Question: Is there a video editing tool that can stabilize and sharpen footage, and also upscale to high resolutions?

For a full-featured video editing tool that stabilizes and sharpens video and upconverts to high resolution, check VideoProc. This software employs AI for video enhancement, stabilization and upconversion. It's fully GPU accelerated, so it's fast for 4K and 8K video. VideoProc also includes some editing tools and can transcode audio, too, so it's good for processing video as well as just improving it.

Another good option is Topaz Labs, a collection of professional-grade video and photo editing software that uses deep learning technology. The Video AI 5 tool handles video stabilization and sharpening, and Gigapixel 7 can upconvert video resolution dramatically. Topaz Labs' software is geared for pros who want high quality and don't want to send their data to servers.

AVCLabs also offers a variety of AI-powered tools to improve video quality, including Video Enhancer AI, which upconverts low-resolution video to high resolution while denoising and deinterlacing for better quality. It's good for both beginners and pros who want to improve video quality without a lot of fuss.

And TensorPix offers a cloud-based service for video and image improvement. It uses GPU-accelerated servers to upconvert video and remove noise, and can also handle tasks like background removal and framerate increase. TensorPix is accessible to people who don't have a lot of editing experience, so it's a good option for people who want to improve their multimedia assets.
