FFmpeg to trim, pause and speed up
4 septembre 2020, par João AbrantesI have a single video and I want to transform it in the following way :


From the beginning of the video until the
end_of_part_1
I want the video to be at 1x speed.
Then I want the frame of the video atend_of_part_1
to be rendered for one second (with silent audio).
From the next frame to theend_of_part_2
I want the video to be played at 2x speed.
From the frame afterend_of_part_2
to the end I want the video to be played at 1x.

What is the best way to achieve this with
FFmpeg
?
