How do i add multiple sound effects (mp3) to a video (mp4) at any given time in the video ? [closed]
25 octobre 2023, par StudentProgrammerI am trying to automate my editing process. I have a video.mp4 with a given length, a folder with different sound-effects.mp3 and a list of timestamps = (t1, t2, t3...). I would like to be able to insert any sound-effect at any given time in the video. Furthermore a sound may last multiple seconds and overlap another sound. I've tried to visualize the concept with images.
enter image description here
enter image description here
Preferably this would be done in Python. However, I would be extremely happy if anyone took their time to help me out using any means of programming required.


I have tried using Moviepy without much success as I am only able to add sound to the start of the video. Perhaps ffmpeg is the way to go.

Uploading Reel to Instagram via API error : The video format is not supported
24 juin 2024, par Ben FoxI'm using
FFMPegto create a video with backing audio to upload to Instagram via the Graph API. I've followed the specs here as closely as I can : https://www.facebook.com/business/help/1197310377458196?id=376980407544978 and I've usedffprobeandMediaInfoto try and debug differences between my generated file and the requirements from Meta but every time, I get "Video process failed with error : Unsupported format : The video format is not supported. Please check spec for supported duration format".

I've tried doing binary uploads and supplying a URL via their Resumable Upload protocol with the same result both times.





I've uploaded screenshots from MediaInfo showing the entire breakout of the file and here is the code using the Node package fluent ffmpeg to create it :


await new Promise<void>((resolve, reject) => {
 ffmpeg()
 .size('1080x1920')
 .aspect('9:16')
 .autopad()

 .input(imageFilePath)
 .videoCodec('libx264')
 // .inputFPS(fps)

 .input(audioFilePath)

 .audioCodec('aac')
 .audioChannels(2)
 .audioFrequency(48000)
 .audioBitrate('128k')

 .addOption('-use_editlist', '0')
 .addOption('-movflags', '+faststart')
 .addOption('-crf', '23')

 /* .outputOptions([
 // YUV color space with 4:2:0 chroma subsampling for maximum compatibility with
 // video players
 '-pix_fmt yuv420p',
 ]) */

 // Set the output duration. It is required because FFmpeg would otherwise
 // automatically set the duration to the longest input, and the soundtrack might
 // be longer than the desired video length
 .duration(duration)
 // Set output frame rate
 .fps(fps)

 // Resolve or reject (throw an error) the Promise once FFmpeg completes
 .toFormat('mp4')
 .saveToFile(outputPath)
 .on('end', () => resolve())
 .on('error', (error) => {
 console.log('[render] :: Error', error);
 reject(new Error(error));
 });
});
</void>
