how to use ffmpeg to trim videos

The video editing applications may be extremely useful, allowing you to trim videos while on the move using your phone or tablet. Whether you're a professional video editor, YouTuber, or simply want to edit personal videos to publish on social media, this might be a highly convenient and cost-effective solution.

And after spending countless hours experimenting with the finest video editing apps, we can promise you that many of them are often easier to use than desktop software due to their simplified interfaces and fewer capabilities. While it does imply that they have some limits, it also means that they are ideal for short tweaks or for novices and casual users who don't want to spend a lot of time learning more complicated applications. Therefore, we will introduce you a great video editing software to trim video, which is called FFmpeg.

Part 1: What is FFmpeg?

FFmpeg is an abbreviation for Fast Forward Moving Picture Experts Group. It is a free and open-source software project that provides a variety of video and audio processing features. It's intended to be operated via a command-line interface, and it includes a plethora of libraries and tools for manipulating and handling video files. One of the reasons FFMPEG is so popular is that it includes codecs for encoding and/or decoding most audio and video file formats, allowing it to be used for transcoding many types of media files into a single standard format.

Part 2: How to Use FFMPEG to Cut Video

2.1 How to Use FFMPEG to Cut Video by Time

It is quite simple to use FFmpeg to cut video. The video clip can be shortened once the start and end points are determined. To trim a video, FFmpeg provides relatively easy command-line options. Please follow the steps about how to cut video with FFmpeg below.

how to use ffmpeg to trim video by time

You must enter the following command:

FFmpeg I input.mp4 –ss 00:01:50 –to 00:03:16 –c copy output.mp4

-i: It is an abbreviation for the input video file. Here's the input.mp4 file that goes with it.
input.mp4: This is the name of the input video file, which you can call and name however you choose.
-ss: This specifies the beginning of the section to be trimmed.
This concrete point (start time) can be found in the input file at 00:01:40.
-to: You wish to cut the end of the section.
00:03:16: This particular point (finish time) can be found in the input file.
-c copy: This option means cutting video by stream copy, which is quick and does not require re-encoding.
output.mp4: This is the name of your output file, which you can customize.

Note: "-t" can also be seen in what someone else displays. It refers to the length of the part to be trimmed, rather than the end time.

2.2 Using FFmpeg To Cut Video By Time Without Re-Encoding

Using FFmpeg to trim video without re-encoding, you can utilize the "Copy and Input seeking" option. It's worth noting that when you use the search function, you'll notice a frame jump. As a result, it may not precisely terminate inside the time limit that you previously desired. It will locate the nearest "i-frame" to begin the copy process. Use the command line shown below.

FFmpeg -ss 00:00:02 - i inputVideo.mp4 -to 00:00:05 -c : v copy -c : a copy trim_ipseek_copy.mp4

You just told FFmpeg to trim 3 seconds from the second second and end the session at the fifth second of the video "inputVideo.mp4".
