I thought there would have just been:
a) World Feed footage
b) Onboard Feed footage
c) Broadcasters' footage (ie BBC pre-race and post-race stuff filmed on location)
However, reading this: http://www.f1fanatic...g-senna-part-5/
In particular:
“It sounds a bit nerdy, but we always tried to find the angle that hadn’t been broadcast.”
Am I right in saying that literally everything from every single camera is kept at FOM? So, I don't know let's say there's 30 cameras for Monaco (there's probably more, but for argument sake) which records:
Thursday - 08:00 to 18:30 (10 hours, 30 minutes)
Friday - 09:00 to 13:00 (4 hours)
Saturday - 08:30 to 17:30 (9 hours)
Sunday - 09:00 to 17:00 (10 hours)
So for just one camera you have 33.5 hours of footage.
Now, multiply that by about 30 cameras and you get 1,005 hours of footage for a race weekend!

That just seems, incredible really. I'd love to know just how many hours of footage are in FOM at Biggin Hill, you must surely be going into at least half a million hours, surely?
