What program do you use for adding audio to 4k mp4 video files quickly? windows Media Center only goes up to 1080p.
i have some content that doesnt have sound that i want to upload to the internet with music for the betterment of humanity, but i don't have 10 hours to let blender spend rendering it frame by frame and piecing it back together in mp4 only to discover that it has been downscaled inexplicably for some technical reason.

mp4 doesn't support that tag

You can't store wav audio in an mp4 container. You have to convert the audio into something mp4 allows, like mp3

can i do this with ffmpeg ?
it would make it a lot easier to not have to open a 4th or 5th window every time
>>
>>56631533
ffmpeg -i video.m4v -i audio.wav -map 0 -map 1 -c copy -c:a libmp3lame -q:a 2 both.mp4
using "-c copy" and "-c:a ..." is valid, having "-c:a ..." after overrides the audio codec
video and any other non-audio tracks will remain as-is

>>56631791
also note, "-q:a 2" is the same as "V2", which might be more familiar
you can also used a fixed bitrate instead by replacing that with "-b:a 192k", for example
