What Is AI Video Upscaling?

AI video upscaling is the process of upscaling a video using artificial intelligence. Instead of merely scaling up the size of pixels like your typical upscaler does, the AI models analyze each frame and can make their own guesses about what sorts of details got lost and assemble more realistic and sharper images.

One such example is the ability to upscale a 720p video to a 4K: natural edges, textures, and motion resolution are well-preserved as well. The result? Your footage would appear as if it were shot with a professional camera, without the need for one.

AI-based models use deep learning on millions of visual patterns. They understand textures, lighting, and colors in the real world and then smartly fill in the missing visual information frame by frame.

Why You Should Resample Video to 4K

Now you may be wondering: “Is this 4K business really worth it?” In most cases — absolutely. Here’s why:

Which enhances retention of consumers: The consumer is more likely to watch the videos that appear aesthetically pleasing and pass it on.

Old Footage Rehabilitation: Improve your old home videos or marketing material or low-res footage with the help of AI upscalers.
