This has been a bugbear of mine since the last days of mini-dv tape, you see the problem no one has paid any attention to...What has happened is that in 2018 we are right back in the early days of film, the medium on which we "save" the video image at point of capture is limited, unlike mini-dv tape that was cheap and lasted a long time, that is you could shoot 60 minutes and then in seconds,eject and carry on, sure the process of getting the material into the computer was slow, 1 to 1...
So someone had the idea that something faster than 1:1, would be better, which for news makes sense, but for other forms, not so much, maybe bridezilla's you need faster than 1:1:, like have the edited version done before the wedding...
Now we are screwed royally, we have RED that you can only record a couple of minutes per card, and then that takes an age to transfer, all in the name of video quality..which is important...what is important?? Image quality or transfer time???
Look codecs will change, pro res will be different in 6 months time, maybe.. Keeping multiple copies of source material will be very expensive if it is not going to reused again, what do you do? With mini-dv tapes, you basically only used the tape twice, once to record onto, and a 2nd to digitize...so you did not have to worry about too much tape use...
I don't have an answer, other than I hope one day someone wakes up and sees the iceberg ahead..I see it and all I see is disaster ahead...We as a industry are fast asleep...
