Youtube's frame cap

[Josh Weston]

Am I right in saying that Youtube's fps limit is set at 30fps? I've always believed this, but a friend of mine is saying otherwise - can't see anything posted by Google themselves, so I'm just wondering if any of you lovely people can help answer this for me.

Regards (from Turkey, no less),

Josh.

Yup, it is indeed 30FPS. You can prove it by right clicking on a vid and pressing 'Show Video Info' and it will read 30FPS

 

[Josh Weston]

So it does!

Thankyou very much.

i always though that its just rendered that way to reduce size 0.o

Hmm well I never knew this! Learn something new every day I guess.

Some scepticise whether it's 30 or 35, but 30 is more than likely out of the two.

Doesn't Fraps work on Youtube vids? I think I remember it working but not sure, could use it to check the FPS.

why would it matter... Video is 23-25 FPS max... the human eye only sees 23

it isn't about what the human eye can "see" that is like saying 30fps in games looks like 60fps because it really doesn't it is so noticeable even on a 60hz monitor and then stepped up to 120hz @ 100fps it is less noticeable but defiantly present in a side by side situation.

Thats not really true though is it, you go and play games at 23 fps and see how it is

This made me want to find out more and it turned out to be quite hard to find good information about FPS and how the human eye perceives them. Wikipedia wasn't much help either as the section they have on it is marked as needing expert input and more information. What I did learn is that most people would definitely notice flicker at 30fps or less without motion blurring, but this does not mean you can't discern frames at over 30fps, just that as it gets above 30 you'll be increasingly less likely to notice them until it reaches the flicker fusion point. Talking about frames alternating between all black and all white, it says

the flicker fusion point, where the eyes see gray instead of flickering tends to be around 60 FPS

meaning that it would need around 60fps to not be aware of the frames. It then goes on to say that things get much more complex if you have moving objects in the scene and that the faster they move, the higher this flicker fusion point will be. More complex still is that motion blurring will lower the fps needed for smooth display.

Basically, it's definitely higher than 30fps and probably more like 60fps and above but it really depends what you are looking at and how (well) it was made.

I had no idea!

Anyway if you fancy reading it in even more detail.. and it does get quite detailed, you can find it here and here. Thanks for making me wonder!

Just checked a few youtube videos with Fraps and it is flickering between 27 - 31 fps on average.

Wrong.

The statement that "the human eye can see xx FPS" is total bullshed.

It various with every single person, personally I can notice a difference all the way up to around 70-80 mark, even on a 60Hz. Despite refresh rates and such forth, it's totally dependant on personal eye. However I have to say, if you don't notice a different from 23 FPS ~ 60 FPS, you got me shocked.
