I use this cmd below to cut a part from an MP4 video:

ffmpeg -ss 00:00:10.500 -i {$ffmpeg_mp4_vinput} -t 00:00:17.430 {$ffmpeg_mp4_voutput} 2>&1

and

ffmpeg -ss 00:00:10.500 -i {$ffmpeg_mp4_vinput} -to 00:00:17.430 {$ffmpeg_mp4_voutput} 2>&1

and

ffmpeg -ss 00:00:10.500 -i {$ffmpeg_mp4_vinput} -t 7 {$ffmpeg_mp4_voutput} 2>&1

All those cmds are called by exec() php function, they all work fine with SAME result.

Problem is when I cut a video with one of those commands, I get a video with long video from what I set in from-to in the commands. For example I get 1 second before and more than 2+ seconds after.

Is there something missed out from the commands?
