So I have footage with four sound sources: my boom mic, the camera's (my iPhone) mic, and two lav mics on the two actors. The lav mics have the best quality so I want to use those two audio files during the video. One problem: how do I merge both of those with the video in perfect timing? I know Hitfilm can do it automatically with one audio file but can it do it with two? I used a clapperboard to help with manual alignment but I'd rather work with just automated processes and tweak it after!
