I am merging an image sequence into a video using the following command:

ffmpeg -f image2 -i "input\image%09d.png" -framerate 60 output.mp4

However, the framerate of the output video is always 25, no matter what I
set as -framerate argument. What is going on?

-framerate is an input parameter which must be written before the input file. For the output framerate you can use the -r parameter. These two framerates can be different, FFmpeg will automatically skip or duplicate frames.

ffmpeg -f image2 -framerate 20 -i "input\image%09d.png" -r 60 output.mp4
