linux - Cutting the videos based on start and end time using ffmpeg

Question

I tried to cut the video using the start and end time of the video by using the following command

ffmpeg -ss 00:00:03 -t 00:00:08 -i movie.mp4 -acodec copy -vcodec copy -async 1 cut.mp4

By using the above command i want to cut the video from 00:00:03 to 00:00:08. But it is not cutting the video between those times instead of that it is cutting the video with first 11 seconds. can anyone help me how resolve this?

Edit 1:

I have tried to cut by using the following command which is suggested by mark4o

ffmpeg -i movie.mp4 -ss 00:00:03 -t 00:00:08 -async 1 cut.mp4

But it was shown the following error.

the encoder 'aac' is experimental but experimental codecs are not enabled

so i added the -strict -2 into the command i.e.,

ffmpeg -i movie.mp4 -ss 00:00:03 -t 00:00:08 -async 1 -strict -2 cut.mp4

Now it is working fine.

Answer 1

Try using this. It is the fastest and best ffmpeg-way I have figure it out:

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

This command trims your video in seconds!

Explanation of the command:

-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 (00:01:40) to end (00:02:12).
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Please note that the current highly upvoted answer is outdated and the trim would be extremely slow. For more information, look at this official ffmpeg article.
