How to replace the audio track in 4K video and not wait for a long processing time?

Question

Video

Hello. I need to change the sound in a 4K movie from an English track to Russian, so that when uploading somewhere there is a different language, the track itself is not in the file, and I have to change it through adobe AE, which takes an average of 8 hours. Can you please tell me how to do it much faster?

Try ffmpeg

ffmpeg -i <исходный файл> -i <звуковая дорожка> -c:v copy -map 0:v:0 -map 1:a:0 <результат>
