There's a bad batch export bug with Final Cut Pro, Compressor and macOS Monterey.

Let's first up say that Monterey has been the flakiest macOS that we have used for a long time. Although Final Cut Pro seems to work ok, we get general freezes, beachballs and the odd random restart. (This is without mentioning Safari!)  Only this morning we had to do a reboot as a machine had refused to wake up from sleep. Not impressed.

So when we received this information from an FCP.co reader, we thought it was worth sharing.

'Basically, if you submit a batch export from Final Cut Pro X to Compressor, it will usually, though not always, have every video in the batch fail out with “Unknown Error -9074”.

'Prior to experiencing this error for the first time in October, there was almost nothing about this error on the internet. Now there are numerous posts on Apple’s support site, where people are getting the same error although no one seems to know what it means.

Apparently Apple is aware of it but the issue persists. And yes, I’m not a dummy, I’m cautious when upgrading to a new macOS. I have two systems and I always update one of them first, use it for a couple of weeks and once I find the system to be stable, I update the other system.

In this case, the only thing I hadn’t tested was batch exporting from Final Cut to Compressor and, well, it got me lol. I should add - if I have say 30 mp4s that I need to transcode to ProRes, Batch Exporting in Compressor works fine. It’s something about when you send a project from Final Cut to Compressor that the issue occurs.'

So a word of warning here, if you are using Monterey you might experience the same problem. We believe it might only affect Intel based Macs, please leave a comment below if you know otherwise or have any more information to add.

I have also worked as a broadcast and corporate editor for over 30 years, starting on one inch tape, working through many formats, right up to today's NLEs.

Under the name Idustrial Revolution, I have written and sold plugins for Final Cut Pro for 13 years.

Current Editing

great house giveaway 2020

2020 has been busy, the beginning of the year was finishing off a new property series (cut on FCP) for Channel 4 called The Great House Giveaway. I also designed and built the majority of the graphics as Motion templates. It has been a great success and the shows grabbed more viewers in the 4pm weekday slot than any previous strand. It has been recommissioned by C4 for 60 episodes, including prime-time versions and five themed programmes. The shows have also been nominated for a 2021 BAFTA.

Tour de france 2020
Although both were postponed to later in the year, I worked again on ITV's coverage of the Tour de France and La Vuelta. 2020 was my 25th year of editing the TdF and my 20th year as lead editor. The Tour was the first broadcast show to adopt FCPX working for multiple editors on shared storage.

 

BBC snooker the crucible

BBC's Snooker has played a big part in my life, I've been editing tournament coverage since 1997. I'm proud to be part of a very creative team that has pioneered many new ideas and workflows that are now industry standard in sports' production. This is currently an Adobe Premiere edit.

Covid cancelled some of the regular corporate events that I edit such as trade shows & events. I was lucky however to edit, from home, on projects for Amazon Kindle, Amazon Black Friday, Mastercard and very proud to have helped local charitable trust Kendall & Wall secure lottery funding.

As for software, my weapon of choice is Final Cut Pro and Motion, but I also have a good knowledge and broadcast credits with Adobe Premiere Pro, MOGRT design and Photoshop.

Plugin Design & Development

I'm the creative force behind Idustrial Revolution, one of the oldest Final Cut Pro plugin developers. It hosts a range of commercial and free plugins on the site. One free plugin was downloaded over a thousand times within 24 hours of release.

I also take on custom work, whether it is adapting an existing plugin for a special use or designing new plugins for clients from scratch. Having a good knowledge of editing allows me to build-in flexibility and more importantly, usability.

FCP.co

Now in its 10th year and 4th redesign, running FCP.co has given me knowledge on how to run a large CMS- you are currently reading my bio from the database! Although it sounds corny, I am pretty well up on social media trends & techniques, especially in the video sector. The recent Covid restrictions has enabled live FCP.co shows online. This involves managing a Zoom Webinar through Restream.io to YouTube and Facebook. 

The Future

I'm always open to new ideas and opportunities, so please get in touch at editor (at) fcp.co. I've judged film competitions, presented workflow techniques to international audiences and come up with ideas for TV shows and software programs!

Hi, Peter. I only see this error when I try to Send to Compressor from Final Cut Pro. I've been able to successfully avoid the error by using a Compressor Setting as a Share Destination instead of Send to Compressor.

Peter, thank you for giving visibility to this problem. On 24 Jan I discussed this with Pro Apps support and demonstrated it during a remote support session. I then filed the bug using the Mac Feedback Assistant app (what replaced the previous Bug Reporter app used by developers). See below.

Sometimes an OS update can expose a bug in an app, and it can be ambiguous whether the system or app layer is responsible. However this bug is in a very common procedural path. My former product manager would have had our hides if we allowed something like this to ship.

Title: Compressor transcode hangs followed by error -9074 on x86 Monterey if FCP batch contains titles

Description: If a new batch is sent from FCP to Compressor which contains a clip with titles, then that batch is started using a built-in export preset such as ProRes 422, if on x86 Monterey, Compressor will frequently hang during transcoding then after about 4 min 30 sec system error -9074 is raised. This is unique to x86 and Monterey and does not happen on Apple Silicon or x86 prior to Monterey. The failure is consistently reproducible and persists after FCP and Compressor are removed and re-installed and if using a new MacOS user account.

Reproduced using FCP 10.6.1 and FCP 10.5.3, Compressor 4.6 and 4.5.4 on x86 Monterey 12.1.

Spindump indicates the failure happens within about 1/10th CPU sec and most threads get stuck on synchronization objects.
