Unable to import Arri RAW mxf in Davinci Resolve v18.0.1

Hello Freinds and BMD Support,

This weekend we have upgraded our workstations including Windows 10, Mac, and Linux CentOS 7.3 (advance panel), and stuck with a very unexpected bug (on Mac there is no issue though).

DR v18 is not recognizing the Arri RAW Mxf files and showing as media offline (seems like codec is not supported) also tried to drag and drop in the media pool and in a result, nothing gets imported nor any error message at all.

Arri RAW MXF file 640MB: https://sharpimage.wetransfer.com/downl ... 409/cf4afb

Is anyone experiencing the same on Windows 10 and Linux Centos 7.3 (advance Panel) stations?

Both the platforms are updated with the latest BMD drivers and GPU drivers!

Need urgent Help!

The files load fine here on Windows 10 Resolve 18.0.1build3 but I tested with their sample footage. Not sure if anything ever changed since.

Maybe test some of those too to be sure.

Can you upload a short test clip to a cloud service?

Arri RAW MXF file 640MB: https://sharpimage.wetransfer.com/downl ... 409/cf4afb

plays fine with resolve studio 17.4.6 on macOS 11.6.8

resolve studio 18.0.1 under macOS 12.5 does not see this file

and also resolve studio 18.0.1 under macOS 11.6.7 does not see this file

Hi,

Found out the reason, The shots I was using were trimmed in DR17 which are having import issues, Tried the original Arri Raw file and those were fine.
then I tested and trimmed a few shots in DR18 and got success.

CONCLUSION
So the conclusion is Arri RAW MXF shots must be trimmed in DR 18 if want to grade in DR 18, shots trimmed in v17 won't work v18.

Thanks for your replies guys!

Cheers!

So the conclusion is...

...always use the original media.

C'mon. If BM is programming a function like Media Management, such things should work. Or just kill the function! If you're working in documentary, you may need it, like for long observations in nature. Nobody can afford to keep hours of footage where an animal showed that specific activity for less than a minute.

What a nasty bug!

I've been working on a media managed project for moths and now I've got to go back to conform because DaVinci won't read the files anymore?? This is just ridiculous.

I would note that Tahir's conclusion is not actually valid either. There are issues with ArriRaw trimming in Resolve 18 related to 3rd party software.

Not only will ArriRaw files that were trimmed in Resolve 17 be offline in Resolve 18, but trimming ArriRaw files in Resolve 18 will also fail.

Hi Dwaine, So what is the Permanent solution then? Does it seem we can not use the V18 studio for real projects and stick to v17?

So we may need an official warning not to try and trim ArriRaw?

The hope would be that the issue is addressed in the 3rd party code.

Do you mean Arri is the 3rd party that has to look into this? (please correct me if i am wrong i am little confuse here)

When can we expect this fix? I have very burning projects that need to be done urgently. and keep 17 and 18 versions at the same time is not possible.
it is also not possible to roll back, since the project database has already been converted to version 18. Is there any way out? Yes i have a backup projects base v17 but some project have already been changed in version 18, which did not use arri raw

i conformed a ArriRAW project yesterday

exported a roundtrip @ cam orig raster / MXF @ DNXHR _uncompressed 16 float from ACES with IDTand ODT bypassed +5 fr handles

a bit of a sledge hammer, but it did take 80Tb down to 15Tb... we have around 850 VFX pulls on this film, so those are well under way automagicly, copy & rename, repeate 849 more times....

i have 16, 17 and 18 co-existing nicely (aside from the RED decoder and surface control) on all my machines

not that i have had any reason to use 16 or 17 in a while, but they do no harm hanging out on the drive

I use a project server and I have several machines connected for simultaneous work + remote rendering.
Because of this, I can't keep 2 versions.
Dai, when installing a new one, the previous one is erased, only if the folder with the program is not copied into a separate folder first.

converting to DNxHR is not possible for me because I need to conform the project with only source material trimming without any conversion.
There is also a problem with opening a previously conformed project that uses ARRI trimmed sources.
I have 160Tb of sources and after trimming it becomes 2-3Tb

source material rendered to uncompressed 16float through ACES with bypassed IDT/ODT are transparent to the source material - same as writeing 16float in an EXR wrapper

don't equate uncompressed 16float in a MXF wrapper -with- DNxHR compression in a MXF wrapper

i'v stayed on disk databases just to keep the ablity to have diffrent versions on machines, the downside of moveing a DRT about is trivial when compared to keeping a working version and a beta of the next version alive, makes transitioning pretty painless

"The hope would be that the issue is addressed in the 3rd party code."

I don't know if I understand it correctly but in version 17 everything works well with arri trimming so it should works the same way in 18. This situation right now is dramatics and is this issue should be repaired ASAP. We are not able to have on our online storage every source for a TV series, the trimming is a must have. Also working not on the source file is also bad idea because colorists are changing raw settings.

hello there

we also just encountered this extremely nasty bug which leaves us stuck at a bunch of projects at the moment. very unpleasant situation for our Postproduction so we URGENTLY need an update on the progress for a fix. will there be a solution in v18.0.2 and when can we expect a release??

is there any info on the 3rd party codec so we can try to mitigate this ourselves until a fix arrives?

any info is much appreciated, thanks a lot in advance!

Dear friends at BM, this is a terrible situation, I first tried to trim de ArriRAW material in the version 18, and it failed. Rolled back to 17 and trimmed the files, upgraded again and now the files are unaccessible. ArriRAW represents a big percentage of high end productions. Its really a no go for me in resolve version 18, and I was really looking forward to testing this new version....

Resolve 18.0.2 just went up. It has a fix for this issue.

Hi

Resolve 18.0.2 just went up. It has a fix for this issue.

unfortunately, I am stuck in the same situation. Having Resolve v18.1 and it's showing media offline Arri Raw mxf files on Linux as well as on Windows, whereas able to play in the media pool.

Please note: shots were trimmed in the same Resolve version on Mac.
Its an episodic show and conversion and working without trimming is not an option.

Any help?

[Dwaine Maggart]

If the files play in the Media Pool, hard to understand why they wouldn't work in the rest of the app.

Can you provide a link to a Resolve log and sample file that's not working?
