Uploading to web at 25fps?
.

True, this is the unlucky part of living in PAL land. If the Web is your target, consider shooting 50i (not 25p), deinterlace down to 30p then check motion restitution on your computer before uploading. The new YouTube HD is significantly better than Vimeo which is plagued by frame rate throttling and image freezes.

Thanks Stephan.
I've been told that Vimeo supports a maximum of 24fps for HD videos. Seems odd to me. Uploading 30fps video at HD resolutions apparently results in choppy motion, as would 25fps. I must now own up. I've posted this question elsewhere, and gotten a brilliant reply, which I should share: Uploading 25fps to the web..? - Cinematography.com Community of Film and Video Production Professionals Man, I love the web! |
That response over there is great, maybe a bit overly complicated though. Before you run into clock skew problems and hand-code your own player (better than that of the PS3?) you will need to manage the frame rate conversion and will also run into the codec issues which weren't mentioned (like bandwidth starvation). Or said differently, don't worry about phase-lock loops, you should be reasonably fine with YouTube.

Can you translate that into English please...?
No really, I don't expect you to. Have a good festive season! |

It's completely possible that there is some truth to your statement. However I don't know if there are many of us on the planet with eyes good enough to notice the difference. |
Cheers!
I could devise a shot that would show up any irregularities of that sort to the eagle eyed, but in the real world it's not going to show. |

As for Vimeo I also heard about the 24fps limitation being lifted, but never was able to find the right settings or codec combination. Always had the horrid 1Hz frame jump. |
Not just cultural - Americans might be interested to note that we in PAL countries will often observe flicker on a 30fps tube TV until we get used to it - but also age. I used to see fluorescent lights flickering out of the corner of my eye until I was about 16, and right up to my mid-twenties a big colour TV set would drive me out of the room because of the high pitched whistle.
Presumably a very small child sees virtually our whole world flickering around it: TVs, lights, clock displays, LEDs. Gawd knows what a cat or dog sees... Try turning a CRT upside down (or stand on your head). You may be surprised that you can see the flicker. Out of the corner of your eye (which is more sensitive to change so you're not caught out by any predators creeping up on you) you most likely will. p.s. Vimeo say they're about to introduce 25p HD. |
