Final Cut Pro X export fails! Missing RAM vtdecoderxpcservice

Hi, I just tried to upgrade at Ventura and Final cut 10.6.5 on my mac mini and they seem fixed something.

The finder alert pop-up keep come up, but after few minutes it refresh the memory and the exportation is successful.

I tried it with a fake project, because a won't upgrade my mac studio in the middle of the project.

What is the main workaround you are doing? I have found out that if I can open up QuickTime and screen record during the export then it will export the file without issues. It will take 2-3 hours which is significantly longer and is extremely frustrating. I use a Sony alpha A7 IV. Shoot in 4K XAVC. I also use a Go pro 10.

This fix has been temporary and is very frustrating for such a long export time, but at least has worked for one of my videos so far.

Thank you very much for this. You are not alone with the problem, which seems to be in M1 machines. What's supposed to happen is when the memory pressure builds up the system is supposed to stop the decode/encode process, release the memory, and continue. That's what I see happen when I run a long export. I experimented with a 60 minute project with a variety of formats and codecs, frame rates and sizes. The VTD memory would run up on some media and codecs more quickly, but release at 35 GB. I have a 32 GB M1 Max. I could crash the system with DNxHD media pretty regularly. The 10-bit H265 pushed the VTD up but it didn't crash. This is in 12.5 with 10.6.4.

Can you run Activity Monitor while you're exporting and see what happens, screenshots would be great, in the memory pressure? Is there an error message?

Someone suggested watching Activity Monitor and when the pressure builds up to play the project timeline. It probably forces the software to reallocate memory.

Hi(bonjour),

Did you try to send your timeline to compressor for encoding? Did you try to optimize media to prores as suggested by Tom?

Please give EtreCheck Full Disk Access for a full report.

There's an update volume on there that's odd though probably not doing anything. Install the Pro Video Formats from Software Update. Though it sounds like a software problem, there may be a hardware issue.

Are you running MalwareBytes continuously? Shut it down and run it when needed. Do you have Neat applied to the clips? Try the export with Neat disabled. What exactly are your media specs?

The SSD should be APFS formatted rather than HFS+. You should update the OS for security. Neither of which matter to your problem I don’t think.

I'll see if I can get around to testing that later this week -- although to be honest, with the amount of media I'm dealing with I don't see that as a practical work around for myself personally. Optimized media takes a while to make, and then it takes up SO much storage space. One of the biggest reasons I upgraded to the M1 is to stop having to create proxies or optimized media just to edit, and I kind of stubbornly refuse to go back haha. But still, an interesting idea and worth trying if you have this same problem and don't mind creating the optimized media.

well, for a 18min project in 1080p: Source footage 10bit, 8k and 4k 25fps and 50fps :

Bigsur crashes as soon as there is just one 8k included. With 4k it just works. (I need two to three attempts to render successful)

Monterey all footage crashes, 8k,4k 10bit, 8bit, simply crashes all the time.

BigSur runs on my M1MacMini, Monterey on my brand new full spec M1Pro, which I bought for video editing and which I can’t downgrade to BigSur.

My Cameras: Sony A7SIII and Sony A1.

thanks good to hear that I am not alone, I will cut a very quick video and will send it to the most famous Youtuber, they will hopefully pick it up as they are always keen to find unbelievable FCP or Apple bugs - that will hopefully help to generate a bit more noise - it is really unacceptable and very annoying, in particular if we all consider what we have paid for the apple products… anyway thanks for the tip, what I thought would work as well (but haven’t tried it out) is if you create a couple of compound clips. You can export compound clips separately if you go into the compound clip and then hit export. After exporting all clips one would need to stitch the exported clips together into a new project - a lot of work. The workaround I am using at the moment is a downgrade to BigSur and while exporting you can play the project which resets the service, works not all the time, but you will get there eventually, unfortunately this workaround doesn’t work under Monterey on m1Pro.
