Worx4 X is a new application for users of Apple FCP X, which solves the problem of needing to consolidate, and trim media used in one or more Projects.

Worx4 X takes an FCP X XML that contains one or more Projects. It works through the XML finding all the media references, adds handles, joins any overlapping references and then copies just the used portions to a new directory.

Finally it writes the XML back out, into the same directory, but having adjusted the media references to point to the new media, and all the start times of the references to reflect the new trimmed lengths of the media. 

 

Worx4 X Features

 

 

Application Use

The first version of Work4 X can only consolidate FCP XMLs that describe one Project. Export these by selecting the project in the Event or Library and then using the ‘Export XML…’ menu item. From the options for the XML Version choose “Current Version (1.6)”.

From within Worx4 X, select your source XML file using the Browse… button. Worx4 will then report the total length of media used in the project, what the trimmed length will be, and the estimated saving in space.

This version of Worx4 X uses a default handle length of zero seconds.

Select a destination folder to write the trimmed media and the modified XML into. The application will automatically create a sub-folder named after the project.

Press Start to begin processing.Application Use

The Current Task progress bar will indicate how far through the current media file it has worked. The Overall progress bar will show progress of the complete task. Details on the processing are shown in the Information section of the application.

You can press Cancel to stop the processing at any time.

Media is written into the destination folder with each segment being named with the name of the source clip followed by an incrementing number. The new XML is created with the name of the current project. Media that is not trimmed is copied with the original filename with the suffix ‘-Copy’ and a number.

Once complete you can load the XML into FCP X to check that all the media is online. Alternatively you could move it to another workstation or facility for colour grading in Resolve, for example (note this has not been tested), though you may need to relink as the folder will probably end up with a different path.

 

Limitations in current release (V1.0.7) 

We have seen that Worx4 X can trim QuickTime, M4V and MP4 media. It will not currently trim either MXF, QuickTime reference files, mp3 or RED media files.

It will also optionally copy and trim WAV and AIFF if required but with loss of metadata.

QuickTime reference files will be copied to the new directory, but will still be referencing QuickTime files that are in their original location and have not been trimmed.

RED files may appear to have been copied to the destination directory, but in fact only the first of the ‘chunked’ files will have been copied. This may even look ok in FCP X unless you play all the way through the resultant sequence.

For this reason this trial version of Worx4 X is not recommend for use with projects using RED content.

The intention is that if for any reason Worx4 X cannot trim the media, it will copy it whole so that the resulting project is still complete and the media on-line.

 

Under the following circumstances Worx4 X will copy an entire asset:

All of file used All of it is used (once handles are added to it). 
WAV or AIFF It is an uncompressed audio file (WAV or AIFF) and the preferences setting says don't extract from uncompressed audio. 
Complex retiming A usage of the asset contains "complex retiming" (typically retiming that goes backwards). 

Direct retiming

A usage of the asset contains "direct retiming" (this is used when retiming it applied directly to an Asset Clip in the fcpxml, though we are not sure how this is created through the user interface).
Sync clip A usage of the asset is contained in a Sync Clip - we have yet to reliably implement this.
