So how fast does FCPX work with 3344 clips and 5.5 terabytes of data?



We have all seen how snappy the operation of Final Cut Pro X is in demos, but what about the operational speed with a large real life project with lots of clips and keywords?

FCPX user Chris Blyth has had a frustrating time working FCPX that we will attempt to show by posting his YouTube videos. It looks like everything slows up when drawing thumbnails and trying to apply keywords when you have a lot of clips. Maybe he is doing something wrong and a reader will be able to chip in with a tip, however we have a gut feeling that the slowdown is caused by the sheer amount of data and clips he has.

Cris Blyth contacted us about our post and felt that the videos weren't really for prime time yet so we have removed them. We think we can sum up the videos by saying that using that amount of clips and data really bogs FCPX down. He asked us to point out that he personally feels that Apple is really working hard on these updates, and thinks that they will resolve them soon too.

"I don't think the problem is the amount of clips in total, but simply how many are shown at once. i.e. once you split them into Event's or keywords, it really becomes a very quick tool. - oh, also, it wasn't 3344 clips, it's actually over 16,000 clips. Think of having 16,000 clips in ONE bin in FCP7.. I think not. :) The fact that FXPx manages it at all is impressive."

He admits to liking to test things properly and has offered us a more detailed report when he has finished working on his latest project that was shown in the videos.

"We just returned from filming for 2 months in Africa with 5.5 TB of footage. We have several systems; one that is a standard FCS7 setup and another that is setup the same, but running·FCPx. Now, for the FCS system we had to transcode that 5.5TB of footage and that data is around 18TB. So, we wanted to try out FCPx but without all that transcoding."

We are going to look forward to Cris's further findings on how FCPX deals with large amounts of data and clips. No stranger to spending a lot of time in front of a computer screen, he was a vfx supervisor at Digital Domain and now directs commercials and makes documentaries.

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!
