Questions tagged [fps]

FPS is short for "frames per second" and is often a measurement unit of rendering performance.

The FPS is a value that describes how many individual images a certain device can display within a single second.

Higher values are usually more desirable as they result in a smoother image display.

Interpolation with FFmpeg

Is there a way to interpolate frames with ffmpeg? and not just copy them. I tried slowmovideo and boy it is slow. I used Twixtor in vegas and hated it. I gave megui and could not get it properly set up. So is there a way to interpolate with ffmpeg??

Why does windows cursor not move at 60fps?

Why is it that when I move my mouse rapidly in circles I can see multiple versions of it? This looks like a frame rate problem. My computer is plenty powerful enough to render the pointer at 60fps but it does not. This is especially pronounced when…

How to convert 1080@50i -> 720@50p using ffmpeg?

I really like 50fps video, but I cannot make ffmpeg convert it to 50fps for me. 720p resolution is absolutely fine with me, just need more FPS. 50i just looks much smoother in proper players (for example GOM Player deinterlaces video and plays it at…

Video encoding: How much does the video file size increase with fps?

Given that the next blockbusters of e.g. Peter Jackson (The Hobbit) and James Cameron (Avatar 2) are going to be shot with a frame rate of 48 fps (or even more) - i.e. more than the usual 24 fps - I was wondering: How much does the file size of the…

Does it make sense having FPS higher than the monitor refresh rate?

I've heard that the human eye processes twenty-four images per second. Also, monitors usually work with 60Hz. My question is, for a highly interactive application (e.g., a fast-paced FPS game) does it make sense to render faster than the monitor…

Can someone explain to me the correlation between bit rate and frame rate?

I understand the higher the FPS, the smoother the image will look at your current resolution. This also corresponds to refresh rate over the monitor. Your FPS can only go as high as your refresh rate 60hz 120 hz, etc until you get weird effects. (If…

This has been bugging me for a while. Every once in a while, I find my computer to be sort of laggy and I thought it was because it was busy or something. However, I recently noticed that it wasn't any performance issue...I thought my computer was…
