To convert a low-resolution picture to a high-resolution picture on a MacBook Air, you can use image editing software like Adobe Photoshop or GIMP. Open the image in the software, then use the "Image Size" feature to increase the resolution, ensuring you select options like "Preserve Details" for better quality. Alternatively, you can use online tools or apps that utilize AI upscaling to enhance the resolution while minimizing quality loss. Remember that upscaling won't create new detail but can improve appearance.

I think this is so called restoration you can do this by means or using an especial equipment or hardware. Generally you can't get a low resolution video to a high resolution, some of these restorations can work to varying degrees.
