Hey guys,

I recently got myself a M1 Mac Mini, and immediately had issues with Premiere Pro crashing. After a ton of trouble shooting, I've realized the issue is with BRAW 2.2. After uninstalling it and reverting back to 2.1, all my issues went away.

Just wanted to give a heads up to the BM team and to anyone else who runs into this issue.

Cheers

I've had the exact same issue, I've downgraded to BRAW 2.1 and my problem was instantly solved.

Some of the symptoms I've noticed, if this helps any developers reading this:

[*] Premiere Pro: Zooming in/out in the timeline view when braw clips are in the timeline will occasionally cause a hard crash - the process is instantly killed with no crash handling. I didn't notice any spikes in RAM usage so I'm not sure if it's a memory leak or what.

[*] After Effects: A composition with a Blackmagic RAW clip may render the first frame (or first few) when starting playback, however after a few frames are cached, it no longer displays any video output in the Composition view window. If I remember, the screen either occasionally showed one of the frames rendered, no graphic at all (just the dark grey background color for AE's UI), or possibly a black screen that doesn't change.

Edit: I am running Windows 10 build 19043, NVIDIA RTX 3060 (Driver Version 30.0.14.7212), with Premiere Pro 15.4.1

Update: I've debugged both Premiere and After Effects when this problem occurs, this is the best info I can provide right now.

Exception thrown by Premiere:

Exception thrown at 0x00007FF98387BA0B in Adobe Premiere Pro.exe: 0xC0000005: Access violation reading location 0x0000000000000010.

Exception thrown in After Effects:

Exception thrown at 0x00007FF98E43BA0B (BlackmagicRawPremiereImporter.prm) in AfterFX.exe: 0xC0000005: Access violation reading location 0x0000000000000010.

By stroke of luck, the AE exception appears to be a bit more informative by telling us the exception was thrown in the importer plugin. If my intuition serves me well, the actual Blackmagic RAW codec in 2.2 is probably perfectly fine, however there was a change made in the Premiere importer plugin (during the development of RAW 2.2) that's causing the crash.



Edit 2: The MD5 checksum for my BlackmagicRawPremiereImporter.prm is:

4bd3903d6fd5ee3ad76f750fb49a7c27

It looks like the instruction is hex 0xBA0B from the start of BlackmagicRawPremiereImporter.prm, in a function that starts at 0xB710 and takes 2 pointers. It looks to be thrown within an if-statement along the lines of:

Code: Select all

if((ptr1 != ptr2) && (... < 0 || ... < ptr3)

, if that even helps. My initial guess is there's a null pointer here?

What version of Premiere Pro and what version of OS are you running?

Have you tried the Autokroma BRAW plug-in?

We just updated BRAW Studio 2.6.0 with BRAW SDK v2.2

Please note that any bug from within the official SDK will be also in our plugin BRAW Studio. But if the bug is only in the Importer, then we might not have this bug.

We also have a crash from the BRAW API v2.1 in macOS x86 Intel mode

Ahh, good point. I want to mention that I am not using BRAW Studio -- this problem is potentially happening within the importer provided by Blackmagic's BRAW installer.

We have not been able to reproduce any of these crashes so far. Any more info (maybe project files) or steps would be helpful.

So for me this issue was present in many scenarios.

I just got my Mac mini (M1) last week, which came preloaded with Big Sur. I downloaded the current latest version of premiere pro alongside BRAW 2.2 which is when I first discovered the issue. I then reverted back to the latest 2021 version of PremP. Still had issues. So I upgraded my MacOS to Monterey, still had issues. Keep in mind, in all of these scenarios I was trying both the M1 version and intel version of PP.

After all that failed, I reverted back to BRAW 2.1 and the issue disappeared.

Crashes would not take long to happen. Simply zooming into the timeline, scrubbing or opening a sequence would initiate the crash.

I've attached a project, hope it helps!

Thanks for the project, we are looking into this.

Hi, a 2.2.1 update which should address this issue is now available on the website. Thanks for the report and information.
