Install FFmpeg</strong></h3> <ul> <li data-xf-list-type="ul">Download FFmpeg from the official website: <a href="https://ffmpeg.org/" target="_blank">https://ffmpeg.org/</a>.</li> <li data-xf-list-type="ul">Extract the downloaded files and add the bin folder to your system's <strong>PATH</strong> environment variable so you can use FFmpeg from the command line.</li> </ul><hr /><h3><strong>2. Prepare Your Files</strong></h3> <ul> <li data-xf-list-type="ul">Place your video file (e.g., video.mp4) and audio files (e.g., audio1.mp3, audio2.mp3, etc.) in the same folder for convenience.</li> </ul><hr /><h3><strong>3. Concatenate Audio Clips</strong></h3><p>If you have multiple audio files to combine, create a text file (audio_list.txt) with the following format:</p><p></p><p></p><p></p><p>file 'audio1.mp3'</p><p>file 'audio2.mp3'</p><p>file 'audio3.mp3'</p><p></p><ul> <li data-xf-list-type="ul">Open <strong>Notepad</strong>, write the list of audio files in the above format, and save it as audio_list.txt in the same folder as your files.</li> <li data-xf-list-type="ul">Run the following command in Command Prompt (cmd) to merge the audio clips:<br /> <br /> <br /> ffmpeg -f concat -safe 0 -i audio_list.txt -c copy merged_audio.mp3<br /> This will create a single audio file called merged_audio.mp3.</li> </ul><hr /><h3><strong>4. Merge Video and Audio</strong></h3><p>Now, merge the video file (video.mp4) with the combined audio file (merged_audio.mp3):</p><p></p><ul> <li data-xf-list-type="ul">Open Command Prompt and run:<br /> <br /> <br /> ffmpeg -i video.mp4 -i merged_audio.mp3 -c:v copy -c:a aac -strict experimental output.mp4<ul> <li data-xf-list-type="ul"><strong>video.mp4</strong>: Your video file.</li> <li data-xf-list-type="ul"><strong>merged_audio.mp3</strong>: The combined audio file.</li> <li data-xf-list-type="ul"><strong>output.mp4</strong>: The final output file with the merged audio and video.</li> </ul></li> </ul><hr /><h3><strong>5. Sync Audio and Video (Optional)</strong></h3> <ul> <li data-xf-list-type="ul">If the audio is shorter than the video and you need to loop it:<br /> <br /> <br /> ffmpeg -stream_loop -1 -i merged_audio.mp3 -i video.mp4 -shortest -c:v copy -c:a aac output.mp4</li> <li data-xf-list-type="ul">If the audio is longer than the video and you want to trim it:<br /> cmd<br /> Copy code<br /> ffmpeg -i merged_audio.mp3 -i video.mp4 -filter_complex "[0:a]apad" -shortest -c:v copy output.mp4</li> </ul><hr /><h3><strong>6. Automate for Multiple Files</strong></h3><p>If you have many video and audio files, use a batch script:</p><p></p><ol> <li data-xf-list-type="ol">Create a new text file in Notepad and paste the following:<br /> <br /> <br /> [USER=98746]@echo[/USER] off<br /> for %%v in (*.mp4) do (<br />     set "video=%%v"<br />     set "audio=%%~nv.mp3"<br />     ffmpeg -i "%%v" -i "%%~nv.mp3" -c:v copy -c:a aac "output_%%~nv.mp4"<br /> )<br /> pause</li> <li data-xf-list-type="ol">Save it as merge.bat in the folder with your video and audio files.</li> <li data-xf-list-type="ol">Double-click the batch file to run it. It will process all .mp4 videos with corresponding .mp3 audio files.</li> </ol></blockquote><p></p>
