If you have Adobe Premiere this is extremely easy to do. Simply select your audio + video clips > Right Click > Merge Clips > Click Audio > Click Remove Audio from AV Clip > Done – Now drag to your timeline.
Otherwise, you could use third party software like Plural Eyes. Or just do it the old school way – manually.
