Hi Ross,

There are only two options, the preference would be for AVFoundation to support CRM, this can only come about if enough people ask Apple for it (users tend to have more weight with Apple than we do :-)

The second is us pushing Canon for an SDK for CRM, and then incorporating this into the X2pro code. Will chase them again.

Yours Sincerely

James

What do we need to do to team up and get Apple / Canon to make this easier!??

Hi Soyburger,

Apologies, there are other threads about CRM, it comes up quite regularly forum.marquisbroadcast.com/4-media-and-formats/1744-canon-raw-lite-crm-file-support.html

Essentially the media needs to be transcoded as it is not supported in Apples AVFoundation and we do not have an SDK from Cannon to read it natively (i.e. outside of AVFoundation).

Many thanks csinclair for your workaround.

Just a quick update we would need either to implement a CRM SDK from Cannon, so we can support this media just like we support R3D, or Apple need to provide support in AVFoundation. We had asked for the SDK and approached Apple but no movement from either still.

My solution has been to transcode everything using the canon raw development tool to transcode. It will retain the audio channel configuration. Then import the prores transcoded versions into final cut and use those. Then it will work.

I'm having this same issue. I see that the thread is 3 years old and I don't see any solutions offered. Do I need to ditch my C200 or is someone working on a solution to this problem. The word thing is that I'm the only person on my team having this issue and we all have the same setup, but we can't find out what the difference is that's making my .fcpxml not work and theirs work.

Hi Ross,

The way I managed to do it was to use Adobe Media Encoder to transcode my .crm clips to XAVC QFHD Intra Class300 (shouldn't matter which you select). Then I imported those clips into a final cut project, exported the xml and then went through X2Pro completely fine.

Hi James and others on this thread...

Can anyone explain the best way to transcode the CRM audio in Final Cut? I have tried creating Optimised Media, but this doesn't seem to be referenced by the XML export - X2Pro stills fails to read read the CRM clips.

Does anyone have a workaround for transcoding the CRM audio into a format that is referenced by the XML and hence readable by X2Pro?

thanks,
Ross

Dear Erim,

If you are seeing the same error message "Track number exceeds number of tracks in asset " then it is likely that the particular asset is marked as having 1 audio track with 3 channels, which indicates a malformed FCP XML, we are not quite sure how we can get around this in the code as fundamentally the XML created is suspect. You might be able to transcode the asset in question to a slightly different format and then replace the existing asset with the new, and then create a new XML referencing this new asset.

What version of FCPX are you using ?

Yours sincerely

James

I am experiencing the same issue with audio of C200 CRM Files out of FCPX. Is there any solution?

The same issue was reported by Pedoussaut, essentially the XML is bad for the same reason. Unfortunately Pedoussaut's post got lost in an upgrade on the forum. Apologies to you, Pedoussaut.

Hi Chris,

Apologies for the delay.

We have been looking into this and it appears to be a problem with the xml. An audio element is referencing a track that does not exist in an asset. e.g. It references a third track of an asset which only has two tracks. Exporting another xml may allow FCP to create a good xml.

It sounds like the ProRes audio has a different number of tracks to the CRM.

Would you be able to forwards us the xml with the ProRes audio in it ?

Thanks,

I tried swapping original media with ProRes versions, that were transcoded. Does this error mean something changed between my original audio and the ProRes audio that's now being referenced? ( I used a relink technique to point instead of my .CRM files, to my new ProRes .MOV files).

The following fatal errors were found:
Processing Audio element
Processing element VideoElement
Processing element AudioElement
Extracting audio
Extracting Audio
Processing element SequenceElement
Track number exceeds number of tracks in asset [A016C818_170222TR_CANON]
Processing element SpineElement
Processing element ClipElement
Processing element ProjectElement

Actually, in the meantime I’m wondering as a workaround if I detach audio and remove all remaining video clips from th timeline if that would work on export for trimming handles. I’m away from my desk otherwise I’d try. but wondering if that would work.
