Howcome old films are always fast paced? why dont they slow down old movies?
original movies seem fast paced because the cameras were hand-cranked at a slow speed. you can use windows media to play a movie at a slower or faster pace, however the sound will not sound as good, since the original film and sound are recorded onto the film at that defined speed. you can record the sound with sony sound forge onto your computer, then enhance it to match the slower/faster pace of the film, then re-publish the movie into one complete version, using windows movie maker. it won't be dvd quality, but it's nearly free software...
Is there any anime in existence that is animated at 24 or 30 fps?
Well, I have no idea since most animes aren't advertising the FPS rate. I'd say though, that most animes don't need any FPS rate higher than 12. If you want a high FPS anime, you'd probably need to go through action, mechas, or anything else that contains lots of explosions. If it isn't needing extra frames, than they won't add it. It's just more money out of their pockets. Well, just as an edit to your "additional details", I should point out, this isn't an First Person Shooter, or a movie. It costs them thousands upon thousands of dollars, and each frame less saves a huge bundle. Anime's can't afford too high of frame rates due to the fact, they'd lose way too much money. Movies and First Person Shooters don't need to pay extra money just to add some frames. Well, movies might, but not much.
If someone could move faster than the eye...?
The question really is -- can you move fast enough so that the eye won't perceive you. So, you don't have to move faster than the speed of light as some contributors suggest here -- only fast enough so that you're moving faster than the eye's response time. Think about a movie -- the frames are about 24 frames per second, and you can't perceive the flickering. That is for no perception of flicker -- the perception limit is maybe around 100-300 Hz depending on person and conditions. So, maybe around a few millisec. So, lets say you are staring straight ahead, and a 0.25 meter wide person runs past. If they can move that 0.25 meter in 1 millisec, then they will effectively be "invisible". Or about 250 m/s. Then, by the time your eye catches up, the person has moved aready, so there is no overlap.
If a frame of16mm of film is .75 cm in length, how fast does the film move through the high-speed camera when?
Motion pictures typically are filmed and shown at a speed of 24 frames per second, where a frame is a single photographic image in the film. In the field of high-speed photography, a motion picture camera that is able to move the film at 2.4 x10 (to the fifth power) frames per second is used. When the film is re-shown at 24 frames per second, the filmed object is seen to move very slowly. This technique is used to analyze the motion of objects, like bullets, that move too quickly to be observedby the human eye.
1080p @ 30fps and 720p @ 60fps whats the difference?
The issue is not really the frame rate and size, but the completely unrelated shutter (or exposure) speed. If you think of each frame of video as a stand alone photo (not technically accurate, but serves to explane the problem) it may help. The aperture is fixed so exposure is controlled through shutter speed. The brighter the lighting, the faster the speed. The darker the lighting, the slower the speed. This becomes video as you take more than 15-20 photos in a second. Most of the "Helmet cams" have a fixed aperture, poor lenses and a limited range of shutter speeds. They also may not be able to focus within several feet. If you point it down toward the ground you are trying to film the one single aspect in the environment that is moving the fastest in relation to the camera. Nothing the camera can do will make it better either. Even if you could "STOP" the motion blur with a shutter speed of about 1/2000 sec, by the time the next photo is taken 1/60 second later, the first scene has moved significantly and may be out of the frame. Your only shot at getting this view is a bright day and a high-speed camera, just a ballpark estimation you need about 2000 frames/second, which in turn means you need a shutter/exposure speed of less than 1/2000 second. And chances are your exposure speed is closer to 1/100th sec, with significant motion blur.
1080i60 or 1080p30? Film. What does this mean?
