It has nothing to do with tech. The same reason Daren shoots film is why I still shoot film, at any speeds. Since almost no one chooses to shoot true 24fps anymore, everything is sampled down and so everything I watch looks like shit. Sharp, but jittery shit.
Use the tool for the situation. I actually respect the tech behind the sphere and 18k cameras, because it's purpose built and I imagine looks lovely in its native speed and fov.
But Daren... this piece is gross man.
- crazygringo 3y agoYou still haven't defined what "true 24fps" is, and the idea that it "has nothing to do with tech" makes no sense. 24 fps is a technical term, no more and no less. And everyone here is left baffled because it seems to be some personal notion of yours, as opposed to what it is universally and clearly understood to mean. I literally have no idea what you mean when you talk about things being "sampled down" or "sharp, jittery shit". The only thing sampled down in most modern TV/film production is a usually a 4K source down into 1080p or less for distribution. But I can't possibly imagine you're objecting to that. And frame rates aren't "sampled down". Meanwhile, by "jittery" I can only guess you mean shutter speed, not frame rate? Normal shutter angle is 180°, and that has been standard for many, many decades, identical between film and digital, and which has never been jittery. Sometimes action scenes use a smaller angle (faster speed), which you're free to call jittery, but that's not the norm. Generally just for action scenes, or for occasional other artistic effect. If you want to have any kind of productive conversation on HN, I suggest you start explaining what you actually mean rather than throwing around terms with idiosyncratic personal definitions you simply invent, that have nothing to do with how the terms are generally understood.
- clnq 3y agoI never thought about this, but what if you shoot at 30 fps and want to produce 24? How do you map 30 onto 24 time-wise? In 30, each frame lasts 33.33ms. In 24 it’s 41.66. So if the first frame is synced, the second frame of something captured in 30 and transformed to 24 would show up 8.3ms too late. The third - 16.ms, and so on. It’s not possible to properly sync video to 24fps if it was shot at 30 without interpolation, right?
- Kirby64 3y agoIt’s commonly done the other way, actually. Converting 24fps to 30fps for converting film (typically shot at 24fps) to TV broadcast ready, which is 29.97 fps in the US/NTSC region. That said, you can go the other way. Basically, you interlace certain frames. Wikipedia has a great article on this. https://en.m.wikipedia.org/wiki/Three-two_pull_down#2:3 https://en.m.wikipedia.org/wiki/Three-two_pull_down#2:3
- clnq 3y agoThanks. Then I suppose it doesn't matter if it's 30fps to 24fps or the other way around, the process is probably similar - either interpolation or interlacing. And that brings up an interesting point - after such a process, is it possible to produce clear visuals on each frame? The image [0] on the Wikipedia article illustrates my question.
