Curious to know how you are syncing your audio with the video recordings. Is there an easy way to do this or are most people just using a screen recording software?
Ex: you play back a time coded track, record the video in captures built in recoding. How are you getting the audio synced in an efficient manner?
You could use a sync frame (like a film clapper used to do in the past). This means that you use a count in with the sound of a metronome syncing to flashing a certain light before the bit that you want to actually use in the final clip. This way you could easily put it together.
