FCP X destroying audio edits in XML output
I’m not sure what’s going on, but I’ve now seen this on every project I’ve worked on using 3 different unrelated systems. This includes projects converted from 10.1.2 to 10.1.3, as well as started from scratch in 10.1.3.
I’ll edit an audio track in FCP X using connected clips. Sources are AIF or WAV or detached audio from a video file. I’ll tweak as needed and add fade handles. When I export an FCPXML to convert and send to another program, the audio edits are completely destroyed. This includes XML conversion and bringing it into FCP 7 or a DAW or converting AAF. No difference. The results are audio clips that are upcut and/or cut short (probably where the fade handles were). But some are the wrong portion of the clip. In one project (a 10 min. teaser video) some files are completely clipped, except for a few frames.
The bottom line is that I have been completely unable for several projects to export any sort of functional file to hand off to an audio editor/mixer. Everything sounds and looks fine inside FCP X. And I can successfully export stems using roles, but then my work is baked in, which is NEVER what you ideally want to do. I can’t believe that I’m the only one this is happening to. It was fine prior to 10.1.2. Thoughts?

Tried that to. Same problem. The issues seem to be in the original FCPXML output. FWIW, I’ve had no issues with picture exports.
Here’s a simple test that I just did at home tonight. A completely fresh library and project. Project is 1080p/23.98, 48kHz audio.
Take a few audio and video clips. Audio can be AIFF or WAV. Use VO and music. Build a VO track using overlapping connected clips and add fade handles to each stretching into the audio section (not just over blank space). Place a music bed underneath as a connected clip. Put a few picture clips above – also as connected clips.
Export an XML, convert using Xto7 and bring into FCP7. Listen to the VO track. Are all the clips in the correct place? Is the audio up-cut at the heads or clipped at the tails of any clips? Is it the correct part of the take?
This is with FCP X 10.1.3 running on OS X 10.9.4 on an older Mac Pro tower.

What is your original source material?

[Jeremy Garchow] “What is your original source material?”
On the various projects, it’s all over the place. This latest test was ProResHQ for picture and AIF for audio.

I just did a quick test, everything came over, fade handles, transitions, and all.
I’ve seen bad translations when the incoming tc is weird, or added from an app that uses an older calculation method.

No TC on the tested source clips from tonight as these are music and VO tracks.

Let me run another test.
My music was in the primary.

Still can’t get it to fail. Everything plays back OK, looks like this:

Not you, but not sure it’s the fcpxml either. I recreated your timeline, and sure enough, the VO clips shifted in place. But… importing the fcpxml directly into logic, and then into Resolve 11, and lining up a QT movie of the FCP X project, it was perfectly fine. Something’s happening in the Xto7 translation, and maybe the same issue with the X2Pro translation. (didn’t try that) Here’s the timeline pix, from bottom to top (oops):
FCP X original,
FCP 7, (obviously shifted, check the fades)
Logic with the QT from the original above, looks and plays fine),
R11 with QT ref on the bottom track, also plays fine. So… mis-translation? Might want to send the original fcpxml, translation and Fcp X and 7 test projects to Greg….

It did the same thing, albeit less so. Compare your FCP 7 fades to the FCP X fades. See how the FCP 7 fades extend beyond the clip boundaries? Clips are in the right place, but the audio slipped. Make a QT from X and line it up in 7 and I bet you’ll hear it…
