I record footage with OBS and do voiceovers recorded in audacity. I process the audio in audacity, then sync the audio with the video. However, since I started doing it this way, the audio and video are not syncing up.
It starts out fine with a definite sync point (countdown from 3 and then I do something like click on something) but as the video progresses, the video starts lagging behind the audio. near the end of a 20 minute video, the disparity is nearly 3 seconds.
Someone brought up framerate. the footage is 30 FPS and Lightworks lists the audio as 24 FPS. The mic is set to 44100 Hz as well, if that helps.
