Let me tell you about concatenation and splicing of video using ffmpeg.įor splicing of video we'll use following command:

There are various usage of this tool in video domain except Cancatenation and Splicing of video. This programme is completely written in C language, due to this feature it's somewhat CPU intensive but extremly fast and durable in context for video manipulation and transcoding. It's available in all OS variant binaries. Mostly transcoding based and platforms uses ffmpeg as core solution for video modification and manipulation. We'll learn about some of ffmpeg tricks for video splicing and concatenation, first of all I want to let you know about FFmpegįFmpeg is a most usable tool for video editing world-wide either it is directly used or using various application. Since this involves compressing the file, it will take (much longer) than the first method.Video Splicing and Concatination using FFmpeg h264 video and aac audio compression: ffmpeg -i input1.mp4 -i input2.avi -c copy -map 1:v:0 -map 0:a:0 -shortest -c:v mpeg4 -c:a aac output.mp4 If you want to convert (and compress) the file in one operation, you can use this one-liner to export an MP4 file with. Note that this is a lossless (and fast) procedure, it will just copy the content from the source files.

The output.avi file will have the same video content as input2.avi, but with audio from input1.mp4. Then you can use this one-liner to copy the audio from one file to the other: ffmpeg -i input1.mp4 -i input2.avi -c copy -map 1:v:0 -map 0:a:0 -shortest output.avi

input2.avi = analysis video without audio.

A better solution is to use FFmpeg, the swizz-army knife of video processing.Īs long as you know that the audio and video files you want to combine are the same duration, this is an easy task.

Many people would probably reach for a video editor, but the problem is that you would most likely end up recompressing both the audio and video file. So I need to add the audio track by copying either from the source video file or from a separate audio file. When working with various types of video analysis, I often end up with video files without audio.
