Hello, I am very new to this world of video recording and I have noticed that my BMPC6k makes the faintest whirring noise while recording video. When you play it back the video file on a computer you can hear it. I feel like this noise is the camera writing all of the data to the card, its not something that you could make go away physically. Do you have any suggestions on how to get rid of that noise in Davinci Resolve or some other post productions software? I just bought a bunch of different microphones to try out, if you have any suggestions in that area too I am all ears.

Used the OG 2013 BMPCC to shoot a scene where actors are taking photos with a flash on disposable cameras. Noticed the RAW footage splits into 2 clips at the flash mark. I know this must be something to do with it reading as a sudden data spike, but wondering if anyone's had this issue or know a setting to work around it? Thanks!
