Answer this question .... Std US TV FPS

[George Butterfield]

Who's the idiot who runs the Cinematography.com website? Answer this question .... "Std US TV FPS". That is the question you have to answer to register. Why have a question which has several possible correct answers which will not allow registration? What is the phraseology he wants, not that I care, anymore. I wonder if he wonders why the website has so few subscribers.

I can only think of one answer, so I would perhaps consider shifting the blame away from the owner of the site. Also, consider not going into a rant immediately when something is wrong. You can always research the question or ask someone else. Getting angry at the person who runs the site will accomplish very little.

[George Butterfield]

I can only think of one answerAnd that is? Seriously, FPS could be Frames per second or it could be Fields per second, the "correct" answers could be 29.97 or 30 or 60 or 59.94 or Thirty or Sixty .... I tried them all .... As a matter of fact Andy, you're starting to bug me.

no no, I think you might be looking too far into it. It is asking the standard...the standard in US is 29.97. Yes you can use 59.94 and 60, but the standard is 29.97. And fields per second...isnt that a PAL thing? US is NTSC, so it is irrelevant. So it actually is a decent question. Anyone do chime in if I am incorrect.

It 30*(1000/1001)=29.97002997fps

Be sure to post the answer here that works!?

[George Butterfield]

It 30*(1000/1001)=29.97002997fps

Be sure to post the answer here that works!?I've gotten tired of trying ... each failure requires me to type in the "bot deterrent", phrase also .... I was next trying to download an ARRI 16mm manual from the ARRI site and they required a password .... I've told the Producer it's a RED or count me out.

I just tried with a throwaway and 29.97 worked fine.

And remember with ReCapcha, it doesn't validate the second (crazier) word.

I would try with a different browser or even machine and see if the problem still persists.

EDIT: If you'd like, you can send us the link of what you need here and someone else can download and re-host for you privately.

Thanks Andy, U da MAN!

I just tried it now. It will not accept "30"
The “correct” answer is 29.97

But of course, that is NOT correct!
A more accurate answer would be 29.97002997002997002997002997003, but that is only an approximation to 32 decimal places.
The correct answer can only be:
4,500,000 ÷ 150150
Which sadly, is an irrational number.

This figure is derived as follows:

Dividing the 4.5MHz NTSC Sound carrier frequency by 296 gives the NTSC color line frequency:
4,500,000 ÷ 286 = 15,734.265734265734265734265734266

You then multiply that by two, and divide that figure by the number of lines per frame (525), to give the NTSC field frequency:
15,734.265734265734265734265734266 x 2 = 31,468.531468531468531468531468531
31,468.531468531468531468531468531 ÷ 525 = 59.940059940059940059940059940059

You then further divide that by two to give the frame frequency:
59.940059940059940059940059940059 ÷ 2 = 29.97002997002997002997002997003 (but only accurate to 32 decimal places)

If you wanted to be pedantic you could calculate the film frame rate for color TV as follows:

Divide the color TV frame rate (29.97002997002997002997002997003) by the monochrome frame rate (30):
29.97002997002997002997002997003 ÷ 30 = 0.99900099900099900099900099900098

Then multiply the monochrome film frame rate (24) by that figure to give the color film rate
24 x 0.99900099900099900099900099900098 = 23.976023976023976023976023976024

But only if you wanted to be pedantic :emote_couch:

No, both NTSC and PAL have fields.
The two systems are very similar in principle, just the numbers are different.

And of course field dominance. Upper and lower. Unless you're talking DV, which has field dominance set as NTSC. But it's been that long since I did anything in SD, I now forget which is which :smile5:

31,468.531468531468531468531468531 ÷ 525 = 59.940059940059940059940059940059

Ha...T-shirts would be hilarious...starting large at the top with: "The “correct” answer is 29.97" (and then progressively getting smaller and smaller as it flows to the bottom of the shirt.)

After many years, I only just discovered that the calculator that comes with Windows can be set to "Scientific" mode with 32 decimal places. Makes it easy to paste the results into forum posts!

[Victor Lazaro]

+1
I still think there are a lot of other questions they could have used instead of this one. I got stuck and had to google the answer (wrote 30, then 60 the google)

[Gavin Greenwalt]

TV is 29.97, not sure what the drama is. As to it being a stupid question, film fps would have been a better question. Also I'm not sure I've ever seen "fps" refer to "fields per second".

Steam though takes the cake. I had to reset my password this week and it asked "What school are you going to?"

Now *THAT* question is a terrible security question. "Ummm, what year did I answer that for? And how exactly did I write out my school's name? Did I use achronyms? Did I write out the full name or just the general shortened phrase? Was I in college? Gradeschool? Highschool?" There's probably 2 dozen possible answers to that question.

Life???

It's an interlacing thing...

15,734.265734265734265734265734266 x 2 = 31,468.531468531468531468531468531
31,468.531468531468531468531468531 ÷ 525 = 59.940059940059940059940059940059

Yes pedantic. Seriously this is pure slap back to film school. Nice.
