Suggestion For Fox Sports

love the drone shots. keep em' coming. love the extended shots too, usually into and out of commercial breaks.
one showed the strip with sphere. one panned over towards nascar track ...... and something i see every year at vegas.
nobody gets more mileage than toyota does with the billboard along the interstate that lines up perfectly off the end
of the dragstrip.

She is on maternity leave…

Being that I watch all the races on .TV that was pretty obvious.

i think Courtney does a very good job. Maybe i like her because she's a prostock fan (for obvious reasons) as am i, but she displays a genuine passion and knowledge for the entire sport.

Why is the finish line stop action shot always 3 feet BEFORE the stripe? This was better 10 years ago... didn't the cameras improve since then?

All video cameras have a frame rate and for sports action most are 120 frames per second. The video is actually a series of still shots - in this example 120 of them per second - and when replayed the stream of still shots happens so fast that it is mistaken by the human eye as continuous movement. Considering that 300 mph is 440 feet per second, divided by the frame rate of 120, is 3.6 feet. So if they capture the still shot one frame later it would be past the finish line. The reason for the blur and apparent leaning back of the car's front end is because the camera starts at the upper left and by the time it reaches the lower right 1/120 of a second has elapsed and the car has moved farther downtrack.

There are 240 fps cameras, which would cut the distance in half and remove some of the "lean."

David, do you have an idea of the amount of time the camera is actually capturing the image?

For example, 120 frames per second, but how much of that 1/120th of a second is the camera actually capturing the image?

Isn't there a small period of time within that 1/120th of a second when the camera changes from frame to frame that is not captured (somewhere between a unit of Planck time and 1/120th of a second, and much, much, much closer to 1/120th of a second than a unit of Planck time, which probably cannot be measured)?

just pulled up a youtube race from 1990. the finish line shot stops directly at the finish line.
could be older camera technology easier to do this? one thing i noticed was the camera was at 1320', so as the cars
traveled downtrack, the finish line was a direct 90 degree turn. i think we all remember these finish line shots.
....... interesting (david parsons) reading about today's digital video cameras.
