How to use FFmpeg to cut videos by time:

FFmpeg uses various commands that you can use to cut your videos. And in these instructions, we will show you how to use the seeking parameter (-ss), and you can also use the other commands, like the trim filter. But in this tutorial, we will show you different methods to trim your videos.

Method 1. Cut using a duration

Here is the command that you can use to cut your video.

The commands above will take the input video, the .mp4 file. It will then cut 10 minutes from your video starting from 00:05:20. Then, your output will be from 00:05:20 - 00:15:20.

The -ss command represents the video's starting point, and the -t represents the duration from the starting point. Additionally, the -c:v copy -c:a copy commands are used to copy the original audio and video without re-encoding.

Method 2. Cut using a specific time

You can use the command below if you want to cut your videos at the exact time.

As you can see from the commands above, it uses -to to indicate the exact time you want to cut from your video. The trimmed video will start from 00:05:10 - 00:15:30, which results in a 10 to 20 seconds video. Note that the command will be an error when you specify a -to smaller than the -ss. It will also be an error if you put -ss before -i, -to because -i and -to indicate the duration of your video.

Method 3. Cut the end of your video

To cut the end of your video, you can use the other seeking command, -sseof, which cuts the last N seconds from your clip. Use the commands below to cut the end of your video.

By following the commands above, your video will result in a 10-minute video with a duration of 00:05:20 - 00:15:20. When using the seek command, you may encounter that the output files may not have the exact time and length you expect. The reason is that most of the video formats do not allow the seek command.

Method 4. Cut video with re-encoding

Removing the -c copy option from your command when trimming your video will allow you to automatically re-encode your video or audio output. However, re-encoding a video on FFmpeg compared to the other operations takes longer. We will re-encode your video on the commands below using the -accurate_seek flag. By using the -accurate_seek command, you will have a more accurate output length.

And those are the methods on how to use FFmpeg to split videos. By reading the ways above, you will have different choices on how you want to trim, cut, or split your videos. The drawback of using FFmpeg is that it is hard to operate; it is not a user-friendly tool. Therefore, if you prefer using a more straightforward tool, read the following part.
