Hi,
does anyone know how PT manages interleaved multichannel files when importing them? Is there any signature in the file which tells about the track order and does PT read it? I have 5.1 files from several sources and the tracks are mixed up all the time. C is R or LFE/LS/RS vs. LS/RS/LFS. All this film/smpte/dts stuff. it's a pitty that you are never sure. Ambiences are hard to analyse whether R and C is in the right place. ![]() |

Hi: that info should be part of the file header, or the metadata.

I do a lot of 5.1 for network TV and film. I always deliver in six discrete mono files and ask the same to be supplied to me. That way no mistakes are made.

For AAF export I always split the 5.1 tracks into the proper SMPTE order from top to bottom prior to export. |

![]() Do you know from which PT version it works this way? Used to be a complete mess from version to version. Film layout export but SMPTE import and vice versa depending on the version and never really documented or flagged in the fixed bug reports. I just tried this by exporting a 5.0 file via commend-shift-K twice. Once in film and once in SMPTE order set in default path order and both came out at SMPTE order. What's your secret? Many thanks!

Take this FAQ above. I know for a fact I was outputting SMPTE order files in July of 2016 when that FAQ was written. Despite it saying PT can't do that. At some point, I think with PT11 they switched the output to default to SMPTE order. I would ask for an option box to check on export but honestly the only times I deliver interleaved files are for clients that require SMPTE so it hasn't been a big deal. Otherwise I use multi-mono.

Pretty sure PT always exports files in SMPTE format, and always shows them in FILM format. I don't think you have any control at all over either.

Just ran 3 tests. Always exports SMPTE order. Always shows FILM order. Doesn't matter what path order is set in I/O. FAQ is wrong (even used Cubase to import/export 5.1 files from Pro Tools and always the same; in that way it's good news as everything stays outputting/routing correctly)

Obviously it depends on the source if it is creating it, but yes, there's a metadata block of "wave extensible format" in the wave file that Pro Tools (and other audio/video programs) is reading. Cubase has an option to turn off writing that chunk and then things go wrong. Otherwise both Pro Tools and Cubase are writing a SMPTE order chunk and importing into the respective DAWs with correct track order -- Cubase is SMPTE inside the DAW and Pro Tools is FILM inside the DAW.

Reason: bolded important part. if the source isn't creating it, then there's no guidance for Pro Tools |
