Oh, my… the calculation looks gorgeous, but there's hardly any meaning there. Exactly as the previous posts object:
raw != lossless!!!
When one says lossless it is basically an abbreviation for lossless compression…
Raw = all data there as captured
Lossless compression = data compressed, but full information can be reconstructed (all the way to raw)
Lossy compression = compressed and some information is lost
Why do you think I stressed "But a static screen of some 20 seconds,…" in my previous post? When the screen is static it can easily be compressed losslessly by an incredible amount. It is logical, right? The video codec just says this is the screen, repeat it x times…
I actually increased the recording bandwidth from High (50Mbps) that I was using previously to the absolute nvidia max of 130 Mbps and just recorded a blank white screen FHD on a good system where I saw almost no changes and the size in MP4 was just 1MB (yes, one megabyte)! But again, it is logical as it is an all white screen and there are no changes - and it's a proof it must be lossless as it never even remotely approached the limit of 130Mbps (=16.25MB/s).
Frankly I believe the fact that a static game menu screen for 20 secs that I presented above produced a 50MB file is a result of having those tiny changes that I detected! If it was really static as it should be it could probably never reach that size.
