What is the Difference between 720p and 1080p?
I was about to purchase HD movies on my Mac from iTunes store to stream to my iPod touch (4th generation) for watching. However, I got a problem here because I realized some movies are providing two HD versions (720p and 1080p) for downloading. What's the difference between 720p and 1080p? As in my case, which should I download?
As we know, ever since iTunes 10.6, Apple has added the support for streaming and purchasing 1080p HD movies and TV shows via iTunes Store. Although it gets higher resolution for a 1080p video, the price is the same as the previous 720p HD's. Expectedly, it has successfully raised customers' purchasing desire for 1080p movies over the ones of 720p. But have you ever thought about this? Is it really worthy of such an overwhelming pursuit for 1080p movies on iTunes if putting aside the better image quality? Is 1080p iTunes movie the right one for you or your devices? Now you may take some time to figure it out from the side-by-side comparison between 1080p and 720p HD iTunes movies to make a better decision when buying HD movies from iTunes.
Video Resolution & Quality: 1080p is Higher & Better than 720p
As suggested from the number, 1080p which refers to video resolution of 1920x1080, will apparently presents better video quality than 720p that refers to a resolution of 1280x720 only. Theoretically, 1920x1080 means 2.25 times as many pixels as 1280x720. That's to say, the image quality of 1080p movies is much sharper and smoother than 720p and will definitely bring more visual enjoyment to you while watching the movies.
File Size & Storage: 1080p is Bigger than 720p
From a file size point of view, a 1080p HD movie download is expected to be approximately 50% larger than the 720p counterpart. For example, if the file size of a 1080p HD movie on iTunes is 1GB, the 720p version of it would probably be around 700MB. And at mean time, a bigger file size always requires more storage of your computer or devices. So you'd better take the file size into consideration to decide whether download 1080p or 720p movies according to your situation.
Compatible Devices: 720p Supports More Devices than 1080p
Even though 1080p looks much better than 720p, not all your devices are capable of playing it back. As of now, iOS devices including iPhone 5 or later, iPad (3rd generation or later), iPod touch (5th generation or later), and Apple TV (3rd generation or later) are supposed to play back 1080p content. So if you primarily watch your iTunes movies and TV shows on none of those models, 720p is all you can play. Besides, most of the iOS devices which support 1080p can absolutely support 720p too. That makes the choice simple, though.
Number for Movies: 720p Gets More Movies than 1080p
One more important thing to note is that the iTunes Store has not seen a wholesale updating of HD content into 1080p, which means, many HD movies sold on iTunes continue to be available only in the older 720p resolutions. At this point it doesn't appear that any content is exclusively 1080p — sensible considering the number of Apple devices out there that are still limited to 720p as their "HD" resolution.
Conclusion & Suggestion
There is no absolute statement or clarification to prove whether 1080p or 720 is better. What you should keep in mind is that the most right option will always be the one that meets you needs better. If you prefer a more direct way to look at the difference between 720p and 1080p HD movies, you can simply download a movie with both 720p and 1080p to compare by yourself.
