hello
thanks for your answer

I found one of these because what you posted was unfortunately not good, 
but it helped me find the one below, and I realize that with the setup 
you read here it will be fine.

< 
https://community.antmedia.io/topic/1532-youtube-saying-please-use-a-keyframe-frequency-of-four-seconds-or-less/ 
 >

the setup is:
ffmpeg -i input.mp4 -qscale 0 -g 2 outputFile.mp4

I use this option : -qscale 0 -g 2
must be written strictly before the output
