ffmpegHow to delay (sync with video) audio channel in video file

We can use audio delay to fix unsynced audio/video channels:

ffmpeg -i in.mp4 -itsoffset 5 -i in.mp4 -map 1:v -map 0:a -c copy out.mp4ctrl + cyoutubegithub

`-itsoffset` delays input stream by specified number of seconds	`5` delay first input stream (audio channel) by 5 seconds, use negative value to trim instead of delay
`-i in.mp4` input video file (first - for audio, and second - for video)	`-map` map input channels to output
`1:v` use second input (index `1`) for video	`0:a` use first input (index `0`) for audio
`-c copy` do not encode/convert, only copy	`out.mp4` resulting video file
