Sorry, but that's not what you'd expect. Or if it is, you can't have watched many Liverpool matches last season.But that would defeat the purpose of VAR. At a level that VAR is used, you would expect AR's to get the ones that are not tight right pretty much every time. Its the tight ones we need VAR for and to revert that back to the AR...
jpeg itself is compress so there is a loss of quality there.The technology used by VAR was first intended for use elsewhere (horse racing believe it or not) and was co-developed by colleagues of mine. It's 50fps and it's uncompressed which means it's all i frames (like 50 jpegs at 50Hz). I'm a network Engineer, as opposed to a Broadcast equivalent, so don't ask me to cite great technical knowledge of the system, but the above statement is fact. Maybe I'll ask some more questions on returning to the office next week
