FFMPEG TIME:
Trim the First 5 Seconds of the Audio and Combine with Video (will be silenced 5 sec):
Remove Original Audio, Add New Audio, and Shift the Audio Forward by 5 Seconds (same as before):
Just add audio to video (with replacing original audio):
Finally shift auido properly for 5 sec. without silence:

best compression using ZPAQ
(its very slow, but compression ratio around 30% better than ZST )
