Part 1: What is a Video Upscaler and How does it Work?

The video upscaler is a tool that increases the resolution of a video, setting it apart from other video editing software. It is used to convert low-resolution videos to higher resolutions such as HD, 4K, or 8K. Video upscalers use algorithms to upscale the video by adding pixels to the original video frames, resulting in a higher resolution output.

Video upscalers work by analyzing the video frame by frame, detecting edges, and then adding pixels to the image. This process is called interpolation, and it helps to smooth out the edges and increase the detail in the video. Some video upscalers also use machine learning algorithms to enhance the image and produce a more realistic output.
