Worx4 X – a way to trim Project media

[Craig Seeman]

People have been asking for this feature in FCPX for a long time. It took a third party to do it.
Of course Apple will promptly including it in the next major update ????

Worx4 X

Note the limitations though. This may well be the same things Apple is up against (and therefore haven’t implemented yet).

[Noah Kadner]

Worx works like a charm and is incredibly fast. If you are heavy on shooting ratio and light on storage space, this is the app you’re looking for.

Although I’m concerned by

Worx4 X will not currently trim either MXF, M4A(AAC), AC3, CAF or mp3 media files, the whole file will be copied.

Since that would mean Sony cameras which use MXF aren’t trimmed.

WAV or AIFF files will not be trimmed if the preferences are set to ‘Copy audio files without losing metadata’. Please set this option on first installation.

This too. It’s why I think Apple hasn’t implemented it. I believe there are challenges to trimming certain formats without losing metadata.

[Noah Kadner]

Probably more because all of those long-GOP formats lose major quality when re-encoded. I don’t follow how that’s Apple’s fault. If every camera recorded to ProRes instead of H.264 we’d be all set.

Long GOP I understand why it doesn’t trim (and honestly, those are usually smaller files anyway), but MXF files like XAVC that are intraframe, would be nice to have.

I really want to use this product as I really need it. I currently use Resolve for this and would love something much simpler, But not having MXF is a show stopper. What would be really nice is a trim and transcode to, say 444 or XQ.

Optimizing everything first, sort of defeats the purpose of trimming.

[Noah Kadner] “I don’t follow how that’s Apple’s fault.”
It’s not Apple’s fault but given that many cameras record in Long GOP, Apple decided not to complicate things (IMHO). Hence no media manage feature.
Although I’d point out there are Intra Frame MXF codecs so not all MXF is Long GOP.
Of course what Apple could do is allow you to Optimize (make ProRes) XDCAM variants (XAVC-L for example) which it doesn’t do now.

If you could convert ALL VIDEO to ProRes then they could implement Media Management.

[Noah Kadner]

If all you want is transcode to ProRes you can do this yourself with any number of dailies prep apps. I’d love it if FCPX made my dinner too.

H.264 uses much less hard disk space and requires much less sustained data transfer speeds than Pro Res. A lot of SD cards will not sustain writing speeds to record Pro Res at 4k. H.264 gives a good clean image without need for a lot of storage space or super fast storage type media.

Long GOP media could be trimmed losslessly. You’d just have constrain the trimming to GOP boundaries.

I’d say you’re right.

Personally this is nothing I need or miss, since I archive archive copies of all cards and media anyway and simply delete all media before archiving the finished library. Which then is obviously very small. This wouldn’t save me anything in my workflow.

[Jeremy Garchow] “trim and transcode to, say 444 or XQ.”

Huh? Wait. Isn’t the whole point of this to save space??

And apparently some people haven’t heard of the differences between ProRes’ and H.264 color space for starters, or that there are already endless cameras that record to ProRes to SD just fine, but oh well.
