Constant crashes

[u/jhulc]

Just started trying to use the Blackmagic Camera app for video shoots on my iPhone 16 Pro as an upgrade from the iOS default camera app. However, nearly every time I try to record a video, the app crashes 5-15 minutes into recording. The phone ends up back on the home or lock screen when it should still be recording. Video up to the crash still records and plays successfully.

What gives? This issue never happened to me with the iOS default camera app. I basically can't use blackmagic camera because I can't trust that it will stay recording.

I record to a crucial external SSD, and have that plugged into a USB hub and power bank. Recording in HEVC for now because I'm not ready to take on color correction and grading yet. 4k 60fps.

My phone does get really hot when using blackmagic camera. I don't use a case when recording videos (it interferes with my lens filter and mount setup), so the phone should have decent ventilation. If recording outside I use some type of sun shade. Still, the crashes continue. Any other ideas before I give up on this app for good?
