![]() Since our audio file will be MP3, which can be handled by an MP4 container, you can omit the -c:a option. Then, we specify the video codec ( -c:v) to be copy to tell FFmpeg to copy the video's bitstream directly to the output with zero quality changes, and we specify the audio codec ( -c:a) to be aac (for Advanced Audio Coding) to tell FFmpeg to encode the audio to an MP4-friendly format. To do this, you must provide the video file and stock background music file as input files for ffmpeg. Suppose you wanted to merge the audio of a video with stock background music to fill the silence. Merging Background Music with a Video Clip's Audio # ![]() Note: If the input video files are encoded differently or are not of the same format, then you must re-encode all of the video files with the same codec before concatenating them. It starts with the Big Buck Bunny video, and then immediately jumps to the Jellyfish video at the 10 second mark. When you play the concatenated.mp4 video file, you will notice that this video's duration is 20 seconds. If you are just concatenating files referenced via relative paths, then you can omit this option. Note: Setting the -safe option to 0 allows the demuxer to accept any file, regardless of protocol specification. By omitting the decoding and encoding steps for the streams (via -c copy), the command quickly concatenates the files with no loss in quality. Essentially, this command concatenates audio to audio, video to video, subtitles to subtitles, etc., and then combines these concatenations together into a single video file. Since both video files are both MP4s and encoded with the same codec and parameters (e.g., dimensions and time base), they can be concatenated by passing them through a demuxer, which extracts a list of video files from an input text file and demultiplexes the individual streams (e.g., audio, video and subtitles) of each video files, and then multiplexing the constituent streams into a coherent stream. If the command is already installed, then the terminal prints a synopsis of ffmpeg. To check, simply type ffmpeg into the terminal. Some operating systems already have ffmpeg installed. How to merge the audio of a video clip with stock background music. This either significantly reduces or completely eliminates your dependence on a user interface to manually perform these tasks by moving around items, clicking buttons, etc. With ffmpeg, Bash scripts can automate your workflow with simple, single-line commands, whether it is making montages, replacing a video's audio with stock background music or streamlining bulk uploads. ![]() Commonly, developers use FFmpeg via the ffmpeg CLI tool, but there are language-specific bindings written for FFmpeg to import it as a package/dependency into your project/s. FFmpeg is a cross-platform, open-source library for processing multimedia content (e.g., videos, images and audio files) and converting between different video formats (i.e., MP4 to WebM). Fortunately, you can develop a partially autonomous workflow for video editing by offloading certain tedious tasks to FFmpeg. If you produce lots of content weekly for a platform, such as YouTube, and work on a tight schedule that leaves no extra time for video editing, then you may consider hiring a devoted video editor to handle the video editing for you. For example, in Adobe Premiere, to manually concatenate footage together, you create a nested sequence, which involves several steps of creating sequences and dragging and dropping clips into a workspace's timeline. Such software features many tools to unleash the creativity of its users, but each comes with its own set of entry barriers (learning curve and pricing) and unique workflows for editing tasks. To process and polish video and audio files, both professionals and amateurs automatically resort to using interactive software, such as Adobe Premiere. These platforms rely on content creators to upload, share and promote their videos and music. Online streaming and multimedia content platforms garner a large audience and consume a disproportionate amount of bandwidth compared to other types of platforms.
