YouTube is launching a new initiative to enhance video quality across its platform. The company has introduced an AI-powered feature that automatically upscales low-resolution videos to 1080p HD, with plans to eventually support 4K upscaling. Importantly, creators maintain full control over their original content—meaning the source videos remain unchanged, and only AI-generated higher-resolution versions are added. Creators can experiment with this technology without losing access to their original files.
This AI upscaling feature will be enabled by default, though users can opt out if they prefer to watch videos in their native resolution. When content is enhanced using AI, it will be clearly labeled as “super resolution” so viewers are aware they’re watching an upscaled version.
YouTube’s vast content library spans over two decades, including many older videos filmed on early smartphones, camcorders, and outdated equipment. While most recent uploads are already in high definition, it is uncertain if the AI upscaling will be applied retroactively to older footage. Nonetheless, the ability to view classic content, such as early 1980s sports highlights, in HD could be an appealing feature for many.
In addition to video quality improvements, YouTube is rolling out a redesigned video player with a cleaner interface and more precise controls. The new design aims to enhance user navigation without distracting from the video itself. This update began rolling out two weeks ago and will gradually become available to all users.
YouTube is also enhancing its comments system by introducing a structured threading format, which makes it easier to follow and engage in conversations within the replies panel. This change is intended to create a more focused and organized reading experience.
Creators will also benefit from an increased thumbnail file size limit, expanding from 2MB to 50MB, allowing for higher-resolution preview images.
Finally, YouTube is working on a feature that mimics “channel surfing” on TV. Soon, users will be able to browse subscribed channels using immersive previews on the homepage, making content discovery more engaging and intuitive. Although this may encourage longer viewing
