Yes, by far the best results are with dubbing the sound in later.
The way I did it last year was to still use the outdoor sound when i was recording it, but then I just used that audio as the "reference track" to sync the dubbed version perfectly.
The better software actually will do this automatically (like Final Cut).
Plus, when doing multi-angle cuts, its really the only way to get good sound (especially if some of the cuts are from the drone (which doesnt record audio).
Same here. Time is also why I haven't added video in a number of years. Plus with multiple houses, to feature them all, I have to splice it together.
