Cutting multimedia files based on start and end time using ffmpeg

The fastest and best ffmpeg-based method I have figured out is:

ffmpeg -ss 00:01:00 -to 00:02:00 -i input.mp4 -c copy output.mp4

This command trims your video in seconds!

Explanation of the command:

Command Explanation
-i This specifies the input file. In that case, it is (input.mp4).
-ss Used with -i, this seeks in the input file (input.mp4) to position.
00:01:00 This is the time your trimmed video will start with.
-to This specifies duration from start (00:01:00) to end (00:02:00).
00:02:00 This is the time your trimmed video will end with.
-c copy This is an option to trim via stream copy. (NB: Very fast)

The timing format is hh:mm:ss.

Please note that the previous highly upvoted answer forces a reencode, and so the trim would be extremely slow. For more information, look at this official ffmpeg article.
