How long would a video that takes up 1GB of space, uncompressed, while running on say, 480p or 720p? i'm trying to help my granddad be more efficient for his internet bill. he seems to be watching a lot of Youtube videos recently and it seems to be increasing his internet bill. I want to see if he needs a new internet plan or if he could solve his problem by watching his videos at a lower resolution. Thank you!
