The refresh rate (Hz) of your monitor does not affect the frame rate (FPS) your GPU will be outputting. If your FPS is higher than your refresh rate, your display will not be able to display all of the frames your computer is producing. So although the refresh rate doesn’t technically limit the frame rate, it does effectively set a cap.
A QuickCam® Pro 9000 can physically output 30 FPS at 640x480 resolution, 30 FPS at 800x600 resolution, and 15 FPS at 960x720 resolution (MJPG). For most applications, you will be limited to approximately 10 FPS (USB bandwidth limitation of 12 Mbps), unless your camera is detected as an Enhanced USB 2.0 device (480 Mbps).
There are many programs that give real time FPS. One of the more popular ones seems to be Fraps. There are also graphics card monitoring tools, such as MSI afterburner , EVGA Precision X , etc. that can display a lot of on-screen data that is related to your GPU.
By fps I don't mean the fps of the video itself, but the fps which the video player manages to display. Also the measurement of the latency would be nice to know. windows-10
The video was converted. In that case, converting between different frame rates. For example, NTSC specifies 23.97 frames per second whereas for cinematographic material, this is sped up to 24 frames per second. And then there's 25 fps and 50 fps too, depending on the release.
Show FPS has moved to the 'Rendering' tab in the developer tools sidebar. Press F12; In the bottom (console) section, click the 3 vertical dots; Select the 'Rendering' page to add it to the bottom pane; You should see 'FPS meter' 3rd item down; Update: From Chrome 80, the 'FPS Meter' checkbox is the 4th item in the list.
With v-sync enabled, the FPS are limited to the refresh rate. so when the monitor is 60Hz, you only get 60fps: When VSync is disabled, your FPS and refresh rate have no relationship to each other as such. This lets your graphics card work as fast as it wants, sending frames to the monitor as fast as it can draw them.
The -r option indicate the framerate I want. However, it's not that I want 30 FPS, it's just that otherwise it does not work correctly. Without framerate, the capture is very buggy (I guess it tries to capture too much, but can't follow). With a framerate set to 15, the output video is twice longer that the capturing duration (kind of slow motion).
With the fps filter first, ffmpeg will insert 25 duplicate frames each second in order to convert 5 fps to 30, and then speed it up 6x. With the correct order, ffmpeg compresses the stream to have 30 source frames per second, and then all the fps filter ends up doing* is change the stream metadata to 30 fps. *assuming constant frame-rate source.
ffmpeg -r 25 -i %d.jpg -vcodec mpeg4 test.avi The movie was 3 seconds long (I had 75 jpg in total). I could easily see the black picture. Then I moved to 100 fps, and I was still able to see it – but not 3 times as before (here I had 300 JPG, 3 of them were black). When I moved to 200 fps, I wasn't able to see the black JPG flicker (I 600 JPGs).
