For those wondering about clearing out the system data: I've only been able to do is to switch over to the iPhone Camera App, make sure settings are set to 4k ProRes (or whatever is the highest bitrate), and just hit record until you get pretty close to full on storage. Then when you stop and go to record again, there should be a button that pops up that says free up space. It usually only pops up when there's 10 minutes or less of space (it's unpredictable). Click on that and it should free up some of that system data. Then I'd record again for a couple of minutes and repeat the process... making sure to leave keep storage pretty full. After a few times I'd go back to storage settings and see if it freed up the system data. Sometimes even just switching settings back and forth between 4k30 and 1080p60 forced that button to show up. And that's the whole idea - getting that free up space button to show up. Once I did that enough, the system data slowly goes all the way down, and then I would go into the Photos/Gallery App and delete all of those videos, and then clear them from Recently Deleted within the Photos/Gallery app. Super clunky I know, but if you can keep getting that button to pop up in the Camera App, it will eventually clear all the system data.
Hi. Thanks for the knowledge you share. I’d like to simulate on the BlackMagic app Cam the product showcase mode that the Sony ZV-1 camera has. Is it possible? Best
Thank you so much for this solution now when I delete my clips it does free up space. But still it seems that I can’t free up my « system data » that previously deleted footage on the Blackmagic app already used. Did you manage to delete yours? And how?
So the only way I found to kinda worked for that is to switch over to the iPhone Camera App, make sure settings are set to 4k ProRes (or whatever is the highest bitrate), and just hit record until you get pretty close to full on storage.

How did it go? I found that by offloading and deleting the BM app completely, and then turning the iPhone off and on again resets the system data. Went from around 85gb down to 5gb.
My blackmagic app is only showing 17gb total space and I only have 4gb taken up by the system cache. That's still nowhere near the 80gb of free storage on my phone.
Hey thank for the tip about freeing up space. What adapter do you use and how to you power up an external drive and iPhone to move the media from iPhone to drive?
For our iPhone 14 Pro (lightning port) we used the USB camera adapter. www.apple.com/shop/product/MK0W2AM/A/lightning-to-usb-3-camera-adapter If you have USB C, you'd need something like their multi port adapter that has 2 USB ports.
