What Factor Limits Image Frame Rate

What is the maximum FPS (Frames per second) attainable on a PC?

Theoretically, there can be an unlimited amount of frames attained on a PC. The limitation would be based on how fast your graphics processor can create those frames to display. So if you had the fastest GPU in the universe (maybe its powered by a star), then that GPU could produce an astonishing amount of FPS. The more immediate limitation (well not really a limit) is the refresh rate of your monitor. The standard is 60 FPS but you can reach higher with rates at 120 and 144 hz. (Hertz is another way to describe rates) I’m not sure what the highest refresh rate for a monitor is, I believe it’s 144 hz.Now you might be thinking that having frames higher than the refresh rate of your monitor is pointless because your monitor is the “bottleneck.” In truth, this is not really the case. Even though you may be getting 200 fps but only have a 60 hz monitor, your experience will still feel smoother because your monitor is displaying the most recent frame. When your GPU is processing frames at such a fast rate, your monitor can choose the most updated frame to display, resulting in a less jagged or lag experience when frames do slow down. Hopefully the following image can help describe this process.

Why do videos get dimmer at higher frame-rates?

OPOQ:Why do videos get dimmer at higher frame-rates?The amount of light hitting the sensor and creating the image is shortened. Therefore the image will get darker, it is similar to using a faster shutter speed without compensating with opening the aperture or increasing the ISO setting on a stills camera . The problem s with video that the high frame rate basically operates like a high speed shutter that you cannot change.,There are a number of ways to avoid this, though that depends on the frame rate involved, if it is very high then it maybe impossible to compensate correctly due to the limitations of the various variables. For example the ISO rating for the camera may not go high enough on that particular camera, or the lens may no be fast enough to achieve a wide enough aperture.So the easiest way is to use more light on the subject. Shooting outside in the sun is probably the easiest way to remedy this problem.However, a completely different approach for very high speed photography and videos is using flashing strobe lights, but that is a whole different ball game.

Does time travel at the speed of light?

If we are living on planet earth then we are living in the "now." Hypothetical example:
You have a device that creates a wormhole between planet earth and planet X
On earth you look at the time/calendar and it is Jan 1st 2010.
You go through the wormhole to planet X.
On planet X you look at the time/calendar and it is Jan 1st 2310. (different calendar and different time reference)
You look through a Huge telescope at planet earth, and you see the events that are "currently" taking place Jan 1st 2000 on planet earth. (time travel)
You go through the wormhole back to planet earth.
You look through a Huge telescope at planet X, and you see the events that are "currently" taking place Jan 1st 2300 on planet X.

You go into a spaceship and travel to planet X at the speed of light.
When you arrive at planet X, the watch on your wrist (earth watch) shows Jan 1st 2010, but the calendar on planet X shows Jan 1st 2320.

What is the maximum video file size to upload on Facebook?

Keep in mind that videos must be less than 45 minutes long and smaller than 1.75 GB. The longer your video is, the larger its file size will be. This may affect the quality of the video.Facebook Video in High QualityH.264 video with AAC audio in MOV or MP4 formatAn aspect ratio no larger than 1280px wide and divisible by 16pxA frame rate at, or below, 30fpsStereo audio with a sample rate of 44,100hzUpload 4K Videos to YouTube/Facebook/Vimeo maybe do you a favor.

Why can't a video camera usually record at the same resolution if it increases the frame rate?

Sham’s earlier answer is basically correct. But to add some more detail:Various parts of a camera system have different limits. Depending on how the camera is configured, various combinations of image size and frame rate may be available. In some modes, you may hit the maximum data rate of the connection to the outside world, or the maximum A/D conversion rate, or the maximum rate that (analog) pixels may be read from the sensor.One particular sensor that I am familiar with has a 16-bit bus for connection to the outside world, and you need to use all 16 bits for maximum performance. If you need less than maximum performance, and want to reduce cost, you can choose to use only 8 or 4 bits of that bus. This reduces the maximum data rate by a factor of 2 or 4.The A/D converter is 12 bits wide, but 12-bit conversion takes longer. By reducing the pixel size to 10 or 8 bits, you can get more pixels/second, giving you either a higher frame rate or larger image.Actually receiving the data from this sensor at maximum clock rate takes a fairly powerful (and power-hungry) FPGA. If you don’t need maximum performance, you can reduce the clock rate.Finally, you might voluntarily choose to reduce the frame rate or the image size below the maximum the camera is capable of simply to get more recording time on a finite-sized storage device.Dave
