What is the size of a true/real 1080p movie that is about two hours long?

Leonardus_gunawan 2011-08-30 13:52:00 What is the difference between uncompressed 1080p (7gb) and commercial blu ray movies (25gb). Is there any big difference in terms of video quality and sound? John Kiser 2011-11-09 11:59:00 the 7 gb is likely only uncompressed as far as video quality goes it likely has a lossy sound as opposed to lossless audio. Most of the smaller file sizes are compressed down audio wise Ravi 2011-07-06 08:08:00 Most files are around 8 gig and can go up to as high as 20gig mostly what you see online is that they compressed it into smaller file formats what mostly leads to quality lost. 2011-06-07 18:16:00 1080p vs 720p - What is the difference? (1080p) length is 1:04min and it weights 149 MBmovie (720p) length is also 1:04min and it weights 62.8 MB. From a total surface area standpoint, we can also calculate the number of individual pixels contained in each resolution:  480p = 338,000 pixels / frame 720p = 922,000 pixels / frame 1080i = 1,037,000 pixels / frame 1080p = 2,074,000 pixels / frame In other words, 1080p represents about twice the amount of the resolution information as standard HD and contains six times the information in DVD resolution.

Jeffery Fabish 2011-06-07 16:29:00 I would estimate about 3 to 4 GB's
