• encoding jpeg sequence with ffmpeg

  2 août 2022, par Frog person

  I do not have much expertise. I have been trying to convert a 240 jpeg long sequence (in a folder named plane) in to a 24fps mp4 file. each file is named 0001.jpeg , 0002.jpeg and so on.
I have tried this
ffmpeg -framerate 24 -i C :\Desktop\plane\image%4d.jpg output.mp4 and some variations on that but nothing seems to work.

  


  the above command results in this
