How to process only a part of the video using FFMPEG

A famous tool to process videos is FFMPEG. I'm using FFMPEG for my final year project in order to process videos. We can specify the input video by using -i option. That will take the video and process whole video. Today I had to process only a part of the video by using ffmpeg. So this is how I did that.

fmpeg -ss 50 -t 10 -i input.mp4 [rest of the code] [output file]

The task was done by -ss and -t options. This will process only from 50S to 60S of the video,

-ss is used to seeks in this input file to position. This should be called before -i option. -t option is used to  limit the duration of data read from the input file. This also should be called before -i option.

We can use hh:mm:ss format also instead of using seconds directly.
