ImporterMXF (Importer:46) Error - ARRIRAW in Premiere Pro 22, 23 and 24 versions

[CVF Films]

I was working on a feature film shot on Arri Alexa Mini LF, footage was ArriRaw (no HDE).
The editing was going great until recently when opening the project, the relinking process at the start finishes faster, and i have a lot of shots (more than 40%) of the whole edit shows black in the program monitor with the error:

A low-lwvwl exception occured in: ImporterMXF (Importer:46)

Every time i scrub over or try to play these shots, the same error piles in the event tab.

The Current version of premiere: v24.0.0 build 58

Restarting premiere doesn't fix this but the shot that goes black are random and not the same shots from every restart and sometimes i get these errors also:

Frame substitution recursion attempt  aborting after multiple attempts on file: A00xxxxx.mxf 

and it makes the editing near impossible.

Things i tried to get this fixed:

- Restarting premiere

- Restarting the computer

- Clean media cache in-app

- Clean media cache manually in the source folder

- Delete all rendered files

- Reset preferences

- Reset all settings

- Reset plug-ins

- Try software-only rendering

- Go back to an older version of the project file (I tried v22 v23 and v24)

- Reconnect media files (Gives Error)

- Reinstall Premiere Pro after fresh format of windows

- Reinstall an older version of Premiere Pro

- Reinstall all of Adobe

Please Any help would be appreciated, I have a deadline to meet and i can't get any progress editing this project.

Hi @Cinema Vision27805116wvkg,

Sorry to hear about the issue. If you take the network storage out of the chain, and media is placed on the local SSD, does the situation improve? Please let me know. Our product manager in charge of this area, @Fergus Kousha, may want to weigh in.

Thanks,
Kevin

Thanks for the reply.

The footage is about 47TB so i can't put it all internally.

The biggest SSD drive i have internally is 1TB, I will try to copy on the ssd and see but i don't think that 1TB could give the big picture on the problem.

The thing is the problem is random with the footage and every time I restart it happens to a different batch of shots.

Something I didn't mention, I tried to play the shots that give black and not play in premiere while premiere is open, i tried to play them with ARRIReferance Tool and they play normally and smoothly without any problem, and i think that shows that the files at lease not corrupted.

Thanks

Hi @CVF Films,

Frustrating. I see the potential bottlenecks to be the remote drives and possibly the Xeon processors. Hopefully, we can get a response from the product team. Sorry for the hassle.

The one on one support crew won't be in until Monday morning, but that might be your next step. At that time, please contact assisted support directly to help you find a solution to this problem. The chat pod is in the lower-right corner of the screen there. Ask for the “video queue” to reach our digital video specialists. I hope they can help you.

Let us know what they say so that the community can stay informed and help others having trouble with the same situation.

Thanks,

Kevin

Hi @Kevin-Monahan 

Thanks for following up and for you help.

I worked with this setup on more than 4 feature films now, all shot on RED Cameras with 6k RAW and 8k RAW resolutions and the setup worked Great considering the data of the RED is much higher demanding than the ARRI, thant's way I didn't consider them as potential bottlenecks.

I have been also getting these errors:
- Error parsing properties list from "C:\......WorkspaceConfig.xml" (error code = 12) It hase been renamed to "LayoutsWorkspaceConfig.xml.old" for backup

- Error parsing properties list from "C:\......UserWorkspace_1.xml" (error code = 12) It hase been renamed to "UserWorkspace_1.xml.old" for backup

- Error parsing properties list from memory.

It happens everytime I reopen Premiere with this particular project, reseting the layout i had.

I tried to copy 1TB of footage to my internal NVMe and the Black footage with 

error:

A low-lwvwl exception occured in: ImporterMXF (Importer:46)

Still happened to a couple of shots.

I will Follow up with The one on one support crew and I'll post the updates here.

Thanks
