Decode using hardware acceleration M3 Pro media offline

Hi,
since upgrading to a new m3 pro mac (sonoma 14.2 and DR studio 18.6.4) laptop I often get random media offline errors in the timeline during editing and timeline playback. The clips are online in the media pool. It's simple Sony 10bit slog 3 material. Nothing special in the timeline.

I edited on an m1 before with the same material without problems. I can't get any exports done. Neither via quick export, nor on the delivery page.

As I get this error on export:

renderfailes.jpg (52.18 KiB) Viewed 5835 times

I disabled Decode H.264/H.265 using hardware acceleration in the decode options. Now it renders fine, but playback and export is very slow - of course.

Anybody with an m3 pro had similar problems or found another solution? Its driving me insane...
Thanks.
Andre.

Exactly the same situation for me. Davinci Studio 18.6.4 Build 6, Macbook pro M3 Pro.

I'm getting the exact same error! I've been googling and searching for the past couple days and no answer.

I have tried every possible solution from downgrading Davinci Resolve to 18.6.3, Disabling all render caches and changing previews etc.

I'm starting to believe its a bug with the m3 chips

Davinci Resolve has destroyed my project. Do you if there is any recourse we have?
It continually randomly unlinks my media clips resulting in Media Offline.
It is an unusable platform.
Is there anything I can do to keep 1 years worth of work from being trashed by DR?

Thank god I am not the only one... I hope this gets addressed by BM...

@jstew1022 Did you try to disable the h.264 hardware decode in the decode tab under general options?

Andre.

Hey, i have the same problem so many projects crashed in the export. A solution is to change the render speed to 5 but that's not the reason to buy a M3 Pro to reduce the render speed nearly to zero. I love you all if somebody find a solution for this ****.

I think I've singled the problem being to a glitch within the new M3 pros and Davinci. I've spoked to two other people and they are both running into the same error.

Hopefully Blackmagic fixes this issue ASAP!

Well, looks like I found my people! I made a post earlier about the same issue here: https://forum.blackmagicdesign.com/viewtopic.php?f=21&t=194673

M3 pro here aswell

BM will be looking into it if the files are supplied.

Still having this exact same issue. Blackmagic get it together!! This program is unusable for M3 Pro users currently.

Yes. It hurts everyday. I hope bm is aware of the problem and can fix it soon.

The problem is NOT fixed in the latest update DR18.6.5

Is it not a problem with Sonoma 14.3?

No, I think it's related to the processor M3 pro and its hardware decoding of h.264/h.265.

Main Concept: “ HEVC, AVC & VVC: Solved encoder and decoder compatibility issues with Apple M3 processor”
Looks like BM has some work to do.

What do you mean? Sorry, I don't understand...

Well, obviously there are problems and MainConcept has already fixed it for their software.

The problem is NOT fixed in the latest update DR18.6.5

Can also confirm DR 18.6.5 did NOT fix the issue.

Hey all,

I have the exact same problem and it has driven me nuts the past few weeks since I bought my M3 Pro MacBook. Slowing the Render Speed to 5 seems to be working for me, so thank you for the tips. I haven't figured out how to change the decoding settings though - probably not possible in the free version of DR.

I am posting this so that Black Magic hopefully becomes aware of the issue - I was really relieved when I saw that it seems to be a systematic issue related to M3 Pro chips...

Please, change something BM!!!

Any lucky with this issue? I'm still having the same problem on Davinci 19 beta...

Hello, still no luck.
In contact with Support team, I hope that users of M3 Pro chips will be able to enjoy working with h.264 422 10 bit files in Davinci Resolve very soon

I have a iMac with M3 processor.
Although my clips are on the right position on my map/harddisk, I always get Media Offline.
What is the solution ?

For the time being, convert to ProRes as a workaround until there's a fix.

You scared me...
I'm currently working on M3 pro max with Panasonic HD/4-6K, H.264/265, 24-60 fps 422-420 10 bit files
and so far I have not encountered this problem
all my files and projects are on the same external ssd
I also work with Apple Log H.265 422 10 bit and everything is ok too
Decode H.264/H.265 - enabled

Could it be that all those experiencing it are using files out of Sony cameras?

Hi, I guess only users of M3 Pro base model are affected (not M3 Pro Max chip)

Could it be that all those experiencing it are using files out of Sony cameras?

Sadly, no. I use files from Panasonic Lumix 422 4k 10 bit H.264 Vlog and experience the same problem on M3 Pro

There were M3 Pro Max users reporting it too.

There were M3 Pro Max users reporting it too.

I have Sonoma 14.5
and I have all projects and all files on one external SSD
Maybe there is some kind of pattern in this that there is no problem?

Difficult to tell, since M3 always comes with Sonoma.

Man, I have been searching for this answer since Boxing Day! I was so excited to get an M3 mac, and then ran into this problem almost immediately, but only with 4k XFAVC files from my Canon C70. 1080p files were always fine, and files from my C300 too, but its been very frustrating. I was too specific in my googling before but finally found this thread. While its still annoying, I can leave the decode option on, edit with my proxies, and then turn it off before the render.

I had a ticket in with BM support and they hadn't heard of the issue, so I forwarded them this thread, and hopefully it get addressed soon!

Justin, Hello, thank you. You are not alone experiencing this issue

I tried to describe this problem as detailed as possible in 19 beta thread with links to other threads of people with the same problem.
The issue gets more obvious and hopefully the BM support will hear users of MacBook with M3 Pro chips

I have a ticket with BM support as well, provided as much information as I could during one month but haven't heard from them since May 29th.
I truly hope the Team took this issue into account

The only workaround I found for now is the same as yours: creating ProRes proxies and working with them.
It is ironic because I wanted to buy M3 MacBook so I could work with original files fast

It's annoying, since FCP-X works.

I just bought a M3pro Macbook pro (base model) and i was having trouble exporting and with the media offline preview of a clip.

I did not have any of these issues in the public beta of Davinci 19.
For Davinci 18 i did have all of issues, but i was able to export.

What i did was went to the Edit tab and highlighted all my clips, went to CLIP (on the Nav Bar) and Checked Render Cache Color Output and also went to Render Cache color Output and selected On.

Afterwards i was able to export my video.

For reference i was using footage from my FX30, 10-bit 4k, 4:2:2 footage

Hopefully this helps

This issue is solved with the Sequoia OS
