4k export

The 4k export tag on WindowsForum.com collects discussion of exporting video at 4K resolution from Windows software, most recently Microsoft Clipchamp. Tagged coverage describes Clipchamp's AI-powered video upscaling in the Windows desktop app, which can enlarge lower-resolution clips to as high as 4K on compatible devices. The feature targets older phone videos and webcam recordings, keeps the original footage available, and lets users choose the final export resolution separately from the upscaling step. Discussion also touches on hardware eligibility, including testing on a laptop without an NPU, plus questions about image accuracy and how source resolution affects available targets.
