X (formerly known as Twitter) is introducing support for 4K video uploads, aiming to enhance its platform's appeal to content creators and compete more directly with video-centric platforms like YouTube and Vimeo.
As of April 30, 2025, select creators have been granted the ability to upload videos in 4K resolution. The company plans to extend this feature to all premium subscribers in the near future, as announced by X’s engineering team.
This move is part of X's broader strategy to bolster user engagement and retain creators by offering enhanced video capabilities. Previously, X allowed video uploads up to 1080p resolution, with premium users having access to longer video durations and larger file sizes. The introduction of 4K support aligns X more closely with platforms that prioritize high-resolution content.
In addition to 4K uploads, X has been testing variable video upload quality options, allowing creators to select the desired resolution for their content. This feature provides flexibility, catering to users with varying bandwidth and storage considerations.
The rollout of 4K video support underscores X's commitment to evolving its platform to meet the needs of modern content creators and audiences seeking higher-quality video experiences.
