consume a long time, and results are even slower with high frame rate videos.
Higher hardware requirements, especially graphics cards and memory.
Higher software subscription price.
There are fewer color mixing and cropping video features.
Frame Interpolation
The highlight of Topaz AI is its keyframe insertion technology. It intelligently analyzes the direction and speed of motion of each pixel in the video, and "predicts" and automatically inserts possible intermediate frames. This approach reduces ghosting, frame stretching, and other issues, even for dealing with fast-changing or complex backgrounds.
Customize Slow Motion Multiplier
It supports setting the slowdown ratio of the video, such as 2×, 4×, 8×, etc., and the system will automatically insert the corresponding number of frames. For example, a 30fps video will become 120fps after setting it to 4× slow motion. Additionally, it supports customization of the "target frame rate" (e.g., 60fps, 120fps, 240fps, etc.).
High-quality output support
It features built-in image enhancement algorithms that sharpen, reduce noise, and optimize color while slowing down. Even if the source material is of low resolution and poorly lit, you can still get a more precise, cleaner, and more detailed video output after slow-motion processing.
The Detailed Steps of Topaz AI Making Slow-motion Video
Step 1Install and launch Topaz AI. Click "Browse" or drag and drop to import the video you want to make into slow motion.
Step 2Click the "AI Models" section and select either the "Chronos" or "Chronos Fast" model. Chronos Fast offers faster processing with a slight drop in quality for quick previews.
Step 3In the "Parameters" or "Settings" section of the selected model, find the "Speed Adjustment" option. Then, choose the desired slowdown percentage. Or you can select the desired new frame rate.
Step 4Click "Output Settings" to change the video output format Then select the appropriate video codec and resolution. Click "Preview" to view a short clip of the video and see if the slow motion is smooth.
Step 5After verifying the settings, click "Start Processing". When finished, go to the folder and play the video to evaluate the results of the Topaz AI slow-motion video.