In "interlaced" mode, each frame only has half of the horizontal rows of pixels -- either the even numbered rows or the odd numbered rows. It takes two of these interlaced frames to redraw the entire image, since one frame draws the odd rows and the next the even rows. While this happens faster than your eye can see (producing a full frame every 1/30th of a second), scenes recorded in interlaced mode can show "smearing" because fast-moving things in the scene change between the recording of the two sets of rows, and those non-matching changes produce artifacts in the fully drawn frame. "Progressive" mode records (and draws on playback) all of the rows (they're called "scan lines") of pixels every frame. There's less smearing, and the image can look better -- particularly if there's fast moving action. Neither mode changes the number of scan lines, or the horizontal resolution. Interlaced mode is an option because earlier HDTVs couldn't draw all 1080 scan lines fast enough to do them all in one frame, so they used interlaced mode to display HD video. For the past 4-5 years, nearly all TVs capable of 1080 scan line display can do progressive mode. By the way, it's still video recording -- not "film." You're not using film in any way :) Peace.
What could explain that in some scenes of "Mad Max: Fury Road" characters have jerky movements?
The jerky movements are a deliberate effect due to a lower frame-rate. This means, that for a one-second shot, instead of 24 frames (stills) the particular shot would have much fewer frames but still run for one second. Those missing frames (stills) per second deny the smooth movement our eyes are used to in movies, hence the perception of jerky movements.As a creative choice, the movie does not have a consistent frame-rate. During the editing process, the frame rate was dropped or raised depending on the action on-screen. To quote from Wikipedia:The frame rate was also manipulated. "Something like 50 or 60 percent of the film is not running at 24 frames a second, which is the traditional frame rate," said Seale. "It'll be running below 24 frames because George, if he couldn't understand what was happening in the shot, he slowed it down until you could. Or if it was too well understood, he'd shorten it or he'd speed it up back towards 24. His manipulation of every shot in that movie is intense."[70] The Washington Post would later note that the changing frame rate gave the film an "almost cartoonishly jerky" look. [71]
I am trying to shoot a scene where a man is walking slowly while the people around him are moving fast. how can I do that?
1)Set your camera to 60fps if you normally shoot in 29.97 or 30fps. Set your camera to 48fps if you normally shoot in 24fps. This is because we want the camera to capture information at double (200%) your normal frame rate so we can slow it down in post (50% of 200% goes back to 100% frame rate; when you edit it will appear as 100% which you slow to 50%, which is saying the same thing) and have the quality of the film/information be as sharp as your other footage in the film or as sharp as the human eye is used to watching (24 or 29.97fps).(If you don't know which you usually shoot in, check your camera settings; it should say either 24 fos or 29.97fps somewhere near your aspect ratio "1920 x 1080" , etc.)2)Tell him to move very, very slowly in comparison to the people around him. Ideally the other people are moving very fast, but if the other people are walking, he may need to move really, really, sloth-level slow. This is because the people around him will also be slowed down, so to compensate and make them appear "fast" he has to move in very small increments. It's a good idea to record him doing this at different paces-- ex: once so slow that he is almost still, 2nd time increasing movement, 3rd time increasing movement even more (but still slow in comparison to the people around him), so you have flexibility in post-production in case the first shot doesnt come out at the speed that works for your film.3) While this is happening, record. Again, make sure you're in double your normal frame rate, at 48 or 60 fps.4)Bring your footage into whatever editing software you use, and reduce the speed from 100% to 50%. This is taking the 48 fps and reducing it back to 24 fps or taking 60 fps and reducing it to 29.97 (30) fps, to match what the human eye is used to seeing in film. In Adobe Premiere Pro, for example, this will be Cmd+R in Mac and Ctrl+R in Windows. Otherwise, you can Google what hotkey it is for your editing software or find it within one of the top tabs as Speed or Speed/Duration.5) Doing the above should help you get a slowed shot of your main character with the surrounding people faster. If you want the surrounding people to be extremely fast, either they must be moving really fast or the main person has to be really slow. All in all, the difference in speed between the person and the surrounding people should be a great difference.
How fast is this:Lee's striking speed from three feet with his hands down by his side reached five hundredths?
When you start asking questions, you might want to tell us which Lee you are asking about. If you are talking about Bruce Lee, he is dead now so it does not matter. If you are talking about a different Lee it still does not matter. Nothing anyone else can do will do you any good.
