I don't know if this is the correct place to ask this type of question, but here is it. I wanted to find a ball park size of each blu-ray frame size in bytes. This is my calculation which cannot be correct.
Assuming we have a 2 hour blu-ray movie of size 25GB:
(25 * 1024) / (2 * 3600) = 3.56 MB/s of data
Blu-ray's fps ranges from 25-59 fps:
3.56 MB/s / 25 = 145 KB
That is around 145 KB for each 1910 x 1080
pixel picture?! I don't know what I'm doing wrong here...
