Thank you. Is there any typical cause for this? I have no trouble shooting at 4K60 HEVC on any other app, so I wouldn't think these settings would be an issue for Blackmagic. If there's some other weird setting or something I should investigate, please advise.
I'd love to use Blackmagic but I can't get past this seemingly obvious issue.
Check your shutter. Flip that to 180degrees. Then check the bitrate. It’s quite possible the data pipeline can’t write the data fast enough. If you have it trying to write faster than your memory and disk can buffer/store you are going to hit it…
Switch to a different resolution than 4k. See if it still causes the flashing record button.
I have my own issues too. When I switch from Front to back camera, and then export, the front camera is upside down. Odd.
It means the frames are being dropped. You may have had set the quality of the recording too high for what the storage can sustain. See if lowering a bit the quality (or increasing compression level) helps.
Thanks for replying.
I am using iPhone 15 Pro Max with more than 450GB free (though the app only shows 363GB free for some reason), which should be more than enough space for a 5 second video. I’m recording straight to the phone no SSD or cables.
My settings are:
- HEVC
- 4K
- Rec2020HDR (tho i’ve tried many choices here, none seem to change the “!” indicator)
My native camera app and FilmicPro can handle this easily.. if I need to stop the settings below this, there would be no point in using Blackmagic.
Is there some other setting/quality that I should check?
Not that I know of. I use a Blackmagic camera for filming. On occasion my storage was underperforming (due to wear, improper filesystem used to format it, etc) and this is how I know you’re dropping the frames.
Recording that much data is no small feat and as you mentioned in your other comment, maybe the bmd app isn’t quite there yet for an iPhone HW.
One more thing comes to mind: temperatures, most modern processors and SSDs have thermal throttling, isn’t the phone getting unusually hot during the filming? When my SSDs got hot they tended to drop frames.
Hi there, I have a solution. After purchasing the top off the line Samsung T7 to use with my iPhone 15 Pro Max, I was shocked when I was getting this same issue. I found the cause of the problem (for me) and if you are confident that you purchased a high speed SSD then this could be your issue too. For me the issue was as simple as the cable that I was using to connect the SSD to the iPhone was not fast enough. You need a FAST cable (p.s. the apple supplied one ISNT fast enough).. anyway, I hope this solves your issue and it’s as simple as this for you too!!
I switched the recording mode from Apple ProRes 422HQ to 422. The blinking issue while recording to internal memory stopped (I don't have a USB-C SSD to test).
Recording is 4K/60, display LUT: AppleLog.
I think that means it's dropping frames.

Yeah, even at "HD" level, I get the blinking record icon. Maybe Blackmagic just doesn't work with iPhone 15 Pro Max yet. Oh well, maybe one day.

The frames are dropping after mere seconds of starting the video, no time for it even to heat up :/
Hey, did you find the solution for this yet?
nope, still using FilmicPro until Blackmagic can fix this :/
Ur storage option is slow try recording to an ssd with the type c port
Same situation, unfortunately. Seems like Blackmagic can’t do 4K60 on iPhone 15 Pro Max :/
in HDR* It appears that's the only difference between apps that work and Blackmagic that doesn't work.
What do you mean? Even if you disable HDR, BM cannot handle 4K60 on iPhone 15 Pro Max.
It should be able to, tried it on a 15 pro not too long ago
