If you want the input and output frame rates to be the same, then just declare an input -framerate and the output will inherit the same value.īy using a separate frame rate for the input and output you can control the duration at which each input is displayed and tell ffmpeg the frame rate you want for the output file.
The output frame rate for the video stream by setting -r after -i or by using the fps filter.The default for reading input is -framerate 25 which will be set if no -framerate is specified. The rate according to which the images are read, by setting -framerate before -i.Important: All images in a series need to be the same size and format.
