BMD Desktop Video causing Premiere Pro to Freeze Playback

[Jeff-LCBC Video]

In my facility we have a number of PCs that are running Premiere 2024 and Black Magic desktop 12.7.1. We have been encountering a bug that only happens when transmit is enabled. With transmit enabled, Premiere will randomly, yet consistently, stop playing video in the program monitor, view and external display.  We can move clips around, drag the play head, but no video will update. The only way to get video to play again is to reboot Premiere.

Premiere Pro 24.0.0

Microsoft Windows 11 Pro

HP Z4 G4 Workstation

i9-10900X CPU @ 3.70GHz, 3696 Mhz, 10 Core(s)

64.0 GB
NVidia GEForce RTX 4090
Blackmagic Intensity Pro 4K outputting to an Eizo colour edge monitor

No system compatibility issues reported in Premiere.

This is happening in multiple projects and actually on BOTH of our edit PCs, which are significantly different from one another in terms of hardware. Some of the projects have graphics, some don't as yet.

Every 10 mins or so, the image freezes in the program monitor and therefore the image on our Colour Edge. Premiere is otherwise still functional - I can still cut and move clips etc on the timeline, just can't see what I'm doing.

Have helf shift and reset everything, cleared cache, stopped other apps in background, done a general PC cleanup, tried different workspaces, toggled mercury transmit on and off, updated drivers across entire PC inc graphics card and Blackmagic Desktop Video software.

Don't want to roll back to 23 as all the work done in the new projects will be lost as they won't be openable.

Anyone else experiencing this?

not this exact problem but performance and stability problems over all for the past 5 days now. i have these problems. ill copy the link to the post because im kinda sick of writing everything down every day for the past days haha. my last answer describing the whole thing the best. i see a lot of forum posts that a lot of People having issues after updating to 24.0

I also have the same problem. The one thing you and I have in common is black magic. Is this because of this?

[Namsoo26521545ietd]

And I had the same problem since version 23.6. So I rolled back, waited for the update, and installed version 24, but it still happened.

I might try editing without external monitoring today to see if the problem persists.

[Michal Zizzo Židzik]

Hi. I have the same problem.
PrPro 24 with Blackmagic Intensity Pro 4K. (PrPro23 same issue)
I also did all updates and resets, but issue still persists.

Today I tried disable blackmagic preview, PrPro works without problem. So I think, it is definitely Blackmagic driver issue.

I've subsequently been on the blackmagic forums and have found this to be a known issue but one that BMD don't currently seem to be engaging with. It might help if more people contact them directly via their support pages to let them know. 

They're currently advertising the product as being compatible with Premiere Pro but it clearly isn't....at the moment at least.

I'm also having this problem but we're not shooting on Black Magic we are shooting on a RED.  Any answers?

[Carlos Ziade]

did you try to detach the external monitor?

if this solves the issue, the culprit is in the playback to external monitor,

you will have to let us know how are you connecting it to your editing platform?

if yes and the issue persists, try to delete the render files from sequence.

also consider changing the video preview settings from sequence settings

to QuickTime rather than H.264.

Thanks for the reply

did you try to detach the external monitor?

Yes, the problem persists whether monitor is actually attached or not. the only thing that prevents the problem is having Mercury Transmit unchecked in playback preferences.

if this solves the issue, the culprit is in the playback to external monitor,

you will have to let us know how are you connecting it to your editing platform?

Blackmagic cards outputting over HDMI. One PC has a Decklink Mini Monitor 4K. The other has a BM Intensity Pro 4K. Both computers are experiencing the same issue.

if yes and the issue persists, try to delete the render files from sequence.

I should reiterate that this is happening in ALL projects across both PP 23 and 24 including newly created projects from the outset. I've cleared cache and reset preferences multiple times to no avail.

also consider changing the video preview settings from sequence settings

to QuickTime rather than H.264.

I'm already set to Quicktime 

Thank you,
Ed

I'm literally going to stop using PP today.  I've spent way too much time troubleshooting when I should've been actually working.  This is ridiculous for the prices we pay we should not be dealing with this mess.  Unresolved bugs and problems with the software have been too common in this program.  It's been a job itself finding out wth is happening and why things aren't working properly.  Smh goodbye premier pro

[JaimeGomez78]

Same here. Intensity Pro. Always worked fine until this 24 version. Playback freeze. Averything keeps working, even save the project but have to restar to playback againg. Avery version of premiere had a gift for us... Im very happy.

[fatihdiragg]

Same issue since the update to the 2024. And it does with every camera that we've used so far (canon, sony). We don't get this on macs and macbooks in the office but only on PCs.

Hello;

This is a common issue related to mercury transmit with Blackmagic ouput cards ou AJA output card. No solutions suggested by Adobe (of course...).
Don't waste your time to reinstall Premiere, reset preferences, import your project in a new fresh one, etc. Don't wast your time to update your Blackmagic drivers (12.7.1 has still this problem).

It's an Adobe / Blackmagic related problem.
The only workaround is to output Mercury Transmit through a GPU output instead of your video card output.

[ShaneWalker]

23.5 is working, we will be holding until further notice.

[Bruce Bullis]

Specifically, what BMD devices are you using, with that 12.7.1 driver?

[Jeff-LCBC Video]

Decklink 4k SDI 

Ultras Studio

Decklink 8K Pro

[Jeff-LCBC Video]

We don't have this issue when using Pr 23.0.0

[Bruce Bullis]

Confirming: You're seeing the same/similar behavior, across numerous BMD devices, all using BMD 12.7.1 drivers, and all using PPro 24.0, on Win11?

[Jeff-LCBC Video]

Correct and on Windows 10 as well.

[Iamu Bob]

I use RED not Black Magic and still have the issue 

[default2zoqqaub9re7]

Not seeing this so far with an ultra studio 4k mini.  @Jeff-LCBC Video, can you please post screen shots of your playback prefs and audio hardware prefs?  Thanks!

[JaimeGomez78]

Update: Update to the last 24.0.3 and........the same. kepp freezing. Thanks adobe.

I got excited when I saw a new release this morning only to find it appears to be even worse! It seems to freeze instantly now rather than allowing 5 mins of work before doing so.

I'm also having no luck via BlackMagic support. Their guy copied and pasted some suggestions from a website he'd found and they were suggestions that didn't even relate to Adobe Premiere. eg. 'Reduce the RAM preview frame rate in the Preview pane'. This sounds like some other software - maybe DaVinci? Anyway, it's not going well...

In reply to Iamu Bob, this thread is about a problem relating to Blackmagic i/o cards, it's nothing to do with Blackmagic cameras. The type of camera used is irrelevant here.
