Fastest way to automatically split video into shorter segments

How do I split a video into X parts, each duration is X minutes?

If you are not intimidated by the command line, you can use ffmpeg like so:

ffmpeg -i 'input.mp4' -map 0 -codec copy -f segment -segment_time 10:00 'output%03d.mp4'

The options are as follows:

-i ‘something.mp4’ → the name of the input file
-map 0 → use the first input file for all outputs
-c copy – copy theaudio and video as it is in the place where they present
-codec copy → do not recompress the video
-f segment → the output file will be multiple segments
-segment_time 10:00 → create segments of this duration (10 minutes in the example)
‘output%03d.mp4’ → name the output files like output001.mp4 etc. (3 is the number of digits in the counter)

For example if you are going to split the Video having the file name single1.mp4 to multiple files of duraction 12 seconds with the file names split1 suffix with 3 digits starts with 001. below is the command to be used

ffmpeg -i "single1.mp4" -c copy -map 0 -segment_time 00:00:12 -f segment -reset_timestamps 1 split1%03d.mp4
