A new app from Marquis Broadcast allows users to media manage FCPX Projects to just the media used on a Project timeline. We take the WORX4 X beta for a quick spin. (Spoiler- We already think it's great)

Ever since Final Cut Pro X was released, we have been asking about proper media management. Yes, there is the facility to consolidate used clips to a new drive, but that involved swopping the media  locations. Hardly a one click procedure. The big disappointment was that it copied whole clips, even if you had only used 2 seconds out of 30 minutes!

Marquis Broadcast has developed an application called WORX4 X that takes a Project XML, copies and trims the used media (with user definable handles) to a new location with a new Project XML linked to the trimmed media. With a bit of tweaking, you can also set this up as an export location. If the company name sounds familiar, you would be right as they are also the developers behind X2PRO.

Although the application hasn't been released yet, we decided to give the beta a go and see if it had really answered our media managing problems.

There are some caveats with WORK4 X.

You cannot use RED media at the moment, uncompressed audio & retimed clips take the whole clip as do sync clips. Unfortunately, it looks like QuickTime reference movies also are not trimmed. 

So what better to test out WORK4 X than a corporate job made almost entirely of camera originals (not RED).

The final project below was an edit of about four and a half minutes. You can see it is made up of short sections from a lot of interviews.

Exporting that Project XML into WORK4 X shows that the Project can be trimmed down from 92.5 GB to 4.83 GB!

Only one thing for it, hit the button!


WORK4X managed to copy and trim all the media from this sequence in about one and a half minutes.


The new trimmed media is placed in your destination choice. The text file is a report on the start size & end size of the project, which clips have been trimmed & which clips have been copied. As you can see, the new folder reflects the new size of the project media. 


Just to test, we closed the original Library, made a new library and then imported the XML of the new project. 


It nearly all worked perfectly. Everything was there apart from the interview sound, which is pretty important! The trimmed clips in the folder have audio, but apart from the first interview, the audio  doesn't appear on the Project clips in the Primary Storyline. This might be because the project originated in 10.2.3.

We will feed back this issue to Marquis. A shame as the copying & trimming even retained all the audio levels and fades in the secondary storylines. This is a beta and strange things do happen.



WORX4 X is VERY good news for FCPX users. Not only does it add back the much needed trimming media managing function that we were so dependent on in FCP7, it has also been thought out well. Making an XML of the new Project means you can bring old Projects straight back into new Libraries. 

It is still in Beta, so some of the limitations might be lifted when the application is launched. Hopefully the audio bug will be fixed too. When fixed & released, it is a real no-brainer purchase for FCPX users to want to keep separate copies of their finished masters. No word on price yet.

So a good start, we are looking to test out much more complicated Projects with WORX4 X - it will be interesting to see how it copes with complex multicams for example.

We will be attending BVE tomorrow (Tuesday 28th) where we hope to speak to Marquis Broadcast who are on stand K52. We might see you there!


We did indeed speak to Chris and Simon from Marquis at the BVE show in London. A few extra things we found out;

  • The app should be available from NAB time
  • Slomos such as 50% should work ok, complex retiming with reverse speeds probably won't work.
  • They are actively looking at getting sync clips to work before release.
  • QuickTime Reference files are a challenge, no immediate fix but they are looking at it. (Sorry EVS users)

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!
