Not everyone has fiber optic broadband. Many rely on 2-10 Mbps connections. A 300MB movie downloads in 10-15 minutes, while a 10GB movie takes 6+ hours.
Laptops have larger screens where 480p resolution will start to look blurry and pixelated. A 720p file offers a great balance of HD quality without taking up massive amounts of hard drive space. 📺 Big Screen TVs and Home Theaters Best Choice: 1080p (or higher).
Rip your own DVDs/Blu-rays using MakeMKV and compress with HandBrake to 300MB or any size you prefer. Completely legal (in most countries) for personal backup.
If you're looking for a more immersive viewing experience, you may want to opt for 720p or 1080p videos. These resolutions offer significantly better image quality than 480p, with more detailed and crisp visuals.
