• how to prevent FFMPEG from increasing the video size ?

  28 juin 2018, par drexdelta

  My aim is to compress the video and reduce its file size.

  ffmpeg -i input.mp4 -crf 28 output.mp4

  Now, this command, increases the size of the given input file. And on the otherside, quality of the video is same as earlier. So, it’s increasing the space for nothing.

  How can I stop this from happening .

  This is original video (size 9.5 MB) , and this is the compressed video (size 13.2 MB) .

  So, I want to know, if it is possible to detect using ffmpeg, whether the size of the final video will increase or not ?

  FYI : I am writing script. I am not planning to change the CRF factor. Because that will damage quality of other good videos.

  These are the details on my ffmpeg version :
