Feature request: Increase data/bit rate of Blackmagic Camera
Posted: Sat Sep 14, 2024 9:42 amTesting the data rate / bit rate of the Blackmagic iPhone Camera app, I was disappointed to not see options to change the video data rate; the default appears to be very low.
Testing out a near exact video shot of 20 seconds with the same movement (dolly); I got some interesting results.
All video set to 4K 60fps HDR 10-bit HLG (BT2020 colourspace with 2100 transfer) with Dolby Vision HEVC; zero dropped frames. The below are average data rates for the video files captured:
iPhone native camera app: average 52 mbit/sec
Final Cut camera app: average 52 mbit/sec
Pro Camera app (set to maximum): average 120 mbit/sec
Filmic Pro app (set to maximum): average 120 mbit/sec
Blackmagic Camera app: average 38 mbit/sec
Blackmagic Camera seems to be very low in comparison. I re-ran separate tests and had similar results.
Please could Blackmagic give us the option to increase the data rates for video capture in the app.
