We can use the seek option to set a point in time to specify what we want a still image of. You can specify the point in time with a time code or a frame number. See the Video inputs section above.With FFmpeg, you can export an image of a specific point in time in the video.

You probably only need to use the -r output option.

Only works with certain demuxers (including: images, x11grab, rawvideo).

The image demuxer uses -framerate, while the output frame rate is set using -r.Frames will be duplicated or dropped to match the desired output frame rate.ffmpeg -framerate 1 -i input_%03d.png -r 25 output.mp4 The output will look like 1 fps, but will actually be a normal frame rate, such as 25 fps.Įxample: input images at 1 fps, but make the output 25 fps. So you can make ffmpeg use a different output frame rate. But most players can't play very low frame rates (about 6 fps or lower). Why? For example, you may want all images to be displayed for 1 second each (1 fps). Using a different frame rate for image inputs and video output Use the -r output option: ffmpeg -i input.mp4 -r 25 output.mp4 See Using a different frame rate for image inputs and video output below. So you do not need to set an output frame rate. The output will use the same frame rate as the input.Otherwise, ffmpeg will try to preserve color fidelity, but most players can't handle advanced chroma subsampling. -vf format=yuv420p (or the legacy alias -pix_fmt yuv420p) will ensure compatible chroma subsampling for MP4.

Example for 24 fps: ffmpeg -framerate 24 -i input_%03d.jpg -vf format=yuv420p output.mp4 You can change it with the -framerate input option. Default frame rate for image inputs is 25.
