Tried a bunch of different mic settings at a show. The best combination — the -10 dB switch on, with the foam windshield fitted (turns out it doesn’t just protect from wind, it also helps against overload). Sadly, I still couldn’t get perfect sound, even though the gig was pretty loud. But it’s a lot better than the first attempts. The drums still get clipped in places.
I also lowered the recording level on the camera itself in the settings. Around 50% gives better sound. Going lower just makes the final video quieter without removing the clipping. Here’s the result:
I’ll keep filming at other gigs and figure out how to better isolate the mic acoustically so everything records cleanly.
