And what are you basing this on? Where are you getting this "factor of 10" number from?
1) When
Sony where showing off their new 4k projector a month or so ago, EVEN they were unable to show off natural 4k media.
If it was as simple as some on here would have you believe, it woudlnt have been a challange. (Remember they wouldnt even need to do a whole film, they could have just done multiple clips etc). Most laptops have more than the required storage on their c drive (without relying on a slower usb device)
2) 4k reproduction is as near as **** it perfect, any film studio willing to release this in any means for public purchase are going to put some as yet unknown protection / encryption on it much beefier than anything seen as yet from BR - this will therefore use more storage than current protection methods for the known formats
3) As yet we have no way of knowing how said 4k film will be encoded - this will in all probabilty require different amounts of storage for starters than the present method for current BR. Without any direct knowledge, database files I believe get into 100's Gb in size, but what kind of size limits are there on other file formats?
4) As already highlighted, BR's file sizes currently range from 10Gb approx to about 50-60GB (over two discs for LOTR EE version), and from my knowledge of buying /owning 600 - 700 BR's myself I would suggest the average file size is growing (for the film itself since I bought my first one when the PS3 was originally released). We have NO WAY of knowning how large even the first 4k film - through standard distribution channels - will be.
5) I havent working out the ratio of pixel differences between Sd / Hi Def and then comparing dvd file sizes to BR file sizes - to try and work out a corrolation between hi -def /4k......
Just a few of the reasons why I dont believe 200Gb is going to be anywhere near what the end resultant file size will be
Everyone (including me) is guessing, as no -one knows for sure if / when 4k films are released for purchase how large they will be , however I do believe the above are a few reasonable points as to why they will be larger
Given that there was a brief mention of cinemas and digital projectors, we went to see The Hunger Games at the Odeon Cinema where I live the other day and they have digital projectors there.
Immediately, when the BBFC screen came on, you could actually see the pixels on the screen and it was quite surprising. You couldn't notice anything once the action started, but I was surprised to see square pixels, made me what resolution they do run at.
Have no idea if this is true or not - but being the BBFC produces that "slide" , it may be a standard hi def image rather than a 4k one - so it could have just been upscaled by the projector , and therefore made the pixels look horrendous?
