Show HN: Video Upscaler – AI video upscaling up to 4K
The article introduces a video upscaler tool that uses AI to enhance video resolution up to 4K. It advises users to assess the source quality before upscaling, recommending stable clips with clear details for optimal results. For heavily compressed footage, it suggests applying a denoise or restoration mode first to avoid harsh edges.
- ▪Check the source file quality before using the AI upscaler to ensure better results.
- ▪Use short, stable clips with visible faces, text, or scene detail to give the AI more information.
- ▪If the video is heavily compressed, select a denoise or general restoration mode before upscaling to improve quality without creating harsh edges.

01 | CHECKPOINTChecking source qualityStart by checking the source file before you upscale video online. A short, stable clip with visible faces, text, or scene detail gives the AI video enhancer more information to work with. If the video is heavily compressed, choose a denoise or general restoration mode first so the video quality improves without creating harsh edges.
