I have video.mp4 only file, and audio.m4a file. I need to merge them both, and I need the output to be the same video without creating new resolution or modifing caracteristics.

OS: windows 10

Thank you.

You can use command like this:

ffmpeg -i video.mp4 -i audio.m4a -c:v copy -c:a copy output.mp4

this will ensure no changes are made in codecs, compression and so on
