Hello Avid Community! First time poster here

I've recently encountered the above error when trying to render a Timewarp effect (FluidMotion).

I am currently running Avid 2022.4.0.56108 on macOS Monterey (12.1) on a Macbook Pro.

I've attempted to look up this issue before but have run in to the same Avid KB article about checking permissions. All permissions for Avid MediaFiles and Avid MediaComposer itself are set to Read & Write for: Myself, everyone and wheel.

I only have one drive on this machine and it is my Macintosh HD. Transcoding works, as well as AMA Linking.

It is strange that I can use Avid properly (minus this effect issue), yet it's spitting this permission error!

System specs are below

Thank you

Nick

Update:

This was fixed by creating a new APFS volume/partition in DiskUtil, then migrating my Avid MediaFiles to the root of that drive. 

Thanks 

Hi Nick

Randy Rike, One of our forum moderators explains it nicely in this post.

If the read write is correct then this is what will fix it.

Unfortunately, the CREATE APFS VOLUME option in the Disk Utility menu is grayed out. If you have another suggestion for creating one I would love to try this idea.

Thank you.

Hi Stephen,

See this link for more info:

Add, delete or erase APFS volumes in Disk Utility on Mac

You should be able to:

Go to Diskutil > (with the top volume selected) Create new APFS volume > Migrate Avid MediaFiles

Is there any reason you can't create the new APFS volume?

Thanks

Nick

Hi Marianna,

Thanks for your reply.

Looking at this further, it looks like this is causing issues when Avid MediaFiles is nested inside folders (as opposed to the root of a drive), even when permissions are set correctly

The original file folder structure for Avid MediaFiles (upon install) on macOS is:
/Volumes/Macintosh HD/Users/Shared/Avid MediaFiles

When said folder is in this location, certain things can't be performed (i.e. rendering effects).

Once Avid MediaFiles is moved onto it's own drive and the folder on the root of the drive, the issue resolves itself.

Is this something that can be passed on to the developers? Or is this a more Apple-centric problem...?

Thanks!
Nick

I had this same error message when trying to mixdown a sequence to OP1a on a Mac M1 Pro running Monterey 12.5. I ran first aid on my Macintosh HD using Disk Utility, relaunched avid and that fixed the issue.
