One of the biggest things that most amateur filmmakers or video makers make is not getting sufficient tone.
Before shooting, record a fairly long stretch of just the ambient sound in the area where you’re filming so that when you are editing, it can be laid under the audio tracks and help to smooth out the jumps in audio from different clips.
I’ve always just used the same ones that I use for performers because I’m poor.
If possible, make sure there’s no recognizable voices or anything like that because the tone will be repeated through the scene, so any voices are going to repeat as well. So when you’re doing it, tell your actors/crew to be quiet.
