but again, you seem to be doing this to prove a point rather than its how a normal person would use it.
And from my testing (i'm currently on the other side of the world from my server) it takes no longer to start a file that is 29Gb in size from time =0 than it does to start the same movies from the middle using a chapter or resume marker. so i don't really understand the point
well then with all due respect you must be old or sitting a long way from your tv. a) it stands to reason that of course quality is reduced when the file size is reduced, its not packed with air i can tell you from my own testing that i have never seen a conversion that i have been truly happy with in terms of quality. the drop may vary from very slight to quite significant but i've never had a conversion i've been 100% happy with. I tried to do exactly what you are doing last year, couldnt find a way of converting that i was happy with. thought about it for a while and decided that given we are headed to larger and larger screens there was just no point in converting given the cheapness of HD space, the cost of conversion (if you have one of those smart plugs that can report power usage its very interesting to watch how much more is consumed by the cpu running at 100% for extended periods of time is, i did this) and the loss of quality on conversion
Not as old as you might think, but I do know a few things about encryption and compression along with file formats. Not exactly a guru when it comes to video and audio. However i do know especially in the computing world there are many ways to represent data, some take far less room than others. Then there is also the human limitation. Fact is when talking 1080 most people wont notice a pixel or 5 that are out of place, dead or incorrect there has to be pretty large problems for someone to notice unless someone is staring and looking for an issue at the screen and there is no real motion or change of scenary. I suspect your notice of quality is likely the placebo effect, or bad configuration. The science behind all this basically says you have to be far closer than what most people are to get un-noticable quality differance. Scroll down to the bottom to see the chart: https://www.forbes.c...v/#34752dd24db7 if you have a 75 inch 4k tv you need to be under 5 feet from it to get full benefit. I doubt anyone with a tv that big sits that close hell would the whole tv even be in your field of vision?
