Here is my situation: I recently got a new mic to use for my OBS (Snowball). However, it didn't pick up my voice at all. So I thought I'd changed the file size to tremendously large for this. When I did this, it picks up my voice but then it goes black screen on all my footage and made the files .avi instead of .mp4 . I switched it back to large files and it records my screen/game but not my voice. What do I do?
