If you are using ffmpeg to convert video,first make sure its installed properly on your server and running. Check ffmpeg installed or not on your server.

$ffmpeg = shell_exec('which ffmpeg')); 
$ffmpeg = shell_exec('type -P ffmpeg');

If $ffmpeg return empty then it means its not installed on your server, if its return absolute path it means installed on your server.

Then you can execute exec commond Just like below

exec("ffmpeg -i {input}.mov -vcodec h264 -acodec aac -strict -2 {output}.mp4");

-vcodec parameter to specify the encoding format to be used for the output video.

-acodec codec (input/output) Set the audio codec. This is an alias for -codec:a
