Resolve 15.2.1 fcpxml export/import broken?

Can someone validate that I'm not the only one with this issue.

1. take any video clip with a stereo audio track and go into clip attributes and update it to be dual mono
2. create a new timeline and drop the clip on it, and you get two separate audio tracks
3. export the timeline to any version (1.3 to 1.8) of final cut pro x
4. import the xml file you just created.

Every time I do this, the clip is imported with stereo audio.

It's slightly infuriating that resolve can't properly import an xml file it created.

I only get a single mono track, not stereo.

I checked this again this morning and I'm getting the same thing.

Are you sure the fcpxml specification can actually handle the distinction? I doubt it.... XML has always been pretty crude, you celebrate if the clips are in the right order.

The apple documentation is fairly horrendous, but as I read it you should be able to import or export a clip as dual mono even though the source clip is stereo.

take a look at this page. speciffically check listing 2-1 and the use of the audio-channel-source element.

I don't own final cut, so I can't validate it myself directly.

The XML exported from Resolve works as expected in FCPX. It does not work the same way when re-imported into Resolve 15.2.1

Thanks for checking on FCPX Peter, your test shows something is wrong with Resolve when it comes to importing and not exporting.

FCP7 XML behaves correctly. My tests of multi-track audio timeline export to fcpxml V1.8 format shows correct import in FCPX but only one channel in the imported timeline in Resolve 15.2.1.

This is odd as a test FCPX multichannel audio project reads correctly in R15, but re-importing the multichannel timeline fcpxml which was exported from R15 shows this issue.

That is odd for sure.

Peter, can you do me a favor and post the xml generated by FCP and the one generated by Resolve? I'd like to take a look at them and see what resolve is doing wrong.

It would also be be helpful as I'm going back and forth in email with customer services about the issue.

Summary:

FCPXML to Resolve works correctly. Resolve FCPXML to FCPX works correctly.
I'm not sure when one would need to export from Resolve in FCPXML format to re-import to Resolve.
FCP7 xml (Premiere format) works correctly too.
I'll test AAF format in the next few days.

So a little bit of back story.

I'm a software developer by trade, and videography is a hobby of mine. Speaking as a developer, lets just say that writing an application that can't read files correctly that it created doesn't inspire much confidence.


I found this issue, while trying to work around a current limitation of resolve. As you may or may not know, if you are shooting with multiple cameras and an external audio recorder you can't sync everything up in resolve even if you're using timecode. You really only have two options, and neither is ideal.

1. You can sync the audio to the video clips so you have complete control over how the audio is handled, but then you have to manually sync video clips on the timeline. This is painfully slow if you have a lot of clips.
2. If you use Multicam you can get all the audio & video clips synced up, but you loose all control over the audio as the only thing you get out of multicam is one audio track.

Since neither of these are acceptable use cases to me, I've been working on a custom application that will generate fcpxml files that have all the audio & video files synced and configured as I want them. The Apple documentation on fcpxml is less than stellar so I've been having to reverse engineer the format, by creating something in resolve, generating a fcpxml export, and then tearing it apart to see what resolve wrote.

this is why I wanted to see the xml file you created in FCP that imported into Resolve correctly.

Well, here is the proof, that resolve isn't capable of properly reading or writing dual mono fcpxml files. This really needs fixed, because as a developer, if this was my code, I'd be embarrassed.

I spent several hours yesterday, updating my wife's old imac, so I could download and install the trail version of fcpx.

Here is the xml out of Resolve. when I import this into resolve I get a singe stereo track no matter what i do.

Here it is out of fcpx with just the video source path change to work on my machine. When I import this this I do get dual mono tracks, however its just the left track repeated, and thus useless.

You can ignore all the meta data and what not, all that really matters is the clip from resolve and the asset-clip from fcpx. from my reading of the apple documentation, both should technically work, but resolve doesn't process either one properly.

Sorry, I've been reading this for a little time, but was too busy to butt in.

Resolve's ability to understand audio in exporting or importing FCPXMLs or XMLs are borken, they do not recognise dual mono or multi-track audio.

I had eight multi-track audio imported via FCPXML and it was basically recognised as 8 x eight multi-track audio (I've simplified some things here), which only play as very loud white noise. I had to manually delete them and decompose for it to work.

Resolve's ability to understand audio in exporting or importing FCPXMLs or XMLs are borken, they do not recognise dual mono or multi-track audio.

I can confirm this as well, because I was testing this just a little bit ago with a poly wav out of a zoom F4.

The two following fcpxml files both yield dual mono audio, but its the same channel form source file, so again not useful. I mean come on, poly wav files are an industry standard and not being able to read them is pretty bad.

I'm getting independent mono tracks importing from fcpxml, but the track arrangement is reversed.
Tracks 1234 import as tracks 4321. If I change the assigned (sub)roles on tracks 3 & 4 to music 1 & 2, then it's even more weird as it imports as 2341. I suspect the FCPX roles are the issue here. I can't seem to replicate the dual mono issue as it works ok for me.

The roles shouldn't really matter, because they aren't technically needed as i read the spec. Fcpx documentations says it will auto assign them if need be.


The only way i can find to make everything work as expected is to literally break all the tacks (audio & video) out into standalone clips and then import them as linked clips. while this seems to work so far in my testing, is a ridiculous amount of prepossessing that shouldn't need to be done.

I also had that.

I'll expand on my problem. This could be my editors been on a "wrong" workflow, but anything they've sync and exported on FCPXML, when I import into DaVinci, they become compound clips, which would have been fine. But the audio within the compound clip is 8 tracks of the 8 track audio compound clips, which means at anyone time, it's trying to read 64 audio tracks, which breaks DaVinci.

Its been two weeks now, and my support ticket has not gone anywhere, so it seems this must not be a very important issue for BM.

I heard back from Tech support today. They have been able to duplicate the issue I'm seeing so they have forwarded it development to address.
