Graphic card render problem fcpx

Not all graphics cards play nice with FCPX. One FCP.co reader has been getting bad artifacts when using his Sapphire 7950 Mac Edition GPU. Take a look at the video.

Oliver Holtkamp, Head of Postproduction at  Schnittchen Köln in Germany sent us an email describing the errors he is seeing when using the Sapphire GPU with Final Cut Pro X. He also sent us some videos which we have put together to show the vertical lines which appear during transitions. On our demo video, the effect in real time is followed by the rendered video paused with arrows to show the errors.
He says the problem is making him crazy!


As Oliver says, he needs his effects, he produces a popular rated TV show for a major broadcaster in Germany. The broken vertical lines at a third and two thirds across the picture that appear during transitions make the exporting of a broadcast master impossible.

Sapphire are saying it's not them, Apple have acknowledged the receipt of his information and the plugin companies say the problem lies in the driver for the card. Oliver found this from Neat Video:

"FCP X 10.0.8: there is a known problem in FCP X itself, which may cause FCP X to produce visual artifacts (vertical lines) when running on AMD Radeon HD 7950 while plug-ins of certain type (Neat Video is one of them) are used. The artifacts are produced by FCP X itself and Apple is currently busy trying to make FCP X work correctly with Radeon HD 7950 in such situations."

In defence of Apple, the Sapphire 7950 Mac Edition GPU (Which uses AMD technology) isn't on the list of approved OpenCL capable cards that are qualified for use with FCPX. They also state that they are working on the situation which is good news as it may offer up more GPU choices and hopefully more powerful card options.

So the bottom line has to be stick with the list of approved OpenCL capable cards that Apple publish. We do feel sorry for Oliver however and hope an upcoming update will fix his problem.

I am the Editor-in-Chief of FCP.co and have run the website since its inception ten years ago.

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.

I was made a Freeman of Lichfield through The Worshipful Company of Smiths (established 1601). Though I haven't yet tried to herd a flock of sheep through the city centre!

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.


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!
