I calculated that for a film of 2 hours with 30 fps, over a 1920*1080 (16:9) display with 32 bps (True Colour) had to weight :
2×3600×30×1920×1080×4 Bytes which is
Is there something I didn't get right? Or is it that uncompressed, I could not have more than 1 film stored on my computer to watch on my very standard
Are the films that are shot and projected in 1080p really that size?
And my question is : if so how are Blu-Rays compressed into a measly 25-100 GB disk? I thought DVDs and such were lossless encodings and even if not how can we lose 95%+ of the information (100GB/2TB) and be ok watching it?
