Other options already defined in previous commands.įor reversing video,first we need to divide video into segments with duration of 10 seconds or less because reverse video command for ffmpeg will not work for long duration videos unless your device has 32 GB of RAM.ġ.Divide video into segments with duration of 10 seconds or less.ģ.Concatenate reversed segmented videos in reverse order.Author: Author: Taner Şener - B4a Wrapper: Pendrush You can speed up or slow down audio with the atemto audio filter.The atempo filter is limited to using values between 0.5 and 2.0 (so it can slow it down to no less than half the original speed, and speed up to no more than double the input).To slow down the audio to half of its speed we have to use atempo value 0.5. For example, if there are two succesive frames shown at timestamps 1 and 2, and you want to slow down the video, those timestamps need to become 2 and 4, respectively.Thus, we have to multiply them by 2.0. The filter works by changing the presentation timestamp (PTS) of each video frame.To slow down your video, you have to use a multiplier greater than 1.
