FCPx crashing importing XML from DaVinci Resolve

The first two XMLs import into FCP 10.6.5 and all three into 10.7.1 (I'm not running 10.8.1 yet) but all throw the same error:

Encountered an unexpected value. (format="r0": /fcpxm|[1]/ library[1]/event[1]/project[1]/sequence[1]/@format)

The resulting project looks like:

The "r0" format line shows:

<format id="r0" name="FFVideoFormatRateUndefined" height="1620" frameDuration="1/25s" width="2880"/>

I'm certainly no fcpxml expert but I thought "FFVideoFormatRateUndefined" was for audio (and stills?).

Predefined Video Formats | Apple Developer Documentation

Later in the XML it shows that "format="r0"" is used by video clips.

<clip name="B005C007_240809_R3T1.mxf" start="341356/25s" offset="52/25s" duration="28/25s" enabled="1" format="r0" tcFormat="NDF">
    <adjust-transform anchor="0 0" scale="1 1" position="0 0"/>
    <video ref="r2" start="340603/25s" offset="340603/25s" duration="34/1s">
         <audio lane="-1" srcCh="1, 2" ref="r2" start="340603/25s" offset="340603/25s" duration="34/1s"/>
    </video>
</clip>

As a test I edited the fcpxml and changed "FFVideoFormatRateUndefined" to "FFVideoFormat1080p25" and the XML imported without error. The project timeline looked the same as the other imports. Maybe 2880x1620 isn't supported? Try editing the XML like this and see if it imports.

Interestingly, the ARRI site for the Alexa LF doesn't list 2880x1620 as a capture size.

I don't know what is causing your problem but I can confirm everything works OK with 1080p media selecting FCPXML 1.11 Files

As FCP has crashed you must definitely delete the preferences before proceeding.

Not necessarily. We can still see if the xml imports correctly. We can check that the project structure is what it’s supposed to be. Indeed, this may help pinpoint the problem: if the OP is able to import the xml when the media is not available, it would suggest a problem with some of the media instead of the xml.

What does format="r0" mean?

The r0, r1, etc are just sequentially numbered identifiers that are later referenced in the xml.

In this case the problem seems to have been very aptly described by terryb: the r0 format number has undefined width and height, and then there are clips using this r0 format identifier.

I recommend that you do as terryb suggested and let us know.

You need to open the xml file in a text editor and just do the replace of

"FFVideoFormatRateUndefined"

by

"FFVideoFormat1080p25"

Then save the file and try to open it.

I don't believe there's a way to view ARRI RAW files within FCP. I asked Chris Hocking if he planned something like BRAW for ARRI RAW and it sounded like there wasn't enough demand to warrant the effort. The free ARRI Reference Tool can transcode to ProRes (up to 4444 XQ but I don't see an option for Raw).

All 3 import into FCP 10.8.1 but show this warning.

Everything is offline of course as in Terry's screenshots.

Post a link to the fcpxml and we can test to see if it imports.
