I need to combine a movie without sounds and a MP3 file. How can I do it in OS X? I have Adobe After Effects but it is not at all intuitive to use -- or better I need to find some button to render the sounds with the movie but now no time -- is there some easy fast-to-use software for OS X to combine sounds and videos?

iMovie is the obvious choice. It's very easy to use and fairly reasonable in price. You might have it already if you have a newish mac or else it's $15 I think.

  • Awesome! Thank you so Apple way, clever -- worked like a charm without After Effect's slow rendering. Not professional thing but works :) – hhh May 15 '13 at 23:02

ffmpeg supports combining video and audio without re-encoding:

ffmpeg -i input.mov -i input.mp3 -c copy -map 0:0 -map 1:0 -shortest output.mov

-map 0:0 means input file 0, stream 0. -c copy copies video and audio codecs. -shortest makes the combined file as long as the shorter file.

  • The best and fastest choice to combine or merge audio and video files without re-encoding. Really useful. Thanks a lot! – GiovaLomba Nov 28 '15 at 9:53

Adobe After Effects

I remembered now how to do it in After Effects: Composition > Add to Render Queue and then click lossless and put the cross to the audio thing. Now specify the target and then hit Render.

A good video here how to do it.

  • Yet this solution is taking pretty long time do, hopefully someone able to provide a more casual way. – hhh May 15 '13 at 22:50
