The below video tutorial explains in detail with step by step process of adding multiple audio tracks to a single video and this way you can add more audio files into a video file on your own.
Adding Multiple Audio tracks to single video using FFMPEG: So Adding multiple audio tracks will help us to reduce storage size About FFMPEG:įFmpeg is a free and open-source project consisting of powerful audio and video converter software suite of libraries and programs for handling video, audio, and other multimedia files and streams. Your audience might be from various demographics and you need to plan the audio tracks accordingly so that everyone would understand the video better.Īlso let us say, in case your family/friends are comfortable or only understand their particular language, then we need to store individual video for every single audio file this will cost your storage size i.e language count * video storage (4 * 1.5GB = 6GB). In this fast-paced world, we must agree the fact most of us spending money like buying a tool or software even for small things that we can do it by ourselves just by writing a one-line command.īefore digging deeper into the details, let’s just give a thought about why we should go for multiple audio tracks and how does this help? Why go for multiple audio tracks?Ĭonsider this, you have created a video and planning to run it for a presentation or upload it online for everyone to watch. This will reduce the size of the new MP3, but may sacrifice some quality.įfmpeg -i video.mkv -q:a 0 -map a audio.In this article, I’m going to help you learn how to add multiple audio tracks to a single video file using FFmpeg tool. This command creates a variable bit rate (VBR) MP3 instead of the CBR file as in the above example. Convert audio track to variable bit rate MP3 (VBR) In this command we specify the that the bit rate of the new audio file will be a constant 192kb/s (CBR).
FFmpeg will re-encode the audio track so you can also specify some additional quality options.įfmpeg -i video.mkv -b:a 192K -vn audio.mp3 right click clip on second track and select unlink. for the duplicated entry, right click and select properties (or click the gear) - there activate the second audio track. This example assumes that the video’s audio track is something other than MP3 (or whatever target format you want). heres a workaround: - in the media browser, right click Media entry and select duplicate. will take first 4 audio tracks in that mxf and copy them to some new wav files.
This example assumes that the video’s audio track is already an MP3 so can be simply copied over without re-encoding.įfmpeg - i video.mkv -acodec copy audio.mp3 Convert audio track to MP3 (CBR): ffmpeg -i input.mxf -map 0:a:0 -c copy /output/a1.wav -map 0:a:1 -c copy /output/a2.wav -map 0:a:2 -c copy /output/a3.wav -map 0:a:3 -c copy /output/a4.wav. FFmpeg can easily be used to extract the audio tracks from virtually all video files and save them to new audio files: Copy audio track from video file:
